How to limit total bandwidth ( Tx + Rx ) in a sub interface ?

[Chanuka D]

Dear fellow engineers,

We are a small ISP and we have customers who subscribe our IP transit services. Currently I'm using class-map and policy-map to limit their bandwidth as you can see in this config. Then I apply policy map into sub interface in both directions using service-policy input and service policy output command. The problem I'm facing now is this allows customer to use download 100M and upload 100M if they subscribe 100Mbps. Now I need cap their total traffic which combines upload and download into 100Mbps. Since I'm using sub interface bandwidth command is not available. How do I achieve this ?

match any

policy-map SDW00014

police 55000000 conform-action transmit exceed-action drop

Hello, exceed-action is the action to take on packets when exceeded the rate limit. You have the transmit key word so it will transmit anything exceeding your police statement. (i.e. pass traffic as normal)

Normally you use exceed-action drop or violate-action drop, where anything to the limit permitted, but anything past the limit will be dropped.

Hope this helps.
