Configuring the GbE Interconnect Switch using the Command Line Interface
Displaying Ingress Filtering Information
Use the following command to display the ingress filtering information on a per port basis:
Command Description
ingress-filter show
[port <portlist>]
Displays ingress filtering information for all ports
To display ingress information for a specified
port or ports, type port and the port number or
numbers.
This example shows the ingress filtering information for a series of ports.
Configuring Port Mirroring
The GbE Interconnect Switch allows you to copy frames transmitted and received on a port
(source) and redirect the copies to another port (target). You can attach a monitoring device
to the mirrored (target) port, such as a sniffer or an RMON probe, to view details about the
packets passing through the source port. This setting is useful for network monitoring and
troubleshooting purposes.
The following configuration rules apply to any port mirroring configuration:
•
•
•
•
•
•
A target mirror port cannot be configured as a trunk member.
VLAN configuration settings for any ports configured for mirroring cannot be changed.
The source and target ports should be members of the same VAN.
The direction of traffic on the source port can be one of the following:
Ingress traffic (received packets) on the source port
Egress traffic (transmitted packets) on the source port
Ingress and egress traffic on the source port
IMPORTANT: You cannot mirror a fast port onto a slower port. For example, if you try to mirror the
traffic from a 1000-Mb/s port onto a 100-Mb/s port, you can cause throughput problems. The port from
which you are copying frames must support an equal or lower speed than the port to which you are
sending the copies.
