• Phy Buffer Scheduler – phy (air interface) buffer schedule profile (refer to Phy
Buffer Scheduler feature).
4.8 Phy-Buffer-Scheduler
Two profiles of air interface scheduler are available, introduced in SW release 2.3.0:
• Default profile – the profile that systems running SW release 2.2.1 or higher
the only profile available with SW versions prior to MH R2.3.0
• Profile-2 – the profile that was used by systems with SW 2.2.0 or earlier.
These profiles optimize the air interface scheduler to optimize the performance of
different network topologies or traffic scenarios. Choosing the most relevant profile
should be performed after consulting Siklu support, to account for the network
topology, traffic scenario and other requirements of your applications.
By upgrading the SW to 2.3.0, the profile that will be used in default.
The CLI syntax for the command is as follows:
set system phy-buffer-scheduler <default|profile-2>
4.9 DHCP Option 82
DHCP Option 82 is a common method for edge devices to provide identity information
to the core equipment in broadband access networks. It eliminates the need for the
service provider to configure the Residential Gateway (RG), which can be provided by
the user. The BRAS / Broadband Gateway in the network will use the information
provided with Option 82 to open the committed service(s) to the end user. The first
serving network device, viewed from the user side, a MultiHaul™ TU in this case, adds
the subscriber identification to the DHCP requests sent into the broadband access
network by the RG. MultiHaul™ supports the following sub-options of DHCP option 82:
Agent circuit ID: identifies the ingress port of the DHCP request, can be used to pass
combinations of the TU name, its number in the sector, the physical port number on the
TU or the VLAN ID assigned to this subscriber.
Agent remote ID: used to identify the user device/RG itself by mean of its MAC address
(MAC address must be entered), or to identify the user by its account name or by the
service id.
Subscriber ID: another option to identify the subscriber, by their name or some other
fixed identifier, independent of the serving network.
One or more sub-options may be configured on any of the physical ports of the BU or
TU, to identify the subscriber and its services. When a MultiHaul™ unit receives a DHCP
request on a physical port where Option 82 handling is configured, it will add the sub-
option fields and will forward the request to the DHCP server in the network. When the
DHCP reply is received from the server, the option 82 identifier(s) are removed before
