Hello Time: (1 - 10 sec)

The Hello Time can be set from 1 to 10 seconds. This is the interval between two

transmissions of BPDU packets sent by the Root Bridge to tell all other switches

that it is indeed the Root Bridge. This field will only appear here when STP or

RSTP is selected for the STP Version. For MSTP, the Hello Time must be set on

a port per port basis. See the MSTP Port Information section for further details.

Max Age: (6 - 40 sec)

The Max Age may be set to ensure that old information does not endlessly

circulate through redundant paths in the network, preventing the effective

propagation of the new information. Set by the Root Bridge, this value will aid in

determining that the Switch has spanning tree configuration values consistent with

other devices on the bridged LAN. If the value ages out and a BPDU has still not

been received from the Root Bridge, the Switch will start sending its own BPDU to

all other switches for permission to become the Root Bridge. If it turns out that

your switch has the lowest Bridge Identifier, it will become the Root Bridge. The

user may choose a time between 6 and 40 seconds. The default value is 20.
