HST-3000 Ethernet Testing User’s Guide
– Basic layer 4 support. If you purchased the TCP/UDP
option, you can transmit and analyze IPv4 traffic with TCP
or UDP headers in terminate mode. The IPv6 Traffic
option is also required if you want the ability to transmit
and analyze layer 4 IPv6 traffic.
– MPLS support. If you purchased the MPLS Traffic option,
you can transmit MPLS encapsulated traffic when testing
and qualifying core and metro networks.
What’s new
This release of the Ethernet SIM supports the following new
features:
– Loop Types. When you configure an instrument for a loop-
back test, you can specify that you want to issue a
Unicast loop-up command, or a Broadcast loop-up
command. Unicast commands are used to loop up a
specific test instrument on the far end; Broadcast
commands are used to loop up the first instrument on the
network that responds.
– Mac-in-Mac testing.If you purchase the MiM testing
option, you can transmit and analyze MAC-in-MAC
Ethernet traffic over a PBB (Provider Backbone Bridged)
network to verify end-to-end connectivity, and analyze link
performance. For details, see
“MAC-in-MAC testing” on
page 105 .
– Link and service layer OAM testing. OAM messages are
supported, enabling you to identify trunk problems so you
can initiate a switch to a protection path. When testing
Ethernet First Mile OAM communications, you can loop-
back an adjacent node or Ethernet demarcation device
(EDD), and then exchange messages with the node or
device to verify that auto-discovery and error notification
are functioning properly. For details, see
“OAM service
and link layer testing” on page 94 .
– Layer 2 transparency testing.You can transmit and
analyze layer 2 traffic with headers (such as CDP, VTP,
STP, and R/STP) to verify that a circuit can support a
variety of control protocols irrespective of the transport
