Upgraded IP SLA on 5 pollers early AM Upgrade process had no discernible glitches. Doesn't look like I am missing any operations and all seem to be recording properly. took maybe 10 minutes per poller
That's Great! Thanks for the feedback!
Just tried the discovery feature, need an explanation of what/how it discovers. I have about 20 device configured fro IP SLA but it found over 161 devices. Unless another engineer has been playing with IP SLA and not telling me. Also when it does the discovery it said the R/W snmp string was wrong, i can accept that as we had to many people making them up but I added a standard R and R/W string to all devices and left the old ones as I don't wan to take a change on breaking any some old tools still in place or those used by our external monitoring service. So the question is 1) if a device is already configured fro IP SLA why the R/W necessity, it should not have to write any thing to the device? 2) does the discovery look at all the strings or just the first it 'sees' ?
The discovery feature is basically looking at your Orion Cisco devices and checking for a couple of things. We check if you valid SNMP read strings, then we check for a specific OID that tells if the device is IP SLA capable.
To answer your first question, IP SLA Manager communicates with the device via SNMP. Valid write strings are required for IP SLA Manager to be able to create operations on those devices. If you just want to monitor existing operations, you only need a valid read string.
To answer your second question, the discovery feature takes whatever SNMP community strings you've provided for that device.
HTH,
