swMSTPStpForwardDelay

Module: MSTP-MIB

OID (symbolic): MSTP-MIB::swMSTPStpForwardDelay

OID (numeric): 1.3.6.1.4.1.171.12.15.1.5

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This value, controls how long a port changes its spanning state from blocking to learning state and from learning to forwarding state. Note that the range for this parameter is related to MaxAge

What is swMSTPStpForwardDelay?

This read-write value (400-3000, in hundredths of a second) controls how long a port stays in the listening/learning states before moving to forwarding, and is constrained relative to swMSTPStpMaxAge. Admins shorten this cautiously to speed up convergence after a topology change, but too short a value risks temporary loops.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.15.1.5
snmpwalk -v2c -c public <target> MSTP-MIB::swMSTPStpForwardDelay

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.15.1.5.1
snmpget -v2c -c public <target> MSTP-MIB::swMSTPStpForwardDelay.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.171.12.15.1.5.1 i <value>
