1238 buggy interface issues

[Anonymous]

We have a 1238 using NV123XA-17-09-03-00.biz

Today a few hosts started losing connectivity - interfaces started dropping off the MAC table.

We moved the affected hosts to another switchport and the host came online.  Plugged the host back into its original port and lost connectivity.  There is no port-security on the switch.  The weird issue is that when we unplug the host from the affected switchport, the switchport is still showing connected and is still sending out packets/broadcasts.

We rebooted the switch and that cleared the affected switchports and they show notconnected now however we are now experiencing strangeness regarding the MAC table. 

The mac table will show 22 MAC's.  we run the command again and it will only show 6 , we run the command again and it will show 4 and we run it again and it will show 24.  The MAC table is not stable currently. 

I am not sure if we are experiencing some bug or something.

Thanks,

Sean

Thank you for asking this question in the support community.  Based on the description you provided, it sounds like this may have been something that was fixed in newer software.  I would recommend upgrading the firmware to 18.02.05.00.  Here are the release notes for this version:  NetVanta Internetworking Product Release Notes - 18.02.05.  If you have questions about how to upgrade firmware, please review the Upgrading Firmware in AOS document.

I apologize, you are correct.  The latest firmware version for the NetVanta 123x series is 18.01.04.00, and that is the version I would recommend for that product family at this time.

Please, let me know if you have any additional questions.
