Cisco 3548-XL Secondary IP

Hi,

I am trying to add a primary and secondary IP to a Vlan using the following command.

Config t
Int vlan41
ip address 10.10.0.19 255.255.248.0
ip address 10.10.0.83 255.255.248.0 secondary


The commands are accepted without any errors.

But when I show the config the primary IP is only listed.

interface VLAN41
 ip address 10.10.0.19 255.255.248.0


Can someone help.

Thank you in advance.

Hi,

If you not enabled ip routing int the switch you not able to give secondary address to VLAN interface.

you need:

conf t
ip routing
Int vlan41
ip address 10.10.0.19 255.255.248.0
ip address 10.10.0.83 255.255.248.0 secondary

Open in new window

A 3548 is a L2 device only, it does not support routing and therefor I don't think it supports  secondary IP addresses.
