Dell EMC Networking OS Behavior: Virtual router redundancy protocol (VRRP) hellos and internet group management

protocol (IGMP) packets are not affected when you enable egress ACL filtering for CPU traffic. Packets sent by the CPU with

the source address as the VRRP virtual IP address have the interface MAC address instead of VRRP virtual MAC address.

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]

[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.
