Conguring IPv6 Flow-Based Mirroring
This section describes how to congure IPv6 ow-based mirroring in the monitor session.
You can congure IPv6 ow-based mirroring under monitor session. The IPv6 ow-based mirroring is supported in SPAN, RSPAN,
and ERSPAN monitor sessions. By default, all mirror ACLs is considered as implicit permit.
The Dell EMC Networking OS creates a separate
logical group out of a physical CAM region for IPv6 mirroring. In order to enable this feature, you have to congure ipv4udfmirracl
CAM region, which supports IPv6 mirror ACL along with IPv4 mirror ACLs. Both IPv4 and IPv6 mirror ACLs can co-exist in a monitor
session.
Pre-requisite
Before you congure IPv6 ow-based mirroring, allocate a CAM ipv4udfmirracl region, so that you can apply the ACL that is created
to the monitoring session.
• Allocate a CAM region using the following command.
cam-acl l2acl number ipv4acl number ipv6acl number ipv4qos number l2qos number l2pt number
ipmacacl number vman-qos number [ipv4udfmirracl number]
NOTE
:
If you congure IPv6 mirroring without conguring ipv4udfmirracl CAM region, following error message appears.
% Error: IPv6 Mirror-Access-list not supported on this CAM profile. Please remove the ipv6
access-group.
