SNMP trap and informs

[incognito]

Hello

is there anyone who can explain me:

1) SNMP trap and informs (the difference/similarity between them etc)?

2) And how to configure SNMPv3 on nexus switch? Or please explain me SNMP in general or can you give me a link to a good explained guide?

3) Do I have to configure SNMP community when I'm going to use only SNMP v3?

Oh ok.
If I want a certain group to have full read write permissions, what exactly does the write part mean? Does that mean they can send GET messages to view whatever data they want?

A SNMP view is an object which explicitly permits or denies access to specified OIDs.

In absence of a read view being specified under the snmp-server group command the default read view will be used which will grant read (GET) access to all OIDs.

If a write view is explicitly configured then a user member of the snmp-server group will have SET permissions to the specified OIDs.

cheers,

Seb.
