supports both centralized and distributed network management
strategies. It includes improvements in the Structure of Management
Information (SMI) and adds some security features.
v3 – Specifies that the SNMP version 3 is to be used. SNMP v3
provides secure access to devices through a combination of
authentication and encrypting packets over the network. SNMP v3
adds:
• Message integrity − Ensures that packets have not been
tampered with during transit.
• Authentication − Determines if an SNMP message is from a
valid source.
• Encryption − Scrambles the contents of messages to
prevent it from being viewed by an unauthorized source.
noauth_nopriv − Specifies that there is no authorization and no
encryption of packets sent between the Switch and a remote SNMP
manager.
auth_nopriv − Specifies that authorization is required, but there is no
encryption of packets sent between the Switch and a remote SNMP
manager.
auth_priv − Specifies that authorization is required, and that packets
sent between the Switch and a remote SNMP manger are
encrypted.
read_view – Specifies that the SNMP group being created can
request SNMP messages.
• <view_name 32> − A string of up to 32 objects that a remote
SNMP manager is allowed to access on the Switch.
write_view – Specifies that the SNMP group being created has write
privileges.
• <view_name 32 identifies the group of MIB objects that a
remote SNMP manager is allowed to access on the Switch.
notify_view − Specifies that the SNMP group being created can
receive SNMP trap messages generated by the Switch’s SNMP
agent.
• <view_name 32> − A string of up to 32 alphanumeric
characters that identifies the group of MIB objects that a
remote SNMP manager is allowed to access on the Switch.

notify_view sg1
Command: create snmp group sg1 v2c read_view sg1 write_view sg1 notify_view
