The MIB module for Block Serial Tunneling.

Overview of BSTUN MIB

MIB description

The BSTUN MIB provides the configuration and operational information 
on Cisco's blocked serial tunnelling implementation.  The following 
entities are managed:
 1) Global BSTUN information
 2) BSTUN groups
 3) BSTUN ports
 4) BSTUN routes

The following example configuration shows how the BSTUN MIB returns
BSTUN information, from either CISCO A or CISCO B.

 HOST == BSC  == Cisco A == IP Network == Cisco B == BSC   == BSC
         line                                        line     device

1) The BSTUN global entry identifies the IP address by which the
   router is known to other BSTUN peers, a configurable SAP value
   on which to listen to LLC2 peers, and keepalive values to maintain
   a session between TCP/IP peers.
2) The BSTUN group table identifies the BSTUN group number and protocol
   type that Cisco A and Cisco B use to route BSC traffic over the 
   IP network.  The table contains an entry for each BSTUN group
   defined on the router. (The group number must be the same in Cisco A 
   and Cisco B, for traffic to flow from one router to the other.)
3) The BSTUN port table identifies the serial interface to the BSC 
   line for which the router is doing serial tunnelling.  The MIB also
   identifies the BSTUN group this interface is defined for, and
   identifies the default routing for unrecognized BSC addresses.
   There is a port entry for each BSTUN-enabled interface on the router.
4) The BSTUN route table has an entry for each address defined for
   routing within the BSTUN group, and an entry for the default routing
   if the 'bstun route all' command is configured.  The route entry
   includes identification of the BSTUN peer, priority, state, and 
   packet and byte counters.
