The MIB module for serial Tunneling. Overview of STUN MIB MIB description The STUN MIB provides the configuration and operational information on Cisco's serial tunnelling implementation. The following entities are managed: 1) Global STUN information 2) STUN groups 3) STUN ports 4) STUN routes The following example configuration shows how the STUN MIB returns STUN information, from either CISCO A or CISCO B. HOST == SDLC == Cisco A == IP Network == Cisco B == SDLC == SDLC line line device 1) The STUN global entry identifies the IP address by which the router is known to other STUN peers. 2) The STUN group table identifies the STUN group number and protocol type that Cisco A and Cisco B use to route SDLC traffic over the IP network. The table contains an entry for each STUN group defined on the router. 3) The STUN port table identifies the serial interface to the SDLC line for which the router is doing serial tunnelling. The MIB also identifies the STUN group this interface is defined for, and identifies the default routing for unrecognized SDLC addresses. There is a port entry for each STUN-enabled interface on the router. 4) The STUN route table has an entry for each address defined for routing within the STUN group, and an entry for the default routing if the 'stun route all' command is configured. The route entry includes identification of the STUN peer, priority, state, whether local acknowledgment is enabled, and packet and byte counters.
