Interpreting the Enterprise-Specific VLAN MIB

The enterprise-specific VLAN MIB for EX-series Ethernet switches, whose object identifier is {jnxExSwitching 5}, contains information about prestandard IEEE 802.10 VLANS and their association with LAN Emulation Clients (LAC). Devices with prestandard implementation maintain port groupings and associated filters that are used to form a virtual bridge.

The enterprise-specific VLAN MIB leverages the following objects and data types from standard MIBs, RFCs, and Juniper Networks enterprise-specific MIBs:

• Integer 32 and IpAddress–From SNMPv2–SMI
• MacAddress, DisplayString, and TruthValue–From SNMPv2–TC
• InterfaceIndex–From IF MIB
• InetAddress and InetAddressType–From Inet Address MIB
• jnxExVlan–From Juniper Networks enterprise-specific SMI MIB

For a downloadable version of this MIB, see www.juniper.net/techpubs/software/junos/junos92/swconfig-net-mgmt/mib-jnx-vlan.txt
