Set the short LACP timeout
interval (3 seconds) for the
interface.
lacp period short
By default, the long LACP timeout
interval (90 seconds) is used by
the interface.
To avoid traffic interruption during
an ISSU, do not set the short
LACP timeout interval before
performing the ISSU. For more

Configuring an aggregate interface
Most configurations that can be made on Layer 2 or Layer 3 Ethernet interfaces can also be made on
Layer 2 or Layer 3 aggregate interfaces.
Configuring the description of an aggregate interface
You can configure the description of an aggregate interface for administration purposes, for example,
describing the purpose of the interface.
To configure the description of an aggregate interface:

Setting the MAC address for an aggregate interface
Typically, all aggregate interfaces on a device use the same MAC address, and aggregate interfaces
on different devices use different MAC addresses. However, you must set different MAC addresses
for aggregate interfaces on a device in some situations.
For example, in a spanning tree network, the BPDUs sent by Layer 2 aggregate interfaces on a
device have the same source MAC address. When the device communicates with a third-party
device, these BPDUs are considered attack packets and are dropped by the third-party device. To
solve this problem, set different MAC addresses for the Layer 2 aggregate interfaces.
To set the MAC address for an aggregate interface:
