4.1
Link Aggregation Support
Supermicro switches support both static and dynamic link aggregations. Dynamic link aggregation support
is based on the Link Aggregation Control Protocol (LACP).
Supermicro switches support only Layer 2 level link aggregation. Hence, only switching ports can be
aggregated.
Supermicro switches do not support the Multiple Chassis Link Aggregation (MLAG) feature
4.2
Link Aggregation Numbers
Supermicro switches support up to 52 port channels.
Each port channel can have eight active links.
Users can configure more than eight ports to a LACP mode port channel. However, a
maximum of eight ports only can be in an active bundle state in any port channel.
4.3
Link Aggregation Defaults
The Link Aggregation feature is enabled by default in Supermicro switches.
When a port channel interface is created, it will be added to VLAN 1 by default.
Port channels use the MAC address of the first physical link added to it.
The default LACP system priority is 32768.
The default LACP port priority is 128.
The default LACP timeout is long (30 seconds).
The default LACP wait time is 2 seconds.
4.4
Static Link Aggregation
Supermicro switches support static link aggregation.
User can add up to eight ports to a static port channel group. When the physical link status of one or
more ports in a channel group is up, that port channel status will be up. The port channel status will be
down when the ports physical link status of all members are down.
Switches do not exchange any port channel control information with other end devices in static link
aggregation. Hence, users need to configure the port channel groups and member ports correctly on
both end devices.
