The priority-of-link-quality protocol command sets a protocol type for link quality detection packets.
The undo priority-of-link-quality protocol command restores the default setting.
priority-of-link-quality protocol { icmp | tcp-simple }
undo priority-of-link-quality protocol
| Parameter | Description | Value |
|---|---|---|
| icmp | Sends ICMP probe packets. | - |
| tcp-simple | Indicates that TCP packets are used to check network connectivity. A link is considered available upon the reply to the first detection packet by the destination device, not completion of the three-way handshake. | - |
The default protocol type of link quality detection packets is tcp-simple.
After you use the mode priority-of-link-quality command to set the intelligent uplink selection mode to load balancing by link quality, you can use the priority-of-link-quality protocol command to set a protocol type for link quality detection packets.
Set the protocol type to icmp for link quality detection packets in global intelligent uplink selection.
