NETGEAR 8800 Chassis Switch CLI Manual Example The following command enables MAC address learning on slot 1, ports 7 and 8: enable learning ports 1:7-8 enable mirroring to port enable mirroring to [port | port-list loopback-port ] {remote-tag } Description Dedicates a port on the switch to be the mirror output port, or the monitor port. Syntax Description port port-list loopback-port port remote-tag Specifies the mirror output port. Specifies the list of ports where traffic is to be mirrored. Specifies an otherwise unused port required when mirroring to a port-list. The loopback-port is not available for switching user data traffic. Specifies a single loopback port that is used internally to provide this feature. Specifies the value of the VLAN ID used by the mirrored packets when egressing the monitor port. Default Disabled. Usage Guidelines Port mirroring configures the switch to copy all traffic associated with one or more ports, VLANS or virtual ports. A virtual port is a combination of a VLAN and a port. The monitor port(s) can be connected to a network analyzer or RMON probe for packet analysis. 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. After a port has been specified as a monitor port, it cannot be used for any other function. Frames that contain errors are not mirrored. 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 on NETGEAR 8800 series switches 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. You can specify which traffic the port mirrors: 226 | Chapter 5. Commands for Configuring Slots and Ports on a Switch

Commands for Configuring Slots and Ports on a Switch

NETGEAR 8800 Chassis Switch CLI Manual

Example

The following command enables MAC address learning on slot 1, ports 7 and 8:

enable learning ports 1:7-8

enable mirroring to port

enable mirroring to [port <port> | port-list <port-list> loopback-port <port> ] {remote-tag

<vlan tag>}

Description

Dedicates a port on the switch to be the mirror output port, or the monitor port.

Syntax Description

Default

Disabled.

Usage Guidelines

Port mirroring configures the switch to copy all traffic associated with one or more ports,

VLANS or virtual ports. A virtual port is a combination of a VLAN and a port. The monitor

port(s) can be connected to a network analyzer or RMON probe for packet analysis. 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. After a port

has been specified as a monitor port, it cannot be used for any other function. Frames that

contain errors are not mirrored.

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 on NETGEAR 8800 series switches 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. You can specify which traffic the port mirrors:

port

Specifies the mirror output port.

port-list

Specifies the list of ports where traffic is to be mirrored.

loopback-port

Specifies an otherwise unused port required when mirroring to a port-list. The

loopback-port is not available for switching user data traffic.

port

Specifies a single loopback port that is used internally to provide this feature.

remote-tag

Specifies the value of the VLAN ID used by the mirrored packets when

egressing the monitor port.
