How to adjust the serial interface rate of an AR routers

The serial interface rate of an AR router cannot be adjusted.

For a serial interface running in DTE mode, you can run the virtualbaudrate command to configure the virtual baud rate of the serial interface in synchronous mode.
For a serial interface running in DCE mode, you can run the baudrate command to configure the baud rate of the serial interface in synchronous mode.

The baud rate determines the transmission rate of a line. Supported baud rate range varies with cable types.
? V.24DCE: 1200 bit/s - 64000 bit/s
Baud rate ranges supported by V.35DCE, RS449DCE, and RS530DCE are described as follows:
- The baud rate supported by 1SA/2SA interface cards ranges from 1200 bit/s to 2048000 bit/s.
- The baud rate supported by 8SA interface cards ranges from 1200 bit/s to 8192000 bit/s.
- The baud rate supported by the serial interface of AR2202-48FE ranges from 1200 bit/s to 8192000 bit/s.

Supported virtual baud rate range varies with cable types.
? V.24DTE: 1200 bit/s - 64000 bit/s
Virtual baud rate ranges supported by V.35DTE, X.21DTE, RS449DTE, and RS530DTE are described as follows:
- Virtual baud rate supported by 1SA/2SA interface cards ranges from 1200 bit/s to 2048000 bit/s.
- Virtual baud rate supported by 8SA interface cards ranges from 1200 bit/s to 8192000 bit/s.
- Virtual baud rate supported by the serial interface of AR2202-48FE ranges from 1200 bit/s to 8192000 bit/s.

Ensure that the baud rate configured on the DCE device (by running the baudrate command) is in accordance with the virtual baud rate configured on the DTE device (by running the virtualbaudrate command). Otherwise, packets may be discarded.
