monitor session session-id
2 Enable ow-based monitoring for a monitoring session.
MONITOR SESSION mode
flow-based enable
3 Specify the source and destination port and direction of trac.
MONITOR SESSION mode
source source—port destination destination-port direction rx
4 For ow-based monitoring with ACL applied on the interface, dene IPv6 access-list rules that include the monitor keyword. Dell
EMC Networking OS only considers trac matching rules with the
monitor keyword for ow-based monitoring with ACL applied on
the interface.
CONFIGURATION mode
ipv6 access-list
To dene 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
Example of the IPv6 ow-based mirroring ACL applied on the interface
Following is an example conguration for ow-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
DellEMC(config-ext-nacl)#seq 5 permit icmp any any count bytes monitor
DellEMC(config-ext-nacl)#seq 10 permit ipv6 10::/64 any count bytes monitor
DellEMC(config-ext-nacl)#seq 15 deny udp any any count bytes
DellEMC(config-ext-nacl)#seq 20 deny tcp any any count bytes
DellEMC(config-ext-nacl)#exit
DellEMC(conf)#interface tengigabitethernet 1/1
DellEMC(conf-if-te-1/1)#ipv6 access-group testflow in
The following is sample running-conguration of IPv6 ow-based mirroring with ACLs applied to monitor sessions.
