Network problem   
Dear all

We have QNX 6.4.1 running on a customized board based on PPC440ep processor, using customized version of AMCC PPC440 EP/
GR BSP. Board has two ethernet interfaces on different subnet .

Rarely we have problem with ethernet. Board not detected by pinging it through PC (ping fails), but PC can detected 
through board using ping command.

Both PC and board are connected to one switch.

Is there any idea about this problem?

Thanks
Hugh Brown

Re: Network problem   
What is the output of nicinfo when this happens? Are there any error
messages in sloginfo? We will also need the output from "ifconfig".

Re: Network problem   
Dear Hugh

Thanks for your response. 
Because problem occurs rarely, I put the board under test, as soon as it fails, I'll report the sloginfo messages. 
following is ifconfig output. 
 
# ifconfig
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 33192
        inet 127.0.0.1 netmask 0xff000000
en0: flags=80008943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST,SHIM> mtu 1500
        address: 00:65:43:21:22:60
        media: Ethernet 100baseTX full-duplex
        status: active
        inet 192.168.100.226 netmask 0xffffff00 broadcast 192.168.100.255

        media: Ethernet none full-duplex
