Hi All,
Got a strange one. I have two CCR 1072's back to back with a short is
run (1km or so) of single mode with two 10G SFP+ single mode. The SFP's
and run has been previously used and again tested with Cisco equipment
without fault. I have also used the same type of SFP+ with CCR1072's
without fault. But except for this one setup.
The problem is after a random period of time (minutes to hours) one of
the CCR's stop's responding to IP. You cant Ping the CCR or connect to
it locally. Console works and says all is fine but no bidirectional
traffic over the interface. The exception to this is that CDP still
seems to be working as you can see the broadcasts from the CCR on a dump
at the other end of the link. You can also clear the arp cache at the
other end and ping and the mac is re-learning indicating that something
is still happening. The only fix appears to be a reboot. When the unit
starts behaving normally again for a time. If you set the watchdog it
happy reboots the CCR fixing the problem also.
Tried 6.33.3 and also the latest RC no luck. My next move is to replace
the hardware. But it's a very odd hardware fault has anyone else seen
anything like this.
Matt.
