Dell Switch Monitoring
To monitor Dell Switch devices, SNMP access is all that is required. If the LogicModules do not automatically apply to the device, review the following troubleshooting steps:
- SNMP is not set up on the device. There should be a configuration line such as "snmp-server community public RO" that will enable the SNMP daemon.
- The SNMP community string configured in LogicMonitor is not correct for the device. To configure this, please refer to Defining Properties and Authentication Credentials.
- The device may have an entry in the snmp-server configuration which restricts the IP addresses that it will respond to. For example, an snmp-server configuration line in the form "snmp-server community public RO 2" would inclusively restrict SNMP responses to addresses included in access-list 2. In this case, the IP address of the Collector would have to be permitted by adding it to access-list 2.
- There is a firewall—either on the device itself, applied to one of the interfaces, or a separate device between the LogicMonitor Collector and the switch—that is preventing SNMP traffic on port 161 UDP. For devices that require SNMP trap traffic to function, port 162 UDP may need to be unrestricted as well.
Dell PowerConnect devices also fall under the Dell Switch category and are their configurations are similar.
Supported Dell Switches:
- Dell Networking N2XXX, N3XXX, N4XXX
