🛶 CANU v1.6.13-develop

CANU (CSM Automatic Network Utility) will float through a Shasta network and make switch setup and validation a breeze.

CANU can be used to:

Check if switches (Aruba, Dell, or Mellanox) on a Shasta network meet the firmware version requirements
Check network cabling status using LLDP
Validate BGP status
Validate that SHCD spreadsheets are configured correctly and pass a number of checks
Validate an SHCD against actual network cabling status to check for mis-cabling
Generate switch configuration for an entire network
Convert SHCD to CCJ (CSM Cabling JSON)
Use CCJ / Paddle to validate the network and generate network config
Run tests against the mgmt network to check for faults/inconsistencies.
Backup switch configs.

Quickstart Guide

To checkout a fresh system using CSI:

Make a new directory to save switch IP addresses: mkdir ips_folder, cd ips_folder
Parse CSI files and save switch IP addresses: canu init --sls-file sls_input_file.json --out ips.txt
Check network firmware: canu report network firmware --csm 1.2 --ips-file ips.txt
Check network cabling: canu report network cabling --ips-file ips.txt
Validate BGP status: canu validate network bgp --ips-file ips.txt --verbose
Validate cabling: canu validate network cabling --ips-file ips.txt

If you have the system's SHCD, there are even more commands that can be run

Validate the SHCD: canu validate shcd --shcd SHCD.xlsx
Validate the SHCD against network cabling: canu validate shcd-cabling --shcd SHCD.xlsx --ips-file ips.txt
Generate switch config for the network: canu generate network config --shcd SHCD.xlsx --sls-file sls_input_file.json --folder configs
Convert the SHCD to CCJ: canu validate shcd --shcd SHCD.xlsx --json --out paddle.json

If you have the system's CCJ

Validate the Paddle / CCJ: canu validate paddle --ccj paddle.json
Validate the CCJ against network cabling: canu validate paddle-cabling --ccj paddle.json --ips-file ips.txt
Generate switch config for the network: canu generate network config --ccj paddle.json --sls-file sls_input_file.json --folder configs

Paddle / CCJ

The paddle or CCJ (CSM Cabling JSON) is a JSON representation of the network. There are many benefits of using the CCJ:

The CCJ schema has been validated using paddle-schema.json
The paddle has been architecturally validated to ensure all connections between devices are approved
All port connections between devices have been checked using the CANU model to ensure speed, slot choice, and port availability has been confirmed
The CCJ is machine readable and therefore easy to build additional tooling around
There are less flags that need to be used when reading the CCJ vs the SHCD

The SHCD can easily be converted into CCJ by using canu validate shcd --shcd SHCD.xlsx --json --out paddle.json

Initialization

Details

To help make switch setup a breeze. CANU can automatically parse SLS JSON data - including CSI sls_input_file.json output or the Shasta SLS API for switch IPv4 addresses.

CSI Input

In order to parse CSI output, use the --sls-file FILE flag to pass in the folder where an SLS JSON file is located.

The CSI sls_input_file.json file is generally stored in one of two places depending on how far the system is in the install process.

Early in the install process, when running off of the LiveCD the CSI sls_input_file.json file is normally found in the the directory /var/www/ephemeral/prep/SYSTEMNAME/
Later in the install process, the CSI sls_input_file.json file is generally in /mnt/pitdata/prep/SYSTEMNAME/
The SLS file can also be obtained from an NCN that's in the k8s cluster by running cray sls dumpstate list --format json
The switch IPs will be read from the 'NMN' network, if a different network is desired, use the --network flag to choose a different one e.g. (CAN, MTL, NMN).

To get the switch IP addresses from CSI output, run the command:

$ canu init --sls-file SLS_FILE --out output.txt
8 IP addresses saved to output.txt

SLS API Input

To parse the Shasta SLS API for IP addresses, ensure that you have a valid token. The token file can either be passed in with the --auth-token TOKEN_FILE flag, or it can be automatically read if the environmental variable SLS_TOKEN is set. The SLS address is default set to api-gw-service-nmn.local, if you are operating on a system with a different address, you can set it with the --sls-address SLS_ADDRESS flag.

