LINK LAYER
DISCOVERY PROTOCOL
LLDP is used to discover basic information about neighboring devices
within the local broadcast domain. LLDP is a Layer 2 protocol that
advertises information about the sending device and collects information
gathered from neighboring network nodes it discovers.
Advertised information is represented in Type Length Value (TLV) format
according to the IEEE 802.1ab standard, and can include details such as
device identification, capabilities and configuration settings. Media
Endpoint Discovery (LLDP-MED) is an extension of LLDP intended for
managing endpoint devices such as Voice over IP phones and network
switches. The LLDP-MED TLVs advertise information such as network
policy, power, inventory, and device location details. The LLDP and LLDP-
MED information can be used by SNMP applications to simplify
troubleshooting, enhance network management, and maintain an accurate
network topology.
SYSTEM DEFAULTS
The switch’s system defaults are provided in the configuration file
“Factory_Default_Config.cfg.” To reset the switch defaults, this file should
be set as the startup configuration file.
The following table lists some of the basic system defaults.
