Monitoring Point Cabling

The ports on an Enterprise Monitoring Point (EMP) are either “network connection ports” (used for connectivity to APM and for Delivery and Experience monitoring) or “Usage monitoring ports” (used for Usage monitoring). This page shows how to connect these port types to your network. To determine what each port on your Monitoring Point is used for, see the Port descriptions subsection (under Specifications)for your Monitoring Point.

Cabling for network connectivity

Network connection ports on Monitoring Points are used for connectivity to APM and for Delivery and Experience monitoring.

The following diagram shows the network connection port on the Monitoring Point (for example, Port 0 on an m70) connected to a switch on your network like other LAN clients. The network must provide connectivity to APM.

Cabling for Usage monitoring

Unlike Delivery and Experience monitoring, which initiate tests, Usage monitoring involves passively monitoring traffic. You typically want to monitor traffic at an aggregation point in the network. See Deployment Best Practices for more information on where to deploy your Monitoring Point for Usage monitoring.

There are two methods for physically connecting a Monitoring Point to your network for Usage monitoring: “out-of-band” and “inline”. The out-of-band method uses one port on the Monitoring Point. The inline method uses two.

Cabling for Usage monitoring - out-of-band

Out-of-band Usage monitoring requires that your switch is capable of port mirroring and that a mirror source and a mirror destination (also known as Switched Port Analyzer (SPAN) ports) have been configured. The switch’s mirror source port is the one being monitored (typically the aggregation point). The switch’s mirror destination port is connected to a Usage monitoring port (Out-of-band) on the Monitoring Point.

The following diagram shows how to cable a Monitoring Point for out-of-band Usage monitoring using its Usage monitoring port (Out-of-band) (for example, Port 2 on an m70).

Cabling for Usage monitoring - inline

Inline Usage monitoring involves using a pair of “bypass” ports (Usage monitoring ports (Inline)) to connect the Monitoring Point inline with the switch port being monitored (typically the aggregation point). The “uplink” port of the pair is connected upstream. The “downlink” port of the pair is connected to the uplink port on the switch. Traffic flows through the Monitoring Point from one of the bypass ports to the other. Traffic will continue to flow even if the Monitoring Point loses power.

The following diagram shows how to cable a Monitoring Point for inline Usage monitoring using its Usage monitoring ports (Inline) (for example, Port 2 (uplink) and Port 3 (downlink) on an m70).