To get the switch IP addresses from the Shasta SLS API, run the command:

$ canu init --auth-token ~./config/cray/tokens/ --sls-address 1.2.3.4 --out output.txt
8 IP addresses saved to output.txt

The output file for the canu init command is set with the --out FILENAME flag.

Report Switch Firmware

Details

CANU checks the switch firmware version against the standard in the canu.yaml file found in the root directory.

The CSM version is required to determine the firmware to validate against, you can pass it in with --csm like --csm 1.2.

To check the firmware of a single switch run: canu report switch firmware --csm 1.2 --ip 192.168.1.1 --username USERNAME --password PASSWORD

$ canu report switch firmware --csm 1.2 --ip 192.168.1.1 --username USERNAME --password PASSWORD
🛶 - Pass - IP: 192.168.1.1 Hostname:sw-spine-001 Firmware: GL.10.06.0010

Report Network Firmware

Details

Multiple switches on a network (Aruba, Dell, or Mellanox) can be checked for their firmware versions. The IPv4 addresses of the switches can either be entered comma separated, or be read from a file. To enter a comma separated list of IP addresses to the ---ips flag. To read the IP addresses from a file, make sure the file has one IP address per line, and use the flag like --ips-file FILENAME to input the file.

The CSM version is required to determine the firmware to validate against, you can pass it in with --csm like --csm 1.2.

An example of checking the firmware of multiple switches: canu report network firmware --csm 1.2 --ips 192.168.1.1,192.168.1.2 --username USERNAME --password PASSWORD

$ canu report network firmware --csm 1.2 --ips 192.168.1.1,192.168.1.2,192.168.1.3,192.168.1.4 --username USERNAME --password PASSWORD

------------------------------------------------------------------
    STATUS  IP              HOSTNAME            FIRMWARE
------------------------------------------------------------------
 🛶 Pass    192.168.1.1     test-switch-spine01 GL.10.06.0010
 🛶 Pass    192.168.1.2     test-switch-leaf01  FL.10.06.0010
 ❌ Fail    192.168.1.3     test-wrong-version  FL.10.05.0001   Firmware should be in range ['FL.10.06.0001']
 🔺 Error   192.168.1.4


Errors
------------------------------------------------------------------
192.168.1.4     - HTTP Error. Check that this IP is an Aruba switch, or check the username and password

Summary
------------------------------------------------------------------
🛶 Pass - 2 switches
❌ Fail - 1 switches
🔺 Error - 1 switches
GL.10.06.0010 - 1 switches
FL.10.06.0010 - 1 switches
FL.10.05.0010 - 1 switches

When using the network firmware commands, the table will show either: 🛶 Pass, ❌ Fail, or 🔺 Error. The switch will pass or fail based on if the switch firmware matches the canu.yaml

Output to a File

To output the results of the switch firmware or network firmware commands to a file, append the --out FILENAME flag

JSON

To get the JSON output from a single switch, or from multiple switches, make sure to use the --json flag. An example json output is below.

$ canu network firmware --csm 1.2 --ips 192.168.1.1,192.168.1.2 --username USERNAME --password PASSWORD --json

{
    "192.168.1.1": {

    },
}

Report Switch Cabling

Details
CANU can also use LLDP to check the cabling status of a switch. To check the cabling of a single switch run: canu report switch cabling --ip 192.168.1.1 --username USERNAME --password PASSWORD

$ canu report switch cabling --ip 192.168.1.1 --username USERNAME --password PASSWORD

Sometimes when checking cabling using LLDP, the neighbor does not return any information except a MAC address. When that is the case, CANU looks up the MAC in the ARP table and displays the IP addresses and vlan information associated with the MAC.

