4. Native Ethernet
The Ethernet traffic is sent over a single hop or
through a network. Native Ethernet traffic is sent
over a dedicated physical link instead of being
transported over PDH or SDH. Native Ethernet
enables more efficient use of bandwidth and
maximizes Ethernet throughput since no PDH
overhead is added.

5. Shows an overview of the Ethernet services.

6. Ethernet over Packet Links via a WAN with an RL-IME Group

7. Right click on the Modem Unit used for the Native Ethernet→ Confugue→ Configure
Radio Link

8. Configure the Capacity of the link ,in this example we have configured the link for 345
Mbit/s

9. We can also select the no of E1 for the TDM traffic which will reduce the capacity of
Ethernet Traffic

10. Now configure the LAN port from we are taking Ethernet Traffic

11. Assign a Switch Port to the LAN port ,here we have assigned Switch port 1

12. Now configure RL-IME link for Ethernet Traffic, here we will configure RL-IME 1/7/100

13. Right click oon RL-IME 1/7/100 →Configure

14. Assign the Packet link to RL-IME group, here we have assign Modem unit no 2 (MMU2H)
Select link then press
button

15. Now packet link is assigned for RL-IME 1/7/100

16. A WAN port with name “WAN 1/7/100” will be automatically corresponding to RL-IME
1/7/100 now we have to configure this WAN port

17. Assign Switch port to the WAN 1/7/100,here we have given port no 2

18. We can see the configuration of any Switch port, we can see here that Switch port no 1 is
assigned to LAN 1/7/3,we need to take care that LAN port should be configured as UNI

19. Switch port 2 is assigned to WAN port & It should be configured as NNI

20. No we need to configure the VLAN for layer 2 switching,

21. We have Default VLAN with VLAN ID 1,this should be always there and all ports should
be defined in Default VLAN,

22. After creating VLAN we can see that the LAN port is UP & Receiving & Transmitting the
Ethernet Frames

23. We can also see that the Radio link is carrying Ethernet traffic now

24. Another Radio link we have configured with less Ethernet traffic

25. Check the WAN port status now

26. We have now observed both WAN port are UP & having traffic

79. Adaptive
Modulation

80. Hitless Adaptive Modulation is supported by MMU2 H and enables automatic
switching between different modulations, depending on radio channel
conditions. Hitless Adaptive Modulation makes it possible to increase the
available capacity over the same frequency channel during periods of normal
propagation conditions.

81. Configure the Minimum & Maximum Capacity of the link for the QOS

82. We can see that in good condition link capacity is 154 Mbps with 128 QAM

83. When radio conditions goes bad then link capacity reduces to 90 Mbps with 16 QAM to make sure that the
impotant date still running on the microwave link.

84. Frame
Addmission

85. Frame admittance - It is possible to block or admit the following frame types at
the network edge:
Q-Tagged (priority bits/VID set in Q-tag)
Priority tagged (only priority bits set in Q-tag)
Untagged (no Q-tag)
Other/unrecognized frame types (for example S-tags) are discarded at the
network edge.

86. We can defined the type of frames we want to access ,default is Admit All

87. We have 2 options:-
1. Admit Only VLAN-tagged Frames
2. Admit Only Untagged And Priority-tagges frames

88. Link Aggregation group
LAG

89. Link Aggregation Group (LAG),
which aggregates several external
Ethernet links into one logical link
and provides line protection.

90. Right Clink on Ethernet-Switch →Configure→LAG

91. Click Add Row button

92. Define Master port & Member ports for LAG

93. Save the configuration by clicking Save button

94. MAC Address
limiting per
port

95. MAC address limiting per port. It is possible to limit the MAC address table per port
to prevent external devices/networks to flood the customer network with MAC
addresses.
It will allow operator to set the limit of the MAC address in Network as per the
requirment.

96. Click on Switch port & define Maximum Learned MAC address, In out example Switch port will
listen only 20 MAC address & drop all other data.

97. Default value is 0 which means it will learn all MAC addresses. Maximum Value is 0 to 16383

98. MAC WHITE
LIST
A source MAC address based white list can provide port access control at the
network edge

99. Right Click on Ethernet Switch → Conofigure → MAC white list

100. Click on Add Row

101. Configure White list Name & click Save

102. Give MAC address and again click Save

103. Now configure the Switch port, now in example now Switch port 1 will only listen data from MAC
addess 00:00:00:00:00:01

104. Now Switch port is configured for MAC White list “test”

105. If we wish to delete MAC white list then we have to make sure it is not assiegned to any Switch port
else we will face Error messege

106. It gives the facility to measure the traffic on any port to be mirrored on another port for
quality measurement, Wire shark is best tool to get the output on local machine for
investigation
Port Mirroring

107. Right Clickn on Ethernet Switch →Tools →Port Mirror

108. Click on Add Row

109. Now here we have mirroed port no 2 to port no 5, Port no 5 is connecte to external machine like
laptop not using Wire shark we can monitor all data going Via port no 2

110. RSTP activates a redundant link in case of link failure and protects the
network from infinite loops
Rapid
Spanning Tree
protocol

111. Right Click on Ethernet Switch → Configure → Spanning Tree

112. Configure STP as RSTP & save the configuration.

113. Select all WAN ports to aviod looping,we have no need to select LAN ports

114. Static Unicast Filtering

115. Right Click on Ethernet Switch → Configure → Static Unicast Filtering

116. Select VLAN no (here we have taken VLAN-222)

117. Click on Add Row, Select required Switch port

121. Right click on Layer 1 Connection & go to Configure

122. Define the WAN & LAN port you want to configure for the Layer 1 Configuraion & save it

123. Weighted Fair Queuing
(WFQ).

124. A potential problem with strict priority scheduling
is that queues with lower priorities may be
starved, that is, the frames in the queues are not
handled and eventually dropped. By using
Weighted Fair Queuing (WFQ) it is possible to
avoid starvation. When WFQ is used, queues
can be configured with a weight parameter,
which decides how large share of the available
output port bandwidth that is dedicated to the
specific queue,

125. • Example to understand WFQ

126. Right Click on Ethernet Switch → Configure → General

127. Click on “Configure QoS”

128. Select the Scheduling profile as per design

129. Click yes

130. Now WFQ is configured
Clink on Configure Queues
,check next slide

131. Queue is configured now
Click on Configure Queue Size & check
next Slide

132. Here we can define Queue size as per Traffic class to maintain QOS

133. Now check another option & see the “Configure Queue”

134. We can see that the Scheduling is now different as per Network priority

135. Now we selected another Scheduling profile

136. We can see that the Scheduling is now different as per Network priority

137. Layer 1 & layer 2 Connection
Wizard

138. Select Wizards → Go to Layer 1 Connection Wizard

139. Click on Next (option will be I down right side of window)
