An example configuration of the aggregation switch is provided below. This example covers configuring a 25G interface to connect an access switch or OLT LTX-8/16 rev.B, LTX-8/16C, configuring a 100G interface to connect LTX-8/16, and configuring a 100G interface as an uplink interface to upstream data network equipment.
Apart from configuring interfaces the example shows configuring IGMP snooping, LLDP, AAA, NTP.
