Changing configuration (enable/disable/auto-negotiation) on copper SFPs on 10000-series appliance might cause an internal bus to hang. Symptoms are bcm56xxd process restarts, and the interfaces may show as unknown.
The bcm56xxd process restarts, and the interfaces may show as unknown.
Only copper SFPs OPT-0015 on 10000-series appliances exhibit this problem.
To work around this issue, follow these steps: 1) Force the system offline. 2) Reboot the system. 3) Release the system's offline status.
The bcm56xxd daemon detects a bus problem and resets the bus to recover communications with SFP transceivers.
