This example shows how to verify the operational receive data field size for a port:
switch# show interface fc 4/1
fc4/1 is down (SFP not present)
Hardware is Fibre Channel
Port WWN is 20:c1:8c:60:4f:c9:53:00
Admin port mode is auto, trunk mode is on
snmp link state traps are enabled
Port vsan is 1
Receive data field Size is 2112
Beacon is turned off
Logical type is Unknown(0)
5 minutes input rate 0 bits/sec,0 bytes/sec, 0 frames/sec
5 minutes output rate 0 bits/sec,0 bytes/sec, 0 frames/sec
4 frames input,304 bytes
0 discards,0 errors
0 invalid CRC/FCS,0 unknown class
0 too long,0 too short
4 frames output,304 bytes
0 discards,0 errors
0 input OLS,0 LRR,0 NOS,0 loop inits
0 output OLS,0 LRR, 0 NOS, 0 loop inits
Last clearing of "show interface" counters : never
This example shows how to verify credit mode and credit allocation for an ISL:
