Configuring Circuits

A circuit on the CSS is a logical entity that maps IP interfaces to a logical port or group of logical ports, for example, a VLAN. Each VLAN circuit requires an IP address. Assigning an IP address to each VLAN circuit allows the CSS to route Ethernet interfaces from VLAN to VLAN. Router Discovery Protocol (RDP) settings can also be configured for each circuit VLAN to advertise the CSS to hosts.

Entering Circuit Configuration Mode

To enter the circuit configuration mode to configure a VLAN, use the circuit command. Enter the specific VLAN in uppercase letters. Do not include a space between VLAN and the VLAN number. For example:

(config)# circuit VLAN7

(config-circuit[VLAN7])#
