Problem Description
When autonegotiation is enabled on a connected Catalyst switch port, the 15454-DM-L1-xx.x and 15454-DMP-L1-xx.x will not come up or will not recover after autonegotiation synchronization has been triggered on the link.
Background
After a disconnect between the DataMux and Catalyst switch, such as when extracting the connector, performing a shut/no shut or initial configuration, ethernet traffic will not come up on a Catalyst client interface with autonegotiation enabled.
Problem Symptoms
Link is "down/down" on the GE interface even if Optical Power values are within the expected range.
Workaround/Solution
If the problem occurs, disable autonegotiation on the connected Catalyst switch port.
For customers using Catalyst Release 6.3(4) or later, a command has been introduced to extend the autonegotiation sync timer on the Catalyst port. It is recommended that the following syntax be used to properly configure autonegotiation on the Catalyst:
sync-restart-delay 10000
Please refer to the Catalyst 6000 Family Command Reference, Release 6.3, for command usage information.
