Chapter 13 LANE Services

Round-robin.

This is the default method set when creating a new ELAN. No user configuration is required.

The LEC is assigned to the next distributed LES address in sequence (each distributed LES is used in turn). LECs assignment to the most suitable LES is left to chance.

Group address

User configuration is required.

Every distributed LES on the ELAN is assigned a group address. Note, the same group address is used by all the distributed LESes. It is this address that is returned to every LEC by the LECS, when requesting to join the ELAN. The LEC will then connect with the “nearest” distributed LES if PNNI routing is enabled (the switch that offers the least number of hops will be selected).

Longest Match with LEC address.

No user configuration is required.

The LES address supplied by the LECS is the one which best matches the ATM address of the LEC. This in practice should also provide the nearest distributed LES to the requesting LEC.

Note this may not necessarily be true, should you be using manual configured addresses or non-standard ATM addresses for M770 ATM switches that are hosting the LEC.

The Management LEC in an Avaya M770 ATM Switch

•The M770 ATM Switch has one management LEC for managing the M770 ATM Switch. It is located on the Master agent module in the switch and supports several high-level protocols such as:

—Telnet for a command-line interface.

—UDP for SNMP management and TFTP software upgrades.

—BOOTP for obtaining M770 ATM Switch’s IP address from a server.

—ICMP for PING inward and outward for IP network configuration diagnosis.

•By default, the M770 ATM Switch management LEC uses the Burnt-In Address (BIA) as its MAC address. This address can be overridden and a Locally Administered Address (LAA) can be assigned. The management LEC will register this address with the LES that is hosting the ELAN that the LEC wishes to join.

•The M770 ATM Switch management LEC, by default, requests to join an Ethernet ELAN.
