Mirroring Configurations

Using the Telnet Console

Incoming or outgoing traffic from any source port can be mirrored for real-time analysis. A logic analyzer or a RMON probe can then be attached to study the traffic crossing the source port in a completely unobtrusive manner. When mirroring port traffic, remember these conditions:

•The target port should be operating at the same or higher speed than the source port. If the target port is operating at a lower speed than the source port, packets will be lost.

•For optimum performance, you should mirror three or fewer ports at any given time.

To configure a port for mirroring

1.From the Main Menu, select Mirroring Configurations and press Enter.

2.Configure these fields.

Field		Description

	Specifies the port where information will be duplicated and sent for capture
Target Port	and network analysis. This is the port where a network analyzer would be
	attached to capture packets duplicated from the source (mirrored) port.

	Specifies which port to mirror and which packets to mirror. This port is the
	source of the packets. Use one of these values:
	•	R—Mirror incoming packet
Mirrored Port	•	T—Mirror outgoing packets
Mirrored Port	• B—Mirror both incoming and outgoing packets
	• B—Mirror both incoming and outgoing packets
	• - (none)—Do not mirror
	Use the spacebar to toggle these values for a specific port. If the port has an
	X, this port cannot be selected for mirroring.

3.Highlight APPLY and press Enter.

4.To modify a target port in the table of current settings, enter the port number in the Target Port field, change the mirror port value, highlight APPLY, and press Enter.

GMRP

GMRP (Group Multicast Registration Protocol) allows ports to dynamically join multicast groups. It provides a mechanism that allows bridges and end-stations to dynamically register (and subsequently, de-register) group membership information with the MAC bridge attached to the same LAN segment.

To configure GMRP globally

1.From the Main Menu, select GMRP and press Enter.

2.Use the spacebar to toggle the Switch GMRP field to Enabled or Disabled.

3.Highlight APPLY and press Enter.

To configure port GMRP settings

1. From the Main Menu, select GMRP and press Enter.
