Teklogix 7035, 8255 & 8260 Terminals User Manual
Simultan. Binds
When this parameter is set to ‘Y’, it enables multiple (simultaneous) bindings. This
means that the terminal can roam back to a Foreign Agent without registering again
(assuming the old registration has not expired).
Max Num Binds
The value assigned to ‘Max Num Binds’ represents the maximum number of
bindings that the terminal will recognize at one time. When determining the value
for this parameter, make certain that the maximum number of base stations that can
be simultaneously accessed in the mobile node's (terminal’s) range are represented.
Foreign Agents
The number assigned to this parameter represents the maximum number of Foreign
Agents that can be stored locally at one time. While normally, the value assigned
here should be fairly low (the default value is 10), it is critical that you set the value
high enough so that the terminal always has access to a Foreign Agent and never
loses contact with the host.
Home Agent SPI
This parameter represents the Home Agent Security Parameter Index (SPI) assigned
to the terminal’s Home Agent. In order for a terminal to communicate with a
particular Home Agent, the value assigned here must match the SPI of the Home
Agent. The default value is 333.
Note: The minimum acceptable value is 256.
Home Agent Key
The “Home Agent Key” is a 16 byte text string that acts as a password. In order for
the terminal to communicate with the Home Agent, the terminal key must match the
key assigned to the Home Agent.
Replay Protectn
Setting this parameter to ‘Y’ enables time-stamp based replay protection. This
prevents outside packets from infiltrating your system. The value assigned to the
terminal must match the value set at the Home Agent.
