Message Digest 5 [MD5] algorithms) and encryption (Data Encryption Standard
[DES] as the default and AES), to ensure secure communication between NMS station
and NX-OS. Both mechanisms are implemented, as shown in Example 1-8.
Because NX-OS is truly modular and highly available, the NX-OS implementation of SNMP
supports stateless restarts for SNMP. NX-OS has also implemented virtualization support
for SNMP; NX-OS supports one instance of SNMP per VDC. SNMP is also VRF-aware,
which enables you to configure SNMP to use a particular VRF to reach the network
management host.
Example 1-8 demonstrates how to enable SNMPv3 on NX-OS.
