Parameter Description
Port Priority
Defines if this port is more or less likely to become the root port.
The range is from 0 to 255, the default setting is 128
The lower number has the highest priority.
Path Cost
Specifies the path cost of the port. The switch uses this parameter
to help determine which port will become a forwarding port.
Lower numbers will be used as forwarding ports first.
The range is from 1 to 65535. The default values based on
IEEE802.1D are: 10Mb/s = 50-600, 100Mb/s = 10-60, 1000Mb/s =

2.4.9 Port Sniffer (Port Mirroring)
The Port Sniffer is used to monitor traffic in a switched network. Traffic passed
through ports can be monitored by one specific port. i.e. Traffic inbound or outbound
on a monitored port will be duplicated into the configured sniffer port.
1. Sniffer Mode: Selects sniffer mode: Disable/Rx/Tx/Both.
2. Analysis Port: Use this option to select the destination port for monitored traffic.
This is the port that your network analyser would be connected to.
