To configure IP addresses on a Management interface, use the following command in the
MANAGEMENT INTERFACE mode:
If there are 2 RPMs on the 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, the
management
route
command must be configured 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.
• Once the virtual IP address is removed, the system is accessible through the native IP address of the
primary RPM’s management interface.
• Primary and secondary management interface IP and virtual IP must be in the same subnet.
Configure Management Interfaces on the S-Series
You can manage the S-Series from any port. Configure an IP address for the port using the ip address
command, and enable it using the command
no shutdown. The user may use the command description
from INTERFACE mode to note that the interface is the management interface. There is no separate
management routing table, so the user must configure all routes in the IP routing table (the
ip route
command).

• ip-address mask: enter an address in
dotted-decimal format (A.B.C.D), the
