Cajun M770 ATM Switch User’s Guide
Note:
Ensure that the number of modules hosting a specific LES/BUS (e.g. default)
does not exceed the maximum number of LESes per ELAN as defined in:
lan elan maxles’
(default 5, maximum 10).
5
Determine if secure “Closed” ELANs are required. If required then you will
need to set-up an ELAN client database in the Cajun M770.
For information about setting up ELAN clients, see Chapter 16 Managing ELAN
Clients.
— By default when ELANs are created they are set-up as “Open” ELANs.
Recommended Redundant LANE Services Setup
On every module, the user has the ability to setup redundant LANE services. On
each M770 ATM switch that contains N modules, you have the flexibility to
configure N resilient LECS hosting ELANs that can be redundant N times. LANE
redundancy is not just switch wide, but network wide. Each module in every
switch can host redundant LANE services. We do not recommend that you place
redundant LANE services on every module. In the event that you want to
investigate where clients are registered and to look at the LECS, you need to look at
every module in his network. The Cajun LaneMaster application helps you
configure your redundant LANE services. To help you decide where to put the
LANE services and to minimize configuration time, we recommend the following:
Example
for LANE Configuration
The default LANE configuration of the Wizard:
LECS:
Setup 2 resilient LECS on two different switches. One of the LECS
should have a higher priority than the other.
LES:
Setup 5 distributed LESs for each ELAN. Configure each LES on a
separate switch and if there are less than 5 switches, configure a LES
on multiple modules in each switch.
ELAN:
Ethernet ELAN named default
LES/BUS:
Ethernet LES named default
LECS:
Remote at the well known address (wka)
LEC:
Configured to join the Ethernet ELAN default
