In case of using FEC, the real bandwidth decreases by

~10%

Step 7.

Adjust time settings of optical transceivers if needed.

LTP-8X(config)(if-gpon-0-7)# optics use-custom
LTP-8X(config)(if-gpon-0-7)# optics ...

Optical transceivers should be adjusted only by agreement with Eltex Service
Centre.

Step 8.

Apply the configuration by using the

commit

command.

LTP-8X(config)(if-gpon-0-7)# exit
LTP-8X(switch)(config)# commit

18.4

Port Mirroring Configuration

Port mirroring is used to duplicate traffic on monitored ports by sending ingress and/or egress packets to

the controlling port. Users can define a controlled port and controlling ports and select the type of the traffic
(ingress or egress), which will be sent to the controlling port.

18.4.1

Configuration of the Controlled Port

Step 1.

Mirroring is configured in the terminal switch. Execute the

switch

and

configure

commands

consecutively to switch to the

config view

LTP-8X# switch
LTP-8X(switch)# configure
LTP-8X(switch)(config)#

Step 2.

Configure the "pon-port" mirroring for ingress and egress traffic.

LTP-8X(switch)(config)# mirror rx interface pon port 0
LTP-8X(switch)(config)# mirror tx interface pon port 0

Step 3.

Apply the configuration by using the

commit

command.

LTP-8X(switch)(config)# commit

18.4.2

Configuration of the Controlling Port

Step 1.

Switch to the config view by using the

switch

and

configure

commands.

LTP-8X# switch
LTP-8X(switch)# configure
LTP-8X(switch)(config)#
