SNMP Commands

The following SNMP commands are available in the Dell EMC Networking OS.

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 EMC Networking OS supports SNMP versions 1, 2c, and 3, supporting both read-only and read-write modes. Dell EMC Networking OS sends SNMP traps, which are messages informing an SNMP management system about the network. Dell EMC 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 EMC 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).
