Sets symmetric flow control parameters.
1G: Buffers: 272; XOFF Limit: 91; XON Limit: 75
10G: Buffers: 416; XOFF Limit: 91; XON Limit: 75
port-type
| Specifies the port type. The port type can be one of the following:
| ||||||
buffers
value
| Sets the total buffer limits. The value can range from 64 through 320 for 1G ports and from 64 through 1632 for 10G ports. The default value for 1G ports is 272 and for 10G ports is 416 .
| ||||||
unit
unit-value
| Specifies the buffer limit for a stack unit.
| ||||||
xoff
num
| Sets the XOFF limit. The minimum value is 60 percent, and the maximum value is 95 percent.
| ||||||
xon
num
| Sets the XON limit. The minimum value is 50 percent and the maximum value is 90 percent.

Global configuration mode
Use the show symmetric command to view the default or configured buffer limit or XON and XOFF thresholds.
The no form of the command deletes the configured symmetric flow control values.
The following example changes the thresholds for all 1G ports.
device(config)# symmetric-flow-control set 1 xoff 91 xon 75
The following example changes the total buffer limit for all 10G ports.
device(config)# symmetric-flow-control set 2 buffers 128
Total buffers modified, 1G: 320, 10G: 128
