Internal Ethernet devices
During the switch initialization process, a new internal Ethernet device is created. The devices
created are inbd0 and inbd1. Ethernet device inbd0 is used to communicate through GE port 1 and
inbd1 is used to communicate through GE port 0. These new Ethernet interfaces are internal only
and are not accessible from outside the switch. They are used strictly for communicating IP packets
between the CP and the GE port processor.

shows the Inband Management process. During initialization, the hardware addresses
for inbd0 and inbd1 are initialized to create a hardware address that is unique for each Ethernet
interface. After the Ethernet device is initialized, it is enabled for use. At this point, the Ethernet
device can start sending and receiving Ethernet frames.

Inband Management process
The NAT IP table is loaded and automatically configured on startup.The source address NAT is
configured on the Inband Management interfaces to use the address of the CP management
interface (eth0). The switch automatically uses the IP address of the CP management interface for
the source address NAT for the new Inband Management interfaces, so no additional configuration
is required.

IP address and routing management
The CP and GE port processor Ethernet interfaces must have IP addresses associated with them.
By default, there will be no IP addresses associated with these new Ethernet interfaces. To manage
the IP addresses for the CP and GE port processor Ethernet interfaces, use the portCfg
inbandmgmt command on the CP.

Specifying the portCfg inbandmgmt command with the
routeadd or routedel options adds and
deletes route entries to and from the CP and the GE port processor routing tables. IP addresses
must be configured for both devices prior to configuring any routes. When configuring the routes for
the CP, the GE port processor inband device address for that GE port is used instead of the
