Configuring Bridging Services
4-20 114060 Rev. A
Parameter: Source Route Explorer Type
Default: Spanning Tree
Options: Spanning Tree
| All Routes
Function: When the translation bridge software forwards a frame with an unknown
destination address onto the source routed network, it sends the frame as
either an STE (spanning tree explorer) or ARE (all-routes explorer)
frame. By default, the translation bridge is configured to use STE frames,
so as not to burden the source routed network with excessive ARE traffic.
Using STE frames, however, forces all traffic flowing over the translation
bridge to follow the spanning tree route through the network, which may
not be the optimal route.
Instructions: If you are connecting transparently bridged networks across a large
source routed network, you may want to configure the translation bridge
to forward frames as AREs, so that frames can follow routes other than
the spanning tree route across the source routed LAN. Consider, however,
that AREs may generate an unacceptable level of traffic on the larger
network.
MIB Object ID: 1.3.6.1.4.1.18.3.5.1.1.2.11.9
Parameter: SAPS
Default: 000408F0F4FC
Options: Any hexadecimal value
Function: The translation bridge supports the transfer of LLC-based traffic, as
indicated by the SAP (service access point) value. This parameter allows
you to designate the SAPs that identify the protocols you want the
translation bridge to accept and translate. By default, the translation
bridge accepts NetBIOS, SNA, and LNM (LAN Network Manager)
SAPs.
Instructions: Specify SAPs that the translation bridge will accept.
