5.20SmartTrunk 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. Failure to follow these rules will produce poor network performance. Refer to Appendix D, About SmartTrunk, 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 DLE2X-MA and DLE3X-MA to operate in a network configuration using SmartTrunking. These rules also apply to other devices that support Cabletron Systems’ 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.

5.You cannot loop front panel ports back to the same standalone device. If the devices are modules residing in a chassis, then you cannot loop back to the same module in the same chassis or to different modules within that chassis. This includes all backplane interfaces that may display on the SmartTrunk Configuration screen.
