mSTBridgeForwardDelay

Module: PRVT-MST-MIB

OID (symbolic): PRVT-MST-MIB::mSTBridgeForwardDelay

OID (numeric): 1.3.6.1.4.1.738.1.5.107.1.3.8

Node type: OBJECT-TYPE

Type: Timeout

Access: read-write

Description: The value that all bridges use for ForwardDelay when this bridge is acting as the root. Note that 802.1D-1990 specifies that the range for this parameter is related to the value of mSTBridgeMaxAge. 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 operation is attempted with a value that is not a whole number of seconds.

What is mSTBridgeForwardDelay?

This read-write Timeout (400-3000, in hundredths of a second) sets the ForwardDelay value all bridges would use if this bridge became the root; sets must be a whole number of seconds or the agent returns badValue.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.738.1.5.107.1.3.8
snmpwalk -v2c -c public <target> PRVT-MST-MIB::mSTBridgeForwardDelay

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.738.1.5.107.1.3.8.1
snmpget -v2c -c public <target> PRVT-MST-MIB::mSTBridgeForwardDelay.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.738.1.5.107.1.3.8.1 s <value>
