Endpoint Protection for Linux is unable to communicate with Manager when NIC bonding is configured.

Endpoint Protection


When using NIC bonding or teaming in Linux, Symantec Endpoint Protection (SEP) for Linux is unable to register and communicate properly with a SEP Manager (SEPM).

Sylink debug log:

[ERROR] Send of message returned error 400 Bad Request


SEPM secars log:

4 Bad Request, MacAddress is invalid!


In order for a SEP client to register with the SEPM, it needs to identify the MAC address associated with the network interface being used. When NIC bonding is enabled, the SEPFL client is unable to determine the MAC address, thus registration fails.




This issue has been resolved in SEP 14.2 RU1 MP1.

As a workaround, either disable NIC bonding or leave the SEP for Linux client as unmanaged.