Entries in the table will be colored based on what they are. Neighbors that have ncn in their name will be colored blue. Neighbors that have a port labeled (not a MAC address), are generally switches and are labeled green. Ports that are duplicated, will be bright white.

Report Network Cabling

Details

The cabling of multiple switches (Aruba, Dell, or Mellanox) on a network can be checked at the same time using LLDP. The IPv4 addresses of the switches can either be entered comma separated, or be read from a file. To enter a comma separated list of IP addresses to the ---ips flag. To read the IP addresses from a file, make sure the file has one IP address per line, and use the flag like --ips-file FILENAME to input the file.

An example of checking the cabling of multiple switches: canu report network cabling --ips 192.168.1.1,192.168.1.2 --username USERNAME --password PASSWORD

There are two different --view options, switch and equipment.

The --view switch option displays a table for every switch IP address passed in showing connections. This is the same view as shown in the above example of checking single switch cabling.
The --view equipment option displays a table for each mac address connection. This means that servers and switches will both display incoming and outgoing connections.

An example of checking the cabling of multiple switches and displaying with the equipment view: canu network cabling --ips 192.168.1.1,192.168.1.2 --username USERNAME --password PASSWORD --view equipment

$ canu report network cabling --ips 192.168.1.1,192.168.1.2 --username USERNAME --password PASSWORD --view equipment

Validate SHCD

Details

CANU can be used to validate that an SHCD (SHasta Cabling Diagram) passes basic validation checks.

The --architecture / -a flag is used to set the architecture of the system, either TDS, Full, or V1..
Use the --tabs flag to select which tabs on the spreadsheet will be included.
The --corners flag is used to input the upper left and lower right corners of the table on each tab of the worksheet. The table should contain the 11 headers: Source, Rack, Location, Slot, (Blank), Port, Destination, Rack, Location, (Blank), Port. If the corners are not specified, you will be prompted to enter them for each tab.

To check an SHCD run: canu validate shcd -a tds --shcd FILENAME.xlsx --tabs 25G_10G,NMN,HMN --corners I14,S25,I16,S22,J20,T39

Validate Paddle and Cabling

Details

CANU can be used to validate aCCJ paddle against the current network cabling.

The --csm flag is used to set the CSM version of the system.
The --ccj flag is used to input the CCJ file.
To enter a comma separated list of IP addresses to the ---ips flag. To read the IP addresses from a file, make sure the file has one IP address per line, and use the flag like --ips-file FILENAME to input the file.

To validate an SHCD against the cabling run: canu validate paddle-cabling --csm 1.2 --ccj paddle.json --ips 192.168.1.1,192.168.1.2 --username USERNAME --password PASSWORD

$ canu validate paddle-cabling --csm 1.2 --ccj paddle.json --ips 192.168.1.1,192.168.1.2 --username USERNAME --password PASSWORD

Validate Network BGP

Details

CANU can be used to validate BGP neighbors. All neighbors of a switch must return status Established or the verification will fail.

The default asn is set to 65533 if it needs to be changed, use the flag --asn NEW_ASN_NUMBER to set the new number

If you want to see the individual status of all the neighbors of a switch, use the --verbose flag.

To validate BGP run: canu validate network bgp --ips 192.168.1.1,192.168.1.2 --username USERNAME --password PASSWORD

$ canu validate network bgp --username USERNAME --password PASSWORD

BGP Neighbors Established
--------------------------------------------------
PASS - IP: 192.168.1.1 Hostname: sw-spine01
PASS - IP: 192.168.1.2 Hostname: sw-spine01

If any of the spine switch neighbors for a connection other than Established, the switch will FAIL validation.

Generate Switch Config

Details
To see all the lags that are generated, see lags

CANU can be used to generate switch config.

In order to generate switch config, a valid SHCD or CCJ must be passed in and system variables must be read in from any SLS data, including CSI output or the SLS API.

CSI Input

In order to parse CSI output, use the --sls-file FILE flag to pass in the folder where the sls_file.json file is located.

The sls_input_file.json file is generally stored in one of two places depending on how far the system is in the install process.

Early in the install process, when running off of the LiveCD the sls_input_file.json file is normally found in the the directory /var/www/ephemeral/prep/SYSTEMNAME/
Later in the install process, the sls_input_file.json file is generally in /mnt/pitdata/prep/SYSTEMNAME/

SLS API Input

To parse the Shasta SLS API for IP addresses, ensure that you have a valid token. The token file can either be passed in with the --auth-token TOKEN_FILE flag, or it can be automatically read if the environmental variable SLS_TOKEN is set. The SLS address is default set to api-gw-service-nmn.local, if you are operating on a system with a different address, you can set it with the --sls-address SLS_ADDRESS flag.

Paddle / CCJ Input

The --csm flag is used to set the CSM version of the system.
The --ccj flag is used to input the CCJ file.

To generate switch config run: canu generate switch config --csm 1.2 --ccj paddle.json --sls-file SLS_FILE --name SWITCH_HOSTNAME --out FILENAME

SHCD Input

The --csm flag is used to set the CSM version of the system.
The --architecture / -a flag is used to set the architecture of the system, either TDS, Full, or V1..
Use the --tabs flag to select which tabs on the spreadsheet will be included.
The --corners flag is used to input the upper left and lower right corners of the table on each tab of the worksheet. The table should contain the 11 headers: Source, Rack, Location, Slot, (Blank), Port, Destination, Rack, Location, (Blank), Port. If the corners are not specified, you will be prompted to enter them for each tab.

To generate config for a specific switch, a hostname must also be passed in using the --name HOSTNAME flag. To output the config to a file, append the --out FILENAME flag.

To generate switch config run: canu generate switch config --csm 1.2 -a full --shcd FILENAME.xlsx --tabs 'INTER_SWITCH_LINKS,NON_COMPUTE_NODES,HARDWARE_MANAGEMENT,COMPUTE_NODES' --corners 'J14,T44,J14,T48,J14,T24,J14,T23' --sls-file SLS_FILE --name SWITCH_HOSTNAME --out FILENAME

$ canu generate switch config --csm 1.2 -a full --shcd FILENAME.xlsx --tabs INTER_SWITCH_LINKS,NON_COMPUTE_NODES,HARDWARE_MANAGEMENT,COMPUTE_NODES --corners J14,T44,J14,T48,J14,T24,J14,T23 --sls-file SLS_FILE --name sw-spine-001

hostname sw-spine-001
user admin group administrators password plaintext
bfd
no ip icmp redirect
vrf CAN
vrf keepalive
...

Generate Switch Configs Including Custom Configurations

Pass in a switch config file that CANU will inject into the generated config. A use case would be to add custom site connections. This config file will overwrite previously generate config.

The custom-config file type is YAML and a single file can be used for multiple switches. You will need to specify the switch name and what config inject. The custom-config feature is using the hierarchical configuration library, documentation can be found here https://netdevops.io/hier_config/.

#### Generate Switch Config while preserving LAG #s

This option allows you to generate swtich configs while preserving the lag #s of the previous running config.

The use case for this is if you have a running system and you don't want to take an outage to renumber the LAGs.

It requires a folder with the config/s backed up.

The recommended way to back these configs up is with **[Backup Network](#backup-network)**

canu generate switch config -a v1 --csm 1.0 --ccj ccj.json --sls-file sls_input_file.json --name sw-spine-001 --preserve ../backup_configs/


### Generate Network Config

**[Details](docs/generate_network_config.md)**<br>
To see all the lags that are generated, see [lags](docs/lags.md)

CANU can also generate switch config for all the switches on a network.

In order to generate network config, a valid SHCD or CCJ must be passed in and system variables must be read in from either CSI output or the SLS API. The instructions are exactly the same as the above **[Generate Switch Config](#generate-switch-config)** except there will not be a hostname and a folder must be specified for config output using the `--folder FOLDERNAME` flag.

