Display signal from Ubnt airmax devices

RouterOS The Dude

Hello,

I have noticed that old ubnt non-airmax devices are reporting signal strength, but new airmax devices don’t have signal strength on links between them. It reports ssid, and speed, but no signal. How to overcome this?

Thanks…

probably the OID has changed. you need to find out the new OID

I have found new OID. Now, how to change it. I tried to put it manually in “appearance”, but it would be hard to do it for all the devices. New OID that i found is [oid(“1.3.6.1.4.1.14988.1.1.1.1.1.4.5”)]

This is why I put every wireless device on a single map. You can’t modify the appearance of a device but you can only modify the appearance globally or on each map (so my wireless map appearance has a couple changes to it). Note: I am using Cisco access points which are not handled natively by the dude. Also you can easily modify the global appearance and OIDs that you add here will only show up on devices that populate them. It is only one more SNMP read. I would not put hundreds of OIDs on global appearance but a few wont hurt.

It would be nice if appearance was also controlled by device type.

HTH,

Snmp is very strange to me, but i found out that oid has changed from

1.3.6.1.4.1.14988.1.1.1.1.1.4.6
to
1.3.6.1.4.1.14988.1.1.1.1.1.4.5

Can that somehow help anyone to help me to again see signal strength in dude without any hardcore modification?

I opened “snmp_wireless_link_info” function, but i can’t figure how to change anything.

Please help…

I’ll take a look tomorrow.

the snmp_wireless_link_info has iso.org.dod.internet.private.enterprises.mikrotik.mikrotikExperimentalModule.mtXRouterOs.mtxrWireless.mtxrWlStatTable.mtxrWlStatEntry.mtxrWlStatSsid which is probably 1.3.6.1.4.1.14988.1.1.1.1.1.4.6

If that is true iso.org.dod.internet.private.enterprises.mikrotik.mikrotikExperimentalModule.mtXRouterOs.mtxrWireless.mtxrWlStatTable.mtxrWlStatEntry.mtxrWlStatSs
could be replaced by 1.3.6.1.4.1.14988.1.1.1.1.1.4.5

So instead of
concatenate(
“iso.org.dod.internet.private.enterprises.mikrotik.mikrotikExperimentalModule.mtXRouterOs.mtxrWireless.mtxrWlStatTable.mtxrWlStatEntry.mtxrWlStatSsid.”,link_index()
), 300, 600)),

You would change it to this…
concatenate(“1.3.6.1.4.1.14988.1.1.1.1.1.4.5.”,link_index()
), 300, 600)),

Where ever the old one is used…

Note: You can use OIDs directly in the dude, you don’t have to have the MIB as long as the correct values are read.

You will be way better off cloning the probes and functions and not modifying the originals.

BACKUP your dude folder if you are using windows.
