Implementing of Layer 2 Access Lists

Configuration Examples for Implementing Layer 2 Access Lists

Resequencing Entries in an Access List: Example

This example shows access-list resequencing. The starting value in the resequenced access list is 1, and the
increment value is 2. The subsequent entries are ordered based on the increment values that users provide,
and the range is from 1 to 2147483646.
When an entry with no sequence number is entered, by default, it has a sequence number of 10 more than the
last entry in the access list.
ethernet service access-list acl_1
10 permit 1.2.3 4.5.6
20 deny 2.3.4 5.4.3
30 permit 3.1.2 5.3.4 cos 5
resequence access-list ethernet service acl_1 10 20
show access-list ethernet-service acl1_1
ipv4 access-list acl_1
10 permit 1.2.3 4.5.6
30 deny 2.3.4 5.4.3
50 permit 3.1.2 5.3.4 cos 5

Adding Entries with Sequence Numbers: Example

In this example, a new entry is added to Ethernet services access list acl_5.
ethernet-service access-list acl_5
2 permit 1.2.3 5.4.3
5 permit 2.3.4. 6.5.4 cos 3
10 permit any dei
20 permit 6.5.4 1.3.5 VLAN vlan3
configure
ethernet-service access-list acl_5
15 permit 1.5.7 7.5.1
end
ethernet-service access-list acl_5
2 permit 1.2.3 5.4.3
5 permit 2.3.4. 6.5.4 cos 3
10 permit any dei
15 permit 1.5.7 7.5.1
20 permit 6.5.4 1.3.5 VLAN vlan3
