FCIP Issues
(The time stamp can be activated under the FCIP interface.)
B-port mode disabled
TCP Connection Information
2 Active TCP connections
Control connection: Local 10.10.10.2:3225, Remote 10.10.11.2:65519
(The above is class F traffic.)
Data connection: Local 10.10.10.2:3225, Remote 10.10.11.2:65521
(This is class 2,3 traffic.)
6 Attempts for active connections, 3 close of connections
TCP Parameters
Path MTU 1500 bytes
Current retransmission timeout is 100 ms <<< Default, adjusted under
Round trip time: Smoothed 10 ms, Variance: 5
(This is the calculated round trip time of the FCIP tunnel. Large round trip times will require increasing
the TCP window size under the FCIP profile.)
Advertized window: Current: 64 KB, Maximum: 64 KB, Scale: 1
(This is the local advertised TCP window size, and the default is 64 KB.)
Peer receive window: Current: 64 KB, Maximum: 64 KB, Scale: 1
(This is the remote endpoint advertised TCP window size.)
Congestion window: Current: 2 KB
(This is the minimum window size used during congestion, and it is not configurable.)
