Este documento descreve como solucionar problemas de placas de linha que foram desligadas devido a falhas de comunicação nos Cisco Catalyst 6500 Series Switches.
Não existem requisitos específicos para este documento.
As informações neste documento são baseadas nos Cisco Catalyst 6500 Series Switches e não estão limitadas a uma versão de software específica.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
O protocolo de cópia segura (SCP - Secure Copy Protocol) é o protocolo usado para comunicação entre processadores de switch (SPs - Switch Processor) e placas de linha não-DFC (Distributed Forwarding Card) através do EOBC (Ethernet out of band channel) no Catalyst 6500. As falhas de pesquisa SCP ou de manutenção de atividade podem representar problemas de comunicação entre o supervisor e a placa de linha.
Sempre que um módulo for desligado, execute estas verificações:
Verifique os registros para ver se uma falha de pesquisa de 'SCP dnld' ou de manutenção de atividade é o motivo pelo qual o módulo está desligado:
%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)
Este procedimento descreve como solucionar problemas de comunicação entre o supervisor e a placa de linha.

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)
