Adding an Interface Shelf
Displaying or Printing Trunk Configurations
You can display the network trunk configuration on the screen or print it on the printer in a one-step
process by using any one of the following commands listed in Table 18-3.
Adding an Interface Shelf
An interface shelf is a nonrouting 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 8220, MGX 8230, and MGX 8250 interface shelf.
• a Service Expansions Shelf (SES) with PNNI.
For instructions on installing a Service Expansion Shelf in a BPX 8620 rack and initially powering up,
refer to the
Cisco Service Expansion Shelf (SES) Hardware Installation Guide . To configure an SES
PNNI for a BPX 8620, refer to 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 . For an illustration of the command sequence for to set up an
interface shelf, see Figure 17-5.
Note The addshelf and addtrk commands are mutually exclusive.
To delete a feeder shelf, use the delshelf command.
To view conditions on a feeder trunk, use the dspnode command.
The designations for various devices that can be used as interface shelves are listed in Table 18-4. 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.
