I've recently installed a couple Rocketlinx ES8520-XT switches that are giving me some issues. After a couple days i'm getting memory errors and need to power cycle the switch. I'm running the following: Loader version 2.0.1.1 ; firmware version 1.2c-20190514-14:27:41; System OID 1.3.6.1.4.1.2882.2.2.24

I had a screen shot of the memory errors but accidentally forgot to save it. Can probably get it again the next time it happens.

ALso - unable to ping the switch after this happens although I can ping devices attached.

Thoughts?

Hi aloadmin,

I'll ask our Rocketlinx people here and see what they say about this. I'll get back to you asap.

Hi aloadmin,

The screenshot you mentioned would be helpful in this case. I'd need to see the specifics of the memory error before I could analyze where the problem lies.

In the meantime, can you gather the following information? You mentioned that this occurs every couple of days. Is there an exact span of time (like two days)? What is attached to the switch (devices and uplinks). Are the troublesome ES8520-XTs all on the same network segment or are they on different network segments? A diagram of the network would also be helpful.

You can email the info to me at krees[at]us.pepperl-fuchs.com

Thanks,
Kurt

Kurt - i was able to get some info from the RL switch this morning. Drawing is a bit crude and could only get screen snips off switch before i had to power cycle it to get it working again. Hopefully some of this will help.

also - in the Rocketlinx switch (the one that i've uploaded the screen snips for) is the following SFP: Proline E1MG-LX-PRO 1000Base-LX SFP SMF 1310nm 10km., LC

at the other end in the Extreme switch on the other end is the following: Axiom GLC-LH-SM-AX 1310nm 10km. Single mode fiber between the two switches.

The other RL switch that I aslo have a similar problem with (in the drawing) i need to get the SFP info from it yet.

Time wise - i haven't been able to for sure figure that out. Seems to be a couple days but i don't know for sure.

Thanks
Chris

Hi Chris;;

It is still being looked into. I will follow up and see what the latest is.

Hi Chris,

I just heard back from the person looking into this
They will need to contact the developer of the switch firmware to get more info. This will take more time.

One suggestion was to save your configuration, reset to factory default, then reload your configuration to see if that clears the issue.

I swapped out one of the switches altogether (and I've experienced this on 3 different switches now) so i don't think a reload of the config is probably the answer? I'll keep an eye on it and see if i can figure anything out on our end. Please keep me up to date on what they find...

thanks

Hi Kurt - just checking if there was any update on this. I'm still having to reboot these switches every few days otherwise i am unable to ping them (and telnet) to them.

Hi,

Nothing yet. I will follow up on Monday. Christmas break is in effect.

Hi Chris,

I just followed up, we're still waiting to hear back from the developer. I have some questions about the symptoms.

1. If the switch is on a network with less traffic, will it still have issues?
2. Are there any network security software running on the network (NESSUS for example)?
3. Would this be reproducible in a lab environment? If so, how parameters are you using so we can try and reproduce here?

Thanks,
Kurt

Hi Kurt,

1 - it is on a segment of the network with very little traffic already.
2 - no network security software
3 - not sure if reproduceable....i am going to swap one of them out today with one that I did a "Load Default" on. Will see what happens with the new one. Also - will bring the other back to my office and leave on and see what happens when it runs off of the network.

Thanks,
Chris

Hi Chris,

I was informed about a newer firmware for the ES8520-XT this morning. Our testers will be downloading it to test on a switch. However, they have been unable to replicate the issue. I will let you know when the new firmware is available

Thanks Kurt - I'm still having the issue and not able to determine what is different on a good one/bad one so maybe a new firmware will help. Let me know when it is available for use.

Thanks

Hi, I just followed up with the people testing the firmware. So far it is going well and should be available by the end of these week assuming no problems occur.
