Inspect COS
Setting Description Factory Default
Enable/Disable Select the option to enable EDS-P510 to inspect the 802.1p
COS tag in the MAC frame to determine the priority of each
frame.
Enable
NOTE The priority of an ingress frame is determined in order by:
1. Inspect TOS
2. Inspect CoS
3. Port Priority
NOTE The designer can enable these classifications individually or in combination. For instance, if a ‘hot,’ higher
priority port is required for a network design, “Inspect TOS” and “Inspect CoS” can be disabled. This setting
leaves only port default priority active, which results in all ingress frames being assigned the same priority on
that port.

egress queues.
0: Low
