The Management Network
The GbE2c is an integral subsystem within the overall BladeSystem. The BladeSystem chassis
includes an Onboard Administrator as the central element for overall chassis and control. The
GbE2c communicates with the Onboard Administrator through its internal management port
(port 19).
The factory default settings permit management and control access to the switch through the
10/100 Mbps Ethernet port on the Onboard Administrator, or the built-in console port. You also can
use the uplink Ethernet ports to manage and control the GbE2c.
The GbE2c management network has the following characteristics:
Port 19–Management port 19 has a fixed configuration, as follows:
100 Mbps
Full duplex
Flow control: both
No auto-negotiation
Untagged
Port VLAN ID (PVID): 4095
VLAN 4095—Management VLAN 4095 isolates management traffic within the GbE2c.
VLAN 4095 contains only one member port (port 19). No other ports can be members of
VLAN 4095.
Interface 256—Management interface 256 is associated with VLAN 4095. No other interfaces
can be associated with VLAN 4095. You can configure the IP address of the management
interface manually or through Dynamic Host Control Protocol (DHCP).
Gateway 4—This gateway is the default gateway for the management interface.
STG 128—If the GbE2c is configured to use multiple spanning trees, spanning tree group 128
(STG 128) contains management VLAN 4095, and no other VLANS are allowed in STG 128.
The default status of STG 128 is off.
If the GbE2c is configured to use Rapid Spanning Tree Protocol, STG 1 contains management
VLAN 4095.
To access the GbE2c management interface through the Onboard Administrator:
Use the Onboard Administrator internal DHCP server, through Enclosure-Based IP Addressing
Use an external DHCP server. Connect the Onboard administrator and the GbE2c to the
network, and disable Enclosure-Based IP Addressing.
Assign a static IP interface to the Onboard Administrator and to the GbE2c management
interface (interface 256).
