After reboot I've noticed difference in config between old and new version.<BR /> <BR /> Old XOS<BR /> configure snmpv3 add community XXXX name XXXX user v1v2c_rw <BR /> configure snmpv3 add community YYYY name YYYY user v1v2c_ro <BR /> configure snmpv3 add target-addr v1v2cNotifyTAddr1 param v1v2cNotifyParam1 ipaddress 172.30.0.6 transport-port 162 tag-list defaultNotify <BR /> configure snmpv3 add target-params v1v2cNotifyParam1 user v1v2cNotifyUser1 mp-model snmpv2c sec-model snmpv2c sec-level noauth <BR /> disable snmp access snmpv3<BR /> disable snmpv3 default-group<BR /> disable snmpv3 default-user<BR /> configure snmp access-profile mgmt-acl readwrite<BR /> <BR /> New XOS<BR /> configure snmpv3 delete mib-view defaultUserView subtree 1.0<BR /> configure snmpv3 delete mib-view defaultAdminView subtree 1.0<BR /> configure snmpv3 delete mib-view defaultNotifyView subtree 1.0<BR /> configure snmpv3 delete community public<BR /> configure snmpv3 add community "XXXX" name "XXXX" user "v1v2c_rw" <BR /> configure snmpv3 add community "YYYY " name "YYYY " user "v1v2c_ro" <BR /> configure snmpv3 add target-addr "v1v2cNotifyTAddr1" param "v1v2cNotifyParam1" ipaddress 172.30.0.6 transport-port 162 tag-list "defaultNotify" <BR /> configure snmpv3 add target-params "v1v2cNotifyParam1" user "v1v2cNotifyUser1" mp-model snmpv2c sec-model snmpv2c sec-level noauth <BR /> disable snmp access snmpv3<BR /> disable snmpv3 default-group<BR /> disable snmpv3 default-user<BR /> configure snmp access-profile "mgmt-acl" readwriteAs a result I have a lot of error messages in log and I cannot access to certain OIDs throug SNMP.<BR /> Login failed through SNMPv1/v2c - bad community name (172.30.0.240)What's wrong? I don't get it.<BR /> <BR /> Thu, 20 Aug 2015 12:40:00 GMT https://community.extremenetworks.com/t5/extremeswitching-exos-switch/snmp-accees-after-15-5-4-2-patch1-5-upgrade/m-p/53159#M14871 eyeV 2015-08-20T12:40:00Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/snmp-accees-after-15-5-4-2-patch1-5-upgrade/m-p/53160#M14872 This looks like a issue which has already been identified and under investigation.<BR /> <BR /> Here is an article with the solution <A href="https://gtacknowledge.extremenetworks.com/articles/Solution/SNMP-communication-lost-after-EXOS-upgrade/" target="_blank" rel="nofollow noreferrer noopener">https://gtacknowledge.extremenetworks.com/articles/Solution/SNMP-communication-lost-after-EXOS-upgrade/</A> Thu, 20 Aug 2015 12:55:00 GMT https://community.extremenetworks.com/t5/extremeswitching-exos-switch/snmp-accees-after-15-5-4-2-patch1-5-upgrade/m-p/53160#M14872 Karthik_Mohando 2015-08-20T12:55:00Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/snmp-accees-after-15-5-4-2-patch1-5-upgrade/m-p/53161#M14873 Thank you!

Both lost access on SNMP. <BR /> <BR /> After I applied the remedy, the switches are reachable on SNMP but with delayed response which means switches are not able to process snmp polling from NMS.<BR /> <BR /> snmpMaster and snmpSubagent continue to eat CPU. See below output. CPU is 38.7% and major portion is occupied by snmp processes only which was 0 or 1% on earlier revision. <BR /> <BR /> Mem: 417428K used, 604064K free, 0K shrd, 110612K buff, 74888K cached<BR /> CPU: 38.7% usr 23.4% sys 0.0% nic 34.5% idle 0.0% io 3.1% irq 0.1% sirq<BR /> Load average: 11.23 9.90 9.26 11/213 1925<BR /> PID PPID USER STAT RSS %MEM CPU %CPU COMMAND<BR /> 1462 1 root S 5508 0.5 0 15.8 ./snmpSubagent <BR /> 1460 1 root S 4556 0.4 1 15.5 ./snmpMaster <BR /> 1458 1 root S 3088 0.3 0 5.7 ./cfgmgr <BR /> 1608 1 root S 2568 0.2 0 5.7 ./dot1ag <BR /> 1452 1 root S &lt; 14636 1.4 1 3.9 ./hal <BR /> <BR /> Question: As this is a known issue now, are we going to fix in coming EXOS releases? <BR /> <BR /> Delayed SNMP response and high CPU is a big concern for us.<BR /> <BR /> Thanks<BR /> Harkanwal <BR /> Fri, 16 Oct 2015 01:39:00 GMT https://community.extremenetworks.com/t5/extremeswitching-exos-switch/snmp-accees-after-15-5-4-2-patch1-5-upgrade/m-p/53169#M14881 Harkanwaljeet_S 2015-10-16T01:39:00Z
