Re: physical-layer sync command not supported

Hi,

As I know the 2509 has 2 serial and 8 async interface. The physical-layer sync command is used on async/sync interfaces to select the sync mode. As you have only sync or async (no dual mode) interface the command is not applicable.

Hope it helps,

Krisztian
