Migration From A Pre-02.6.00 Trunk Or Lacp Configuration - Dell PowerConnect B-RX Configuration Manual

The device switch uses the hash index in the following formula, using the modulo operator (written
as "%" in C programming language).
(hash index)% (Number of trunk ports in a trunk group) = selected trunk port

Migration from a pre-02.6.00 trunk or LACP configuration

if you are upgrading from a version of the Multi-Service IronWare software prior to 02.6.00 and
have either Trunks or LACP configured, the previous configuration will be automatically updated
with the new commands to form an LAG that is equivalent to the previous configuration. To
accomplish this, the old trunk and link-aggregation commands are maintained during startup
configuration parsing, but disabled during normal configurations.
The following process is followed during the conversion of the trunk and link-aggregation to the new
LAG commands.
1. For any static trunk configured using the trunk ethernet <slot/port> to <slot/port> command,
2. For any dynamic link aggregation (LACP) group configured using the port-level link-aggregate

the following conversion procedure is followed.
a. A static LAG is created containing the port list specified in the trunk command. This LAG is
then automatically deployed.
b. The lowest-numbered port from the original trunk list is selected as the primary port of the
LAG.
c. Any trunk config-trunk-ind command, such as port name, is converted to the
corresponding LAG commands.
d. The default load balancing scheme previously known as server is converted to the default
hash-based load balancing scheme.
e. The converted LAG is named "LAG_x", where "x" is a unique number assigned by the
system starting from 1.
