Displaying the ARP age value
Reconfiguring the router ID (optional)
If you want to change the router ID setting, do the following:
Procedure
1. Go to the global config context; the CLI prompt appears similar to the following:
2. switch(config)#_
3. If OSPF is not enabled, go to 4; if OSPF is enabled, use no router ospf to disable OSPF operation.
4. Use ip router-id ip-addr to specify a new router ID. (This IP address must be unique in the routing
switch configuration.)
5. If you disabled OSPF operation in 3, use router ospf to re-enable OSPF operation.
For more information on the router ID, see
IP global parameters for routing switches on page 146 and
Changing the router ID on page 150.
Changing the router ID
Syntax:
ip router-id ip-addr
The ip-addr can be any valid, unique IP address.
switch(config)# ip router-id 209.157.22.26
NOTE: You can specify an IP address used for an interface on the routing switch, but do not specify
an IP address in use by another device.
Enabling proxy ARP
Proxy ARP is disabled by default on routing switches. Enter the following commands from the VLAN context level
in the CLI to enable proxy ARP:
switch(config)# vlan 1
switch(vlan-1)# ip proxy-arp
