In Exos, you can issue a “show port xx vlan” to get a short, simple list of vlan’s on a port. Is there a similar way to get a brief list of ports within a vlan (as opposed to “show vlan xx”, where it’s a small block of info at the bottom? I want to see all ports in V90 for example, nothing else. Would be cool with something like “show vlan xx members”.

Thanks!

I did a thing

Perhaps a product enhancement suggestion? “show vlan vxxx members” with a tagged or untagged flag option to further narrow down the list?

Its an ugly solution, but what about “show config vlan | i “ <vlan name> add ports” ?

# show config vlan | i " Default add ports"
configure vlan Default add ports 1:1-7,1:9-15 untagged

Eric,

Not as far as I can tell. The only thing I could suggest is “sh vlan FOO | begin Ports:”, but that still gives you the entire “Flags” legend at the bottom

“grep” probably won’t do what you need - there can be line-breaks in the port list, grep-ing for parentheses would still include the “Flags”, and you can’t double-pipe.

I would guess someone could come up with a python script, but if there’s a better way, I’d be interested as well.

Is there a simple way to see ports in a VLAN, like you can see vlan's on a port?
