Hi

I can't get the snmp to work on my cisco ASR9000 to monitor it with
Centreon.

i use this configuration:

snmp-server ifindex persist
snmp-server trap-source Loopback0

snmp-server view public system included
snmp-server community public view public ro admin-nets

snmp-server group SnmpAdmins v3 auth ipv4 admin-nets
snmp-server user admin SnmpAdmins v3 auth md5 **PASSWORD

ipv4 access-list admin-nets
permit ipv4 172.20.18.0/28 any
...

when I run the check requests on my centreon, in snmp v3 with login / pass
I always have a "no answer"

I did not find an example configuration in version 2c

a idea ?

thanks for your help
olivier

Have you updated your 'control-plane' config to allow SNMP from your
sources?

Hi Oliver,

This is off the top of my head, so not perfect, but you need something
like this...

control-plane
management-plane
inband
interface XXX
allow SNMP peer
address ipv4 172.20.18.0/28

Have tried the various debug commands to see why your packets are
being dropped? If not, add the control-plane rule above, then run some
debugs and report back to the list what you see in the logs.

Cheers,
James.
