The SHOW SWITCH PORT command displays the port speed and duplex
mode settings.
Port Trunking
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}]
DESTROY SWITCH TRUNK=trunk
Port trunk groups can only be destroyed on the switch if no ports belong to
them.
All the ports in a trunk group must belong to the same VLAN. Ports in a trunk
group can be added to other VLANs, either as individual ports or as an entire
group. A port in a trunk group cannot be deleted from any of the VLAN(s) to
