5. Commands for Configuring Slots and Ports on a Switch 5 This chapter describes commands related to: • Enabling, disabling, and configuring individual ports • Configuring port speed (Fast Ethernet ports only) and half- or full-duplex mode • Creating link aggregation groups on multiple ports • Displaying port statistics • Configuring mirroring • Configuring software-controlled redundant ports and Smart Redundancy By default, all ports on the switch are enabled. After you configure the ports to your specific needs, you can select which ports are enabled or disabled. Fast Ethernet ports can connect to either 10BASE-T or 100BASE-T networks. By default, the ports autonegotiate (automatically determine) the port speed. You can also configure each port for a particular speed (either 10 Mbps or 100 Mbps). In general Gigabit Ethernet ports with fiber interfaces are statically set, and their speed cannot be modified. The switch comes configured to use autonegotiation to determine the port speed and duplex setting for each port. You can manually configure the duplex setting and the speed of 10/100 Mbps ports, and you can manually configure the duplex setting on gigabit Ethernet ports. All ports on the switch (except gigabit Ethernet ports) can be configured for half-duplex or full-duplex operation. The ports are configured to autonegotiate the duplex setting, but you can manually configure the duplex setting for your specific needs. Flow control is supported only on gigabit Ethernet ports. It is enabled or disabled as part of autonegotiation. If autonegotiation is set to off, flow control is disabled. When autonegotiation is turned on, flow control is enabled. (See the NETGEAR 8800 User Manual for more detailed information on flow control on NETGEAR devices.) Link aggregation, or load sharing, with NETGEAR switches allows you to increase bandwidth and resilience between switches by using a group of ports to carry traffic in parallel between switches. The sharing algorithm allows the switch to use multiple ports as a single logical port. For example, VLANs see the link aggregation group (LAG) as a single logical port. The algorithm also guarantees packet sequencing between clients. NETGEAR 8800 software supports two broad categories of load sharing, or link aggregation: static load sharing and dynamic load sharing. Chapter 5.
