382 | Interfacesw w w . d e l l . c o m | s u p p o r t . d e l l . c o m To configure IP addresses on a Management interface, use the following command in theMANAGEMENT INTERFACE mode:If there are 2 RPMs on the system, each Management interface must be configured with a different IPaddress. Unless the management route command is configured, you can only access the Managementinterface from the local LAN. To access the Management interface from another LAN, the managementroute command must be configured to point to the Management interface.Alternatively, you can use virtual-ip to manage a system with one or two RPMs. A virtual IP is an IPaddress assigned to the system (not to any management interfaces) and is a CONFIGURATION modecommand. When a virtual IP address is assigned to the system, the active management interface of theRPM is recognized by the virtual IP address—not by the actual interface IP address assigned to it. Duringan RPM failover, you do not have to remember the IP address of the new RPM’s management interface—the system will still recognizes the virtual-IP address.Important Things to Remember — virtual-ip• virtual-ip is a CONFIGURATION mode command.• When applied, the management port on the primary RPM assumes the virtual IP address. Executingshow interfaces and show ip interface brief commands on the primary RPM management interfacewill display the virtual IP address and not the actual IP address assigned on that interface.• A duplicate IP address message is printed for management port’s virtual IP address on an RPMfailover. This is a harmless error that is generated due to a brief transitory moment during failoverwhen both RPMs’ management ports own the virtual IP address, but have different MAC addresses.• The primary management interface will use only the virtual IP address if it is configured. The systemcan not be accessed through the native IP address of the primary RPM’s management interface.• Once the virtual IP address is removed, the system is accessible through the native IP address of theprimary RPM’s management interface.• Primary and secondary management interface IP and virtual IP must be in the same subnet.Configure Management Interfaces on the S-SeriesYou can manage the S-Series from any port. Configure an IP address for the port using the ip addresscommand, and enable it using the command no shutdown. The user may use the command descriptionfrom INTERFACE mode to note that the interface is the management interface. There is no separatemanagement routing table, so the user must configure all routes in the IP routing table (the ip routecommand).Command Syntax Command Mode Purposeip address ip-address mask INTERFACE Configure an IP address and mask on theinterface.• ip-address mask: enter an address indotted-decimal format (A.B.C.D), themask must be in /prefix format (/x)
