When configuring trunk groups, consider the following:
•
When adding or removing port(s), the following message appears:
Enter Port Number(s) or Range of Port(s)
You can enter individual ports, separated by a comma, or a range of
ports separated by a hyphen.
•
Protocol Enable either enables or disables a proprietary Cabletron
protocol to be run by the switch for purposes of automatically
establishing and maintaining a trunk.
If the protocol is enabled, the switch uses the proprietary DEC Hunt
Group protocol to detect when multiple links are established between
two devices, and then automatically set up a trunk. Normally,
Spanning Tree would detect multiple links, and block all but one.
However, with trunking, multiple paths are valid. Protocols should be
enabled when connecting the SmartSTACK switch to other
Cabletron devices, or any other devices using the DEC Hunt Group
protocol.
If the protocol is disabled, trunks should be manually configured
using the user interface, SNMP, or web access.
