Network traffic stops

[Adrien Amaral]

Hi folks,
Have cold installed an E55 on HP-UX 10.01. The NIC is up and running, routing and all TCP services are running fine. If I increase the traffic on Lan0, the system will take some and suddenly will stop all traffic on the card. Loopback Ping works but no incomming or outgoing traffic works.I'm unable to ping the net, nor able to scan any ports on the server. This issues presents mostly during FTP transfers.

TIA

Adrien

This sounds like a patch issue - have you get a decent patch bundle installed on 10.01 ?

Sometimes you can have problems with 100Mb cards being set to autonegotiate on the hub/switch end (which aprticularly causes ftp problems) but your E only has an internal 10Mb card - unless you have an external 100Mb.

Yes I have the Y2K patch installed on the machine but seems no to be enough to solve this issue

Yes a single NIC and the machine is plugged on a switch that I've frozed the autonegotiation to 10Mb

Do you have any patches recommended (minimum list ??)

TIA

Cor, 10.01 is really old. The Y2K patch(es) is not going to be enough, you need an OS patch bundle. You can possibly still download a bundle for it at software.hp.com

Is your switch/hub set to 10HD (not 10FD).

[Adrien Amaral]

The switch is HD. I'll check for the OS bundle.

Thanks

I expect that it is not a patch issue. I have several unpatched 10.01 boxes and they do not have this problem. I think instead you are getting a lot of errors and something, probably the switch, pulls the plug when an error limit is reached. Check to make sure you have the same duplex hard programmed in on both the switch and the box, replace the cable or the NIC.

The loopback ping does not really test anything. It does not go out on the wire but is looped back at a higher level.

I'm with Ron. Verify the speed/duplex setting on the box as well as the switch. If you use cisco switch, then you can read actual speed, duplex setting for each active cable connected to the switch.

Folks,

I've applied patch PHNE_12756 and it solved my issue. The speed was locked on the switch and the situation arrised even on a hub. Thanks for all the input
