Management port overview
NOTE
The management port applies to FCX, SX 800, SX 1600, ICX 6430, and ICX 6450 devices.
The management port is an out-of-band port that customers can use to manage their devices without
interfering with the in-band ports. The management port is widely used to download images and
configurations, for Telnet sessions and for Web management.
For FCX devices, the MAC address for the management port is derived from the base MAC address of
the unit, plus the number of ports in the base module. For example, on a 48-port FCX standalone
device, the base MAC address is 0000.0034.2200. The management port MAC address for this device
would be 0000.0034.2200 plus 0x30, or 0000.0034.2230. The 0x30 in this case equals the 48 ports on
the base module.
For SX 800 and SX 1600 devices, the MAC address for the management port is derived as if the
management port is the last port on the management module where it is located. For example, on a 2 X
10G management module, the MAC address of the management port is that of the third port on that
module.

How the management port works

The following rules apply to management ports:
• Only packets that are specifically addressed to the management port MAC address or the broadcast
MAC address are processed by the Layer 2 switch or Layer 3 switch. All other packets are filtered
out.
• No packet received on a management port is sent to any in-band ports, and no packets received on
in-band ports are sent to a management port.
• A management port is not part of any VLAN
• Configuring a strict management VRF disables certain features on the management port.
• Protocols are not supported on the management port.
• Creating a management VLAN disables the management port on the device.
• For FCX and ICX devices, all features that can be configured from the global configuration mode can
also be configured from the interface level of the management port. Features that are configured
through the management port take effect globally, not on the management port itself.
For switches, any in-band port may be used for management purposes. A router sends Layer 3 packets
using the MAC address of the port as the source MAC address.
For stacking devices, (for example, an FCX stack) each stack unit has one out-of band management
port. Only the management port on the Active Controller will actively send and receive packets. If a new
Active Controller is elected, the new Active Controller management port will become the active
