qos rcv-queue multicast rate-limit
Configures a cap on the maximum rate for multicast packet expansion.
Synopsis qos rcv-queue multicast rate-limit rate [burst burst-size]
no qos rcv-queue multicast rate-limit
Operands rate Specifies the maximum rate for multicast packet expansion in units of
packets per second (pkt/s). Valid values range from 6500
through 20000000 pkt/s.
burst burst-size Configures a cap on the maximum burst size for multicast packet
expansion. Valid values range from 50 through 65535 packets.
Defaults The burst size is 4096 packets. The rate value is 3000000 pkt/s.
Command Modes Global configuration mode
Description Use this command to configure a cap on the maximum rate for multicast packet expansion,
for example packet replication. This rate limit is applied uniformly across the entire system. This
rate limit is enforced independently by each switch.
Usage Guidelines This command is not supported on VDX 8770-4 and VDX 8770-8 switches.
The rate parameter places a cap on the sum of the first level expansion (for example, the ingress
packets replicated for each egress switch) plus the second level expansion (for example, packets
replicated for egress interfaces on the switch).
The burst burst-size parameter represents the maximum number of multicast packet expansion
that can be performed back-to-back as a single burst in units of packets (pkt).
Enter no qos rcv-queue multicast rate-limit to return the multicast packet expansion rate limit to
the default settings.
Examples To lower the maximum multicast packet expansion rate to 10000 pkt/s:
switch(config)# qos rcv-queue multicast rate-limit 10000
To return the system to the default multicast packet expansion rate limit values:
switch(config)# no qos rcv-queue multicast rate-limit
