Cisco SwitchProbe devices are hardware devices with embedded firmware (specialized agent software) that collect a variety of statistical information about network operation. The SwitchProbe device collects this information by examining every packet passed on the network segment to which the agent is attached. The agent stores this statistical information locally within continuous counters that can be reset as desired.
These devices provide protocol monitoring and decoding when you use them with a client equipped with protocol decode software. All models also support the MIB II system and interface groups.
