Hi,

I have a 16 series cisco router.these are the interfaces available.
Router16#show ip interface brief
Interface IP-Address OK? Method Status Protocol

Ethernet0 192.168.10.131 YES manual up down

Serial0 200.20.20.2 YES NVRAM down down

01:14:30: %QUICC_ETHER-1-LOSTCARR: Unit 0, lost carrier. Transceiver problem?
01:15:30: %QUICC_ETHER-1-LOSTCARR: Unit 0, lost carrier. Transceiver problem?

There is an ethernet port which is not being listed by this command and the error you see just above is continuously being displays.Is this due to the corrupted interface ? Please advise
