[c-nsp] mac filter on switch

[james list]

Dear experts,

I’ve a customer switch C3750 (12.2(35)), is there a way to permit on a
specific port only a group of mac address which could generate traffic
towards the switch ?

I’ve tried mac acl but I do not get the expected result.

Any idea, example or www reference is appreciated.

Thanks in advance

Cheers

James
