10.4.7 Management prioritization
In order for you to constantly have access to the device management, although there is a high
network load, the device lets you prioritize management packets.
When prioritizing management packets, the device sends the management packets with priority
information.

On Layer 2, the device modifies the VLAN priority in the VLAN tag.
The prerequisite for this function is that the corresponding ports are set to allow sending packets
with a VLAN tag.

On Layer 3, the device modifies the IP-DSCP value.
