7 Management Networks for Dell EMC Networking
Management network selection
There are three management network methods that are commonly used for deploying and managing
switches, servers, and other devices on the network: console, out-of-band Ethernet, and in-band Ethernet.
The method that is used is based largely on the existing architecture, preference, budget, or a combination of
these factors. If a management network is already in place and working satisfactorily, there is little else to do.
The planning or budgeting of a green field network, or the addition to an existing management infrastructure
in a brown field network, can prompt questions regarding the method of management to use. This guide helps
you decide which method(s) should be used and the process that is required to set up the management
network.
The following should be considered when deciding which management network(s) is best for your
environment and budget:
• New or existing production network
• Accessibility of the management network when the production network is down
• Ability to connect to management network over IP: SSH, Telnet, HTTPS, HTTPS
• Ability to connect and view logs of production switches while they are booting
• Security
• Budget concerns
Table 2 shows a comparison between the commonly used management networks, each with pros and cons.
This information may be used in deciding which management network(s) is best for your environment and
budget.
Comparison of Management Network Methods
Console management
OOB Ethernet management
In-band Ethernet management
Pros
• Ideal for new configurations
• Always accessible if power is on
• Operates during POST
• View logs during boot
• Independent network
• Can be accessible when
the production network is
down
• SSH and Telnet support
• HTTP and HTTPS support
• Allows for ACLs for identity
and security
• Uses existing equipment
• SSH and Telnet support
• HTTP and HTTPS support
• Allows for ACLs for identity
and security
Cons
• Requires extra equipment for
one-to-many management
• No SSH or Telnet support
• No HTTP or HTTPS support
• Slower file transfers/upgrades
• Dedicated console cabling,
dongle, and driver installation
• Embedded USB driver
installation
• Requires additional
dedicated switches
• Requires extra cabling
• Dedicated management
ports not available on all
switches
• May go down along with the
production network
• Requires use of production
network ports
• Requires use of production
network bandwidth
• Dedicated management
ports are left unused
Implementing two or more methods can complement each other and enable network administrators the
flexibility of choosing where to deploy each.
