Command Line Reference Guide

Simple Network Management Protocol (SNMP)

and Syslog

This chapter contains commands to configure and monitor the simple network management protocol (SNMP) v1/v2/v3

and Syslog. Both features are supported on the S5000 switch.

The chapter contains the following sections:

• SNMP Commands

• Syslog Commands

SNMP Commands

The following SNMP commands are available in the Dell Networking operating software (FTOS).

The simple network management protocol (SNMP) is used to communicate management information between the

network management stations and the agents in the network elements. FTOS supports SNMP versions 1, 2c, and 3,

supporting both read-only and read-write modes. FTOS sends SNMP traps, which are messages informing an SNMP

management system about the network. FTOS supports up to 16 SNMP trap receivers.

Important Points to Remember

• Typically, 5-second timeout and 3-second retry values on an SNMP server are sufficient for both LAN and WAN

applications. If you experience a timeout with these values, the recommended best practice on Dell Networking

switches (to accommodate their high port density) is to increase the timeout and retry values on your SNMP

server to the following:

– SNMP Timeout—greater than 3 seconds.

– SNMP Retry count—greater than 2 seconds.

• SNMP v3 informs are not currently supported with IPv6 addresses.

• If you are using access control lists (ACLs) in an SNMP v3 configuration, group ACL overrides user ACL if the

user is part of that group.

• SNMP operations are not supported on a virtual local area network (VLAN).
