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:

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.
