Multi-link Operation (MLO)

---|---|
Cisco IOS XE 17.15.2 |
To alert users about possible disruptions, pop-up notifications or console informational messages will be displayed whenever there are changes to the radio parameters. These messages appear when the workflow is enabled or disabled, or when a radio reset occurs. The lack of support for link re-configuration in Multi-Link Operation (MLO) may lead to client disruption during radio configuration changes. Disruption will occur for clients connected to an AP with 802.11be enabled radio, especially when 802.11be is enabled across all radio bands. |
Multi-Link Operation (MLO) allows Multi-Link Devices (MLDs) to maintain associations and simultaneously transmit data across multiple frequency bands, including 2.4-GHz, 5-GHz, and 6-GHz band.
MLO is an essential feature of the IEEE 802.11be protocol. MLO is linked to the activation state of the Wi-Fi 7 standard. Enabling the 802.11be protocol on a device simultaneously initiates MLO capabilities, ensuring optimal network performance. Conversely, the deactivation of the 802.11be standard automatically results in the discontinuation of MLO functions.
Multi-link Operation (MLO) Modes
There are three widely adapted MLO modes.
-
Multi-Link Single Radio (MLSR)
-
Enhanced Multi-Link Single Radio (EMLSR)
-
Multi-Link Multi Radio (MLMR)
