SNMP Modular Example

Hi,

Would it be possible for someone who has this working to show an example please. I'm not too familiar with SNMP MIBs and OIDs etc but I would like to poll Cisco switches to get interface name and utilization figures out of them.

Thanks for any help.

You may be able to use the following OIDs from the "Interface MIB" (IF-MIB) for polling the Cisco switch interface utilization.

Inbound

1.3.6.1.2.1.2.2.1.10

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?objectInput=1.3.6.1.2.1.2.2.1.10&translate=Trans...

Outbound

1.3.6.1.2.1.2.2.1.16

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?objectInput=1.3.6.1.2.1.2.2.1.16&translate=Trans...

And the setup for the SNMP Modular Input stanza would be quite simple :

Example of configuration from inputs.conf

[snmp://my_cisco_switch]
destination = myswitchhostname
do_bulk_get = 1
ipv6 = 0
listen_traps = 0
mib_names = IF-MIB
object_names = 1.3.6.1.2.1.2.2.1.10,1.3.6.1.2.1.2.2.1.16
snmp_version = 2C
sourcetype = foo
index = foo
split_bulk_output = 0
disabled = 0