To generate switch config from a CCJ paddle run: `canu generate network config --csm 1.2 --ccj paddle.json --sls-file SLS_FILE --folder FOLDERNAME`

To generate switch config from SHCD run: `canu generate network config --csm 1.2 -a full --shcd FILENAME.xlsx --tabs 'INTER_SWITCH_LINKS,NON_COMPUTE_NODES,HARDWARE_MANAGEMENT,COMPUTE_NODES' --corners 'J14,T44,J14,T48,J14,T24,J14,T23' --sls-file SLS_FILE --folder FOLDERNAME`

```bash
$ canu generate network config --csm 1.2 -a full --shcd FILENAME.xlsx --tabs INTER_SWITCH_LINKS,NON_COMPUTE_NODES,HARDWARE_MANAGEMENT,COMPUTE_NODES --corners J14,T44,J14,T48,J14,T24,J14,T23 --sls-file SLS_FILE --folder switch_config

Generate Network Config With Custom Config Injection

This option allows extension and maintenance of switch configurations beyond plan-of-record. A YAML file expresses custom configurations across the network and these configurations are merged with the plan-of-record configurations.

WARNING: Extreme diligence should be used applying custom configurations which override plan-of-record generated configurations. Custom configurations will overwrite generated configurations! Override/overwrite is by design to support and document cases where site-interconnects demand "nonstandard" configurations or a bug must be worked around.

The instructions are exactly the same as Generate Switch Config with Custom Config Injection

To generate network configuration with custom config injection run

canu generate network config --csm 1.2 -a full --shcd FILENAME.xlsx --tabs INTER_SWITCH_LINKS,NON_COMPUTE_NODES,HARDWARE_MANAGEMENT,COMPUTE_NODES --corners J14,T44,J14,T48,J14,T24,J14,T23 --sls-file SLS_FILE --folder switch_config --custom-config CUSTOM_CONFIG_FILE.yaml

Generate Network Config while preserving LAG #s

This option allows you to generate swtich configs while preserving the lag #s of the previous running config.

The use case for this is if you have a running system and you don't want to take an outage to renumber the LAGs.

It requires a folder with the config/s backed up.

The recommended way to back these configs up is with Backup Network

$ canu generate network config --csm 1.0 -a full --shcd FILENAME.xlsx --tabs INTER_SWITCH_LINKS,NON_COMPUTE_NODES,HARDWARE_MANAGEMENT,COMPUTE_NODES --corners J14,T44,J14,T48,J14,T24,J14,T23 --sls-file SLS_FILE --folder switch_config --preserve FOLDER_WITH_SWITCH_CONFIGS

Validate Switch Config

Details

After config has been generated, CANU can validate the generated config against running switch config. The running config can be from either an IP address, or a config file.

To get running config from an IP address, use the flags --ip 192.168.1.1 --username USERNAME --password PASSWORD.
To get running config from a file, use the flag --running RUNNING_CONFIG.cfg instead.

After running the validate switch config command, you will be shown a line by line comparison of the currently running switch config against the config file that was passed in. You will also be given a list of remediation commands that can be typed into the switch to get the running config to match the config file. There will be a summary table at the end highlighting the most important differences between the configs.

Lines that are red and start with a - are in the running config, but not in the config file
Lines that are green and start with a + are not in the running config, but are in the config file
Lines that are blue and start with a ? are attempting to point out specific line differences

To validate switch config run: canu validate switch config --ip 192.168.1.1 --username USERNAME --password PASSWORD --generated SWITCH_CONFIG.cfg

$ canu validate switch config --ip 192.168.1.1 --generated sw-spine-001.cfg

Validate Network Config

Details
Aruba support only.

The validate network config command works almost the same as the above validate switch config command. There are three options for passing in the running config:

A comma separated list of ips using --ips 192.168.1.1,192.168.1.
A file of ip addresses, one per line using the flag --ips-file ips.txt
A directory containing the running configuration --running RUNNING/CONFIG/DIRECTORY

A directory of generated config files will also need to be passed in using --generated GENERATED/CONFIG/DIRECTORY. There will be a summary table for each switch highlighting the most important differences between the running switch config and the generated config files.

