Applying Acl Rules To Ports In A Vlan; Displaying And Maintaining Acl Configuration - 3Com 5500-EI PWR Install Manual

[Sysname-Ethernet1/0/1] packet-filter inbound ip-group 2000

Applying ACL Rules to Ports in a VLAN

By applying ACL rules to ports in a VLAN, you can add filtering of packets on all the ports
in the VLAN.
Note:
The ACL rules are only applied to ports that are in the VLAN at the time the packet-filter
vlan command is executed. In other words:
A port joining the VLAN later will not use the ACL rules for packet filtering.
A port leaving the VLAN later will keep using the ACL rules for packet filtering.

information about defining an ACL, refer to
