Changes the wait time before RSTP refreshes protocol configuration information. hello-time Set the time interval between generation of RSTP bridge protocol data units (BPDUs). Syntax hello-time [milli-second] seconds To return to the default value, use the no hello-time command. Parameters seconds milli-second Enter a number as the time interval between transmission of BPDUs. Range: 1 to 10 seconds Default: 2 seconds.

Range: 50 - 950 milliseconds Defaults 2 seconds Command Modes CONFIGURATION RSTP (conf-rstp) Command History Version 8.3.16.1 Introduced on MXL 10/40GbE Switch IO Module Usage Information The hello time is encoded in BPDUs in increments of 1/256ths of a second. The standard minimum hello time in seconds is 1 second, which is encoded as 256. Millisecond hello times are encoded using values less than 256; the millisecond hello time equals (x/1000)*256. When millisecond hellos are configured, the default hello interval of 2 seconds is still used for edge ports; the millisecond hello interval is not used. Related Commands forward-delay max-age Changes the wait time before RSTP transitions to the Forwarding state.
