10. UPLINK PORT LAG SERVICE CONFIGURATION
OLT uses double uplink protection mechanism to ensure the stability of the service. When the physical
connection between the OLT and the upper equipment is interrupted, the equipment automatically
switches to the standby line to ensure that the service can recover quickly.
OLT supports trunk protection, and achieves load sharing and protection for uplink ports by
configuring trunk.
Prerequisite:
Trunk has been set up on the end equipment, and the working rate and the VLAN property are
consistent with the end.
Relevant information:
OLT supports two types of link trunk modes: static trunk mode and dynamic trunk mode. Static
aggregation mode refers to adding multiple physical ports directly to the Trunk group to form a
logical port. This approach is relatively simple, but it is not good for observing the state of the trunk
port.
The dynamic aggregation mode dynamically trunk multiple physical ports into a Trunk group to form
a logical port to realize load sharing between the out and inbound traffic in each member port. LACP
automatically generates aggregations to obtain maximum
bandwidth.
OLT's trunk capabilities follow the following principles: the member ports must work in full duplex
mode, and the working rate and the VLAN attribute must be consistent.
10.1. Dynamic trunk configuration steps
In the uplink interface configuration mode, and enable LACP mode.
OLT (config) #interface xe1 / 1
OLT (config-xe1 / 1) #lacp active (or passive)
OLT (config) #interface xe1 / 2
OLT (config-xe1 / 2) #lacp active (or passive)
Description:
OLT supports 2 port trunk ways, Active and Passive.
Active:LACP active negotiation mode (default mode);
Passive:LACP the passive mode of negotiation.
It is recommended to set one port trunk mode to be active, another port to be passive, or both ports
to be active.
Configure LACP system priority.
