Cisco Standard


Cisco develops, manufactures and sells networking hardware, software, telecommunications equipment and other high-technology services and products

Plugin-pack assets​

Monitored equipments​

All Cisco devices supporting standard MIBs can be monitored:

  • Routers
  • Access Points
  • Switchs
  • ...

Discovery rules​

Rule nameDescription
App-Protocol-SNMP-HostDiscoveryDiscover your Cisco devices through a SNMP subnet scan

Collected metrics​

Only standard metrics are described in this section. Be aware that a lot of other checks and metrics are available from Cisco additionnal MIBS. Here is a non-exhaustive list:

  • hsrp: HSRP protocol state
  • ipsectunnel: State of ipsec tunnels
  • ipsla: IP SLA configuration and performances
  • load: Load of your device cores
  • memoryflash: Memory flash pool usage
  • qosusage: Check QOS configuration and associated consumptions
  • stack: Check the health of your device stack

Cisco device configuration​

To use this pack, the SNMP service must be properly configured on your Cisco device. Cisco provides an official documentation to achieve this:

Here is an example:

  • Connect to your router and reach the configuration prompt:
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
  • Use this command to enable snmp-server and set a read-only community
Router(config)#snmp-server community public RO 

In the example above, 'public' is your snmp community. You do now want to use it in production ;)

Network flow​

Your centreon server must be able to reach the Cisco device over UDP/161 SNMP port.


  1. Install the Cisco SNMP Centreon Plugin on every poller expected to monitor Cisco devices:
yum install centreon-plugin-Network-Cisco-Standard-Snmp
  1. Install The 'Cisco-Standard-Snmp' Centreon Plugin-Pack from the "Configuration > Plugin packs > Manager" page


When creating an host, fill the 'Snmp Community' and 'Snmp Version' fields to match the device configuration.

When using SNMP v3, use the SNMPEXTRAOPTIONS Macro to add specific authentication parameters More information in the Troubleshooting SNMP section.

SNMPEXTRAOPTIONSConfigure your own SNMPv3 credentials combo


How do I test my configuration through the CLI and what do the main parameters stand for ?​

Once the Centreo plugin installed, you can test it logging with the centreon-engine user:

/usr/lib/centreon/plugins// \
--plugin=network::cisco::standard::snmp::plugin \
--mode=cpu \
--hostname= \
--snmp-version='2c' \
--snmp-community='test/cisco' \

The command above checks the CPU utilization of your Cisco box (--mode=cpu). You must always define the IP address of the device (--hostname= as well as the SNMP versions and community (--snmp-version='2c' --snmp-community='test/cisco')

You can display all modes that come with the plugin with the command below:

/usr/lib/centreon/plugins// \
--plugin=network::cisco::standard::snmp::plugin \

You can display options of a specific mode by using the --help flag. Here is an example to display cpu mode parameters:

/usr/lib/centreon/plugins// \
--plugin=network::cisco::standard::snmp::plugin \
--mode=cpu \

UNKNOWN: SNMP GET Request : Timeout​

This message generally means that you are not using the right snmp version or community. It could also indicate that a third-party device like a firewall is blocking the SNMP UDP/161 request.

UNKNOWN: SNMP GET Request : Cant get a single value.​

This error message often refers to the following issues:

  • the Cisco device doesn't support the MIB used by the plugin
  • the targeted SNMP OID cannot be fetched because of insufficient privileges on the device
