5.20 SmartTrunk AND THE CONFIGURATION SCREEN
Before discussing the SmartTrunk Configuration screen and how to use it,
it is necessary to understand what SmartTrunk is and the port connection
and configuration rules that must be followed. Refer to the SmartTrunk
User’s Guide, for basic information on SmartTrunking. For SmartTrunk
configuration rules, proceed to Section 5.20.1.
5.20.1 SmartTrunk Configuration Rules
The following rules must be followed when installing the DLE28-MA to
operate in a network configuration using SmartTrunking. These rules also
apply to other devices that support the SmartTrunk application.
1. Only ports designated as NETWORK ports, through Local or Remote
Management screens, will be considered for SmartTrunking.
2. All non-SmartTrunking interfaces MUST be designated as USER
ports.
3. A maximum of 12 ports may be used per instance, and there may only
be 8 instances per device.
4. If three or more devices are connected together for SmartTrunking,
then the ports that connect any of the two devices together MUST be
designated as USER ports to prevent a network loop condition. The
port with the least amount of bandwidth available would be the port(s)
that should be designated a “USER” port.
Refer to the list of supported features in the release notes to
determine if SmartTrunk is supported.
Failure to follow these rules will produce poor network
performance.
