It doesn't look like there's much to do in this situation. I checked with the product manager and he agrees and this post Re: Cisco VPN Tunnel Status - SNMP? much the same thing. Is there a way to ensure that the OID does not change?
Sorry bout this,
You could do a get table on 220.127.116.11.4.1.22918.104.22.168.2.1.5. This would return both the .1 and .2 OIDs and you could display the “table” on the website. You might even be able to alert on it ok.
This assumes that there’s nothing under 22.214.171.124.4.1.229126.96.36.199.2.1.5 but the mutually-exclusive .1 and .2 OIDs. If there’s a bunch of other stuff going on at .3, .4, .5, etc., then this won't work
