R3303-HP HSR6800 Routers Interface Command Reference

80
Default command level
2: System level
Parameters
seconds: Specifies the interval at which an interface sends keepalive packets. The value range is 0 to
32767 seconds.
retries: Specifies the maximum number of keepalive attempts. The value range is 1 to 255. If the interface
does not receive a response when this limit is reached, the interface considers the remote end to be
down.
Examples
# Set the keepalive interval to 20 seconds and the maximum number of keepalive attempts to 10 on
Serial 1/0/0.

virtualbaudrate
Use virtualbaudrate to set a virtual baud rate for the DTE-side interface.
Use undo virtualbaudrate to remove the specified virtual baud rate.

Parameters
virtualbaudrate: Baud rate (in bps) to be set, which must be consistent with the one configured at the DCE
side. It can be 1,200, 2,400, 4,800, 9,600, 19,200, 38,400, 56,000, 57,600, 64,000, 72,000,
115,200, 128,000, 192,000, 256,000, 384,000, 512,000, 768,000, 1024,000, 2,048,000, or
4,096,000.
Usage guidelines
When working as DTE, the serial interface determines its baud rate through negotiation with the DCE
side. The virtualbaudrate command, however, allows you to configure DTE-side baudrate manually, but
the configured value must be the same as the one set at the DCE side.
Configure the baudrate command at DCE side and the virtualbaudrate command at DTE side (only
when the interface is operating in synchronous mode). Avoid configuring the two commands at the same
end of a link.
At DCE side, the display interface command displays the baud rate of the interface; whereas at the DTE
end, the command displays the virtual baud rate of the interface.
