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
