    SmartTrunk divides network traffic across multiple ports in parallel to provide additional throughput. The SmartTrunk application can be used with any of Cabletron Systems’ switch modules (except ATM modules). SmartTrunking A physical port configured in a SmartTrunk Group must: •...

  • Page 10: Packet Distribution

    Introduction Packet Distribution Packet distribution is based on hardware family type: SmartSwitch 6000 Packet distribution among the ports in the group is accomplished by adding the last two bytes of the destination and source MAC addresses and then applying the modulus operator to the sum using the number of active ports in the group.

  • Page 11: Compatibility - Dec Hunt Groups And Smartswitch Router (Ssr)

    Compatibility - DEC Hunt Groups and SmartSwitch Router (SSR) SmartTrunking for the SmartSwitch 6000 and the SmartSwitch 9000 is based on, and compatible with, DEC Hunt Groups. With the SSR adopting the DEC Hunt Groups protocol, this will allow all Cabletron equipment to be trunked to each other.

    Spanning Tree protocol. The SmartTrunk application only acknowledges its neighboring switches. If a user goes through several switch hops, then loops back to the first switch hop (creating a loop), a common connection between two switches (any two) will go into a Blocking state (see Figure 1-2).

    When this configuration is used, only one module’s SmartTrunk Group will be active. The second path will block and serve as a backup to the currently active NOTES path. (The active trunking path will be determined by the module providing the lowest path cost.) Refer to the release notes for image-specific restrictions while using SmartTrunking.

    NOTE Failure to follow these rules will produce poor network performance. 1. There is a limit of six (6) SmartTrunk groups per switch. There are no port number restrictions per group. 2. SmartTrunking ports should be configured to Full Duplex.
  • Page 18 SmartTrunk Configuration 7. Backplane ports (INB, FNB, FTM, etc.) on chassis-based switches cannot be configured as SmartTrunk ports and are not eligible to participate in trunking. 8. An end station plugged directly into a port configured for SmartTrunking will not be allowed to communicate. No traffic will flow into the port. 9.

    MIBII Logical Interface Behavior Logical/Virtual Port When a SmartSwitch creates a MIBII interface or logical port to represent the SmartTrunk group, other SmartSwitch features will work with the logical port. The only exception is RMON, which works on physical ports. NOTE Virtual and Logical refer to the same type of port.

The physical port’s VLAN information will remain unchanged, but never referenced. The user will need to add VLANs to the new logical port.
