The community string and version is different for two switch

Basically i want to monitor switch2 from nagios server , i have given community string and version of switch2 but still i am not able to monitor switch2

i am getting error :
No ports were detected on the switch

1) Switch is ON and pingable
2) Switch SNMP is enabled
3) Switch IP is proper

Once again we are going to need a bit more information, how are you trying to monitor this switch? Via a custom plugin, or via the Switch / Router Monitoring Wizard?

Through switch router monitoring

What kind of a switch is this? There are certain switches that do not store port information at the same oids that mrtg is expecting, and we may have to do some digging.

HI,

It's a CISCO Switch .

i tried this
nmap -sU -p 161 Ip address of switch

#nmap -sU -p 161 10.187.210.13

Starting Nmap 5.21 ( http://nmap.org ) at 2013-07-24 02:42 IST
Nmap scan report for 10.187.210.13
Host is up (0.00082s latency).
PORT STATE SERVICE
161/udp open snmp

Nmap done: 1 IP address (1 host up) scanned in 11.38 seconds

Thanks,

Specifically, what make and model? while cisco is generally supported, there are some that have issues, especially stacked switches.

hi,

the same switch is being monitored by different tools and its not the stacked switch as you said

Thanks

What tools are you using? They could be querying different oids than mrtg is set to use. I must ask, are you being intentionally vague, as without detailed information especially for snmp, it is extremely difficult to work with and get a resolution for you.

Hi,

Can you send me the list of details required for troubleshooting the issue as i can send the questions to client and get back to you.

They are using some free tools to monitor the switch. they asically want to shift to nagiosxi.

Thanks,

Can you snmpwalk the switch? Or run an snmpget on the proper OID?
