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

Eric_Burke — Tue, 07 Apr 2020 19:54:26 GMT

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!

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.

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

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

If you would like a feature request opened for this, please open a case with GTAC and we can do so.

Thanks

This is quite easy but verbose:

* X440G2-12p.8 # show ports vlan port-number
Untagged
Port /Tagged VLAN Name(s)
-------- -------- ------------------------------------------------------------
1 Untagged Default
2 Untagged Default
3 Untagged Default
4 Untagged Default
5 Untagged Default
Tagged VLAN10
6 Untagged Default
7 Untagged Default
8 Untagged Default
9 Untagged Default
10 Untagged Default
11 Untagged Default
Tagged VLAN10
12 Untagged Default
13 Untagged Default
14 Untagged Default
15 Untagged Default
16 Untagged Default

I’m still waiting for a portation of EOS command

show vlan portinfo vlan xxx

that would solve your question…

If anyone is familiar with python it should be possible to modify following script for this.

I did a thing

#!/usr/bin/env python
'''
Shows ports in a vlan

Tested on EXOS 22.6.1.4

Execute with: 
 - run script vlanports.py
 or
 - Make an alias: alias vlanport "run script vlanports.py"
'''

import re
import sys

exsh.clicmd('disable clipaging', False)

# Input the tag or complete name of the vlan.
if len(sys.argv) < 2: 
 input_tag = raw_input("Vlan: ")
else:
 input_tag = sys.argv[1]

# Get vlan name
vlan_name = exsh.clicmd('show vlan {} | inc name'.format(input_tag), True)
if not vlan_name:
 print 'Error: No <vlan_list> found with ID {}'.format(input_tag)
 exit()
vlan_name = vlan_name.split()[4] 

# Extract vlan secction of the configuration
config_lines = exsh.clicmd('show configuration vlan', True).splitlines()


# Find the first line that matches "configure vlan <vlan_name> add ports"
regex = re.compile('configure vlan {} add ports'.format(vlan_name), re.IGNORECASE)


for i, line in enumerate(config_lines):
 if regex.match(line):
 line_field = line.split()
 print 'Ports {tag}: {ports}'.format(tag = line_field[-1], ports = line_field[5])

 # If there are tagged and untagged ports configured in the vlan, the next line in the configuration has them
 if regex.match(config_lines[i+1]):
 line_field = config_lines[i+1].split()
 print 'Ports {tag}: {ports}'.format(tag = line_field[-1], ports = line_field[5])
 exit()

print 'No ports in this vlan'
