aggregated in a port trunk).
Default Pri Synopsis: 0 to 7
Default: 0
This parameter allows to prioritize frames received on this port that are not prioritized
based on the frames contents (e.g. priority field in the VLAN tag, DiffServ field in the IP
header, prioritized MAC address).
Inspect TOS Synopsis: { No, Yes }
Default: No
This parameters enables or disables parsing of the Type-Of-Service (TOS) field in the
IP header of the received frames to determine what Class of Service they should be
