Examples
This example shows how to set all buffer queues to 25 percent for multicast and unicast traffic
 
switched out all Fast Ethernet ports:
xon-limit 
xoff-limit
When the IngressRX threshold type is chosen, sets the Xon 
and Xoff limits. When this limit is reached, the receiving 
port sends flow control pause frames the sending port 
requesting that transmissions be “turned off”. Once the 
sending port responds to the request, the frames will empty 
until the Xon threshold is reached. The receiving port then 
ceases sending flow control pause frames allowing 
transmissions from the sending port to be “turned back on”.
Valid values are 1 to 100, rounded to the nearest 0.1%, and 
must be entered in decimal format: 00.0. In order for proper 
configuration of buffer settings, the receive-buffer 
percentage must be higher than the xoff-limit, which must be 
higher than the xon-limit
NOTE: Xon-limit and Xoff-limit settings are only 
active when flow control is enabled. To check the 
status of flow control on one or more ports, use the 
show port flowcontrol command 
(
). 
unicast-per-port 
multicast 
router-block
When the EgressGeneral threshold type is chosen, sets the 
percentage to allocate to each buffer. Valid values are 1 to 
100, rounded to the nearest 0.1%, and must be entered in 
decimal format: 00.0
