Creating a Two-Rate Rate-Limit Profile

To create or modify a two-rate rate-limit profile, use the following commands with the two-rate keyword:

rate-limit-profile command
ipv6 rate-limit-profile command
mpls rate-limit-profile command
l2tp rate-limit-profile command

The following example creates a rate-limit profile named hardlimit9Mb. This rate-limit profile, when included as part of a rule in a policy list, sets a hard limit on the specified committed rate with no peak rate or peak burst ability:



host1(config)#ip rate-limit-profile hardlimit9Mb
two-rate 

host1(config-rate-limit-profile)#committed-rate
9000000 

host1(config-rate-limit-profile)#committed-burst
20000 

host1(config-rate-limit-profile)#committed-action
transmit 

host1(config-rate-limit-profile)#conformed-action
drop 

host1(config-rate-limit-profile)#exceeded-action
drop 

host1(config-rate-limit-profile)#mask-val
255

The following example modifies the rate-limit profile named hardlimit9Mb to include an exceeded action that marks the packets that exceed the peak rate. This marking action sets the DS field in the ToS byte (the six most significant bits) to the decimal value of 7 using a mask value of 0xFC:



host1(config)#ip rate-limit-profile hardlimit9Mb
two-rate 

host1(config-rate-limit-profile)#exceeded-action
mark 7 

host1(config-rate-limit-profile)#mask-val
252

To set IP precedence in the ToS byte, use the mask value of 0xE0, for visibility into the three most significant bits.
