index and filename for cisco_nxos_show_interfaces_switchport are WRONG

[i-m-d]

Hello,

In the index there is this entry:

cisco_nxos_show_interfaces_switchport.textfsm, .*, cisco_nxos, sh[[ow]] int[[erfaces]] sw[[itchport]]

this entry does not work for me en any Cisco Nexus (i have several types, N3000, N9000, N9500, N7000).

In Nexus CLI there is NO "show interfaces xxx" only "show interface xxx", note the "s" in interface(s).

If i add this entry to index:

cisco_nxos_show_interface_switchport.textfsm, .*, cisco_nxos, sh[[ow]] int[[erface]](?: (?:\S+))? sw[[itchport]]

and do a copy of the file with (s):

cisco_nxos_show_interface_switchport.textfsm

Works perfectly for me.

I hope this is usefull.

Hello,

In the index there is this entry:

cisco_nxos_show_interfaces_switchport.textfsm, .*, cisco_nxos, sh[[ow]] int[[erfaces]] sw[[itchport]]

With TextFSM, the double square brackets list the optional characters.

The command show interface switchport should have been matched. (But yes, I'll validate too.)

I've not tested this against any N9k yet, but I'll try to remember ... if not tomorrow then possibly Friday.

:dart: What NX-OS version or versions are you running against?

If i add this entry to index:

cisco_nxos_show_interface_switchport.textfsm, .*, cisco_nxos, sh[[ow]] int[erface]? sw[[itchport]]

and do a copy of the file with (s):

cisco_nxos_show_interface_switchport.textfsm

Works perfectly for me.

I hope this is usefull.

Hello,

I need to execute this two commands:

show interface switchport show interface switchport

🎯 What NX-OS version or versions are you running against?

I have several Nexus models and several versions:

N7700 version 8.x N9500 version 10.3.x N9300 versions 9.3.x 10.2.x 10.4.x N3000 versions 7.3.x 9.3.x

I need to execute this two commands:

show interface switchport

This command for all interfaces is supported just fine by the template.

• N9504 running 9.3.x
• N93180 running 10.3.x

While yes, the command is interface (singular) and not plural, that doesn't negatively affect the function of the template or TextFSM index.

show interface switchport

Generally the templates and parsing is a "biggest return for the investment" so rather than make two really similar templates for related commands, the more detailed one is the one that normally gets created.

The individual interface isn't supported at present, though it is possible to use the same template, but there are issues.

• It's not possible to add a directory with a slash in it so show_interface_eth1/1_switchport is :x: not going to happen.
• This means there's no way to use the project tests to ensure this continues to work.
• There is no other instances like this in the index file.

It's easy enough to add a .* within the index, but should we?

@i-m-d What is your process or use case that the show interface switchport output couldn't be used instead?

If adding support for a specific interface is allowed, I'd also rename files to drop the "s" while I'm at it.

@jmcgill298 @jvanderaa Thoughts before I work up a PR?

🎯 What NX-OS version or versions are you running against?

I have several Nexus models and several versions:

@i-m-d I noticed you didn't provide the information the issue ticket asks for. :thinking: :neutral_face:

I'm fine with just adding (\s+.+?)? into the index

I'm fine with just adding (\s+.+?)? into the index

@jmcgill298 Sounds better than what I had. :face_with_peeking_eye:

This seems to break the normal show interface switchport command when I test. cisco_nxos_show_interfaces_switchport.textfsm, .*, cisco_nxos, sh[[ow]] int[[erfaces]](\s+.+?)?sw[[itchport]]

Chucking a space before or after the pattern (\s+.+?)? helps fix that. Both show interface switchport and show interface eth1/1 switchport function with the below index entry. cisco_nxos_show_interfaces_switchport.textfsm, .*, cisco_nxos, sh[[ow]] int[[erfaces]](\s+.+?)? sw[[itchport]]

That \s+ helps document our intent for a space and other characters before the switchport key word. :grinning:

I'll work up a change that includes renaming to drop the unnecessary "s" from interfaces to align with the other cisco_nexus templates.

[mjbear]

Update: :arrow_right: I'm going to suggest dropping the innermost question mark since the entire group of (\s+.+)? is optional. cisco_nxos_show_interface_switchport.textfsm, .*, cisco_nxos, sh[[ow]] int[[erface]](\s+.+)? sw[[itchport]]
