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 […]

redundancy protocols VRRP (Virtual Router Redundancy Protocol), protocols for redundancy

VRRP(Virtual Router Redundancy Protocol) VRRP(Virtual Router Redundancy Protocol) is a standard based redundancy protocol. The configuration of this protocol is like HSRP with only small differences. In VRRP the active router is called Master, and the remainning ones are all Backup routers. So there can be multiple backup routers. VRRP (Virtual Router Redundancy Protocol) By […]

network redundancy, protocols for redundancy

Network Redundancy Protocols Redundancy is a common point for today’s topologies. Especially in mission-critical networks it is not acceptible that using only one gateway to reach a point. Because one gateway means single point of failure. With multiple gateways, you can still reach the remote node even if the gateway that you connect fails. As […]

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 […]
