To configure the maximum jitter value, follow these steps:
Command
Step 1
switch(config-profile)# no tcp max-jitter
switch(config-profile)# tcp max-jitter
switch(config-profile)# tcp max-jitter 300
switch(config-profile)# no tcp max-jitter 2500
Buffer Size
You can define the required additional buffering—beyond the normal send window size —that TCP
allows before flow controlling the switch's egress path for the FCIP interface. The default FCIP buffer
size is 0 KB.
Use the default if the FCIP traffic is passing through a high throughput WAN link. If you have a
Note
mismatch in speed between the Fibre Channel link and the WAN link, then time stamp errors occur in
the DMA bridge. In such a situation, you can avoid time stamp errors by increasing the buffer size.
To set the buffer size, follow these steps:
Command
Step 1
switch(config-profile)# tcp
send-buffer-size 5000
switch(config-profile)# no tcp
send-buffer-size 5000

Displaying FCIP Profile Configuration Information

Use the show fcip profile command to display FCIP profile configuration information.
switch# show fcip profile 7
FCIP Profile 7
OL-18084-01, Cisco MDS NX-OS Release 4.x
Internet Address is 47.1.1.2 (interface GigabitEthernet4/7)
Listen Port is 3225
TCP parameters
SACK is disabled
PMTU discovery is enabled, reset timeout is 3600 sec
Keep alive is 60 sec
Minimum retransmission timeout is 300 ms
Maximum number of re-transmissions is 4
Send buffer size is 0 KB
Maximum allowed bandwidth is 1000000 kbps
Minimum available bandwidth is 15000 kbps
Estimated round trip time is 1000 usec
Purpose
Disables delay jitter estimation.
Enables the delay jitter feature and sets the time
to its factory default.
Changes the time to 300 microseconds. The
valid range is from 0 to 10000 microseconds.
Leaves the delay jitter feature in an enabled
state but changes the time to its factory default
(1000 microseconds for FCIP interfaces).
Purpose
Configure the advertised buffer size to 5000 KB. The valid
range is from 0 to 16384 KB.
Reverts the switch to its factory default. The default is 0 KB.
