Hello,
Last week an SFP GLC-SX-MM gave the following errors in the log:
Mar 3 11:34:59: %OSPF-5-ADJCHG: Process 1, Nbr 10.14.254.254 on GigabitEthernet
1/1 from FULL to DOWN, Neighbor Down: Interface down or detached - ctw_check_err
or_bit - on!!!!!!
- ctw_check_error_bit - on!!!!!!
- ctw_check_error_bit - on!!!!!!
Mar 3 12:11:26: %PM_SCP-SP-3-TRANSCEIVER_BAD_EEPROM: Integrity check on transce
iver in LAN port 1/1 failed: bad key
Mar 3 12:21:09: %OSPF-5-ADJCHG: Process 1, Nbr 10.14.254.254 on GigabitEthernet
1/1 from INIT to DOWN, Neighbor Down: Interface down or detached
The first is OSPF i would say. Who knows what the ctw_check_error error is this shows up about 200 times before the next message is the bad key message on the sfp.
I have replaced the SFP and the connection is now back up as a restart and reinsertion of the sfp module did not solve the issue.
I would say the SFP in question is defective, just wondering about the ctw_check_error because i cannot find any information about this.
THanks
Arp
