RSPAN
The RSPAN feature is not supported on all switch models.
Because switches have a limited number of physical ports to which IP phones and
computers can attach, most networks contain multiple switches. These switches are
interconnected, either directly or through routers and gateways, to create the network.
The Cisco monitoring and recording software that runs on the server can only capture
from a single NIC adapter, so if more IP phones are desired as network sources than
there are ports on the switch, you can either add another monitoring server attached
to another switch where the phones are connected, or you can use the Remote
Switched Port Analyzer (RSPAN) feature found on some Cisco Catalyst switches.

This is a quite common scenario in real-world Cisco software deployments. Customers
do not like to change their network infrastructure to satisfy software applications. The
software must be able to handle the network configuration.

An RSPAN configuration allows ports on different switches to be configured as source
ports and delivered to a single destination port. The switches are connected to each
other and network traffic from all the ports is sent to the switch with the destination
port.

, we have a customer who has three network switches that are connected
to each other. Agent phones are connected to all three switches and we want to be
able to record their calls. If we assume that all the switches support RSPAN, we can
configure an RSPAN VLAN and assign the ports on all the switches that have agent
phones attached to this VLAN. On the switch with the Cisco monitoring server
attached, we create a SPAN session that uses the RSPAN VLAN as the source and use
the Cisco monitoring server port as the destination port. All voice traffic from the
phones on all the switches is sent to the destination port where the audio streams
can be separated, processed, and saved or forwarded to another PC for reviewing.
