nnMstCistBridgeForwardDelay

Module: NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB

OID (symbolic): NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstCistBridgeForwardDelay

OID (numeric): 1.3.6.1.4.1.45.5.5.1.1.11

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 specifies that the range for this parameter is related to the value of BridgeMaxAge. The granularity of this timer is specified 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 nnMstCistBridgeForwardDelay?

Sets the ForwardDelay value this bridge advertises to the rest of the network when acting as the CIST root, in whole seconds; its valid range is tied to the configured MaxAge value. Defaults to 1500.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.45.5.5.1.1.11
snmpwalk -v2c -c public <target> NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstCistBridgeForwardDelay

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.45.5.5.1.1.11.1
snmpget -v2c -c public <target> NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstCistBridgeForwardDelay.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.45.5.5.1.1.11.1 s <value>
