Default Values For Internal Application Ports For Critical And Best-Effort Traffic - TTE Tech A664 Lab v2.0 User Manual

6. CREATING A SWITCH CONFIGURATION
6.3 Configuring the internal end system
The management CPU of the switch uses an internal end system to send and receive frames for data
loading via ARINC 615A, ICMP (ping) and diagnostics via SNMP.
Data loading, ICMP and SNMP via best-effort (Ethernet) traffic are always possible by selecting the
NOTE
default configuration via pin programming.
Rate-constrained management configuration
If a management service such as data loading via ARINC 615A, ICMP, and SNMP shall be available via
rate-constrained (i.e., critical) traffic, the corresponding virtual links between the maintenance computer,
the switch and the switch-internal end system need to be defined and configured correctly. The minimum
VL configuration from a port to the internal end system is 4 user-defined VLs.
For data loading via ARINC 615A, ICMP, SNMP, and other management functionalities via critical traffic,
the application ports must be configured. See Table
application ports.

The application port configuration file utilizes the .ini file format. Each section in the file represents exactly
one configuration for one application port. The example below shows a valid section in the application
port configuration file:
[#ICMP_RX]
dir = rx
port = 8
part = 1
The values for port and part must match the values of the header file of the internal end system, which
is created by the TTE-Tools (see Section
must be declared in the example_configs.ini file.
The example_configs.ini file defines configurations grouped in sections, with each section representing
exactly one configuration. The order of sections listed in the .ini file implicitly shows the relation between
a configuration position selected by pin programming (see Table
the .ini file. This means that the binary files defined in the first section correspond to position 1, while
1. The port type is MACRAW in the case of best-effort traffic.
2. In the case of best-effort traffic, port and partition cannot be changed and are set to 0.
