Encryption of performance monitoring packets
NOTICE:
For description of parameters listed above and instruction on how to configure them, see the
TETRA BTS Service Software (TESS) User Guide.
Use the BTS Service Software tool for configuration of the Encrypted Ethernet site link,
especially during upgrade or migration procedures.
The algorithms used for encryption are:
AES 128
AES 192
AES 256
The algorithms used for authentication are:
SHA-1
SHA-256
SHA-384
SHA-512
To verify if the link encryption option is enabled or disabled in the system, use the ipsec config
command. The command displays both, the Main system and the Local system site link encryption
configuration.
