# Update a logical interconnect Link Aggregation Control Protocol (LACP) timer

The LACP timer controls the frequency of the Link Aggregation Control Protocol Data Units (LACPDU) that are sent between the logical interconnect and the external switch to form a LAG (Link Aggregation Group). This timer can be set to the following:

`Short` | A message is sent every 1 second with a 3 second timeout.
`Long` | A message is sent every 30 seconds with a 90 second timeout.

The long setting allows for situations such as preventing a timeout and loss of communication during an external switch firmware upgrade.

### Prerequisites

- Minimum required session ID privileges: Infrastructure administrator

Updating the Link Aggregation Control Protocol (LACP) in an uplink set using REST APIs
Select a logical interconnect URI. `GET /rest/logical-interconnects` Get the logical interconnect using the URI from step 1. The associated logical interconnect group URI is returned in the response body. `GET /rest/logical-interconnects/`{id}`` Get the logical interconnect group associated with logical interconnect. The associated uplink sets URIs are returned in the response body. `GET /rest/logical-interconnect-groups/`{id}`` Select an uplink set URI and update the LACP timer attribute (`LacpTimer`). `PUT /rest/uplink-sets/`{id}``
