Transparent Mode Scenario; Configuring Lacp - Cisco ONS 15454 SDH Configuration Manual

Configuring LACP

transparent mode is that the network bandwidth is not wasted. However. the disadvantage is that there is
no card protection between the CPE and UNI (ONS 15454) because all the links in the ML card bundle
belong to the same card.

Transparent Mode Scenario

In Figure
mode is enabled when the LACP packets are transmitted without any processing on a card. While
functioning in this mode, the CE-100T-8 cards pass through LACP packets transparently so that the two
CPE devices perform the link aggregation. To operate in this mode, no LACP configuration is required
on the CE-100T-8 cards.

Configuring LACP
To configure LACP over the EtherChannel, perform the following procedure, beginning in global
configuration mode:
Command
Step 1
Router(config)# int port <interface-number>
Step 2
Router(config-if)# int fa <facility-number>
Step 3
Router(config-if)# channel-group < channel-number > mode ?
Step 4
Router(config-if)# channel-group < channel-number > mode active
Configure and set the LACP port's priority. This configuration is optional.
Step 1
Router(config-if)# exit
Step 2
Router(config-if)# int fa < facility-number >
