Assigning A Mirror Port And Monitor Ports - HP ProCurve 9304M Installation And Configuration Manual

2. Select the Advance link to display the following panel
.
3. Edit the value in the Chassis Poll Interval field to change polling interval. You can enter a value from 0 –
65535. The default is 60 seconds.
4. Click the Apply button to send the configuration change to the active module's running-config file.
5. If you want the change to remain in effect following the next system reload, select the Save link to save the
configuration change to the startup-config file.

Assigning a Mirror Port and Monitor Ports

You can monitor traffic on HP ports by configuring another port to "mirror" the traffic on the ports you want to
monitor. By attaching a protocol analyzer to the mirror port, you can observe the traffic on the monitored ports.
Monitoring traffic on a port is a two-step process:
• Enable a port to act as the mirror port. This is the port to which you connect your protocol analyzer.
• Enable monitoring on the ports you want to monitor.
You can monitor input traffic, output traffic, or both. Any port can operate as a mirror port and you can configure
more than one mirror port. You can configure up to 64 mirror ports. You can configure the mirror ports on different
modules and you can configure more than one mirror port on the same module.
Each mirror port can have its own set of monitored ports. For example, you can configure ports 1/1 and 5/1 as
mirror ports, and monitor ports 1/2 – 1/8 on port 1/1 and ports 5/2 – 5/8 on port 5/1. The mirror port and monitored
ports also can be on different slots.
Configuration Guidelines for Monitoring Inbound Traffic
Use the following considerations when configuring mirroring for inbound traffic on a Chassis device. The
guidelines are applicable whether you configure multiple mirror ports or just one mirror port.
• Configure only one mirror port to monitor input traffic on a given module. If you configure multiple mirror ports
on the same module, the inbound traffic for all the monitored ports on the module is sent to all the mirror ports
on the same module. For example, if you configure ports 1/1 and 1/13 as mirror ports, then enable monitoring
of inbound traffic on ports 1/2 and 1/14, the traffic from both ports is mirrored to both the mirror ports, 1/1 and
1/13. This occurs regardless of the mirror ports you assign to the monitor ports.
• When inbound traffic on a monitored port on one module is switched normally to another module, the
switched traffic will be mirrored to the mirror ports on the other module. For example, if inbound traffic on a
