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
management port. In this situation, the MAC address of the old Active Controller and the MAC address
of the new controller will be different.
CLI Commands for use with the management port
The following CLI commands can be used with a management port.
To display the current configuration, use the show running-config interface management
command.
Syntax: show running-config interface management num
device(config-if-mgmt)#ip addr 10.44.9.64/24
device(config)#show running-config interface management 1
interface management 1
ip address 10.44.9.64 255.255.255.0
To display the current configuration, use the show interfaces management command.
Syntax: show interfaces management num
device(config)#show interfaces management 1
