Overview of the Avaya G350 Media Gateway - Avaya Support

Summary of servicesVLANsYou can configure VLANs on the G350’s fixed LAN port and on the MM314 ports. The G350supports up to eight VLANs.The following VLAN features are supported:● VLAN port grouping. Up to 15 port VLANs can be used to group LAN ports into logicalgroups.●●●Ingress VLAN Security. You configure a list of ingress VLANs on each port. Any packetstagged with an unlisted VLAN are dropped when received on the port.Class of Service (CoS) tagging. Packets are tagged with VLANs per CoS.Inter-VLAN routing. You can configure specific VLANs to permit access to the WAN whileothers can be configured to deny access to the WAN.Spanning Tree Protocol (STP)The IEEE 802.1D (STP) and IEEE 802.1w (RSTP) Spanning Tree Protocols are supported onthe MM314 switched LAN ports.Port mirroringThe G350 supports network traffic monitoring by port mirroring. You can configure port mirroringon any LAN port. You implement port mirroring by connecting an external traffic probe device toone of the LAN ports. The probe device monitors traffic that is sent and received through otherports by copying the packets and sending them to the monitor port. Port mirroring is onlysupported on the 24 Fast Ethernet ports on the MM314 media module.Port redundancyYou can configure port redundancy on the G350. Port redundancy allows you to provide both aprimary link and a backup link to an important resource. Port redundancy is supported betweenany two PoE ports on the MM314 media module.36 Overview of the Avaya G350 Media Gateway
