Chapter 6: Static Port Trunking
102
 A port can belong to only one static trunk at a time.
 The ports of a static trunk can be configured to be
members of more than one VLAN.
 The ports of a static trunk can be either untagged or
untagged members of the same VLAN.
The switch selects a port in the trunk to handle broadcast packets and
packets of unknown destination. The switch makes this choice based on a
hash algorithm, depending upon the source and destination MAC
addresses.
