Verifying Interface Buffer Configuration

Verifying Interface Buffer Configuration
This example shows which of the interfaces on a specified module are in R_RDY flow-control mode:
switch# show flow-control r_rdy module 3
fc3/17
fc3/18
This example shows how to verify the buffer-to-buffer credit information for all interfaces:
sswitch# show interface bbcredit
fc2/1 is down (SFP not present)
.
.
.
fc2/17 is trunking
Transmit B2B Credit is 255
Receive B2B Credit is 12
Receive B2B Credit performance buffers is 375
12 receive B2B credit remaining
255 transmit B2B credit remaining
fc2/21 is down (Link failure or not-connected)
.
.
.
fc2/31 is up
Transmit B2B Credit is 0
Receive B2B Credit is 12
Receive B2B Credit performance buffers is 48
12 receive B2B credit remaining
0 transmit B2B credit remaining
This example shows how to verify buffer-to-buffer credit information for a specific Fibre Channel interface:
switch# show interface fc2/31 bbcredit
fc2/31 is up
Transmit B2B Credit is 0
Receive B2B Credit is 12
Receive B2B Credit performance buffers is 48
12 receive B2B credit remaining
0 transmit B2B credit remaining
This example shows how to verify the type of buffers and data field size a port supports:
switch# show interface fc1/1 capabilities
fc1/1
Min Speed is 2 Gbps
Max Speed is 16 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
BB state change notification supported
