Modifying Dynamic Aggregate Partner Port Parameters
This section describes how to modify the following dynamic aggregate partner port parameters:
•Partner port system administrative state (see “Modifying the Partner Port System Administrative State”
on page 13-28)
•Partner port administrative key (see “Modifying the Partner Port Administrative Key” on page 13-30)
•Partner port system ID (see “Modifying the Partner Port System ID” on page13-30)
•Partner port system priority (see “Modifying the Partner Port System Priority” on page 13-31)
•Partner port administrative state (see “Modifying the Partner Port Administrative Status” on
page 13-32)
•Partner port priority (see “Modifying the Partner Port Priority” on page 13-32)
All of the commands to modify partner port parameters allow you to add the ethernet, fastethernet, and
gigaethernet keywords before the slot and port number to document the interface type or make the
command look consistent with early-generation Alcatel CLI syntax. However, these keywords do not
modify a port’s configuration. See Chapter 1, “Configuring Ethernet Ports,” for information on configur-
ing Ethernet ports.
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 Partner Port System Administrative State

The system administrative state of a dynamic aggregate group partner (i.e., remote switch) port is indi-
cated 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 lacp agg partner admin state command.

Configuring Partner Port System Administrative State Values

To configure the dynamic aggregate partner port’s system administrative state values by entering lacp agg,
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 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.
