Configuring a Circuit IP Address
To assign an IP address to a circuit, use the ip address command. Enter the IP
address and a subnet mask in CIDR bit-count notation or a mask in dotted-decimal
notation. The subnet mask range is 8 to 31.
For example, to configure an IP address and subnet mask for VLAN7, enter:
(config-circuit[VLAN7])# ip address 172.16.6.58/8
When you specify an IP address, the mode changes to the specific
circuit-ip-VLAN-IP address as shown:
(config-circuit-ip[VLAN7-172.16.6.58])#
Note The CSS automatically sends a gratuitous ARP for the IP interface address when
you assign an IP address to a circuit. The gratuitous ARP informs all network
nodes about ARP mapping. The CSS transmits one ARP request packet and one
ARP reply packet for every gratuitous ARP invocation.
To remove a local IP address from a circuit, enter the following command from
circuit mode:
(config-circuit[VLAN7])# no ip address
Configuring a Circuit-IP Broadcast Address
To change the broadcast address associated with a circuit, use the broadcast
command. If you leave the broadcast address at zero, the all-ones host is used for
numbered interfaces.
The default broadcast address is an all-ones host address (for example, IP address
172.16.6.58/24 has a broadcast address of 172.16.6.58/255). This command is
available in IP configuration mode.
For example, to change the broadcast address on circuit VLAN7, enter:
(config-circuit-ip[VLAN7-172.16.6.58])# broadcast 0.0.0.0
To reset the broadcast IP address to the default all-ones host address, enter:
(config-circuit[VLAN7-172.16.6.58])# no broadcast
