5.6 Trunk
Trunking is used to expand bandwidth, for failover, and/or to increase error toler-
ance when networking multiple switches together.
All ports that are defi ned as members of the trunk group can be used for trunking
ONLY and cannot be used for other purposes, even when they are not being used
by the trunk group.
Cross-VLAN trunk grouping is not supported. All members of a trunk group must be
within the same VLAN. Otherwise the trunk will not function properly.
When the trunk group is used for inter-switch cascading (Uplinks), be sure the cas-
cading port used for connecting with the other switch is part of the corresponding
trunk group. The cascading of multiple ports (trunk members) must be done from
one trunk group to a corresponding trunk group.
CAUTION:
Never connect two trunk groups of a switch together or
cascade two switches through more than one trunk channel.
Such confi gurations will result in a network loop and will
cause a broadcast storm resulting in blocking of all network
traffi c on the switches.
