Transparent, Untagged Frame priority is determined by the
default priority of the port. The
optional values are 0–7.
In order to assign highest priority to
the TDM traffic, it is necessary to
configure default priority of the
appropriate port to 6 or 7. For all
the other ports, default priority can
be configured to any value in the
range of 0–5, depending on the rate
limiting setting.
Frame priority is determined by the
default priority of the port. The
optional values are 0–7.
In order to assign highest priority to
the TDM traffic, it is necessary to
configure default priority of the
appropriate port to 6 or 7. For all
the other ports, default priority can
be configured to any value in the
range of 0–5.
Tagged Frame priority is determined by the
default priority of the port. The
optional values are 0–7.
In order to assign highest priority to
the TDM traffic, it is necessary to
configure default priority of the
appropriate port to 6 or 7. For all
the other ports, default priority can
be configured to any value in the
range of 0–5, depending on the rate
limiting setting.
Frame priority is determined by the
tag priority of the frame. In order to
assign highest priority to the TDM
traffic, it is necessary to configure
tag priority of the TDM frame to 6
or 7. For all the other frames, tag
priority can be configured to any
value in the range of 0–5. If an
untagged frame is received, its
priority is determined by the default
priority of the port.
Double Tagged Frame priority is determined by the
default priority of the port. If the
TDM traffic is tagged, in order to
assign highest priority to it, it is
necessary to set the frame tag
priority to 6 or 7.
For the frames coming from the
user ports towards the network
port, priority is determined by the
default priority of the port.
For frames coming from the
network port towards the user
ports, priority is determined by the
tag priority of the frame.
If TDM traffic is tagged, in order to
assign highest priority to it, it is
necessary to set the frame tag
priority to 6 or 7.
