This section describes how to mirror traffic from a source port to a target port.

port monitor

Use this command to configure a mirror session. Use the no form to clear a mirror session.

Syntax

port monitor interface [rx | tx | both]
no port monitor interface

• interface
  • ethernet unit/port
    • unit - This is device 1.
    • port - Port number.
• rx - Mirror received packets.
• tx - Mirror transmitted packets.
• both - Mirror both received and transmitted packets.

Default Setting

No mirror session is defined. When enabled, the default mirroring is for both received and transmitted packets.

Command Mode

Interface Configuration (Ethernet, destination port)

Command Usage

• You can mirror traffic from any source port to a destination port for real-time analysis. You can then attach a logic analyzer or RMON probe to the destination port and study the traffic crossing the source port in a completely unobtrusive manner.
• The destination port is set by specifying an Ethernet interface.
• When mirroring port traffic, the destination port must be included in the same VLAN as the source port. See VLAN Commands.
• Only one mirror session is allowed.

Example

The following example configures the switch to mirror all packets from port 5 to port 6:

(config)#interface ethernet 1/6 (config-if)#port monitor ethernet 1/5 both (config-if)#
