4The Network Management Station should have direct access to at least one LECS in the network, when an ELAN fails.
5Do not use too many primary LESs on a single switch. Distribute the LESs across the backbone.
6Sixteen is the default number of active LANE Servers (LES) per CoreBuilder7000 that can be viewed in LAN Emulation maps. You can change the number of managed LANE servers for all CoreBuilders in the network by editing the following file:
\TranscendNT\ATMvLAN\runtime\cnf\numcpsrvs.cnf
Change the number in the file to the number of LANE servers used. The number should be less than or equal to the number of servers in the CoreBuilder 7000.
If you manually change the LECS database on a CoreBuilder 7000 using the console terminal interface, the Backbone and Services Configuration tool may have problems reading the database in the CoreBuilder. If an error message appears, manually reset the LECS database to the factory default.
Workaround | At the terminal prompt select 1, 2 and 7. | |
| (1) SYS:Platform config | |
| (2) | RES:Reset config to factory default |
| (7) | RBO:Reboot |
Description of LAN Emulation Services (LES/BUS/LECS) may be activated on each LES/BUS Redundancy CoreBuilder 7000 switch in the network. LAN Emulation Services allow
you to create Emulated LANs (ELANs) on the ATM/Ethernet based infrastructure. Given that each Emulated LAN is serviced by only one LES/BUS pair, this could potentially become a point of failure. The LES/BUS redundancy feature allows you to configure an additional LES/BUS pair (running elsewhere in the network, on a different CoreBuilder 7000) as a dynamic/hot backup for the primary LES/BUS pair servicing a particular ELAN.
