IPX Map/IARP
Write security: 3, Read security: 5
When this is set to
Yes (def), the Express L768/L1.5 will send Inverse ARP
packets to determine the IPX network on the other end of the virtual circuit. If
the IARP is responded to, a route is placed in the IPX route table. A setting of
No means that the IPX network is to be assigned to the link statically using the
IPX Map/Link Network parameter. The Express L768/L1.5 will always re-
spond to Inverse ARP requests.
IPX Map/Link Network
Write security: 3, Read security: 5
This is the IPX network of the link or of the other device’s LAN. When this
DLCI becomes active, the Express L768/L1.5 will add a route to this network
in the IPX routing table. This address is also used by the Express L768/L1.5 to
respond to Inverse ARP requests. If this IPX address is left as 0, the link is
treated as unnumbered and the Express L768/L1.5 responds to the Inverse
ARP with its Ethernet IPX address.
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 requires a
fully meshed circuit, meaning 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 L768/L1.5 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 pro-
tocol 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.
