Adding an Interface Shelf
An interface shelf is a non-routing device that drives ATM cells to and from a BPX or IGX routing hub
in a tiered network. (An interface shelf is also sometimes referred to as a feeder shelf.) An interface
shelf can be:
•
an IGX node configured as an interface shelf
• an MGX 8850 node configured as an interface shelf
• an MGX 8220 interface shelf
•
an MGX 8800 interface shelf
• a Service Expanions Shelf (SES) with PNNI
For instructions on installing a Service Expansion Shelf in a BPX 8620 rack and initially powering up,
see Cisco Service Expansion Shelf (SES) Hardware Installation Guide. To configure an SES PNNI for
a BPX 8620, see the Cisco SES PNNI Controller Software Configuration Guide.
Because tiered network capability is a purchased option, personnel in the Technical Assistance Center
(TAC) must first configure a node to serve as an interface shelf. Then you must use the cnftrk command
to configure an interface shelf to use STI cell headers and BPX Addressing Mode (BAM).
Before you can add an MGX 8220 shelf to a tiered network, the shelf must be an available resource in
the network. (For instructions on how to bring up an MGX 8220 shelf, see the MGX 8220
documentation.)
To add an interface shelf, use addshelf. See Figure3-7 for an illustration of the command sequence for
setting up an interface shelf. (Note that addshelf and addtrk are mutually exclusive commands.)
To delete a feeder shelf, use delshelf.
To view conditions on a feeder trunk, use dspnode.
Table 18-3 show designations for various devices that can be used as interface shelves. To display these
designations, use the display commands dspnw and dspnode. The dspnode command identifies the hub
and feeder nodes and shows the alarm status.
