Removing an
Interface
You may want to remove an interface if you no longer route on the ports
associated with the interface.
To remove an IP interface definition:
1 From the top level of the Administration Console, enter:
ip interface remove
2 Enter the slot of the switching module from which you want to remove an
interface.
3 Enter the index number(s) of the interface(s) you want to remove.
Administering
Routes
Each switching module maintains a table of routes to other IP networks,
subnets, and hosts. You can either make static entries in this table using the
Administration Console or configure switching modules to use RIP to
exchange routing information automatically.
Each routing table entry contains the following information:
■ Destination IP Address and Subnet Mask
These elements define the address of the destination network, subnet, or
host. A route matches a given IP address if the bits in the IP address
corresponding to the bits set in the route subnet mask match the route
destination address. When forwarding a packet, if the switching module
finds more than one routing table entry matching an address (for example,
a route to the destination network and a route to the specific subnet within
that network), it will use the most specific route (that is, the route with the
most bits set in its subnet mask).
■ Routing Metric
This metric specifies the number of networks or subnets that a packet must
pass through to reach its destination. The switching module includes the
metric in its RIP updates to allow other routers to compare routing
information received from different sources.
■ Gateway IP Address
This address tells the router how to forward packets whose destination
address matches the route’s IP address and subnet mask. The switching
module forwards such packets to the indicated gateway.
