Management Port vs Console Port in Networking Devices

Management port vs Console port

Management Port vs Console Port

Device management is essential in device provisioning, implementation, operations and configuration changes. Inband and out of band (OOB) are 2 management approaches administrators may consider. While OOB management operates on a “management plane” that is separate from the data plane used by data traffic on the device, in-band management traffic uses the same data plane as used by data traffic.

Hence OOB management can continue to function even during the event of data traffic congestion, device glitch or network attacks in addition to improved switch security.

Console port and dedicated Management port are 2 types of OOB management scenarios. Please note that Console and Management ports support non-transitive traffic and hence can’t be configured.
