Configuring Layer 2 Acl - 3Com WX3000 Series Operation Manual

If the ACL is created with the auto keyword specified, the newly created rules will be inserted in the
existent ones by depth-first principle, but the numbers of the existent rules are unaltered.
Configuration Example
# Configure ACL 3000 to permit the TCP packets sourced from the network 129.9.0.0/16 and destined
for the network 202.38.160.0/24 and with the destination port number being 80.
<device> system-view
[device] acl number 3000
[device-acl-adv-3000] rule permit tcp source 129.9.0.0 0.0.255.255 destination 202.38.160.0
0.0.0.255 destination-port eq 80
# Display the configuration information of ACL 3000.
[device-acl-adv-3000] display acl 3000
Advanced ACL
Acl's step is 1
rule 0 permit tcp source 129.9.0.0 0.0.255.255 destination 202.38.160.0 0.0.0.255
destination-port eq www

Configuring Layer 2 ACL

Layer 2 ACLs filter packets according to their Layer 2 information, such as the source and destination
MAC addresses, VLAN priority, and Layer 2 protocol types.
A Layer 2 ACL can be numbered from 4000 to 4999.
Configuration Prerequisites
To configure a time range-based Layer 2 ACL rule, you need to create the corresponding time
ranges first. For information about time range configuration, refer to
The settings to be specified in the rule, such as source and destination MAC addresses, VLAN
priorities, and Layer 2 protocol types, are determined.
