Expandin Subnet on Cisco 3550 Layer 3 Switch

I have a Cisco model 3550 layer 3 switch. I am presently only using the

default VLAN1. I have addressed the vlan1 interface with the IP, > I am trying to expand this subnet to include another > 255 IP's. > > I am dong this by using the network address, which would > include all 230.x and 231.x addresses. The only change I made to the > 3550 is to change the existing mask on the VLAN1 interface to > using the same IP address stated above.
