FTOS Configuration Guide for the C-Series - Force10 Networks

To configure a Management interface, use the following command in the CONFIGURATION mode:
Command Syntax Command Mode Purpose
interface ManagementEthernet interface CONFIGURATION Enter the slot (0-1) and the port (0).
In a system with 2 RPMs, therefore, 2
Management interfaces, the slot number
differentiates between the two
Management interfaces.
To view the Primary RPM Management port, use the show interface ManagementEthernet command in
the EXEC privilege mode. If there are 2 RPMs in the system, you cannot view information on that
interface.
To configure IP address on a Management interface, use the following command in the MANAGEMENT
INTERFACE mode:
Command Syntax Command Mode Purpose
ip address ip-address mask INTERFACE Configure an IP address and mask on the
interface.
• ip-address mask: enter an address in
dotted-decimal format (A.B.C.D) and
mask must be in /prefix format (/x)
If you have two RPMs in your system, each Management interface must be configured with a different IP
address. Unless the management route command is configured, you can only access the Management
interface from the local LAN. To access the Management interface from another LAN, you must configure
the management route command to point to the Management interface.
Alternatively, you can use virtual-ip to manage a system with one or two RPMs. A virtual IP is an IP
address assigned to the system (not to any management interfaces) and is a CONFIGURATION mode
command. When a virtual IP address is assigned to the system, the active management interface of the
RPM is recognized by the virtual IP address—not by the actual interface IP address assigned to it. During
an RPM failover, you do not have to remember the IP address of the new RPM’s management interface—
the system will still recognizes the virtual-IP address.
Important Things to Remember —virtual-ip
• virtual-ip is a CONFIGURATION mode command.
• When applied, the management port on the primary RPM assumes the virtual IP address. Executing
show interfaces and show ip interface brief commands on the primary RPM management interface
will display the virtual IP address and not the actual IP address assigned on that interface.
• A duplicate IP address message is printed for management port’s virtual IP address on an RPM
failover. This is a harmless error that is generated due to a brief transitory moment during failover
when both RPMs’ management ports own the virtual IP address, but have different MAC addresses.
• The primary management interface will use only the virtual IP address if it is configured. The system
can not be accessed through the native IP address of the primary RPM’s management interface.
