CISCO-VSI-CONTROLLER-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
    "This MIB module is used for configuring ATM Capable Switch 
     to be aware of VSI Controller information.

     Terminolgies used:

     VSI       - Virtual Switch Interface, a hardware-independent switch 
                 control protocol. This allows a Switch(node) to be 
		 controlled by a multiple controllers such as PNNI,LSC.
		 These control planes can be internal or external to the
	         switch.The VSI interface defines the messages and associated
	         functions which allow communication between the controller 
		 and the switch.This interface is expected to support all 
		 types of connections (voice,data,frame relay,ATM) for PVCs,
	         SPVCs and SVCs.

     VSI Master - software component which requests connections and receives
                  switch generic information. This controls one or more VSI 
                  Slaves. This may run on the switch or a dedicated controller
		  platform. This is the master module.It performs the interface
	 	  to the higher layer networking software and handles all VSI
		  related functions.
            
     VSI Slave - software component which converts generic connection
                 requests into hardware specific requests and hardware 
		 specific information into generic information.
		 This runs on the switch.a A centralized slave has a single
		 point of control for making connections and controlling 
		 interfaces, while a distributed slave allows for multiple
		 slaves to coexist on the same switch.

     Controller - Software ( and possibly hardware) which manages topology
                  and network resources and performs VSI Master fucntion. 
		  This performs source routing for ent-to-end SVCs, including
		  general call acceptance GCAC,setup calls with other 
		  controllers.
                  PNNI and MPLS are examples for the Controller.

     Controller Shelf - A controller shelf is a switch containing atleast
		   one VSI Controller which is controlling a different 
		   switch.It will also, typically, contain 'local' controllers
		   for itself."

CvcControllerShelfLocation ::= TEXTUAL-CONVENTION
    STATUS  current
    DESCRIPTION
        "The location of the Controller Shelf. 

	 internal(1)  - controller resides on the same shelf
	                as the switch.
	 external(2)  - controller resides on the external 
		        platform. The controller shelf is
		        connected to the switch by an ATM link."

CvcControllerType ::= TEXTUAL-CONVENTION
    STATUS  current
    DESCRIPTION
        "The type of the controller which is a VSI Master.
	 The Possible values are :
	     
	 par(1) -  Portable Auto Route(PAR). This is a VSI Master controller
	           implementing Cisco Proprietary protocol for network
	           routing and topology in a Network containing only 
		   Cisco Switches.

	 pnni(2) - Private Network-to-Network Interface (PNNI) controller.
		   The PNNI protocol is used between private ATM Switches
		   and between groups of ATM switches. This protocol is 
		   defined for distributing topology information between
		   switches and clusters of switches.

	 lsc(3)  - Label Switch Controller(TSC).The LSC Implements MPLS
	           (Multi Protocol Label Switching) protocol. The LSC is 
		   a router which is capable of controlling the operation
		   of a separate ATM switch so that the two of them 
                   together function as a single ATM-LSR(ATM Label Switch
                   Router).
		   The LSC controls the operation of the ATM Switch
		   using a 'Switch Control Protocol', which allows the
		   LSC to setup and remove cross-connects on the ATM
		   switch, to discover the configuration and capabilities
		   of the controlled switch, and to gather statistics from
		   the controlled switch."
