SMC Networks SMC6824M manual Binding a Port to an Access Control List, 112

CONFIGURING THE SWITCH

CLI – This example shows how to create an Ingress MAC ACL and bind it to a port. You can then see that the order of the rules have been changed by the mask.

Console(config)#access-list mac M4	4-139
Console(config-mac-acl)#permit any any	4-140
Console(config-mac-acl)#deny tagged-eth2 00-11-11-11-11-11
ff-ff-ff-ff-ff-ff any vid 3	4-140
Console(config-mac-acl)#end
Console#show access-list	4-150
MAC access-list M4:
permit any any
deny tagged-eth2 host 00-11-11-11-11-11 any vid 3
Console(config)#access-list mac mask-precedence in	4-143

Console(config-mac-mask-acl)#mask pktformat ff-ff-ff-ff-ff-ff any vid

4-144
Console(config-mac-mask-acl)#exit
Console(config)#interface ethernet 1/12	4-171
Console(config-if)#mac access-group M4 in	4-146

Console(config-if)#end Console#show access-list MAC access-list M4:

deny tagged-eth2 host 00-11-11-11-11-11 any vid 3 permit any any

MAC ingress mask ACL:

mask pktformat host any vid Console#

Binding a Port to an Access Control List

After configuring the Access Control Lists (ACL), you can bind the ports that need to filter traffic to the appropriate ACLs. You can only bind a port to one ACL for each basic type – IP ingress, IP egress, MAC ingress and MAC egress.

Command Usage

•You must configure a mask for an ACL rule before you can bind it to a port.

•This switch supports ACLs for both ingress and egress filtering. However, you can only bind one IP ACL and one MAC ACL to any port for ingress filtering, and one IP ACL and one MAC ACL to any port for egress filtering. In other words, only four ACLs can be bound to an interface – Ingress IP ACL, Egress IP ACL, Ingress MAC ACL and Egress MAC ACL.
