How to realize flow qos mode configuration on Huawei MA5680T GPON?

For realize scheme with two flows Huawei MA5680T GPON i create new gpon-line profile with these settings:

ont-lineprofile gpon profile-id 10 profile-name "Flow-Test"
qos-mode flow-car
mapping-mode vlan-priority
tcont 1 dba-profile-id 10
gem add 1 eth tcont 1
gem mapping 1 0 vlan 1001 priority 0
gem mapping 1 1 vlan 1001 priority 5
commit

It means, that we use 1 gemport, but mapping it with different mapping index for priority 0 and 5.

After that we create service port for this gemport and Huawei ONT with unlimited traffic-table index 6 with priority policy Tag-In-Package:

service-port 1 vlan 1001 gpon 0/5/0 ont 1 gemport 1 multi-service user-vlan 1001 tag-transform translate inbound traffic-table index 6 outbound traffic-table index 6

That's all, during test we can see, that flow with priority 5 has superior between flow with 0 priority.

Does Huawei GPON ONT HG8245H support 802.11e (QoS)?

Huawei GPON ONT HG8245H support only WMM which is part of the 802.11e.

802.11e defines Quality of Service (QoS) for the wireless LAN, which provides the required service quality for voice and multimedia applications and enhances network performance. Wi-Fi Multimedia (WMM) defines four access categories, including voice, video, best effort, and background to optimize network communication quality and ensure stable access of corresponding applications to network resources. The WMM standard is a subset of IEEE 802.11e.

In conclusion, HG8245H support partially the 802.11e standard.

How to solve DHCP issue on GPON side?

Analysis:

We found Huawei OLT has enable arp unicast function which only allowed 8 dhcp user dial up in one service port. OLT will discard dhcp packets whose amount is more than 8 dhcp users.

ARP unicast function description:

The function of ARP unicast is shown below and it is not needed to enable normally unless there are lots of ARP packets in the network.

If the ARP broadcast converted to unicast function is enabled on the network side, MA5680T/MA5683T/MA5608T queries user's going online information based on destination IP address and VLAN after receiving an
ARP request.

·         After detecting that a user goes online, MA5680T/MA5683T/MA5608T sends the ARP request to this user.

·         If no online users are detected, when security arp-unicast unknown-policy is set to discard, the ARP request is broadcast cascading-side and network-side ports excluding the source port in the VLAN.
However, the user side cannot receive ARP requests sent by the network side; when security arp-unicast unknown-policy is set to forward, the ARP request is broadcast to the user-side, cascading-side, and network-side ports excluding the source port in the VLAN.

Solution:

Disable ARP unicast function.

Optical power management : ALS function

Note that ALS function need to be activated on each port, in this way the laser will not harm anybody!

When a client-side or WDM-side fault occurs during the transmission of non-OTN services, the automatic laser shutdown (ALS) function, if being enabled, shuts down the laser(s) on the associated transmit ports. It turns on the laser(s) on the transmit port(s) again when the fault has been eliminated.
 
The automatic laser shutdown (ALS) function needs to be configured at each required port.
 
ALS application for Huawei OSN 8800

How to collect dump on PON port of MA5600T by tftp?

Please follow belowsteps:

MA5680T(config)#acl 4000

// create the ACL

MA5680T(config-acl-link-4000)#rule 1 permit

MA5680T(config)#diag

MA5680T(diagnose)#su

// enter su mode

MA5680T(su)%ckup-server debug primary 80.73.64.23 tftp

// tftp server ip , for example: 80.73.64.23

MA5680T(su)%ture item 1 inbound link-group 4000 rule 1 port 0/1/3

// direction can be: inbound / outboun / bidirection

// PON port, for example: 0/0/0

MA5680T(su)%ture start -c 1000

// count of collected packets, for example: 1000, in attach such case

// If set count of packets more then need, capturing can be stop by command:

MA5680T(su)%ture stop

What are the Functions and Features of Main Control Card EH1D2SRUC000 on Huawei S9700 Switch?

Main Control Card EH1D2SRUC000 integrates control and switching functions and provides the control plane, management plane, and data plane, which are described as follows:

• The control plane is responsible for protocol processing, service processing, route computing, forwarding control, service scheduling, traffic statistics collection, and system security.
• The management plane is responsible for system status monitoring, environment monitoring, log and alarm processing, system software loading, and system upgrades.
• The data plane provides high-speed, non-blocking data channels to implement service switching between service modules.

The EH1D2SRUC000 consists of the following modules:

• Control module: provides the control and management plane for the EH1D2SRUC000 and the entire system, implementing protocol processing, route computing, forwarding control, system management, and system security.
• Switching module: provides the data plane and high-speed service channels for service switching.
• Local clock module: provides working clock for chips of the control module, switching module, and device management and monitoring module.
• Device management and monitoring module: provides a controller area network bus (CAN Bus) module to monitor the EH1D2SRUC000 and manage the CAN Bus modules of LPUs.
• Power supply module: provides power for the EH1D2SRUC000.
• Apply to Huawei S9706/S9712 Switch

Table 1 describes the functions and features of the EH1D2SRUC000.

Table 1 Functions and features of the EH1D2SRUC000

Function and Feature	Description
Basic functions	The EH1D2SRUC000 is the system control and management unit for the S9712 and S9706. It integrates the main control unit, clock unit, switching unit, and system maintenance unit.
Distributed forwarding	Performs concurrent data forwarding using a distributed data plane.
CF card	512 MB by default, expandable to 1 GB or 2 GB By default, the system configuration data, startup files, system software package, and system logs are saved to the CF card.
CSS	The EH1D2SRUC000 can have EH1D2VS08000 installed to provide the CSS service.
Clock	The EH1D2SRUC000 can have LE0D00CKMA00 installed to provide stratum-3 clock, synchronous Ethernet functions.
Redundancy backup	Supported Main control board is mandatory for switches. Each switch must be configured with one or two main control boards. When one main control board is configured for a switch, the main control board can be installed in either main control board slot of the switch. When two main control boards are configured, the two main control boards work in hot standby mode to improve reliability of the switch. The active and standby main control boards monitor the status of each other. If the active main control board fails, the standby main control board automatically becomes active to ensure uninterrupted services.
Hot swap	The EH1D2SRUC000 is hot swappable. Before removing the active EH1D2SRUC000 card, perform an active/standby switchover.
