Tighten the 4 screws in order crossed, first on onediagonal and after on the other. Use oil ant-seizingMOLIKOTE P-40 between the threads of nuts and boltsbecause often lack of lubrication could cause metal partsseized together.

- Interface: defines the local mngt interface that allows to reach the next hop

- Protocol: specifies how the routing row has been inserted.

8 Queues Management

in input from LAN ports, and the output queues of Radio ports.

The rows of the table correspond to the output queue of the Radio ports:

• Queue 7. Output queue with 7 priority (high priority).

• Queue 6. Output queue with 6 priority.

• …….

• Queue 1. Output queue with 1 priority.

• Queue 0. Output queue with 0 priority (low priority).

The columns of the table (0 ÷ 7) correspond to the Tag 802.1p value.

The active option indicates which output queue (Queue…) the packet in input is associated to, whose value of

priority Tag (802.1p) corresponds to the value 0, 1, 2, 3, 4, 5, 6 or 7.

The MPLS to 802.1p Rewrite table, points out the correspondence between MPLS priority and 802.1p priority

of packets in input from LAN ports and in output from Radio ports.

The active option points out which 802.1p priority every single native MPLS priority is re-mapped to.

Correspondence can be 1 to 1, that is same priority in two fields, or arbitrary according to the function chosen

by the user. For instance, the priority MPLS 7 can be re-mapped as priority 0 in field 802.1p. 49

- Strict 3: all queue 3 packets can go out, after them all the other using 8421WRR policy

WFQ – Strict PriorityLan to Radio queue configuration (WFQ – Strict Priority)

Actual WFQ is the value

calculated by the

theoretical WFQ weight

Strict Priority: the queue with highest priority is completely emptied (sending of all

the packets) before sending a frame of the queue with lower priority.

WFQ (Weighted Fair Queue): starting from the queues with highest priority up to

the queues with lowest priority, they are empties with a criteria that is based on

the weight defined by the user (minimum 1, maximum 100). This criteria is based on

byte, not frames as WRR.53

Queue Drop TypeLan to Radio Queue drop type (Tail, RED, Queue, WRED)

Drop Type: criterion by which packets are discarded within a queue that is filled:

• Tail. When the queue is full is only deleted the last packet.

• Queue. When the queue is full all of its contents will be deleted.

• Red. Random Early Detection (Random dropping following RED Curve).

• WRed. Weighted Random Early Detection.

54

AGS-H + ALFOPLUS80

Queue Drop Type

The concept of a packet of color (as shown in the technical

specification MEF Bandwidth Profiles for Ethernet Services) is specification MEF Bandwidth Profiles for Ethernet Services) is

used to identify the level of conformity of a packet as regards

as the bandwidth profile associated to the service. Colors:

• Green. The frame is subject to both CIR and CBS

parameters of the profile associated to the service bandwidth

(CIR Frame-conformant).

• Yellow. The frame does not conform to the parameters CIR

and CBS, but complies with the EIR and EIS parameters of the

band associated to the service profile (Frame EIR-

conformant).

The combination of green and yellow applied to incoming

traffic from the LAN ports with "Policing Input Filter" on, is

made as follows:

• All traffic marked CIR / CBS is considered green.

• All traffic marked EIR / EBS is considered yellow. 55

• Output C Vid. New value of C-VID you wish to forward to Radio port.

• Input C Vid : Input packets with old C-Vid to overwrite.

• Output C Vid : Output packet with new C-VID

• Output S Vid : Output packet with added the new S-VID.

If the Selective Provider Tag is set Enable C_Vid + Priority, in the table Lan to Radio C_Vid Rewrite & Selective

QinQ is possible to add a selective S- VID based on the C- VID and priority.

• Input C Vid : Input packets with old C-Vid to overwrite.

• Input Priority : the criteria of rewriting will be based on priority.

• Output S Vid : Output packet with added the new S-VID.

Ethernet Link Protection configurationThe Ethernet Line Protection (ELP) is a function which allows implementing a protection at physical level (Level 2) between two or more LAN external ports.

The switch operates in automatic mode: the equipment executes the switch when the LOS alarm is present on the LAN port in service. When the alarm clears, the controller does not execute the switch again. The Ethernet line protection is implemented by means of proprietary protocol. As consequence, the ELP switch is managed without considering alarms or settings executed on the other side of the LAN connection.LAN connection.

The parameters that determine the order of switching LAN ports are the same used in the window that controls the STP (Spanning Tree protocol):1.Cost. (Lowest cost = High priority )2.Priority. (Lowest value = High priority )

Example. Assume that the LAN ports 1, 2 and 3 are activated with ELP and cost equal 200000. The LAN port 1 has priority 1, the LAN port 2 has priority 2, the LAN port 3 has priority 3. The LAN port 1 is used for transportation, LAN 2 and 3 are on standby. 64

Trunking Line or LAG

Lan1Lan1

Case 1Lan1Lan1

Case 2

"Ethernet Trunking" allows the aggregation of two or more physical ports (LAN) the same equipment to incorporate into a single logical channel and therefore increase the capacity to transfer ethernet.

“Trunking Line” is done by assigning the LAN interface to a group (Enable-Trunk1, Trunk2 Enable, Enable-Trunk3, Enable Trunk4) and ensure the same configuration of the remote LAN capability (full duplex, same speed).

65

Ethernet Trunking agrees with IEEE 802.3ad LAG (Link Aggregation Group) and the relevant protocol LACP (Link Aggregation Control Protocol).

Who can generate alarms in a radio link system?1 ) Propagations of MicroWave- Interference (in a Link radio turn off the Ptx module (local & remote) and

monitoring the Prx during the day, active Local Link ID)- Desalign of Antenna (check positions and screws, maximize the Voltage AUX

connector present in ODU)- Obstacles in the First Fresnel Zone (tree, tower building, etc …)- Particular condition (heavy rain, stratification of different air temperature, flat

surface)- Using the “Performance Monitoring” Prx, Ptx, BER measuring- Using the “Performance Monitoring” Prx, Ptx, BER measuring

2 ) Radio Hardware faulty- Alarms due of a wrong configurations or actual status of the Radio - Faulty (using embedded RADIO BER TEST to check a Hardware failure)

3 ) External Event- No constant 48 Volt Power supply during the day/night- Very High temperature, humidity inside waveguide.- IDU survival temperature range -10°C to +55° C- ODU survival temperature range -40°C to +60°C- IDU operating humidity 95% at +35°C- ODU Waterproof according to IP65 environmental class 88

MaintenanceMaintenance Consists of two stages:

1) Periodical checks = detect correct radio performance without the presence of no alarm.

Every 3 months or 6 months or 1 year for each equipment, perform the following operations :

- Save Backup of equipment

- Save Inventory Report (Power Tx and Power Rx)

89

- Save Inventory Report (Power Tx and Power Rx)

- Save Signal to Noise value

- Evaluate site condition (dust, opened windows, ventilation,etc.. )

2) Corrective maintenace = takes place as soon as one or more alarms conditions are present.

TroubleshootingTroubleshooting is performed with :

- Check value Power of Transmitter and Receiver.

- Reading Current Alarms and Alarm History labels and trying to figure out which part of the equipment is affected, in the following pages there is a description of alarms.

- Disable All Manual Operations.

- Verifying with RADIO BER TEST a Hardware failure or S/N - Verifying with RADIO BER TEST a Hardware failure or S/N Measure.

- Verifying the correct initialization of the Local and Remote Radio.

- Hot / Cold Restart (minimum 5 minutes turn off)

- Factory default

- Firmware Update

- Replace with a spare part. 90
