Traffic Generation
69
Address range size Configures the number of MAC addresses within an address
range.
This control is valid only if Des. MAC address type is set to
Range. In this case, the Ethernet frames transmitted in the
current stream will contain as many destination addresses as
previously configured in this field. The destination MAC
address is increased by one unit for each transmitted frame
starting with the value configured in Destination MAC
address. If there are no more addresses left in the range,
transmission returns to the initial address and starts the pro-
cess from the beginning.
Ethertype Ethertype value carried by the frames generated in the cur-
rent stream. This value is found within the Ethernet Type
header field in DIX / Ethernet II frames or within the LLC /
SNAP header in IEEE 802.3 frames.
Depending on the configuration, the Ethertype value is fixed
and cannot be set by the user. If the operation mode is IP
endpoint, the Ethertype is automatically configured to 0x0800
(Internet Protocol, version 4). If the payload type is config-
ured to SLA in Ethernet endpoint mode, the Ethertype is set
to 0x8902 (IEEE 802.1ag / ITU-T Y.1731 OAM) to account for
the special structure of the Ethernet SLA measurement pay-
load (See section 4.1.3, however).
C-VID VLAN identifier assigned to tagged frames (IEEE 802.1Q) or
C-VLAN identifier for double tagged frames (IEEE 802.1ad,
Q-in-Q). In frames with two VLAN tags, the C-VID usually
accounts for the VLAN structure corresponding to the cus-
tomer network.
Any value within 0 to 4095 is allowed for this field.
C-VLAN
priority
3-bit class of service (CoS) field defined to set frame groups
with different priorities or to provide specific treatments to
special frames within a network or an administrative domain.
This field is carried by the Q-tag of Ethernet frames with a
single tag or by the C-tag of Ethernet frames with two tags.
Any value from 0 to 7 is allowed for this field. Specific actions
to be carried out on frames with different CoS labels depend
on the network and the service provider.
