See “Configuring the BayStack 450-2M3/2S3 MDAs” on page E-15 for
flowcharts that detail the configuration steps for your BayStack 450-2M3/2S3
MDA.
Enabling a LEC
Every LEC requires the following:
• A unique ELAN name
The ELAN name default value is: default
• An Actual Physical Port number (A1 or A2)
The physical port number default value is: A1
• A port-based VLAN.
You must assign the LEC to a new or existing port-based VLAN (using the
VLAN Configuration screen) the first time a LEC is assigned, or whenever
you issue the Reset to Default Settings command. In all other cases, a LEC’s
VLAN membership is saved and restored following subsequent switch power
cycles.
