IP route issue with K 12.02?
We have a static route for 192.168.1.0/24 to go to 10.1.0.16, which happens to be a point-to-point T1 router. Ever since the upgrade we are having intermittent issues in being able to talk to 192.168.1.x. It will work fine for a while and suddenly stop working. A little while later it will come back online. We've done our due-diligence in troubleshooting the router and T1, everything appears to be Ok there.
Now for the really weird part. When the connection to 192.168.1.x dies, I then go on the router and ping something in that range and it is immediately back up! Is there some new feature of K 12.02 that could be causing this? Like I said, no config changes have been made. :(

Re: IP route issue with K 12.02?
If you have any doubts to the new firmware version, try to boot to the secondary flash image (if you have K.11.33 saved on it) and check it.
If every thing if fine, then you can open a case with HP.
It sounds to me a Dial on Demand Routing that you have on the router, so when you initiate a ping you may not few replies until the route is ready.
Good Luck !!!

Re: IP route issue with K 12.02?
I did end up opening a case last night. I also set up a monitor session with Wireshark, we'll see if that turns up anything else...
Thanks!
Jim

Was there a defined resolution identified for Jim's problem/question?

Re: IP route issue with K 12.02?
Hopefully I will get back to it this week - but I'd be curious if you have any luck clearing the arp table. Also try rebooting the switch to see if the fix "sticks".

Re: IP route issue with K 12.02?
The 5406zl router is in ouer backbone. I have build some vlans and routing is enable on the switch. In one vlan i have client pc and the interface of the provider router. When a client make a connection to the Internet, the first hop is the 5406 Switch. The 5406 have a default route to the internet over the interface of the provider router.
The configuration works very fine, but after some hours, no connect are possible over the 5406 to the provider.
A workaround is a telnet session to the 5406 an from the Switch a ping to the provider net. After this, the connection to the provider net works.
By the way, the connection fails the hole night. so it is not possible to transfer mails from the provider network to the local mail server. BAD Thing
A new Firmware (K12.07) doesn├В┬┤t fix the problem. So, the only way is to make a ticket by HP and hope of an new firmware.
Had somebody an older firmware that will be work ?

Re: IP route issue with K 12.02?
I have worked with a lot of L3 devices. The bottom line is that I'd never trust a HP switch to do the routing for me. There are not enough debugging features, and too many spooky failures.
If there was a way to debug the traffic properly (not talking about 3rd party sniffers), you might find the cause of the problem.
Of course - this is my personal opinion :-)

Re: IP route issue with K 12.02?
Since you can see the issue quite easily and can also fix the issue quite easily by pinging the provider network - you're in the perfect position to get the information HP needs to resolve this.
When the problem occurs capture the 'show tech all' via tftp.
After you have corrected it by pinging the provider, capture another 'show tech all'.
HP should be able to compare the two files (I use ExamDiff to highlight the differences in the files) and hopefully be able to see the difference between the working and not working situations.
