SNMP timeout even through localhost
Hello Devs!
I have a 5250 appliance that for some odd reason is not responding to SNMP!
Current config is as follows:
root@(bigip1)(cfg-sync Standalone)(Active)(/Common)(tmos) list sys snmp
sys snmp {
agent-addresses { tcp6:161 udp6:161 }
allowed-addresses { 127. 10.10.10.182 }
communities {
test {
community-name mycommunity
source default
}
}
disk-monitors {
root {
minspace 2000
path /
}
var {
minspace 10000
path /var
}
}
process-monitors {
bigd {
process bigd
}
chmand {
process chmand
}
httpd {
max-processes infinity
process httpd
}
mcpd {
process mcpd
}
sod {
process sod
}
tmm {
max-processes infinity
process tmm
}
}
sys-contact nobody
sys-location someplace
}
root@(bigip1)(cfg-sync Standalone)(Active)(/Common)(tmos)
When the host tryes to do a snmp get, it timeouts. I can see the get coming in but big-ip never answers it...

I even tryed doing a snmpwalk from localhost but it also didn't work.
[root@bigip1:Active:Standalone] config snmpwalk -v 2c -c mycommunity 127.0.0.1 .
Timeout: No Response from 127.0.0.1
[root@bigip1:Active:Standalone] config
Doing 'bigstart restart snmpd' didn't solve the issue either. The only suspicious thing I have found is this log message on /var/log/daemon.log:
[root@bigip1:Active:Standalone] config grep snmp /var/log/daemon.log
Nov 7 18:19:01 bigip1 warning snmpd[5271]: Warning: no access control information configured. (Config search path: /usr/share/snmp) It's unlikely this agent can serve any useful purpose in this state. Run "snmpconf -g basic_setup" to help you configure the snmpd.conf file for this agent.
Any ideas of what to do next? I really don't want to reload this box since it is not part of a cluster...
Thanks! Rafael
