Page 25: Chapter 4: Troubleshooting Tools
This section describes available troubleshooting tools and their applications. Port mirroring Avaya Ethernet Routing Switch 4000 Series switches have a port mirroring feature that helps you to monitor and analyze network traffic. The port mirroring feature supports both ingress (incoming traffic) and egress (outgoing traffic) port mirroring. After port mirroring is enabled, the ingress or egress packets of the mirrored (source) port are forwarded normally and a copy of the packets is sent from the mirrored port to the mirroring (destination) port.
Page 26: Port Mirroring Commands
Port mirroring commands See Configuring System Monitoring on Avaya Ethernet Routing Switch 4000 Series, NN47205-502 for port mirroring command information. Use the port mirroring commands to assist in diagnostics and information gathering.
