hello all
i’m gonna put a short post here what i did for limiting bandwith on a cisco catalyst 2960-x inbound and outbound rate. why you ask? because maybe your a provider and sold a customer a shared internet line for 3Mbit/s
the post is a collection from bits and pieces from different websites
Since you need Layer 3 switch for limiting the bandwith on an interface, you still can work arround it if you have QOS and Layer 2 switch
outbound:
this is simpel to do. for example if you need 3mb outbound trafic
- conf t
- speed 10
- interface gigaEthernet1/0/3
- srr-queue bandwith limit 30
inbound:
this is lil more tricky. you need QOS for this. here are the steps i did to make it work. since im not a fully CISCO CCNA i cant explain all the details. but there are some good sites out there that can explain every class, policy and all.
mls qos
ip access-list extended ACL_CUSTOMER1
permit ip any any
class-map match-all CLASS_CUSTOMER1
match access-group name ACL_CUSTOMER1
policy-map POLICY_CUSTOMER1
class CLASS_CUSTOMER1
police 3000000 1000000 exceed-action drop (example for 3Mbit/s inbound limit) –> try to play with the 1000000 value (burst rate) this one worked for me but possible you need an other burst rate for your environment
interface GigabitEthernet1/0/3
service-policy input POLICY_CUSTOMER1
enjoy and hope this helps
