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
