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.
destination interface { ethernet slot /[ QSFP-module/ ] port }
no destination interface { ethernet slot /[ QSFP-module/ ] port }
SPAN session configuration mode (config-monitor)
SPAN-on-Drop session configuration mode (config-span-on-drop)
SPAN-on-Latency session configuration mode (config-span-on-latency)
ERSPAN destination session configuration mode (config-erspan-dst)
Each local SPAN, SPAN-on-Drop, and ERSPAN 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, a VLAN, Host Interface (HIF), or a 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.
This example shows how to configure an Ethernet interface SPAN destination port and activate the SPAN session:
