This occured while stopping, then re-starting the STBY CE. Following this, the STBY CE was dying.

Hello Hong,

eth3 interfaces on both knicks and spurs are not configured correctly.

We can see that IP packets were dropped on eth3:

knicks

I ran ifconfig eth3 txqueuelen 1000 on both.

But the main issue here is that eth3 is 100 Mbps Half Duplex where eth4 is 1000 Mbps Full Duplex:

> grep "Half Duplex" /var/log/messages

Jul  6 14:18:54 spurs kernel: e1000: eth3: e1000_watchdog_task: NIC Link is Up 100 Mbps Half Duplex
Jul  6 14:34:44 knicks kernel: e1000: eth3: e1000_watchdog_task: NIC Link is Up 100 Mbps Half Duplex

This must be fixed.

Eric.
