Cisco 2950 switch management IP change issue

Hi All,

I am planning to change the management IP (VLAN 5) to one of my Cisco 2950 switch, Here I am creating a new VLAN101 and assign new IP

When I am doing this VLAN 2 is going admin down.

Can somebody help me the reason behind, Is It switch limitation or am I doing any mistake.

Regards

Suresh

A layer2-switch like yours can only have one active IP-address for management. So when you add a new VLAN-interface with an IP-address the old int goes down. Works as designed. If it would be a layer3-switch, you could have multiple active VLAN-interfaces with IP-addresses configured.
