Description

This article explains why IQ2 and IQ2E physical interface cards (PICs) reboot when the traffic manager mode is changed. The PIC is changing from default value of ingress-and-egress to egress-only . This reboot is expected behavior. Non-IQ PICs do not support ingress scheduling, so they will not reboot.

Symptoms

IQ2 and IQ2E PICs will reboot when traffic manager mode is changed under the following hierarchy.

The following log messages will be seen:

%DAEMON-4-CHASSISD_CONFIG_WARNING: pic_should_bounce: Traffic manager mode is not valid for this PIC, FPC 0 PIC 0
%DAEMON-4-CHASSISD_CONFIG_WARNING: pic_should_bounce: Traffic manager mode is not valid for this PIC, FPC 0 PIC 1

%DAEMON-4-CHASSISD_CONFIG_WARNING: pic_should_bounce: Traffic manager mode is not valid for this PIC, FPC 0 PIC

NON-IQ2 PIC will not reboot.

Solution

A traffic-manager mode change from the default value of ingress-and-egress to egress-only will cause the PIC to reboot.

Non-IQ PICs do not support ingress scheduling so they will not reboot.

A traffic-manager mode change will cause the PIC to bounce. It is changing from default value of ingress-and-egress to egress-only. This is expected behavior.

Non-IQ PICs do not support ingress scheduling so they will not reboot.
