000119: .May 17 15:41:47.017 SAST: %MAINBOARD_SFP-3-NOT_IDENTIFIED: Unidentified transceiver module in GigabitEthernet0/1 port.

000125: .May 17 16:00:41.006 SAST: %MAINBOARD_SFP-3-NOT_IDENTIFIED: Unidentified transceiver module in GigabitEthernet0/1 port.

000129: .May 17 16:02:00.005 SAST: %MAINBOARD_SFP-3-NOT_IDENTIFIED: Unidentified transceiver module in GigabitEthernet0/1 port.

 

Router#   sh int gig0/1

GigabitEthernet0/1 is down, line protocol is down

  Hardware is CN Gigabit Ethernet, address is f872.eac3.7e21 (bia f872.eac3.7e21)

  Description: BT DEVICE - AAN-ZA-0001-RTR2 Gig 10/11

  Internet address is 10.248.54.2/28

  MTU 1500 bytes, BW 1000000 Kbit/sec, DLY 10 usec,

     reliability 255/255, txload 1/255, rxload 1/255

  Encapsulation ARPA, loopback not set

SOLUTION :

 

(config)#service internal
(config)#service unsupported-transceiver

 

Router#sh int gig0/1
