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.
