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.
Difference in Console Port and Management Port –
|PARAMETER||CONSOLE PORT||MANAGEMENT PORT
|IP address Assignment||Can’t give IP address to console Port||IP address can be given to a management port
|Remote access via Telnet/SSH||No||Yes|
|Access required||Physical access to device required||IP reachability and TCP port 23 (for telnet) or TCP port 443 (for SSH) required or HTTP (80)
|Segregation type||Physically separate connection||Generally a VRF based traffic segregation
|Maximum Speed||0.1 Mbps (115200 bps) ||1 Gbps|
|Connectivity Type||Serial , DB9 , RJ45||RJ45|
|Management type||Out of Band Management||Out of Band Management
|Boot Sequence||Shows Boot sequence||Does not show boot sequence
|SNMP, Logging on interface||No SNMP, syslog configurable on console interface||SNMP, syslog configurable on management interface
|Application required||HyperTerminal||Telnet/SSH, Web GUI
|Additional Features ||The Console port supports these additional features: |
* Bit Rate 75, 110, 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600 and 115200 bit/s
|The Ethernet management port supports these features:
* Express Setup (only in switch stacks)
* Network Assistant
* Telnet with passwords
* Secure Shell (SSH)
* DHCP-based autoconfiguration
* SMNP (only the ENTITY-MIB and the IF-MIB)
* IP ping
* Speed—10/100/1000 Mbps and autonegotiation
* Loopback detection
* Cisco Discovery Protocol (CDP)
* DHCP relay agent
* IPv4 access control lists (ACLs)
