SNMP Ping MIB?

[Keyan]

What MIB is used for just an Up/Down SNMP ping? Is the same across all cisco devices? How do I limit a specfic read-only string so it can only access that MIB?

TIA

You may poll sysUpTime (1.3.6.1.2.1.1.3) and if the number decreased, then the device reloaded.

If it doesn't respond, then snmp communication is failing.

To set up snmp views, you may use the example at this link:

This helps. A couple of additional questions though.

Do I have to exclude all of the MIBs I don't want the device to be able to see? Or if I only include two MIBs will all others be excluded?

Can views be set up on CAT OS devices?

You can try putting snmp-server view cutdown internet exclude (that will remove everything other than the ones that are included)

Yes, views are supported in CatOS (set snmp view)
