Cisco 3550-12T IP address

[anand]

Can i set IP address in Cisco 3550-12T in any one of the Gigabit Interface, being a layer 3 switch, it is possible, but when i entered the “ip address 192.168.1.1 255.255.255.252” in “gigabitEthernet 0/1” i get a message “IP addresses may not be configured on L2 links” why is that so? I enabled IP Routing & tried without enabling also, but still i get the same message. Thanks in advance.

Just do no switchport on the interface and then configure the IP. By default all interfaces are L2 interfaces,this command will make them IP capable

Hi Anand,

Though it is a layer 3 switch but default behaviour of ports are layer 2.

To make it layer 3 you have to first give "no switchport" command.

int gig0/1

no switchport

ip address

Try issuing the command: no switchport

Now, try: ip address 192.168.1.1 255.255.255.252