To validate switch config run: canu validate network config --ips-file ips.txt --username USERNAME --password PASSWORD --generated /CONFIG/FOLDER

$ canu validate network config --csm 1.2 --ips-file ips.txt --generated /CONFIG/FOLDER

File Output and JSON

To output the results of the config validation command to a file, append the --out FILENAME flag. To get the results as JSON, use the --json flag.

Cache

There are several commands to help with the canu cache:

canu cache location will tell you the folder where your cache is located
canu cache print will print a colored version of your cache to the screen
canu cache delete will delete your cache file, the file will be created again on the next canu command

Test The Network

CANU has the ability to run a set of tests against all of the switches in the management network. It is utilizing the nornir automation framework and additional nornir plugins to do this.

More info can be found at

Required Input You can either use an SLS file or pull the SLS file from the API-Gateway using a token.

--sls-file
--auth-token

Options

--log outputs the nornir debug logs
--network [HMN|CMN] This gives the user the ability to connect to the switches over the CMN. This allows the use of this tool from outside the Mgmt Network. The default network used is the HMN.
--json outputs the results in json format.
--password prompts if password is not entered
--username defaults to admin

Adding tests

Additional tests can be easily added by updating the .yaml file at canu/test/*/test_suite.yaml More information on tests and how to write them can be found at https://nornir.tech/2021/08/06/testing-your-network-with-nornir-testsprocessor/

Example test

- name: Software version test
  task: show version
  test: contains
  pattern: "10.08.1021"
  err_msg: Software version is wrong
  device:
    - cdu
    - leaf
    - leaf-bmc
    - spine

This test logs into the cdu, leaf, leaf-bmc, and spine switches and runs the command show version and checks that 10.09.0010 is in the output. If it's not the test fails.

Backup Network

Canu can backup the running configurations for switches in the management network. It backs up the entire switch inventory from SLS by defualt, if you want to backup just one switch use the --name flag.

Required Input You can either use an SLS file or pull the SLS file from the API-Gateway using a token.

--sls-file
--folder "Folder to store running config files"

Options

--log outputs the nornir debug logs
--network [HMN|CMN] This gives the user the ability to connect to the switches over the CMN. This allows the use of this tool from outside the Mgmt Network. The default network used is the HMN.
--password prompts if password is not entered
--username defaults to admin
--unsanitized Retains sensitive data such as passwords and SNMP credentials. The default is to sanitize the config.
--name The name of the switch that you want to back up. e.g. 'sw-spine-001'

Example

  $ canu backup network --sls-file ./sls_input_file.json --network CMN --folder ./ --unsanitized

Send Command

Canu can send commands to the switches via the CLI. This is primarily used for show commands since we do not elevate to configuration mode.

You can either use an SLS file or pull the SLS file from the API-Gateway using a token.

--sls-file
--log outputs the nornir debug logs
--network [HMN|CMN] This gives the user the ability to connect to the switches over the CMN. This allows the use of this tool from outside the Mgmt Network. The default network used is the HMN.
--command command to send to the switch/switches.
--password prompts if password is not entered
--username defaults to admin
--name The name of the switch that you want to back up. e.g. 'sw-spine-001'

Examples

  canu send command --sls-file ./sls_input_file.json --network cmn --command "show banner exec" --name sw-spine-001

Report Network Version

Canu reports the version of configuration on the switch. It reads the exec baner of all the switches and outputs to the screen.

Options

--sls-file
--network [HMN|CMN] This gives the user the ability to connect to the switches over the CMN. This allows the use of this tool from outside the Mgmt Network. The default network used is the HMN.
--password prompts if password is not entered
--username defaults to admin

Example

canu report network version --sls-file ../sls_input_file.json --network cmn
