3.4.1Ethernet Port Cannot Be Connected

If the Ethernet port has possibly caused the communication failure, check for the NIF [IP8800/S6700] [IP8800/ S6600] [IP8800/S6300] and port statuses as follows.

(1)Checking NIF status [IP8800/S6700] [IP8800/S6600] [IP8800/S6300]

1.Checking log

For the log, see the manual "Message Log Reference."

2.Isolating the problem according to the NIF status.

Check the NIF status by using the show interfaces command, and isolate the problem according to the table below.

Table 3-6: Check and Action for NIF Status
