Universal Compute Platform supports the IEEE 802.3ad implementation of Dynamic Link Aggregation Group (LAG), with control managed by the Link Aggregation Control Protocol (LACP). When you join two or more ports into a LAG interface, the network bonds the ports and treats them as a single logical port interface. LAG interfaces increase link throughput and provide redundancy in case of a link failure.
Consider the following when configuring LAG:
Supported port combinations are: ICC1 and ICC2, and any combination of two to four data ports so long as the ports are configured to run at the same speed.
An ICC port and a data port cannot be combined into the same LAG interface.
A single port cannot be added into more than one LAG interface.
The LAG interface inherits VLAN assignments automatically from newly added port members.
Universal Compute Platform supports LACP-based LAG only. However, engine applications that support LAG, and which run on Universal Compute Platform, must use static LAG only. The LACP configuration from Universal Compute Platform creates and manages the aggregated link, and the static LAG configuration from the engine runs on that link.
When deploying LAG, the LACP expiry timeout on Universal Compute Platform is set to long. For the switch on the other end of the LAG connection, configure the LACP expiry timeout to long.
