Priority Commands (Layer 2)
– 639 –
◆ Service time is shared at the egress ports by defining scheduling weights for
WRR, or for the queuing mode that uses a combination of strict and weighted
queuing. Service time is allocated to each queue by calculating a precise
number of bytes per second that will be serviced on each round.
◆ The specified queue mode applies to all interfaces.
Example
The following example sets the queue mode to strict priority service mode:
Console(config)#interface ethernet 1/1
Console(config-if)#queue mode strict
Console(config-if)#

Command Usage
◆ This command shares bandwidth at the egress port by defining scheduling
weights for Weighted Round-Robin, or for the queuing mode that uses a
combination of strict and weighted queuing (page 638).
◆ Bandwidth is allocated to each queue by calculating a precise number of bytes
per second that will be serviced on each round.
