Juniper Networks IDP75, IDP250 manual Peer Port Modulation, Management Ports, Console Serial Port

Chapter 2: Hardware Overview

Peer Port Modulation

After peer port modulation (PPM) is enabled, the sensor deactivates all the interfaces in that virtual router if the link goes down for any of the interfaces in a virtual router. All devices connected to the virtual router will detect a port failure and must be configured to take appropriate action.

You cannot enable NIC bypass and PPM on the same sensor. On the IDP 75, 250, 800, and 8200 sensors:

„PPM works on both copper and fiber interfaces.

„PPM works by turning off appropriate interfaces. Because of this, interface speeds can be set to auto on the sensor and on attached switches.

Management Ports

These ports are provided on all IDP sensors.

Console Serial Port

The console serial port provides access, using an RJ-45 connector, to the sensor’s command-line interface (CLI).

Management Port

The management port provides access to the ACM to the sensor through 10/100/1000 Mbps Ethernet. The ACM is accessed from the management port and entering the correct URL in a browser window (https://SensorIPAddress).

NOTE: Although both the console serial port and the management port use RJ-45 connectors, do not plug the network cable into the console serial port.

Hard Drives and USB Ports

Table 5 describes the hard drives and USB ports available on each sensor.
