Displaying Interface Capabilities

Before configuring a Generation 2 or Generation 3 interface, you can use the show interface capabilities command to display detailed information about the capabilities of the interface.

This example shows the capabilities of a Generation 2 Fibre Channel interface:

switch# show interface fc 9/1 capabilities
Min Speed is 1 Gbps
Max Speed is 4 Gbps
FC-PH Version (high, low)	(0,6)
Receive data field size (max/min)	(2112/256) bytes
Transmit data field size (max/min)	(2112/128)	bytes
Classes of Service supported are	Class 2, Class 3, Class F
Class 2 sequential delivery	supported
Class 3 sequential delivery	supported
Hold time (max/min)	(100/1) micro sec
BB state change notification	supported
Maximum BB state change notifications	14
Rate Mode change	supported
Rate Mode Capabilities	Shared	Dedicated
Receive BB Credit modification supported	yes	yes
FX mode Receive BB Credit (min/max/default)	(1/16/16)	(1/250/16)
ISL mode Receive BB Credit (min/max/default)	--	(2/250/250)
Performance buffer modification supported	no	no
Out of Service capable	yes
Beacon mode configurable	yes

This example shows the capabilities of an interface on the 48-port 8-Gbps Fibre Channel switching module:

	switch# show interface fc 4/1 capabilities
	Min Speed is 1 Gbps
	Max Speed is 8 Gbps
	FC-PH Version (high, low)	(0,6)
	Receive data field size (max/min)	(2112/256) bytes
	Transmit data field size (max/min)	(2112/128) bytes
	Classes of Service supported are	Class 2, Class 3, Class F
	Class 2 sequential delivery	supported
	Class 3 sequential delivery	supported
	Hold time (max/min)	(100000/1) micro sec
