NETGEAR 8800 Chassis Switch CLI Manual egress ingress-and-egress Specifies packets be mirrored as they are sent from a port. Specifies all forwarded packets be mirrored. This is the default setting on the NETGEAR 8800 series switches for port-based mirroring. Default N/A. Usage Guidelines You must enable port-mirroring using the enable mirroring to port command before you can configure the mirroring filter definitions. Port mirroring configures the switch to copy all traffic associated with one or more ports to a monitor port on the switch. The switch uses a traffic filter that copies a group of traffic to the monitor port. Up to 16 mirroring filters and one monitor port can be configured on the switch. Frames that contain errors are not mirrored. Guidelines for configuring mirroring This section summarizes the guidelines for configuring mirroring: • When you disable mirroring, all the filters are unconfigured. • You cannot mirror the monitor port. • The mirroring configuration is removed when you: • Delete a VLAN (for all VLAN-based filters). • Delete a port from a VLAN (for all VLAN-, port-based filters). • Unconfigure a slot (for all port-based filters on that slot). • Any mirrored port can also be enabled for load sharing (or link aggregation); however, each individual port of the load-sharing group must be explicitly configured for mirroring. • The mirroring filters are not confined to a single module; they can have ports that span multiple modules. • You cannot use the management port at all in mirroring configurations. • You cannot run ELSM and mirroring on the same port. If you attempt to enable mirroring on a port that is already enabled for ELSM, the switch returns a message similar to the following: Error: Port mirroring cannot be enabled on an ELSM enabled port. The traffic filter can be defined based on one of the following criteria: • Physical port-All data that traverses the port, regardless of VLAN configuration, is copied to the monitor port(s). You can specify which traffic the port mirrors: • Ingress-Mirrors traffic received at the port. • Egress-Mirrors traffic sent from the port. Chapter 5.
