Link Layer Discovery Protocol-Media Endpoint Discovery, LLDP-MED

LLDP-MED (Link Layer Discovery Protocol-Media Endpoint Discovery) As a standard and open protocol, LLDP is a good protocol. After the development of LLDP, some of the additional properties needed especially for Voice Over IP (VoIP). So LLDP extended. The extended version of LLDP is LLDP-MED (Link Layer Discovery Protocol – Media Endpoint Discovery). You can […]

How LLDP Works, LLDP Mechanism

LLDP (Link Layer Discovery Protocol) LLDP (Link Layer Discovery Protocol) is a Standard Neighbour Discovery Protocol that is used by all vendors. Like all other Neighbour Discovery Protocols, LLDP works on Layer 2 (Data-link Layer). By using LLDP, directly connected neighbours are discovered. To discover a neighbour device, LLDP must be enabled both on the […]

Neighbour Discovery Protocols Neigbour Discovery Protocols provides directly connected devices to discover and collect information about each other. Network devices can provide directly connected neighbour device’s identification, configuration and any capabilities. Neighbour Discovery Protocols work on Layer 2. There are different neighbour protocols for different vendors. Generally they are refer this protocol like “vendor” discovery […]

vlan frame tagging protocols, ISL and Dot1q

DTP (Dynamic Trunking Protocol) and VLAN Frame Tagging Protocols (ISL and dot1.q) LAN Frame Tagging Protocols (ISL and dot1.q) There are two types of frame tagging protocols. These are : – ISL(Inter-Switch Link) – dot1Q (or IEEE 802.1Q) These protocols can be configured manually or negotiated by DTP(Dynamic Trunking Protocol). DTP is a Cisco proprietary […]

vlan(virtual local area network) port assignment

VLAN Port Assignment VLANs can be assigned statically and dynamically. Static configuration is more common, but dynamic is also used. Static VLAN assignment is like its name. You will statically assign the ports to the VLAN. Dynamic VLAN assignment can be done by VLAN Membership Policy Server(VMPS). VMPS needs VLAN-MAC address relationship database. Here, we […]
