NETGEAR 8800 User Manual
Enabling and Disabling Switch Ports
By default, all ports are enabled. To enable or disable one or more ports on a switch, use the
following commands:
enable port [<port_list> | all]
disable port [<port_list> | all]
For example, to disable slot 7, ports 3, 5, and 12 through 15 on a modular switch, use the
following command:
disable port 7:3,7:5,7:12-7:15
You have the flexibility to receive or not to receive SNMP trap messages when a port
transitions between up and down. To receive these SNMP trap messages, use the following
command:
enable snmp traps port-up-down ports [<port_list> | all]
To stop receiving these messages, use the following command:
disable snmp traps port-up-down ports [<port_list> | all]

Configuring Switch Port Speed and Duplex Setting
Note: For information on displaying port speed, duplex, autonegotiation,
and flow control settings, see
Displaying Port Information on
page 148.
XCM8800 supports the following port types:
• 10 Gbps ports
• 10/100/1000 Mbps copper ports
• 10/100/1000 Mbps copper ports with Power over Ethernet (PoE)—only on the XCM8848T
with XCM88P installed
• 1 Gbps small form factor pluggable (SFP) gigabit Ethernet interface converter (GBIC)
fiber ports
Autonegotiation determines the port speed and duplex setting for each port (except 10 Gbps
ports). You can manually configure the duplex setting and the speed of 10/100/1000 Mbps
ports.
The 10/100/1000 Mbps ports can connect to either 10BASE-T, 100BASE-T, or 1000BASE-T
networks. By default, the ports autonegotiate port speed. You can also configure each port
for a particular speed (either 10 Mbps or 100 Mbps).
