Description (partial)

Symptom: Traffic is lost for up to 700ms on a port channel failover
with X2 optics.
Conditions: The traffic loss may occur when the active interface on a
port channel is administratively shut down.  Traffic is lost until the far
end detects link down and switches to the backup link.  The loss is highly
variable but rarely exceeds 700ms.  This is only known to occur on 10G links
with X2 optics.
