Simple Network Management Protocol
(SNMP)
The Simple Network Management Protocol (SNMP) is designed to manage devices on IP networks by
monitoring device operation, which might require administrator intervention.
NOTE: On Dell Networking routers, standard and private SNMP management information bases
(MIBs) are supported, including all Get and a limited number of Set operations (such as
set vlan
and
copy cmd
).
Protocol Overview
Network management stations use SNMP to retrieve or alter management data from network elements.
A datum of management information is called a managed object ; the value of a managed object can be
static or variable. Network elements store managed objects in a database called a management
information base (MIB).
MIBs are hierarchically structured and use object identifiers to address managed objects, but managed
objects also have a textual name called an
object descriptor .
Implementation Information
The following describes SNMP implementation information.
• Dell Networking OS supports SNMP version 1 as defined by RFC 1155, 1157, and 1212, SNMP version 2c
as defined by RFC 1901, and SNMP version 3 as defined by RFC 2571.
• Dell Networking OS supports up to 16 trap receivers.
• Dell Networking OS implementation of the sFlow MIB supports sFlow configuration via SNMP sets.
• SNMP traps for the spanning tree protocol (STP) and multiple spanning tree protocol (MSTP) state
changes are based on BRIDGE MIB (RFC 1483) for STP and IEEE 802.1 draft ruzin-mstp-mib-02 for
MSTP.
SNMPv3 Compliance With FIPS
SNMPv3 is compliant with the Federal information processing standard (FIPS) cryptography standard. The
Advanced Encryption Standard (AES) Cipher Feedback (CFB) 128-bit encryption algorithm is in
compliance with RFC 3826. SNMPv3 provides multiple authentication and privacy options for user
configuration. A subset of these options are the FIPS-approved algorithms: HMAC-SHA1-96 for
authentication and AES128-CFB for privacy. The other options are not FIPS-approved algorithms because
of known security weaknesses. The AES128-CFB privacy option is supported and is compliant with RFC
3826.
