sets the XOFF and XON limits for 10G ports.
For

Changing the total buffer limits
This section describes how to change the total buffer limits described in
About XON and XOFF
thresholds
on page 68. You can change the limits for all 1G ports and for all 10G ports.
To change the total buffer limit for all 1G ports, enter a command such as the following.
device(config)# symmetric-flow-control set 1 buffers 320
Total buffers modified, 1G: 320, 10G: 128
To change the total buffer limit for all 10G ports, enter a command such as the following.
device(config)# symmetric-flow-control set 2 buffers 128
Total buffers modified, 1G: 320, 10G: 128

buffers
value
symmetric-flow-control set 1 buffers value
sets the total buffer limits for 1G ports. The default value is
272. You can specify a number from 64 - 320.
symmetric-flow-control set 2 buffers
value sets the total buffer limits for 10G ports. The default value is
416. You can specify a number from 64 - 1632.
Use the
show symmetric
command to view the default or configured total buffer limits. Refer to
Displaying symmetric flow control status
on page 70.
Displaying symmetric flow control status
The
show symmetric-flow-control
command displays the status of symmetric flow control as well as
the default or configured total buffer limits and XON and XOFF thresholds.
device(config)# show symmetric
