Problem Description

Network Processor Module (NPM) bootcode does not load properly until the NPM is physically powered down and then powered back up. The power cycle may be accomplished by either reseating the NPM or turning the IGX-8400 node off and then back on.

Problem Symptoms

After burning the NPM firmware to the NPM and executing switchcc, the network operator will observe the following display using the dspcd 1|2 command:

igxnode        TRM   StrataCom       IGX 8420  9.1.10    May  21 1999 19:35 PDT
Detailed Card Display for NPM in slot 1
Status:          Standby
Revision:        BVP
Serial Number:   586291
RAM Id:          9.1.10
ROM Id:          9.1.10
BOOT Id:         R.B.R
BRAM Id:         9.1.10
RAM Size:        32 Meg
BRAM Size:       1024 K
Flash EEPROMs:   Installed - 4.00 Meg
Last Command: dspcd 1

Note that after NPM in slot 1 reaches standby, Revision is still "BVP" instead of "BVR".

Similarly, the dspcds command may be used to observe the bootcode version:

Background

NPM bootcode upgrade may be required as IGX-8400 networks are upgraded to later versions of software. It is important to upgrade NPM bootcode properly in order to maximize IGX-8400 stability and performance.

Workaround/Solution

Solution

The NPM should be "downed" by using dncd slot_number command first. Then, the NPM should be physically reseated. This defect has Cisco bug ID CSCdm21875. If you are a registered CCO user and you have logged in, you can view the bug details.

A second, less desirable method is to power cycle the IGX-8400 node.

After reseating the NPM, use the dspcd 1|2 or dspcds command to verify that the proper version of bootcode is loaded:
