If there are two RPMs on the system, configure each Management interface with a different IP address. Unless
you configure the management route command, you can only access the Management interface from the
local LAN. To access the Management interface from another LAN, configure the management route
command to point to the Management interface.
Alternatively, you can use the virtual-ip command 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
still recognizes the virtual-IP address.
• virtual-ip is a CONFIGURATION mode command.
• When applied, the management port on the primary RPM assumes the virtual IP address. Executing the
show interfaces and show ip interface brief commands on the primary RPM management
interface displays the virtual IP address and not the actual IP address assigned on that interface.
• A duplicate IP address message is printed for the management port’s virtual IP address on an RPM
failover. This behavior 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 uses only the virtual IP address if it is configured. The system cannot
be accessed through the native IP address of the primary RPM’s management interface.
• After 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.
To view the Primary RPM Management port, use the show interface Managementethernet command in
EXEC Privilege mode. If there are two RPMs, you cannot view information on that interface.
Configuring a Management Interface on an
Ethernet Port
You can manage the system through any port using remote access such as Telnet.
To configure an IP address for the port, use the following commands. There is no separate management
routing table, so configure all routes in the IP routing table (the ip route command).
• Configure an IP address.
INTERFACE mode
ip address ip-address mask
• Enable the interface.
INTERFACE mode
no shutdown
• The interface is the management interface.
INTEFACE mode
