Description
This is an identification string between 1 and 79 characters (alpha and/or numeric) by which the
Mobile IP destination context will be recognized by the system.
NOTE: For this configuration, the destination context name should not match the domain name of a
specific domain. It should, however, match the name of the context in which the HA service is
configured if a separate system is used to provide HA functionality.
This is an identification string between 1 and 79 characters (alpha and/or numeric) by which the
interface will be recognized by the system.
Multiple names are needed if multiple interfaces will be configured.
Gi interfaces are configured in the destination context.
These will be assigned to the Gi interface.
Multiple addresses and/or subnets are needed if multiple interfaces will be configured.
This specifies the physical port to which the interface will be bound. Ports are identified by the
chassis slot number where the line card resides in, followed by the number of the physical connector
on the line card. For example, port 17/1 identifies connector number 1 on the card in slot 17.
A single physical port can facilitate multiple interfaces.
This is an identification string between 1 and 79 characters (alpha and/or numeric) by which the
physical port will be recognized by the system.
Multiple descriptions will be needed if multiple ports will be used.
Physical ports are configured within the destination context and are used to bind logical Gi
interfaces.
Used when configuring static routes from the Gi interface(s) to a specific network.
This is an identification string between 1 and 63 characters (alpha and/or numeric) by which the FA
service will be recognized by the system
.Multiple names are needed if multiple FA services will be used.
FA services are configured in the destination context.
Specifies the port used by the FA service and the HA for communications. The UDP port number
can be any integer value between 1 and 65535. The default value is 434.
HA IP address: Specifies the IP address of the HAs with which the FA service communicates. The
FA service allows the creation of a security profile that can be associated with a particular HA.
Index: Specifies the shared SPI between the FA service and a particular HA. The SPI can be
configured to any integer value between 256 and 4294967295.Multiple SPIs can be configured if the
FA service is to communicate with multiple HAs.
Secrets: Specifies the shared SPI secret between the FA service and the HA. The secret can be
between 1 and 127 characters (alpha and/or numeric).An SPI secret is required for each SPI
configured.
