SUMMARY

snmp user output behavior varies quite a bit for the different nxos platforms and required several workarounds:

  • N5K/N6k

    • These platforms do not support structured output for show snmp user.
    • The current code lands in an except clause when the output is not structured; so I added a new get_non_structured_snmp_user method to scrape the state from the regular cli output if it's present.

  • N9K-F

    • The group data in the JSON output is different for this platform; it has a different key (just group instead of TABLE_groups or group_names) and it is not indexed
    • For a single group the value is a string, for multiple groups it's a list

  • sanity test cleanup

    • N5K/N6K/N9K-F platforms will reject no snmp user <name> <role> when it's the last role defined for the user.
    • workaround is to use nxos_user to remove the user

nxos_snmp_user: platform fixes for get_snmp_user
d3d0044 
snmp user output behavior varies quite a bit for the different nxos platforms and required several workarounds:

- N5K/N6k
 - These platforms do not support structured output for `show snmp user`.
 - The current code lands in an `except` clause when the output is not structured; so I added a new `get_non_structured_snmp_user` method to scrape the state from the regular cli output if it's present.

- N9K-F
 - The `group` data in the JSON output is different for this platform; it has a different key (just `group` instead of `TABLE_groups` or `group_names`) and it is not indexed
 - For a single group the value is a string, for multiple groups it's a list

- sanity
 - N5K/N6K/N9K-F platforms will reject `no snmp user <name> <role>` when it's the last role defined for the user.
 - workaround is to use `nxos_user` to remove the user

- Changes validated on:
