7.26 Mirroring configuration
1
Traffic mirroring is a feature of the router that allows for redirection of traffic from a specific port of
the router to another port of the same router (local mirroring) or to a remote device (remote mirroring).
Objective: Establish remote mirroring of traffic through VLAN 50 from gi1/0/11 interface to be sent
to server for processing purposes.
Fig. 7.28—Network structure
Solution:
First, do the following:
Create VLAN 50.
On gi 1/0/5 interface, add VLAN 50 in 'general' mode.
Main configuration step:
Specify VLAN that will be used for transmission of mirrored traffic:
еsr1000(config)# port monitor remote vlan 50
For gi 1/0/5 interface, specify a port for mirroring:
еsr1000(config)# interface gigabitethernet 1/0/5
еsr1000(config-if-gi)# port monitor interface gigabitethernet 1/0/11
For gi 1/0/5 interface, specify remote mirroring mode:
еsr1000(config-if-gi)# port monitor remote
Configuration changes will take effect when the configuration is applied:
esr1000# commit
Configuration has been successfully committed
esr1000# confirm
Configuration has been successfully confirmed

In the current firmware version, this functionality is supported only by ESR-1000 router.
