Identifying the LES Address

Typically, more than one LAN Emulation Server (LES) is configured in an ATM network, and each is responsible for the identification and location of a subset of ELANs on the network. Identifying which LES is responsible for a target ELAN can be accomplished either automatically or manually. Automatic identification is managed by the LAN Emulation Configuration Server (LECS) based on "look-up" tables previously configured by the network administrator. Automatic identification is the default operational mode. You can choose, however, to disable automatic identification, and identify the LES address manually.

Note:  Identifying LES addresses is most easily managed on the LAN Emulation Configuration Server (LECS). Managing the address tables centrally on the LECS is easier than changing the LES address on each VNswitch module, especially when the physical configuration of a large network changes.
