What is the System Architecture of Huawei GPON OLT?

Huawei MA5608T/MA5603T/MA5800T uses the system architecture containing three modules: M1, M2, and M3.

• The M1 service port module provides various service access ports, such as PON, P2P, POTS, and xDSL service ports.
• The M2 core processing module implements CPU processing, Ethernet switching, and service processing.
• The M3 uplink port module transmits service flows upstream to network-side devices.

Figure 1 System architecture

In the preceding figure:

• The M1 service port module and M3 uplink port module connect to different boards. For details of working principles of each module, see board description in the Hardware Description.
• For details of service flow directions in the M1 service port module, see board working principles in the Hardware Description.
• The service flows processed by the M2 core processing module are classified into two types: One type of service flows are transmitted upstream after they are processed by the Ethernet switching module and the M3 uplink port module; the other type of service flows are transmitted upstream after they are processed by the Ethernet switching module, service processing module, and then Ethernet switching module again.

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.

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
