Chapter 4: Configuration Overview
DLCI Mapping/Bridge Map
This menu is used to permit bridging of packets over this DLCI.
Each DLCI or virtual circuit must be assigned a bridge group. The
bridge group treats all virtual circuits as one circuit. Bridge packets
destined to be transmitted out a particular bridge group are copied
and transmitted individually out each DLCI in the bridge group.
However, incoming bridge packets received from one DLCI are not
retransmitted out the other DLCIs in the same bridge group. Any
device in the bridge group must transmit to each DLCI. This re-
quires a fully meshed circuit, meaning each device has a virtual cir-
cuit to each other.
Bridge Map/Active
Write security: 3, Read security: 5
When set to Yes (def), the Router Option Module will bridge pack-
ets to and from this DLCI. Bridge packets are any packets that are
not IP or IPX packets except when the router is turned off, in which
case that particular router's protocol packets are bridged.
When set to No, bridging will not occur.
Bridge Map/Bridge Group
Write security: 3, Read security: 5
The bridge group that this DLCI is part of is specified here as Group
1 or Group 2. These groups correspond to the spanning tree proto-
cols Bridge Group 1 and Bridge Group 2.
DLCI Mapping/Filters
The Router Option Module can block packets in and out of a PVC
port by use of the filters. They are set up in two steps:
1. Define the types of packets that would be of interest in the Con-
figuration/Security/Filter Defines menu, and
2. Set up the filter type and combination of defines that will cause a
packet block.
Filters/In from PVC
Write security: 2; Read security: 5
The packets which come into the Router Option Module via this
PVC can be filtered in three ways:
Disabled (def) - Turns off packet input filtering. No incoming pack-
ets from this PVC are blocked.
