CISCO-BSTUN-MIB
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.
