Configuring S-MLAG

Restrictions and guidelines
S-MLAG is intended for a non-IRF environment. Do not configure it on an IRF fabric. For more
formation about IRF, see Virtual Technologies Configuration Guide.
Each S-MLAG group can contain only one aggregate interface on each device.
The aggregate interfaces in an S-MLAG group cannot be used as DR interfaces or IPPs in DRNI. For
more information about DR interfaces and IPPs, see DRNI configuration in Layer 2—LAN Switching
Configuration Guide.
Do not configure the following settings on S-MLAG devices:
•
LACP MAD.
•
Link-aggregation traffic redirection.
•
Maximum or minimum number of Selected ports.
•
Automatic member port assignment.
As a best practice, maintain consistency across S-MLAG devices in service feature configuration.
Prerequisites
Configure the link aggregation settings other than S-MLAG settings on each S-MLAG device. Make
sure the settings are consistent across the S-MLAG devices.
Procedure
1. Enter system view.
system-view
2. Set the LACP system MAC address.
lacp system-mac mac-address
By default, the LACP system MAC address is the bridge MAC address of the device.
All S-MLAG devices must use the same LACP system MAC address.
3. Set the LACP system priority.
lacp system-priority priority
By default, the LACP system priority is 32768.
All S-MLAG devices must use the same LACP system priority.
4. Set the LACP system number.
lacp system-number number
By default, the LACP system number is not set.
You must assign a unique LACP system number to each S-MLAG device.
5. Enter Layer 2 aggregate interface view.

6. Set the link aggregation mode to dynamic.
link-aggregation mode dynamic
By default, an aggregation group operates in static mode.
