VLAN problems on 878

Unanswered Question
Jun 16th, 2008

Hi all,

I need a bit of help getting a second vlan on my 878. I'm pretty sure it can be done, as we have another 878 with it working.

I can't add a vlan to the vlan database:

878-A#vlan 2

Vlan can not be added. Maximum number of 1 vlan(s) in the database.

878-A# sh vlans

No Virtual LANs configured.

878-A#sh run int vlan 2

!

interface Vlan2

description WAN OUTSIDE interface

ip address x.x.x.x 255.255.255.248

878-A#sh int vlan 2

Vlan2 is up, line protocol is down

Here's it working on another 878, even though it also shows no vlans:

878-B#sh vlans

No Virtual LANs configured.

878-B#sh int vlan2

interface Vlan2

description WAN OUTSIDE interface

ip address x.x.x.x 255.255.255.248

878-B#sh int fa3

interface FastEthernet3

switchport access vlan 2

duplex full

speed 100

878-B#sh int vlan 2

Vlan2 is up, line protocol is up

Here's their versions:

878-A#sh ver

Cisco IOS Software, C870 Software (C870-ADVSECURITYK9-M), Version 12.4(4)T7, RELEASE SOFTWARE (fc1)

878-B#sh ver

Cisco IOS Software, C870 Software (C870-ADVIPSERVICESK9-M), Version 12.4(4)T8, RELEASE SOFTWARE (fc3)

Any ideas??? I'm really desperate to get this working!

Many thanks,

J

I have this problem too.

Hi, you need advanced ip service for VLAn on the 870 series, you router B has it hence it works.

Hope this helps, please rate post if it does!
