LLDP

The SEFOS LLDP module is a portable software implementation of the LLDP. The module provides complete management capabilities using SNMP and CLI.

The SEFOS LLDP module conforms to IEEE 802.1AB-2005 standard. The LLDP allows systems on an Ethernet LAN to advertise their key capabilities and also to learn about the key capabilities of other systems on the same Ethernet LAN. This, in turn, promotes a unified network management view of the LAN topology and connectivity to aid network administration and trouble-shooting.

The SEFOS LLDP module provides the following features:

- Provides full conformance to the 802.1AB specification.

- Supports all mandatory TLVs (Chassis identifier, port identifier and time-to-live).

- Supports optional TLVs - port description, system name, system description, system capabilities and management address.

- Supports organizationally specific optional TLVs - port VLAN identifier, port and protocol VLAN identifier, VLAN name, MAC or PHY configuration or status, link aggregation and maximum frame size.

- Supports the basic MIB and the extension MIBs in Appendix F and Appendix G, defined in the 802.1AB specification and a proprietary MIB for management.

- Provides support for notifications through traps.
