Syntax: symmetric-flow-control set 1 | 2 xoff <%> xon <%>
symmetric-flow-control set 1 sets the XOFF and XON limits for 1G ports.
symmetric-flow-control set 2 sets the XOFF and XON limits for 10G ports.
For xoff <%>, the <%> minimum value is 60% and the maximum value is 95%.
For xon <%>, the <%> minimum value is 50% and the maximum value is 90%.
Use the show symmetric command to view the default or configured XON and XOFF thresholds.
Refer to
“Displaying symmetric flow control status”
on page 43.
Changing the total buffer limits
This section describes how to change the total buffer limits described in
“About XON and XOFF
thresholds”
on page 41. 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.
PowerConnect(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.
PowerConnect(config)# symmetric-flow-control set 2 buffers 128
Total buffers modified, 1G: 320, 10G: 128
Syntax: symmetric-flow-control set 1 | 2 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 43.
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.
Syntax: show symmetric-flow-control
PowerConnect(config)# show symmetric
