Hello,

1) 

Right now when using proxy-arp under smart VLAN feature by configuring VLAN Interface (vlanif) in OLT, an IP address has to be specified. However, this IP is not actually active at all. Would it be possible to do vlan proxy-arp without an IP address?

2)

Currently with smart VLAN, the proxy-arp with vlanif, OLT will reply to the ARP request with its own MAC address. It would be very helpful if there could be a setting which could alter which MAC address the OLT should reply to.

Any comment on this? Or any work-around?

Tku,

Hi ram.narula, I ll try to reply your question.

1) in general, ARP proxy is often used for interconnection between sub VLANs in a super VLAN, that means, set the vlan attribute to "super", but ont to smart.

As to the IP address, I dont think it is a necessary factor. It depands on your service type.

lets  change a word to say, for the Layer-2 application, the packets are forwarded based on VLAN+ MAC (in general) , so you need not to set the IP address for the VLAN interface; While for the layer-3 application, IP is necessary .

Here s an example for ARP-proxy:

http://support.huawei.com/hdx/hdx.do?lib=SE000070936731187392&v=02&tocLib=SE000070936731187392&tocV=02&id=cfg_cli_0142&tocURL=resources%252fcfg%255fcli%252fcfg%255fcli%255f0142%252ehtml&p=t&fe=1&ui=3

 

2)

This picture is used to describe the principle of ARP -proxy.

We can see that the Super VLAN functions as the proxy, 

When it receives the ARP request packets from PC1, it sends the MAC address of its virtual Layer 3 interface to PC1, and searches its ARP mapping list for the MAC address of PC 2.

• If the ARP mapping list contains the MAC address of PC 2, the packets from PC 1 can be forwarded to PC 2 through the virtual Layer 3 interface.
• If not, it broadcasts the ARP request packets through the VLANIF interface to request the MAC address of PC 2.

So all packets will be proxyed by the VLANIF interface in the ARP-proxy, and the PC1 can never know the MAC addess of PC2. PC2 is transparent from the view of PC1.

Hello Kevin,

I've following version of OLT:

There are some issues while deploying this model i.e. I'm not being able to disable isolate mode in this device. Is there any method to disable isolate mode or how can I configure two Intranet clients in a same OLT?


This is my current configuration:

dba-profile add profile-id 7 profile-name "Intranet1" type1 fix 8192

ont-srvprofile gpon profile-id 7 profile-name "Intranet1"
ont-port pots adaptive eth adaptive

ont-lineprofile gpon profile-id 7 profile-name "Intranet1"
tcont 7 dba-profile-id 7
gem add 17 eth tcont 7
gem mapping 17 0 vlan 1910

1910 smart common 2 123 -

Your any positive suggestion will be highly appreciated!

Thanks!
