Figure 134: CoS Access Priorities Form

Port(s)

Synopsis: Any combination of numbers valid for this parameter

The port number as seen on the front plate silkscreen of the switch (or a list of ports, if

aggregated in a port trunk).

Normal Access Priority

Synopsis: 0 to 7

Default: 0

When frames that were originally received untagged are transmitted from a tagged port the

switch will insert 802.1Q VLAN tags. This parameter specifies the value the switch will insert

into the priority field of the tag, if the frame was assigned Normal priority Class of Service upon

receiving and is getting tagged upon transmission from the specified port. This parameter does

not affect frames that were originally received tagged.

Crit Access Priority

Synopsis: 0 to 7

Default: 4

When frames that were originally received untagged are transmitted from a tagged port the

switch will insert 802.1Q VLAN tags. This parameter specifies the value the switch will insert

into the priority field of the tag, if the frame was assigned Critical priority Class of Service upon

receiving and is getting tagged upon transmission from the specified port. This parameter does

not affect frames that were originally received tagged.
