Hello friends,

I have this completely factory restored OLT, it has no configurations whatsoever.


  VERSION : MA5800V100R017C00
  PATCH   : SPH205
  PRODUCT : MA5800-X15


I have a remote PC configured with the IP address 10.x.x.5/24. The PC is directly connected through a network cable, no element in between, I am able to login via SSH. 

The OLT is pingable from the PC side:


MA5800

Figure 1: Ping OLT from PC

But when I try to do the same from the OLT side, it times out.

Command:
          ping 10.x.x.5
  PING 10.x.x.5: 56  data bytes, press CTRL_C to break
    Request time out
    Request time out
    Request time out
    Request time out
    Request time out
  --- 10.x.x.5 ping statistics ---
    5 packet(s) transmitted
    0 packet(s) received
    100.00% packet loss


The meth0 interface information is below:


MA5800-X15(config-if-meth0)#display interface
{ <cr>|ifType<E><null,meth>||<K> }:
  Command:
          display interface
MEth0 current state : UP (ifindex: 6291456)
Line protocol current state : UP
Description : HUAWEI, SmartAX Series, MEth0 Interface
The Maximum Transmit Unit is 1500 bytes
Internet Address is 10.x.x.2/24
IP Sending Frames' Format is PKTFMT_ETHNT_2, Hardware address is 04b0-xxxx-xxxx
Auto-duplex (Full), Auto-speed (1000M)
    5 minutes input rate 30 bytes/sec, 0 packets/sec
    5 minutes output rate 26 bytes/sec, 0 packets/sec
    931 packets input, 99993 bytes
    1069 packets output, 101099 bytes
NULL0 current state : UP (ifindex: 4194304)
Line protocol current state : UP (spoofing)
Description : HUAWEI, SmartAX Series, NULL0 Interface
The Maximum Transmit Unit is 1500 bytes
Internet protocol processing : disabled


The firewall is disabled on both ends.


Any clue of what might be causing this? 


The OLT configuration is attached.


Thanks!

I found the solution.

Actually, disabling the firewall in Windows like this is not enough for successful interconnection.


firewall disabled

Figure 1: Firewall Disabled

Firewall must be disabled for the private network as well:


firewall cfg

Figure 2: Public and Private Network Firewall

After that, the ping is successful!
