Unable to create VLAN

Hi. I am trying to create a VLAN in my 6509 with MSFC2 switch but unable. What am I doing wrong? I have already created the VLAN interface on the router side. Thanks.

Here is the error message.

Campus_Catalyst> (enable) set vlan 700 type ethernet state active name 76.224_Segment

VTP advertisements transmitting temporarily stopped,

and will resume after the command finishes.

Duplicate SAID value 100700

Vlan configuration failed (19)

Campus_Catalyst> (enable)

Re: Unable to create VLAN

Just type " set vlan 700" and make sure the switch is not in vtp client mode

Re: Unable to create VLAN

I think when you created vlan, instead of using just " vlan num" you type the whole command or or just copied or paste the config from somewhere that why your vlan 650 said id 100700 which should be for vlan 700.

Delete vlan 650 and then create vlan 700 and then create 650 or just the definite said value for the vlan 700..

ch-6500-2b> (enable) set vlan 650 name cisco1 type ethernet mtu 1500 said 100700

Vlan 650 configuration successful

ch-6500-2b> (enable) set vlan 650 name cisco1 type ethernet mtu 1500 said 100700

ch-6500-2b> (enable) set vlan 700

Duplicate SAID value 100700

Vlan configuration failed (19)

ch-6500-2b> (enable) clear vlan 650

This command will de-activate all ports on vlan 650

Do you want to continue(y/n) [n]?y

Vlan 650 deleted

ch-6500-2b> (enable) set vlan 700

Vlan 700 configuration successful

ch-6500-2b> (enable) set vlan 650

Vlan 650 configuration successful

ch-6500-2b> (enable)

Re: Unable to create VLAN

you have already the SAID 1000700

see your output:

set vlan 650 name 76.192_Seg type ethernet mtu 1500 said 100700 state active

1. you have to delete vlan 650 if possible

2. create vlan 650 with SAID 1000650

3. create vlan 700 with SAID 1000700
