Cisco Cisco 12000 Series 4-Port OC-12c STM-4c ATM Line Card Guía Para Resolver Problemas

Troubleshoot communication between the supervisor and the line card in question.

• 

Check the logs in order to see if an 'SCP dnld' or keep−alive polling failure is the reason that the module is
powered down:

%C6KPWR−SP−4−DISABLED: power to module in slot 2 set off (Module Failed SCP dnld)

%C6KPWR−SP−4−DISABLED: power to module in slot 2 set off (Module not responding to 

   Keep Alive polling)

This procedure describes how to troubleshoot the communication between the supervisor and the line card.

Check the global SCP counters from the SP−side for any incrementing errors.

6500#remote command switch show scp counters

6500−sp# 

received packets            = 586786 

transmitted packets         = 584442 

retransmitted packets       = 13        (increasing re−transmissions indicate 

                                         congested EOBC) 

loop back packets           = 0 

transmit failures           = 0         (increasing transmit failures indicate 

                                         congested/stuck EOBC) 

recv pkts not for me        = 0 

recv pkts to dead process   = 0 

recv pkts not enqueuable    = 0         (increasing counters indicate lack of 

                                         EOBC buffers) 

response has wrong opcode   = 0 

response has wrong seqnum   = 0

response is not an ack      = 0 

response is too big         = 0

1. 

Check the per−module SCP receive/transmit counters, and check for incrementing SCP retries.

2. 

Check SCP pings from the supervisor to the module in question.

6500#remote command switch test scp ping 3

6500−sp# 

pinging addr 5(0x5) 

assigned sap 0x11 

addr 5(0x5) is alive       (Communication between the supervisor and line 

                            card is fine)
