2975 limit port bandwidths

[mcusine]

Hi,

I am trying to limit to 10 MB one gigabitethernet interface.

I am trying to apply the following :

policy-map bedsides
description Limite 10Mb Bedsides
class Bedsides

math ip
  police 10000000 8000 exceed-action drop
class class-default
  police 10000000 8000 exceed-action drop

interface xx

service-police input bedsides

I need to math multicast traffic only or all traffic, if I configure math any the switch give a message that it's not possible due a interface type.

I configured IP and a class-default.

What is the best way to limit the traffic in the switch model?. Any other option ?. Any command to check it's working fine?.

Thanks in advance and best regards,

Mauricio

I am trying to limit to 10 MB one gigabitethernet interface.

Try this basic command:

or

Hi Mauricio,

You can allocate specific bandwidth to one interface. also to you can do the same to Vlan's.

See the below two individual steps may help in your scenario.

STEP-1:

Apply rate-limit on each interface in your 2975
Example (for 1024kbits):

Router# conf t
Router(config)# int gig 3/24
Router(config-if)#rate-limit input 1000000 187500 375000 conform-action transmit exceed-action drop
Router(config-if)#rate-limit output 1000000 187500 375000 conform-action transmit exceed-action drop

STEP-2:

Policy a specific VLAN number on VLAN interface.

class-map vlan5
match vlan 5
match class-map class-default

policy-map vlan5-limit
class vlan5
police 8000 1500 1500 conform-action transmit exceed-action drop violate-action drop

int vlan5
service-policy input vlan5-limit

After you apply this configuration, the traffic with VLAN 5 coming from any will be policed at 8Mbps. Like that you can allocate how much bandwith you want.

Hope this will help you.

Hi Naidu,

Thanks for your email.

In the 2975 there is no exist rate-limit command :

% Unrecognized command
SW_P1R2(config-if)#rate-limit

and it's only a leyer 2 switch

Do you think that applying the service-policy to vlan will work? In the case of the answer be yes, it's a not very ussefll solution because I need to know how many interface will connect to the vlan, and I am not sure, and after I add one new interface to the vlan, it's necesary to madify the values.

Do you have any other idea that only apply to the interface?.

Thanks in advance and best regards,

Mauricio

Hi Naidu,

Thanks again for your answer, I will try these configuration.

Do you think these conf will math multicast traffic and/or any traffic.

As a  posted in my frist message the Switch don't allow to configure math any.

Thanks and best regards,

Mauricio
