Vlans; Spanning Tree Protocol (Stp); Port Mirroring - Avaya G250 Overview

VLANs

You can configure VLANs on:
In the G350, the fixed LAN port and the MM314 and MM316 ports
●
In the G250, all Ethernet ports except the WAN ETH port
●
Both the G250 and the G350 support up to eight VLANs. The following VLAN features are
supported:
VLAN port grouping. Port VLANs can be used to group LAN ports into logical groups.
●
Ingress VLAN Security. You configure a list of ingress VLANs on each port. Any packets
●
tagged 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 while
●
others 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 on
the MM314 and MM316 switched LAN ports.
Note:
STP is not supported in the G250.
Note:

Port mirroring

Both the G250 and the G350 support network traffic monitoring by port mirroring. You can
configure port mirroring on any LAN port. You implement port mirroring by connecting an
external traffic probe device to one of the LAN ports. The probe device monitors traffic that is
sent and received through other ports by copying the packets and sending them to the monitor
port.
Note:
You cannot configure port mirroring on the G350 fixed LAN port or the G250/
Note:
G350 WAN Fast Ethernet ports.
