CISCO-IETF-SCTP-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.

  cSctpCompliance MODULE-COMPLIANCE
    STATUS  current
    DESCRIPTION
       "The compliance statement for SNMPv3 entities which implement
       SCTP.
       As a remark, the not-accessible objects:
       cSctpAssocLocalAddressIPType and cSctpAssocRemAddressIPType do
       not support the dns(4)type since the use of the host names is
       limited to first stage, when the association is being
       established.
       cSctpAssocLocalAddressIP  and cSctpAssocRemAddressIP will only
       accept the size of 4 or 16 because it is only required to
       support IPv4 and unique IPv6 addresses."
