Easy way to tell if VLAN is in use on 1638p?

Hello all, 

I've recently taken over a Network Admin job at a business that utilizes all 1638p's, and I've never worked with Adtrans before now. In taking over, one of my duties is to get the NAC up and running. To do that, I need to know what VLANs are in use or not. There are at least 3 VLANs created on all the switches, but how do I determine if there is actually traffic moving across them? "show switchports vlan" gives me a list of ports that have VLANs enabled, but I can't find any command to allow me to watch traffic coming over in realtime. 
I looked into setting up "ip flow" for integrated traffic monitoring found on the AOS Command Guide, but that seems to be in Release 16.1 and the 1638p can't get updated past 13.12.1 (ours are on 13.5.3).

 

Any help would be greatly appreciated. 

Thanks!

Re: Easy way to tell if VLAN is in use on 1638p?

To see what is on a VLAN - 

NV1638P# sh mac add

Will show you all the devices on the switch and the VLAN they are using.


To see traffic on a VLAN - 

NV1638P# sh int vlan 1 realtime

vlan 1 is UP
Hardware address is 00:A0:C8:7B:F5:33
vlan 1 Ip address is 10.10.10.1, netmask is 255.255.255.0
IP MTU is 1500 bytes
BW is 100000 Kbit
ARP type: ARPA; ARP timeout is 20 minutes
IP route-cache express: enabled
Last clearing of "show interface" counters: never

  • Firmware releases without a Letter in front of them are very old.

  • The switches do not support "ip flow"

Hope this helps.
