Support for flexible trunk group membership

PowerConnect devices support flexible trunk group membership, which eliminates the
requirement for port membership to be consecutive, and allows the trunking of ports on
non-consecutive interfaces. 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"
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
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
