Hi,
Please help! I've been beating my brains out trying to config a router 10.10.1.2 to receive and send snmp packets/traps with a Nagios server 192.168.1.2 , using these instructions:
http://www.cisco.com/c/en/us/td/docs/wireless/access_point/12-3_7_JA/configuration/guide/i1237sc/s37snmp.html
On the Nagios server 192.168.1.2 (Centos 6.4) I tried these commands and got nothing:
[root@tamaras-nagios ~]# snmpwalk -Os -c public -v 1 10.10.1.2
Timeout: No Response from 10.10.1.2
[root@tamaras-nagios ~]# snmpget -mALL -v2c -cpublic 10.10.1.2 all
Timeout: No Response from 10.10.1.2.
Also, traps aren't being received :-( There is a firewall between the two, but I've gone over its rules and there shouldn't be a problem. There's a ping from the Nagios to the Router and vice versa.
The Nagios works fine with other stations and network devices, so I imagine I've missed something in the router config. I'm going for a v2c snmp config but I don't mind v1 if it'll work.
These are the router specs:
Cisco IOS Software, 7200 Software (C7200-ADVENTERPRISEK9-M), Version 15.0(1)M, RELEASE SOFTWARE (fc2)
BOOTLDR: Cisco IOS Software, 7200 Software (C7200-KBOOT-M), Version 12.2(25)S9, RELEASE SOFTWARE (fc1)
(some chosen lines from the running config):
access-list 18 permit 192.168.1.2
snmp-server community public RO
snmp-server community ronni RW
snmp-server enable traps snmp authentication linkdown linkup coldstart warmstart

snmp-server enable traps ds1
snmp-server enable traps call-home message-send-fail server-fail
snmp-server enable traps tty
snmp-server enable traps gatekeeper
snmp-server enable traps eigrp

(all the snmp traps are enabled so I won't paste the whole list)
