Problem with SNMP after put new release 3.8.8 Cisco vss 4500

[sistemas.p]

Hi averyone

i had the problem with the new release with 3.8.8 cisco WS-C4510R+E. After this update the allarm with "Nagios" go up, but the service working fine. I have more of 150 allarm conecting between Cisco and Nagios. But only 100 go up, and the 50 stay down.

I have configured the snmp like before : 

snmp-server community Publica RO

snmp-server community Privada RW

But the problem persists. I don't know if the problem is the new release  or in  Nagios i need to change somethig

Any idea what it can be?

THX all
