BigIron RX(config)# show snmp server
Syntax: show snmp server
NOTE
If display of the strings is encrypted, the strings are not displayed. Encryption is enabled by default.

Using the user-based security model

SNMP version 3 (RFC 2570 through 2575) introduces a User-Based Security model (RFC 2574) for
authentication and privacy services.
SNMP version 1 and version 2 use community strings to authenticate SNMP access to
management modules. This method can still be used for authentication. In SNMP version 3, the
User-Based Security model of SNMP can be used to secure against the following threats:
•
•
•
•
Furthermore, SNMP version 3 supports View-Based Access Control Mechanism (RFC 2575) to
control access at the PDU level. It defines mechanisms for determining whether or not access to a
managed object in a local MIB by a remote principal should be allowed. (Refer to

NOTE
SNMP version 3 Notification is not supported at this time. The system will generate traps in SNMP
version 1 format.
NOTE
SNMP may timeout when trying to get module temperature values. You must increase the timeout
value to 10 seconds to prevent a timeout.
