I upgraded a Summit X460-48p from version 22.214.171.124 to 126.96.36.199.
After the upgrade, our monitoring servers (cacti, zabbix) are not able to get SNMP information from the switch anymore (SNMP v2c, readonly community).
In the switch logs, i see a lot of error messages "
Except the upgrade, nothing has changed in the configuration of the switch and the monitoring servers.
I have compared the configuration of the upgraded switch with another switch (not upgraded yet), i see some minor differences, but nothing obvious that could explain the SNMP failures.
I also checked this post (https://community.extremenetworks.com/extreme/topics/snmp-read-problems-bad-community-name-since-xos...) but it seems i don't have the same problem, as my configuration still has the "configure snmpv3 add user" commands
Maybe someone in the community has already experienced this issue.
Thanks for your help.
