Configuring Management Interfaces On The S-Series - Dell S4820T Configuration Manual

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 Management Interfaces on the S-Series

You can manage the S-Series from any port.
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
• 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.
