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={MACSRCMACDESTMACBOTHIPSRCIPDESTIPBOTH}]

[SPEED={10M100M1000M}]

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
