For example, you can configure ports e 2/4, 2/6, and 2/7 (excluding e 2/5) together on a module as a trunk group. This feature is supported on static and LACP trunk ports, as well as GbE and 10-GbE ports. Flexible trunk ports follow the same rules as listed in "Trunk group rules" on page 395. NOTE For PowerConnect B-Series FCXPowerConnect B-Series FCXdevices only, this feature is supported from Web Management, but not from SNMP. For all other PowerConnect devices, this feature is not supported from SNMP or Web management. For configuration details, see "CLI syntax for configuring non-consecutive ports in a trunk group" on page 401. Trunk group load sharing Dell PowerConnect devices load-share across the ports in the trunk group. The method used for the load sharing depends on the device type and traffic type (Layer 2 or Layer 3). NOTE Layer 2 and Layer 3 AppleTalk traffic is not load-balanced. Layer 3 routed IP or IPX traffic also is not load balanced. These traffic types will however still be forwarded on the trunk ports. Support for IPv6 Dell PowerConnect devices that support IPv6 take the IPv6 address for a packet into account when sharing traffic across a trunk group. The load sharing is performed in the same way it is for IPv4 addresses; that is; trunk types whose traffic load is shared based on IPv4 address information can now use IPv6 addresses to make the load sharing decision. Load sharing occurs as described in Table 72. 398 PowerConnect B-Series FCX Configuration Guide 53-1002266-01
