Configuring the
traffic load
Before transmitting layer 2 traffic over a MiM trunk, you can
specify the type of traffic load the unit will transmit (Constant,
Burst, Ramp or Flood). The settings vary depending on the
type of load.
For an overview of the available traffic loads, see “Configuring
the traffic load” on page 56 .
Specifying OAM
settings
You can position the instrument at various endpoints in a
Maintenance Domain (MD) or Maintenance Association (MA)
area to verify that no OAM trunk problems occur. You can also
use the instrument to verify point-to-point link layer perfor-
mance per ITU-T Rec. 802.3ah. For details, refer to
“OAM
service and link layer testing” on page 94 .
Filtering MiM traffic Before transmitting or monitoring layer 2 traffic on a MiM
trunk, you can specify settings that indicate the expected
received payload and determine which backbone frames will
pass through the receive filter and be counted in the test result
categories for filtered layer 2 traffic. The settings may also
impact other results.
If you want to observe results for the Customer Link (counts
or statistics), ensure that the B-TAG and I-TAG filter settings,
and the Customer filter settings match those carried in the
analyzed traffic.
To filter MiM traffic
1 If you haven’t already done so, launch the Mac-in-Mac
application for the circuit you are testing (see “Launching
an application” on page 28 ), and then proceed to step 2 .
2 Initialize the link (see “Initializing the link for Ethernet
testing” on page 47 ).
