NX-OS 'show" command filters - CDP Neighbors

[Marcin Zgola]

I have a problem with NX-OS and i am trying to initiate the following command to filter output of "show cdp nei det"

this is how i would done on 6500

show cdp nei det | grep Device |IPv4 Add|Cisco IOS Softw

I need this to work on NX-OS.. I noticed lots of features after "|" is there a nice document out there to help me understand and i assume do things better.

thanks

The configuration guide has a pretty extensive section on the use of regular expressions in the NX-OS cli.

Reference

For your particular example, the string:

show cdp nei det | egrep 'Device |IPv4 Add|Cisco IOS Softw'

...would work. Note that it excludes software for neighbors not running IOS (e.g. NX-OS etc.).

I use following command to find out which spanning tree has large TCN on N9K, similar should work on NXOS with filter string include space.

show spanning-tree detail | in 'executing|Number of topology'
