Description:
dot1dStpBridgeHelloTime: From RFC1493(Bridge MIB). The value that all bridges use for HelloTime when this bridge is acting as the root. The granularity of this timer is specified by 802.1D- 1990 to be 1 second. An agent may return a badValue error if a set is attempted to a value which is not a whole number of seconds. Valid value between 1 and 10. Default is 2 seconds. Value 0 is returned if no STP is not configured for this vlan.
What is snVLanByPortCfgStpGroupHelloTime?
This configures how often the spanning tree root bridge sends BPDU hello packets within a VLAN, in seconds (1-10, default 2). Shorter intervals detect failures faster but consume more bandwidth. A network operator would lower this on edge ports prone to flapping but keep it high on stable core links.
