Be sure that you understand the potential effects of router port-based and VLAN-based routing on your network. See the Implementation Guide for the CoreBuilder 3500 and for the CoreBuilder 9000 for detailed information about IP interfaces and VLANs.

Page 407: Ip Interface Modify
Important Consideration 3900 9300 On the CoreBuilder 3500, you cannot modify the port number (router port-based routing) after it has been defined because of the associated virtual LAN (VLAN); you must remove the interface and then redefine it.
Page 408: Ip Interface Remove
Before you remove the interface, remove any static entries in the routing table or the Address Resolution Protocol (ARP) cache. On the CoreBuilder 3500, if you remove a router port-based IP interface, the system removes the virtual LAN (VLAN) that is associated with it as well.
