CISCO-WAN-TOPOLOGY-MIB file content

The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.

Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

       DESCRIPTION
           "A management station can use this MIB module for the 
            maintenance of persistent topology information of the 
            PNNI network. Previously, a management station had to 
            query the network to retrieve the network topology via 
            an Integrated Local Management Interface (ILMI) link.  
            The nodes that are down or the nodes whose ILMI-enabled 
            links are down will not be included in the topology. To 
            rectify this limitation, the concept of persistent
            topology is used. 

            The persistent topology feature requires the following:
       
            - a node configured to be the gateway node
            - PNNI links between the nodes
            - node and feeder database.

            A Gateway Node, for the purpose of this MIB module, is 
            defined to be a node that is capable of maintaining a 
            persistent topology database based on the PNNI Topology 
            State Elements (PTSEs) sent by the other nodes in the 
            PNNI peer group. The topology database is persistent
            across reboots.  

            A feeder, in the context of this MIB, is defined as 
            an ATM switch which does not have PNNI feature. It is 
            connected to a node(with PNNI feature, therefore 
            with routing capability) through a physical link. (The 
            provisioning of the feeder and the link are beyond 
            the scope of this MIB.) When a feeder and the link  
            are provisioned, the feeder will update the routing  
            node with its information(for example: feeder name,  
            the feeder's port ifIndex etc.). The routing node will  
            group these feeder information along with its own 
            information(for example: its node identifier, its feeder
            port's information etc.) and send it to other nodes 
            in the peer group in the PTSE. Upon receiving this
            PTSE, each node will update its database. The same actions
            are repeated when some information are modified on 
            the feeder. A network management station can retrieve  
            these information from a Gateway Node's database. In the
            case of a feeder failure, or a feeder is removed
            from the network, or the feeder's routing node failure,
            the feeder's corresponding entry in the database will
            not be removed. The only way to remove an entry from
            the database is for the network management station to
            delete this entry explicitly.

            A link, in the context of this MIB, is defined as 
            a PNNI link between two PNNI nodes. 

            (a) The nodal information for each node in the peer group 
            stored in the persistent topology database includes: 

            - node id
            - node name
            - Primary IP address
            - Secondary IP address
            - system object identifier
            - gateway node flag (a flag which indicates whether the 
              node is configured to be a Gateway Node)

            Each node in a peer group has its own entry in the 
            database. 

            (b) The feeder information for each feeder in the peer group
            stored in the persistent topology database includes:

            - Routing node ID(local node ID)
            - A local port's 'ifIndex' which identifies the
              port the feeder is connected to on the routing
              node.
            - The feeder's 'shelf, slot, port' numbers which
              identifies the port on the feeder itself.
            - The protocol type that is used on the link.
            - The name of the feeder.
            - The LAN IP address of the feeder.
            - The ATM IP address of the feeder.
            - The model number of the feeder which identifies
              the type of the feeder.

            Each feeder in a peer group has its own entry in the 
            database. 

            (c) The link information for each node in the peer group 
            stored in the persistent topology database includes: 

            - local node's id, 
            - local node port's ifIndex and corresponding physical 
              descriptor 
            - remote node's id
            - remote node port's ifIndex and corresponding physical 
              descriptor  

            Each link in a peer group has its own entry in the 
            database. 

            The concept of peer groups is defined by 
            PNNI, and each peer group contains at least one node. 
            The persistent topology database only contains 
            nodal information for the nodes in a particular 
            peer group, because the Gateway Nodes extract the 
            nodal information from PNNI PTSEs, and the PTSEs  
            are flooded only within a peer group.  

            The persistent topology database is used by a management 
            station to discover the topology of the network 
            irrespective of the state and reachability of the
            nodes in that network.

            The information in the topology database will not 
            be deleted automatically. The information can only 
            be deleted by the network operator as an administrative 
            measure. This is to ensure that even if a node has gone 
            down, its information will still be in the topology 
            database until it is deleted by the network operator. 

            An outside link is a link that connects to a lowest-level
            outside node. In contrast to an inside link (i.e.,
            horizontal link) or an uplink, an outside link does not
            form part of the PNNI topology, and is therefore not used
            in path computation."

           built.       

           'disabling' indicates that this node is no longer the
           Gateway Node and is in the process of deleting the 
           topology database.

           'enabling' indicates that this node has been configured

           The management station should always poll this object
           first before taking action to: 

           a) 'enable' or 'disable' the Gateway Node 
           b) remove an entry or entries from 'cwtNodeInfoTable' and

           can 'disable' the Gateway Node if it desires.

           If the object returns 'enabling' or 'disabling', the
           management station should not take any actions. 

           If the object returns 'enabledAndFull', the management 
           station can take one of the following actions:

           a) remove enties from the cwtNodeInfoTable
           b) 'disable' and then 'enable' the Gateway Node, which
