Configuring Vlan Maps - Cisco Catalyst 2960-XR Security Configuration Manual

Configuring IPv4 ACLs

Configuring VLAN Maps

To create a VLAN map and apply it to one or more VLANs, perform these steps:
Before You Begin
Create the standard or extended IPv4 ACLs or named MAC extended ACLs that you want to apply to the
VLAN.
SUMMARY STEPS
1. vlan access-map name [number]
2. match {ip | mac} address {name | number} [name | number]
3. Enter one of the following commands to specify an IP packet or a non-IP packet (with only a known MAC
address) and to match the packet against one or more ACLs (standard or extended):
4. vlan filter mapname vlan-list list
DETAILED STEPS
Command or Action
Step 1 vlan access-map name [number]
Example:
Switch(config)# vlan access-map map_1
20
Step 2 match {ip | mac} address {name | number}
[name | number]
Example:
Switch(config-access-map)# match ip
OL-29434-01
• action { forward}
Switch(config-access-map)# action forward
• action { drop}
Switch(config-access-map)# action drop
Purpose
Creates a VLAN map, and give it a name and (optionally) a number. The
number is the sequence number of the entry within the map.
When you create VLAN maps with the same name, numbers are assigned
sequentially in increments of 10. When modifying or deleting maps, you
can enter the number of the map entry that you want to modify or delete.
VLAN maps do not use the specific permit or deny keywords. To deny a
packet by using VLAN maps, create an ACL that would match the packet,
and set the action to drop. A permit in the ACL counts as a match. A deny
in the ACL means no match.
Entering this command changes to access-map configuration mode.
Match the packet (using either the IP or MAC address) against one or more
standard or extended access lists. Note that packets are only matched against
access lists of the correct protocol type. IP packets are matched against
standard or extended IP access lists. Non-IP packets are only matched against
named MAC extended access lists.
