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 S6000 platform.
The chapter contains the following sections:
• SNMP Commands
• Syslog Commands
SNMP Commands
The following SNMP commands are available in the Dell Networking operating software.
The simple network management protocol (SNMP) is used to communicate management information
between the network management stations and the agents in the network elements. Dell Networking OS
supports SNMP versions 1, 2c, and 3, supporting both read-only and read-write modes. Dell Networking
OS sends SNMP traps, which are messages informing an SNMP management system about the network.
Dell Networking OS 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.
• If you want to query an E-Series switch using SNMP v1/v2/v3 with an IPv6 address, configure the IPv6
address on a non-management port on the switch.
• If you want to send SNMP v1/v2/v3 traps from an E-Series using an IPv6 address, use a non-
management port.
• 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).
