Configuring IPv6 Flow-Based Mirroring
This section describes how to configure IPv6 flow-based mirroring in the monitor session.
You can configure IPv6 flow-based mirroring under monitor session. The IPv6 flow-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 new dedicated CAM region ipv6mirracl for IPv6 mirror ACL, which does not have any impact on IPv6 user
ACL. The IPv6 mirror ACL region priority is less than IPv6 user ACL region, so that the traffic matching the user ACL takes
priority in permit/deny action. Both IPv4 and IPv6 mirror ACLs can co-exist in a monitor session.
Pre-requisite
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 [ipv6mirracl number]
NOTE:
If you configure IPv6 mirroring without configuring ipv6mirracl CAM region, following error message appears.
% Error: IPv6 Mirror-Access-list not supported on this CAM profile. Please remove the
ipv6 access-group.
Enabling IPv6 Flow-Based Monitoring
To enable IPv6 flow-based mirroring, use ipv6 access-group access-list-name command under monitor session.
You can apply a new IPv6 ACL in a monitor session, when an ACL is already applied. If so, the new ACL will replace the old and
overwrite it.
1. Create a monitoring session.
CONFIGURATION mode
monitor session session-id
2. Enable flow-based monitoring for a monitoring session.
MONITOR SESSION mode
flow-based enable
3. Specify the source and destination port and direction of traffic.
MONITOR SESSION mode
source sourceport destination destination-port direction rx
4. For flow-based monitoring with ACL applied on the interface, define IPv6 access-list rules that include the monitor
keyword. Dell EMC Networking OS only considers traffic matching rules with the monitor keyword for flow-based
monitoring with ACL applied on the interface.
CONFIGURATION mode
ipv6 access-list
To define access lists, see the Access Control Lists (ACLs) chapter.
5. Apply the IPv6 ACL to the monitored port.
MONITOR SESSION mode
ipv6 access-group access-list-name
Following is an example configuration for flow-based monitoring mirroring ACL applied on an interface.
DellEMC(conf)#monitor session 10
DellEMC(conf-mon-sess-10)#flow-based enable
DellEMC(conf)#ipv6 access-list testflow
