Usage Guidelines
Glean fast-path is enabled by default. If glean fast-path programming does not occur due to adjacency resource
exhaustion, the system falls back to regular glean programming.
The hardware rate-limiter layer-3 glean-fast {packets | disable} [module module [port start end]] command
sends packets to the supervisor from F2e, M1, or M2 Series modules.
The hardware rate-limiter portgroup-multiplier multiplier module module command applies the multiplier
to the rate limit. For example, if you configured the ttl rate-limiter as 1000 pps and the multiplier value was
0.5, each ASIC instance would be programmed with 500 pps.
This command does not require a license.
Examples
This example shows how to configure a rate limit for control packets:
switch# configure terminal
switch(config)# hardware rate-limiter layer-3 control 20000
This example shows how to revert to the default rate limit for control packets:
switch# configure terminal
switch(config)# no hardware rate-limiter layer-3 control
This example shows how to configure the port group multiplier:
switch# configure terminal
switch(config)# hardware rate-limiter portgroup-multiplier 0.5 module 3
