Configuring the MACsec confidentiality offset
The MACsec confidentiality offset specifies the number of bytes starting from the frame header. MACsec encrypts only the bytes after the offset in a frame.
MACsec uses the confidentiality offset propagated by the key server.

3. Set the MACsec confidentiality offset. | macsec confidentiality-offset offset-value | The default setting is 0, and the entire frame needs to be encrypted. The offset value can be 0, 30, or 50. |
