WS-C3850-12XS || internet & interanet blocking

Hi All,

 

I need to block internet & internet of one particular user so how can we block this communication i only have mac information of this user.

I have L3 switch WS-C3850-12XS so is there any kind of filtering option so we can enable it on L3 switch it self so user will not get even IP address.

On l3 switch we have all the SVI.

Hi, 

you can use Class-map, Policy-map and then apply it to the designated port. see example below

class-map match any unwanted-pc's

match source-address mac aaaa.bbbb.cccc

match source-address mac nnnn.jjjj.dddd

match source-address mac oooo.llll.pppp

!

policy-map block

class unwanted-pc's

drop

!

int gi 0/1 <--------------------- designated port which the PC is connected

description "LAN Interface"

service-policy input block
