On the Nexus 4000, how can I configure SNMP to block  polling of the Entity MIB??

N4K PFMA Crash During SNMP Walk of "Entity Type Phy PS Fan" MIB

Symptom: Nexus 4k switch crashes during SNMP polling of the Entity MIB (1.3.6.1.2.1.47).Conditions: SNMP polling enabledWorkaround: Disconnect the 4k from the SNMP server. Block the offending MIB.

This workaround was more theoretical than actual.  NX-OS does not allow for SNMP Views like IOS does.  We are in the process of updating this bug to remove that statement.  However, the fixed version of code for the N4K is now available at http://software.cisco.com/download/release.html?mdfid=282819252&flowid=3091&softwareid=282088129&release=4.1(2)E1(1i)&relind=AVAILABLE&rellifecycle=&reltype=latest .  Sorry for the confusion.

[Bill CARTER]

The latest version available is 4.1(2)E1(1i) which I am running and was released 13-July-2012.

Sorry, Bill.  I misread the bug details.  The bug said the fixed version was 'j', and I read that as an 'i'.    Given that, the only workaround is to prevent, from the NMS, polling of the ENTITY-MIB.  I realize this is difficult to do without fully unmanaging the device

If only i knew it before.

Just happened in my critical server while being discovered using DCNM 6.1
