bridgeDomainBridgeHelloTime
Module: ACMIB
OID (symbolic): ACMIB::bridgeDomainBridgeHelloTime
OID (numeric): 1.3.6.1.4.1.1751.2.18.5.9.1.14
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: 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.
What is bridgeDomainBridgeHelloTime?
This OID sets the hello timer (1–10 seconds) that the bridge uses for its spanning tree hello transmissions when serving as the network root. Engineers tune this on the designated root to accelerate failure detection; smaller values enable quicker convergence when links fail. For example, reducing this from 2 to 1 second doubles the frequency of status updates and halves detection time.
