Implementation Information

ACLs and prefix lists can only drop or forward the packet or traffic. Route maps process routes for route redistribution. For example, a

route map can be called to filter only specific routes and to add a metric.

Route maps also have an “implicit deny.” Unlike ACLs and prefix lists; however, where the packet or traffic is dropped, in route maps, if a

route does not match any of the route map conditions, the route is not redistributed.

The implementation of route maps allows route maps with the no match or no set commands. When there is no match command, all

traffic matches the route map and the set command applies.

Configuring UDF ACL

To configure a User Defined Field (UDF) ACL:

1. Enable UDF ACL feature on a switch.

CONFIGURATION mode

feature udf-acl

DellEMC(conf)#feature udf-acl

2. Change the default CAM allocation settings or reconfigure new CAM allocation settings and enable IPV4 UDF.

CONFIGURATION mode

cam-acl {default | l2acl number ipv4acl number ipv6acl number ipv4qos number l2qos number

l2pt number ipmacacl number [vman-qos | vman-dual-qos number] ecfmacl number [nlbclusteracl

number] ipv4pbr number }openflow number | fcoe number} [ipv4udfenable] [iscsioptacl number]

[vrfv4acl number]

DellEMC(conf)#cam-acl l2acl 1 ipv4acl 8 ipv6acl 2 ipv4qos 0 l2qos 2 l2pt 0 ipmacacl 0 vman-

qos 0 ecfmacl 0 ipv4udfenable

3. View the currently configured CAM allocation.
