Table 3-9. Pseudowire PSN Parameters
Parameter Function Values
ToS Specifies the Layer 3 priority assigned
to the traffic generated by this
pseudowire.
For IP networks, this priority is
indicated by the IP type-of-service
parameter for this pseudowire. The
specified value is inserted in the IP
TOS field of the pseudowire IP
packets.
When supported by an IP network, the
type-of-service parameter is
interpreted, in accordance with
RFC791 or RFC2474, as a set of
qualitative parameters for the
precedence, delay, throughput and
delivery reliability to be provided to
the IP traffic generated by this
pseudowire.
These qualitative parameters may be
used by each network that transfers
the pseudowire IP traffic to select
specific values for the actual service
parameters of the network, to achieve
the desired quality of service
You can also specify a Layer 2 priority
by means of the VLAN Priority field,
provided VLAN Tagging for the router
interface used by this pseudowire is
Enable.
This parameter is relevant only when
PSN Type is UDP/IP
Type in the prescribed number, in the range of 0
to 255.
In accordance with RFC 2474, it is recommended
to use only values which are multiples of 4.
Default: 0
Ingress Tunnel
Tagging
Controls the use of an interworking
MPLS label for the receive (inbound)
direction of the pseudowire.
Configuring an inbound label for each
pseudowire is mandatory. When no
outbound label is configured, the
inbound label is also used as the
outbound label.
This parameter is relevant only when
PSN Type is MPLS/ETH
ENABLE – Inbound tagging is enabled.
DISABLE – Inbound tagging is disabled.
Default: DISABLE
