PTP with Media Access Control Security (MACsec) Encryption

PTP works well with Media Access Control Security (MACsec) encryption enabled on the same port at the same time on supported routers.

PTP works well with Media Access Control Security (MACsec) encryption enabled on the same port at the same time on supported routers. However, the following limitations apply:

  • The maximum limit for MACsec-enabled logical interfaces (IFL) is 200 per system.

  • The maximum limit for MACsec-enabled ports with physical interfaces (IFDs) and IFLs where MACsec and PTP are enabled together on different ports is 200 per system.

  • The maximum number of IFLs that can be supported on both 1G and 10G ports is 128.

  • PTP in clear text mode is not supported.
