IP Services Gateway
Engineering Rules
This appendix
lists IPSG-specific engineering rules that must be considered prior
to configuring the system for your network deployment. General and
network-specific rules are available in the appendix of the System Administration
Guide for the specific network type.
The following rules
are covered in this appendix:
IPSG Context and
Service Rules
- Only one IPSG service
can be configured within a context.
- Single context configurations
must have the ingress port identified using the ingress-mode command
in the Ethernet Port Configuration Mode.
- In single context configurations,
if data packets are received before a session is initiated, the
packets could be routed to their destination without being processed.
Use separate ingress and egress contexts to prevent this issue.
IPSG RADIUS Messaging
Rules
- The sending of RADIUS
accounting start messages to the RADIUS server is delayed by the
IPSG until a session is successfully started.
