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 requires a fully meshed circuit, mean-
ing each device has a virtual circuit to each other.
Bridge Map/Active
Write security: 3, Read security: 5
When this is set to Yes (def), the Express 4100/4110 will bridge
packets 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. A
setting of No means that no bridging will 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
protocols Bridge Group 1 and Bridge Group 2.
DLCI Mapping/Filters
The Express 4100/4110 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 Configuration/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 Express 4100/4110 via this PVC
can be filtered in three ways:
Disabled (def) Turns off packet input filtering. No
incoming packets from this PVC are
blocked.
Block All All incoming packets from this PVC
are blocked except as defined in the
Filters/In Exceptions
list.
Forward All All incoming packets from this PVC
are not blocked except as defined in
the Filters/In Exceptions list.
