configure interface vlan on switch 3524 XL

Hi all,

I have an old switch C3524 running image "C3500XL-c3h2s-mz-120.5.2-xu". I had successfully created vlan 120 but when I config "interface vlan 120" as follows:

swicth # conf t

switch(config-subif)#interface vlan 120

switch(config-subif)#ip address 172.10.10.1 255.255.255.0

switch(config-subif)#no shut

 

then show run does not see this interface. Show vlan indicates vlan 120 is active.

Please help. thank you.

3500XL is a layer 2 switch

3500XL is a layer 2 switch.

only one vlan can be active at a time.

shut down vlan 1 then you should be able to bring up vlan 120.

 

hope this helps,

please rate helpful posts.

thanks

after I remove the vlan 120 from one fastethernet interface, show run now sees the interface vlan 120 but in shutdown mode. Trying to do no shut but not help. Please advise.

you're right. I just shut

you're right. I just shut down interface vlan 10 (interface vlan 1 is down already) then interface vlan 120 comes up. Question is: if I need to configure several ports: some in vlan 10 and some in vlan 120 then should I have interface vlan 10 up too ?

Thank you very much.

Since it's not a layer 3

Since it's not a layer 3 device, svi's are not needed for each vlan.  Create the vlans on the switch and trunk them to a layer 3 device, which will do your routing.
