Modifying Dynamic Link Aggregate Group Parameters Configuring Dynamic Link Aggregation
page 13-24 OmniSwitch 6600 Family Network Configuration Guide April 2006
Note. A port may belong to only one aggregate group. In addition, mobile ports cannot be aggregated. See
Chapter 7, “Assigning Ports to VLANs,” for more information on mobile ports.
Modifying the Actor Port System Administrative State
The system administrative state of a dynamic aggregate group actor port is indicated by bit settings in Link
Aggregation Control Protocol Data Unit (LACPDU) frames sent by the port. By default, bits 0 (indicating
that the port is active), 1 (indicating that short timeouts are used for LACPDU frames), and 2 (indicating
that this port is available for aggregation) are set in LACPDU frames.
The following subsections describe how to configure user-specified values and how to restore them to
their default values with the lacp agg actor admin state command.
Configuring Actor Port Administrative State Values
To configure an LACP actor port’s system administrative state values by entering lacp agg, the slot
number, a slash (/), the port number, actor admin state, and one or more of the keywords shown in the
table below or none:
lacp agg actor admin state
Keyword
Definition
active Specifies that bit 0 in LACPDU frames is set, which indicates that the
link is able to exchange LACPDU frames. By default, this bit is set.
timeout Specifies that bit 1 in LACPDU frames is set, which indicates that a
short timeout is used for LACPDU frames. When this bit is disabled, a
long timeout is used for LACPDU frames. By default, this bit is set.
aggregate Specifies that bit 2 in LACPDU frames is set, which indicates that the
system considers this link to be a potential candidate for aggregation. If
this bit is not set, the system considers the link to be individual (it can
only operate as a single link). By default, this bit is set.
synchronize Specifying this keyword has no effect because the system always deter-
mines its value. When this bit (bit 3) is set by the system, the port is
allocated to the correct dynamic aggregation group. If this bit is not set
by the system, the port is not allocated to the correct dynamic aggrega-
tion group.
collect Specifying this keyword has no effect because the system always deter-
mines its value. When this bit (bit 4) is set by the system, incoming
LACPDU frames are collected from the individual ports that make up
the dynamic aggregate group.
distribute Specifying this keyword has no effect because the system always deter-
mines its value. When this bit (bit 5) is set by the system, distributing
outgoing frames on the port is disabled.
default Specifying this keyword has no effect because the system always deter-
mines its value. When this bit (bit 6) is set by the system, it indicates
that the actor is using defaulted partner information administratively
configured for the partner.
