CISCO-WLAN-VLAN-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.

A value of 0 indicates NULL or no VLAN ID. This textual convention is used instead of VlanId defined in Q-BRIDGE-MIB of RFC 2674 because value 0 and 4095 is not permitted.

The dot1qPvid specifies the native VLAN ID on each device interface. If this object is '0', the return value of dot1qPvid is not valid. If the device is attached to a VLAN port of an Ethernet bridge or switch, then the device must have a non-zero native VLAN ID, and that VLAN ID must also match the VLAN ID of the port on the bridge or switch.
