destination (SPAN session)
To configure a Switched Port Analyzer (SPAN) destination port, use the destination command. To
remove the destination SPAN port, use the no form of this command.

no source interface {ethernet slot/[QSFP-module/]port}
Syntax Description
Command Default None
Command Modes SPAN session configuration mode
Command History
Usage Guidelines Each local SPAN session destination session must have a destination port (also called a monitoring port)
that receives a copy of traffic from the source port.
The destination port can be any Ethernet physical port and must reside on the same switch as the source
port (for a local SPAN session). The destination port cannot be a source port, a port channel, or SAN
port channel group.
A destination port receives copies of sent and received traffic for all monitored source ports. If a
destination port is oversubscribed, it can become congested. This congestion can affect traffic
forwarding on one or more of the source ports.
Examples This example shows how to configure an Ethernet interface SPAN destination port and activate the SPAN
session:
switch# configure terminal
switch(config)# interface ethernet 1/5
switch(config-if)# switchport monitor
switch(config-if)# exit
switch(config)# monitor session 9 type local
switch(config-monitor)# description A Local SPAN session
switch(config-monitor)# source interface ethernet 1/1
interface Specifies the interface type to use as the destination SPAN port.
ethernet slot/[QSFP-module/]port Specifies the Ethernet interface to use as the destination SPAN
port. The slot number is from 1 to 255. The QSFP-module
number is from 1 to 4. The port number is from 1 to 128.
Note The QSFP-module number applies only to the QSFP+
Generic Expansion Module (GEM).
Release Modification
6.0(2)N1(1) Support for the QSFP+ GEM was added.
5.2(1)N1(1) This command was introduced.
