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

Example of the show interface and show ip route Commands
To display the configuration for a given port, use the show interface command in EXEC Privilege mode, as
shown in the following example. To display the routing table, use the
show ip route command in EXEC
Privilege mode.
Dell#show int TenGigabitEthernet 1/1
