CISCO-VLAN-TRANSLATION-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.

VLAN translation refers to the ability of the device to translate between different virtual LANs or between VLAN and non-VLAN encapsulating interfaces at Layer 2. Translation is typically used for selective inter-VLAN switching of non-routable protocols and to extend a single VLAN topology across hybrid switching environments."

The translation is applied in both ingress and egress sides of all the Layer 2 trunks. VLAN translation makes the traffic arriving on the VLAN cvtGlobalOriginalVlan on the trunk ports to be mapped to or tagged with the VLAN cvtGlobalTranslatedVlan. It also causes all the traffic internally tagged with the VLAN cvtGlobalTranslatedVlan and leaving the trunk ports to be tagged with VLAN cvtGlobalOriginalVlan. A global VLAN translation configuration is inactive for those ports that are not Layer 2 trunks. The global VLAN translations are mutually exclusive to the port based VLAN translations. The rows in this table can only be created when the table cvtPortTranslationTable is empty. A conceptual row is created for each VLAN mapping configuration on the device which supports the feature. The value of cvtGlobalTranslationMax determines the maximum number of rows in this table." ::= { cvtGlobalTranslation 2 } cvtGlobalTranslationEntry OBJECT-TYPE SYNTAX CvtGlobalTranslationEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "Information about the VLAN translation for a particular VLAN to a different VLAN."
