VLAN OVERVIEW
The following sections provide an overview of the VLAN functionality of
the BRIM-A6DP and give step-by-step instructions on how to create and
configure VLANs.
When the BRIM-A6DP is first initialized, a LEC is automatically created
by the BRIM-A6DP. This LEC contacts the LAN Emulation
Configuration Server (LECS) so it can be assigned to an Emulated LAN
(ELAN). The BRIM-A6DP also automatically creates a default VLAN
upon first initialization, and assigns all front panel Ethernet interfaces to
this VLAN. Once the LAN Emulation Configuration Server has
determined which ELAN the LEC belongs to, the BRIM-A6DP
automatically maps the ELAN to the VLAN so that all front panel
Ethernet ports can communicate over the ATM network. Once the
BRIM-A6DP has performed these automatic functions, the user has the
choice to perform the following tasks:
•
Remove front panel Ethernet ports from the VLAN
•
Create additional LECs, and assign front panel Ethernet ports to new
VLANs
•
Create Ethernet-only (front panel, port-to-port) VLANs.
Once a VLAN is created, any traffic that is originated on that particular
VLAN will be confined to that VLAN even if the destination address of
the frame(s) is broadcast, multicast or unknown unicast.
!
CAUTION
Read this section thoroughly before configuring VLANs from
the VLAN Assignment screen. If the guidelines and directions
outlined in the following sections are not complied with, poor
network performance will occur.
