It is not enough for the monitor service to monitor a port that all voice traffic goes
through, such as the Ethernet port to which a gateway to the PSTN is connected. The
monitor service must monitor the Ethernet ports that the IP phones are directly
connected to. This is because MAC addresses change as packets pass through OSI
Layer 3 devices (e.g. routers).

Layer 3 devices (e.g. routers).
Cisco Unified Mobile Agent monitoring requires a monitor service to be configured for
each agent gateway. This is done by enabling SPAN-based monitoring for that gateway,
as well as entering the agent gateway IP address and monitor service mapping in
Cisco Desktop Administrator.

The monitor service sniffs packets on a single NIC (network interface card), and
therefore a single Ethernet port. This port needs to be configured to monitor the
Ethernet ports of all agent IP phones. This does not necessarily require that the
monitor service and all agent IP phones be connected to the same network switch.
That depends on the monitoring capabilities of the network switch.

NOTE: The VoIP Monitor Service does not support hubs.
Cisco Catalyst switches use SPAN (switched port analyzer) to monitor ports. Some of
the capabilities and restrictions of Catalyst switches are:

A monitor port cannot be in a Fast EtherChannel or Gigabit EtherChannel port
group.
group.
■
A monitor port cannot be enabled for port security.
■
A monitor port cannot be a multi-VLAN port.
■
A monitor port must be a member of the same VLAN as the port monitored.
VLAN membership changes are disallowed on monitor ports and ports being
monitored.

■
A monitor port cannot be a dynamic-access port or a trunk port. However, a
static-access port can monitor a VLAN on a trunk, a multi-VLAN, or a
dynamic-access port. The VLAN monitored is the one associated with the
static-access port.

Catalyst 4000, 5000, and 6000 Series Switches
■
You can monitor ports belonging to multiple VLANS on these switches.
■
The Catalyst 6000 with CatOS 5.3 or higher has a feature called Remote
SPAN (RSPAN) which allows you to monitor ports spread over a switched
network. With RSPAN on a Catalyst 6000, the monitor service and IP phones
can be on separate switches.
