Chapter 3 Cisco IGX 8400 Series Nodes
IGX Node Configuration
Adding an Interface Shelf
An interface shelf is a non-routing device that drives ATM cells to and from an IGX routing hub in a
tiered network. (An interface shelf is also sometimes referred to as a feeder shelf.) An interface shelf can
be either an IGX or MGX 8850 node configured as an interface shelf, or an MGX 8220 interface shelf.
Because tiered network capability is a purchased option, for an IGX node to serve as an interface shelf,
personnel in the Technical Assistance Center (TAC) must first configure it for that purpose (for
information on contacting TAC, see “Obtaining Technical Assistance” section on page xiv).
To add an interface shelf, use the addshelf command. To delete a feeder shelf, use the delshelf
command. To view conditions on a feeder trunk, use the dspnode command.
Note The addshelf and addtrk commands are mutually exclusive.
IGX/AF is the designation of an IGX node serving as an interface shelf. Display commands such as
dspnw and dspnode display these designations. The dspnode command identifies the hub and feeder
nodes and shows the alarm status. The designation for an MGX 8220 shelf serving as an interface shelf
is AXIS. The designation for an MGX 8850 serving as an interface shelf is AAL5. The designation for
an SES (Service Expansion Shelf) shelf serving as an interface shelf is also AAL5.
The following procedure applies when adding any supported feeder to an IGX routing node. Table 3-1
displays the commands to configure an SES (Service Expansion Shelf) as a feeder to an IGX 8400
routing hub.
Specifying Card Redundancy
You can set up card redundancy by installing two identical front and back card sets, connecting them
with a Y-cable on each paired port, then specifying redundancy with the switch software addyred
command. Redundancy applies to the entire card and is not port or line-specific.
