We have 2 S4048s that are not responding to SNMP queries. They are running version 9.11(2.1) We have created an ACL that allows only specific hosts to query the switches and then during the SNMP configuration we pointed to that ACL. We are not sure if it's a software bug or what. We are going to try and reboot the switch to see if that restores any functionality. Any ideas would be greatly appreciated.
What queries are you trying to use? Are there any errors in the logs? If you disable the ACL does it work?
It works if we remove the ACL and just put in the community string and access type, but that opens up SNMP which is a huge issue. The ACL is correct and I have tried a standard and extended ACL and they both fail.
