Interface FCIP Misconfiguration Examples
The following example shows the “peer-info” IP address of the remote end-point is missing. The debug
output is from the IPS module.
Module-2# debug ips fcip fsm port 1
module-2# Mar 14 21:37:05 port1: 38:FCIP21: SUP-> Set Port mode 1
Mar 14 21:37:05 port1: 39:FCIP21: SUP-> Port VSAN (1) already set to same value
Mar 14 21:37:05 port1: 40:FCIP21: SUP-> Trunk mode (1) already set to same value
Mar 14 21:37:05 port1: 41:FCIP21: SUP-> Enable tunnel ADMIN UP
Mar 14 21:37:05 port1: 42:FCIP21: Try to Bring UP the Tunnel
Mar 14 21:37:05 port1: 43:FCIP21: Bring up tunnel Failed, peer-ip not set
(The peer IP address is not set.)
MDS2# show int fcip 21
fcip21 is down (Link failure or not-connected)
Hardware is GigabitEthernet
Port WWN is 20:42:00:0b:5f:d5:9f:c0
Admin port mode is auto, trunk mode is on
vsan is 1
