6. Configure Stack configuration to Off to disable MPLS generation over the current
flow. Set Single MPLS label or Double MPLS label to generate IP packets carrying
one or two MPLS labels.
7. If you have configured Single MPLS label in the previous step, type the correct
values for Bottom label, Bottom traffic class and Bottom TTL. If you have config-
ured Double MPLS label, enter the values for Bottom label, Bottom traffic class,
Bottom TTL, Top label, Top traffic class and Top T TL.
4.4.3. Configuring the Port Local Network Profile
The test equipment requires a local IP profile when it is operating in IP Endpoint mode.
Even if the traffic generator has been configured to work with a custom IP address
(different to the local IP address), the equipment still requires an internal address for
some tests like the IP Ping or the Traceroute. Furthermore, some control and signalling
protocols may work with the information stored in the local IP profile only. Specifically,
it must be noticed that the test unit only responds to ARP and ICMP echo requests from
the IP address and VID configured in the local profile. This fact must be taken into
account when the source IP address is configured to something different to Local
(Network layer settings) and Encapsulation is set to something different to Local profile
(Frame layer settings).
Configuration of the local IP profile is available form the port specific settings within the
Setup menu (See section 2.3).
Top traffic class This field contains the traffic class identifier for the top MPLS
header. It was first thought that this field could carry the 3
Type-of-Service (ToS) bits defined for Class of Service (CoS)
definition in the IP version 4, but currently, the ToS field is
being replaced by 6-bit Differentiated Services Code Points
(DSCP). This means that only a partial mapping of all the
possible DSCPs into this field is possible.
This field is enabled only if the user has selected Double
MPLS label in Stack configuration.
Top TTL This field contains a Time To Live value for the top MPLS
header. The value of this field is decremented by one unit
every time the packet traverses an LSR. The packet is dis-
carded if the value reaches 0.
This field is enabled only if the user has selected Double
MPLS label in Stack configuration.
