SNMPv1 and SNMPv3.
File transfer protocols.
Security Access Description
Available methods (SNMPv1):
• Community Name
• Host Name
• NMS IP filters
• Agents that can be enabled
or disabled
• Four access communities
with read/write/disable
capability
For both SNMPv1 and SNMPv3, the host name restricts access
to the Network Management System (NMS) at that location
only, and the NMS IP filters allow access only to the NMSs
specified by one of the IP address formats in the following
examples:
• 159.215.12.1: Only the NMS at the IP address 159.215.12.1.
• 159.215.12.255: Any NMS on the 159.215.12 segment.
• 159.215.255.255: Any NMS on the 159.215 segment.
• 159.255.255.255: Any NMS on the 159 segment.
• 0.0.0.0 or 255.255.255.255: Any NMS.
SNMPv3 has additional security features that include the
following:
• An authentication passphrase to ensure that an NMS trying to
access the Rack PDU is the NMS it claims to be.
• Encryption of data during transmission, with a privacy
passphrase required for encrypting and decrypting.
Available methods (SNMPv3):
• Four User Profiles
• Authentication through an
authentication passphrase
• Encryption through a privacy
passphrase
• SHA or MD5 authentication
• AES or DES encryption
algorithm
• NMS IP filters
Security Access Description
Available methods:
• User name and password
• Selectable server port
• FTP Server and access
protocols that can be
enabled or disabled
• Secure CoPy (SCP)
With FTP, the user name and password are transmitted as
plain text, and files are transferred without encryption.
Use SCP to encrypt the user name and password and the files
being transferred, such as firmware updates, configuration
files, log files, Secure Sockets Layer (SSL) certificates, and
Secure SHell (SSH) host keys. If you choose SCP as your file
transfer protocol, enable SSH and disable FTP.
