2924XL multiple vlan interfaces

Unanswered Question
May 12th, 2008


I have a 2924XL switch with IOS: 12.0(5)WC9a. It is not letting em make 2Vlan interfaces active at a a timwe. If inter Vla1 active then, other Vlan have to 'shudown'. Is this limitation of switch or IOS..?

Please suggest.

Thank you


I have this problem too.

For a layer 2 switch such as the 2924 this is normal behavior. A layer 2 switch can have only a single VLAN interface active at a time.

I believe that perhaps you have confused having multiple VLANs active with having multiple VLAN interfaces active. The layer 2 switch can have multiple active VLANs but not multiple active VLAN interfaces.

Remember that a VLAN is a layer 2 entity and you can have multiple layer 2 VLANs be active on the switch. But a VLAN interface is a layer 3 entity which is configured on the layer 2 switch for management. And there can be only a single VLAN interface active at a time on a layer 2 switch.

Thank you Rick..Iam not confused.. I am looking for some basic switch with 2 interface Vlans active at a time (for basic directly connected routing).What is the minimum switch/IOS you recommend.

Thank you
