Avaya 580 - Manual (Page 704)

25-30 User Guide for the Avaya P580 and P882 Multiservice Switches, v6.1
Chapter 25
The switch uses queue 0 to forward protocol packets (ARP, VRRP, OSPF,
and so on) to the supervisor module. If you enable policing on queue 0, be
sure to allocate the queue enough bandwidth for management packets and
learned packets. Failure to allocate enough bandwidth to the queue may
result in poor network performance. Do not disable this queue by allocating
it 0 bits per second (bps). If you disable the queue, all protocol packets and
learned packets are discarded before reaching the supervisor module.
For information about how to set up policing, see “ Setting Up Policing ”
later in this chapter.
* Note: Avaya recommends that you do not set a port using policing as
the source port or mirror port for a port mirror. When the switch
limits the bandwidth of a port, packets are subject to random
drop. If packets from a source port or mirror port are dropped,
the mirror traffic may not match the source traffic.

Setting Up Policing
Use the set port police command to enable or disable policing for ingress
traffic on a port. For information on how policing works, see “
Ingress
Policing ” earlier in this chapter.
The syntax for this command is:
(configure)# set port police {{ | }
[..., { | }] | all-ports} queue
{bit-rate normal-burst | disable}
