Configuring Dynamic Link Aggregation Modifying Dynamic Link Aggregate Group Parameters
OmniSwitch AOS Release 8 Network Configuration Guide December 2017 page 9-20
Modifying the Partner Port System Administrative State
The system administrative state of a dynamic aggregate group partner ( remote switch) port is indicated by
bit settings in Link Aggregation Control Protocol Data Unit (LACPDU) frames sent by this 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 linkagg lacp agg partner admin-state command.
Configuring Partner Port System Administrative State Values
To configure the system administrative state values for the port on the dynamic aggregate partner, enter
linkagg lacp port, the slot number, a slash (/), the port number, partner admin-state, and one or more of
the keywords shown in the table below or none:
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 time-out is used for LACPDU frames. When this bit is disabled, a
long time-out 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 Specifies that bit 3 in the partner state octet is enabled. When this bit is
set, the port is allocated to the correct dynamic aggregation group. If
this bit is not enabled, the port is not allocated to the correct
aggregation group. By default, this value is disabled.
collect Specifying this keyword has no effect because the system always
determines 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
determines 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
determines its value. When this bit (bit 6) is set by the system, it
indicates that the partner is using defaulted actor information
administratively configured for the partner.
expire Specifying this keyword has no effect because the system always
determines its value. When this bit (bit 7) is set by the system, the actor
cannot receive LACPDU frames.
Note. Specifying none removes all administrative states from the LACPDU configuration. For example:
-> linkagg lacp port 7/49 partner admin-state none
