Switching Introduction

Activating and Deactivating Switch Ports

An active switch port is one that is available for packet reception and transmission. Disabling a
switch port does not affect the STP operation on the port. By default ports and VLANs are
activated. To shutdown a port or VLAN use the
the no-shutdown command to reactivate it.

Autonegotiation

Autonegotiation lets the port adjust its speed and duplex mode to accommodate the device
connected to it. When the port connects to another autonegotiating device, they negotiate the
highest possible speed and duplex mode for both of them.
By default, all ports autonegotiate. Setting the port to a fixed speed and duplex mode may be
necessary when connecting to a device that cannot autonegotiate.

Duplex mode

Ports can operate in full duplex or half duplex mode depending on the type of port it is. When
in full duplex mode, a port transmits and receives data simultaneously. When in half duplex
mode, the port transmits or receives but not both at the same time.
You can set a port to use either of these options, or allow it to autonegotiate the duplex mode
with the device at the other end of the link.
To configure the duplex mode
awplus#configure terminal
awplus(config-if)#interface port1.0.1
awplus(config-if)#duplex (auto|full|half|

Speed options

Before configuring a port's speed, check the hardware limit for the particular port type. The
following list can be used as a guide:

You can set a port to use one of these speed options, or allow it to autonegotiate the speed
with the device at the other end of the link.
Most types of switch port can operate in either full duplex or half duplex mode. In full duplex
mode a port can transmit and receive data simultaneously. In half duplex mode the port can
either transmit or receive, but not at the same time.
