% IP addresses may not be configured on L2 links

Unanswered Question


I have 2611-XM. I have a FastEthernet Module connected on it with 16 ports.

Everytime i try to configure the IP address on the FastEthernet , i keep getting this error % IP addresses may not be configured on L2 links".

When i do "show vlan-switch" i do see all the FastEthernet's are under VLAN-1. I do not want these ports to be under VLAN-1. Is there a way i can individually configure the IP addresses on these FastEthernets. I removed the VLAN-'s but still didn't work. Any ideas, help or documentation would be appreciated.

You cannot put an address on the switchports , you must create a layer 3 SVI and then put the ports into that vlan .

No Glenn meant you need to make your interfaces as L3 SVI and then assign an IP address to it.

Do this -->

conf t


no switchport

ip address x.x.x.x x.x.x.x

or if you want the port to be a member of VLAN, do this-->

conf t

int vlan

ip address x.x.x.x x.x.x.x


switchport access vlan

Hello Abhishek,

Actually, i can create a VLAN-40 and assign the Ip address to this VLAN-40. Then under Fas 1/0 i can put 'switchport access vlan 40'.

When i do "sh vlan-switch" because this is 2611-XM. i do see that VLAN's so i created a new VLAN, which is VLAN-40.

But i was just wondering is there a way for me to individually assign the IP addresses on my FastEthernet interfaces, rather then combining them into different VLAN's. I did tried under FastEthernet " no switchport" then try to assign it. But it didn't take it.

Could this be due to the IOS c2600-jz-ms..not sure any help will be apprecaited.
