10 Configuring 802.1AB
Link Layer Discovery Protocol (LLDP) is an emerging standard that provides a solution for the
configuration issues caused by expanding networks. LLDP supports the network management software
used for complete network management. LLDP is implemented as per the IEEE 802.1AB standard. LLDP
specifically defines a standard method for Ethernet network devices and Media Endpoint Devices (MED)
to exchange information with its neighboring devices and maintain a database of the information. The
exchanged information, passed as LLDPDU, is in TLV (Type, Length, Value) format. The information
available to the network management software must be as new as possible; hence, remote device
information is periodically updated.
The LLDP-MED capability of OmniSwitch supports the usage of LLDP MED Network Policy to
advertise a VLAN to the connected MEDs.
In This Chapter
This chapter describes the basic components of 802.1AB and how to configure them through the
Command Line Interface (CLI). The CLI commands are used in the configuration examples; for more
details about the syntax of commands, see
