prvtStHelloTime

Module: PRVT-SPANNING-TREE-MIB

OID (symbolic): PRVT-SPANNING-TREE-MIB::prvtStHelloTime

OID (numeric): 1.3.6.1.4.1.738.1.5.107.1.1.3

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: The amount of time, in seconds, between the transmission of Configuration bridge PDUs by this node on any port when it is the root of the spanning tree or trying to become so. Note that the following relationship is enforced: prvtStMaxAge >= 2 x (prvtStHelloTime + 1)

What is prvtStHelloTime?

How often (1-40s) this bridge transmits Configuration BPDUs on a port while it is (or is trying to become) the STP root; constrained by prvtStMaxAge >= 2*(prvtStHelloTime+1), so raising it too high can force prvtStMaxAge upward too.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.738.1.5.107.1.1.3
snmpwalk -v2c -c public <target> PRVT-SPANNING-TREE-MIB::prvtStHelloTime

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.738.1.5.107.1.1.3.1
snmpget -v2c -c public <target> PRVT-SPANNING-TREE-MIB::prvtStHelloTime.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.738.1.5.107.1.1.3.1 i <value>
