Voice VLAN

Image
The voice VLAN feature is provided to separate voice traffic from data traffic and assign higher priority to voice traffic, thus decreasing voice transmission delay and jitter. You can assign or remove a port to or from the voice VLAN manually or have the switch do that dynamically by configuring the automatic voice VLAN assignment mode on the port. On a port configured with the automatic voice VLAN assignment mode, the switch automatically assigns the port to the voice VLAN when receiving a packet with the source MAC address matching a recognizable voice device vendor OUI. As soon as the port is assigned to the voice VLAN, an aging timer starts. If no recognizable voice traffic has been received before the timer expires, the port is removed from the voice VLAN.

Multiple VLAN Registration Protocol (MVRP) (GVRP)

Multiple VLAN Registration Protocol  ( MVRP ) formerly known as  GARP VLAN Registration Protocol  ( GVRP ) or Generic VLAN Registration Protocol  is a standards-based Layer 2 network protocol, for automatic configuration of VLAN information on switches. It was defined in the 802.1ak amendment to 802.1Q-2005. Within a layer 2 network, MVRP provides a method to dynamically share VLAN information and configure the needed VLANs. In Other Words M VRP enables a switch to propagate local VLAN registration information to other participant switches and dynamically update the VLAN registration information from other switches to its local database about active VLAN members and through which port they can be reached. GVRP ensures that all switches on a bridged LAN maintain the same VLAN registration information, while less manual configuration workload is involved.
