Solved: VLANS

jim · ‎05-11-2007

Im setting up a secondary core switch with a pair of 6513's and I have a problem.

Three of the 10 vlans I have created show up as down down and for the life of me I cant figure out why.

Im running Version 12.2(18)SXD7a on both switches.

Vlan1 172.16.255.254 YES NVRAM up up

Vlan3 172.19.240.254 YES NVRAM up up

Vlan4 unassigned YES NVRAM administratively down down

Vlan8 10.3.96.254 YES NVRAM down down

Vlan10 10.0.20.254 YES manual down down

Vlan30 172.16.30.254 YES NVRAM down down

Vlan109 unassigned YES unset administratively down down

Vlan160 172.16.0.254 YES NVRAM up up

Vlan610 172.16.10.254 YES NVRAM up up

Vlan611 172.16.11.254 YES NVRAM up up

Vlan612 172.16.12.254 YES NVRAM up up

Hi Friend,

Do you have any physical port assigned to vlan 8,10,30? Or do you have a trunk port configured which allow these vlans.

Any of the condition should be necessary to mae the interface vlan up and up.

Im refering to vlans 8,10,30

jim · ‎05-11-2007

Is there a quick way to delete all vlans in a database and start from scratch?

I dont have physical ports assigned to several of those vlans yet but they came up.

ankbhasi · ‎05-11-2007

Hi Jim,

But then you must be having a trunk port configured which must be allowing those vlans.

Regards,

Ankur

Anyone?

Jon Marshall · ‎05-11-2007

Jim

Could you post the output of a "sh interface trunk" please.

Jon

jim · ‎05-11-2007

Actually the output is empty since I have the two trunked interfaces down at the moment. You both might be right then.. I may have to bring those trunks UP to get the vlans to come up. It just suprised me that my other 6 vlans come up without being assigned to an interface yet.

I did make sure to use the trunkport vlan allow all command on both trunks g7/1, g7/2 to the primary 6513.
