29 Management Networks for Dell EMC Networking
Access to the GUI is obtained by entering the IP address of the managed device into the URL field of the
browser. The syntax is http(s)://switch_mgmt_ip. Figure 14 shows an example of a GUI management
screen. This GUI shows a picture of the switch. Green indicates that ports 1 and 2 are up.
The GUI is a quick way to find and implement features available on a switch, without the need or
understanding of CLI commands. Once a switch is configured through the GUI, the administrator can view the
configuration from the CLI to see what commands were added or changed. This can be used to assist the
administrator in learning the CLI commands.
7.3 Simple Network Management Protocol
Simple Network Management Protocol, or SNMP, is an application-layer protocol for configuring and
monitoring switches and other devices on the network. Each switch uses a database called a management
information base (MIB). The MIB contains hundreds of data points called object identifiers, or OIDs. Some of
the OIDs are read-only, such as the System Identifier, while others are read/write by the network
administrator. Some OIDs are modified by the switch itself, for example, a temperature OID, while others are
modified by the network administrator, such as a port-channel.
Each switch uses a different set of MIBs that are customized for that switch. Dell EMC updates MIB files at
the same time their associated firmware files are updated. For this reason, MIBs are available from the same
download page on the Dell EMC Support page or are included in the zipped firmware package.
OpenManage Network Manager (OMNM) is a one-to-many management tool based primarily on SNMP.
OMNM allows network administrators to work with many switches on the network at one time. CLI and Web
GUI interfaces only allow you to manage one switch at a time. Use OMNM to configure, manage, monitor,
inventory, backup, and restore several Dell EMC switches at once.
