SFTOS SNMP support conforms to RFC 1157 (SNMP v1), RFC 1213 (SNMP v2 (MIB-II)), and RFC
2570 (SNMP v3). For more on the MIBs and SNMP-related RFCs supported by SFTOS, refer to the
SNMP appendix to this guide (see RFCs, MIBs, and Traps on page 285). That appendix also discusses the
SNMP traps that SFTOS generates.
The MIB files are on the S-Series product CD-ROM and on the iSupport website (password required):

As a best practice, Dell Force10 recommends polling several SNMP object IDs (OIDs), as described here.
SNMP is especially valuable in certain cases — for example when a console connection is unavailable.
All MIBs listed in the output of the
show sysinfo command for a particular SFTOS image can be polled.
Specifically, the S50 supports counter MIBs, including the 32-bit and 64-bit IF-MIB and IP-MIB
(accessing 64-bit counters requires SNMPv2c); hardware-related MIB variables, such as the Inventory
MIB and Entity MIB; protocol-related MIBs, such as OSPF and VRRP; Layer 2 MIBs, such as the
F10OS-SWITCHING-MIB; Layer 3 MIBs, such as F10OS-ROUTING-MIB, and the RMON MIB.
For general MIB queries, the OIDs start from 1.3.6.1.2.1. For private MIB queries, the OIDs start from
1.3.6.1.4.1.6027.1, where 6027 is the Dell Force10 Enterprise Number.
This section provides basic configuration steps for enabling SNMP.
Other commands that configure the SNMP server connection include:
•
snmp-server: Sets the name and the physical location of the switch, and the organization responsible
for the network.
•
snmp-server community ipaddr: Sets a client IP address for an SNMP community.
Command Syntax Command Mode Usage
interface managementethernet Global Config Access the Interface Managementethernet mode in order to
configure a management IP address, which is required for
SNMP management. For details, see Setting up a
Management Connection to the Switch on page 28.
[no] snmp-server community
community-name
Global Config Identify an SNMP community for the switch to join. Dell
Force10 suggests that you use the same community name for
all chassis that you will manage with your SNMP
management system. If you have previously entered a string
for another SNMP manager and agent, use the existing
string.
[no] snmptrap name ipaddr
Global Config Adds an SNMP trap receiver name and IP address to the
SNMP community. The maximum name length is 16
case-sensitive alphanumeric characters.
[no] snmp-server enable trap
violation
Interface Config
or
Interface Range
Optionally, enable the sending of new violation traps for a
specified interface designating when a packet with a
disallowed MAC address is received on a locked port.
Except for this trap, all traps are enabled by default. For
details on trap options, see Managing SNMP Traps on
page 73, below.
