which speed and mode to use. Autonegotiation allows the ports to adjust their 
speed and duplex mode to accommodate the devices connected to them. Each 
switch port can be either configured with a fixed speed and duplex mode, or 
configured to autonegotiate speed and duplex mode with a device connected 
to it to determine a speed and mode that will allow successful transmission. An 
autonegotiating port will adopt the speed and duplex mode required by 
devices connected to it. If another autonegotiating device is connected to the 
switch, they will negotiate the highest possible common speed and duplex 
mode (Table 4). Setting the port to a fixed speed and duplex mode allows it to 
support equipment that cannot autonegotiate. Switch ports will autonegotiate 
by default when they are connected to a new device. To change this setting, use 
the command:

SET SWITCH PORT={port-list|ALL} 

SPEED={AUTONEGOTIATE|10MHALF|10MFULL|100MHALF|100MFULL|10

00MHALF|1000MFULL}

Autonegotiation can also be activated at any time after this, on any port that is 
set to autonegotiate, by using the command:

ACTIVATE SWITCH PORT={port-list|ALL} AUTONEGOTIATE 

On the first switch, the gigabit uplink ports always use 1000 Mbps speed and 
operate in full duplex mode, but these ports can also autonegotiate with peers 
in order to successfully pass the negotiation phase to get to successful 
operation.

 

The SHOW SWITCH PORT command displays the port speed and duplex 
mode settings.

Port trunking, also known as port bundling or link aggregation, allows a 
number of ports to be configured to join together to make a single logical 
connection of higher bandwidth. This can be used where a higher performance 
link is required, and makes links even more reliable. 

The switch supports up to 6 trunk groups, of up to 8 switch ports each. The two 
gigabit Ethernet ports can also be grouped together to form a trunk group. It is 
not possible for a trunk group to include both 10/100 Ethernet and gigabit 
Ethernet ports. Ports in the trunk group do not have to be contiguous. Port 
trunking is supported between AR800 Series and Rapier switches, and may be 
compatible with trunking algorithms on third party devices.

Port trunk groups are created and destroyed on the switch using the 
commands:

CREATE SWITCH TRUNK=trunk [PORT=port-list] 

[SELECT={MACSRC|MACDEST|MACBOTH|IPSRC|IPDEST|IPBOTH}] 

[SPEED={10M|100M|1000M}]

100 Mbps, Full duplex

1000Mbps Full duplex

100 Mbps, Half duplex

10Mbps, Full duplex
