nnMstMaxHopCount

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

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

OID (numeric): 1.3.6.1.4.1.45.5.5.1.1.2

Node type: OBJECT-TYPE

Type: Integer32

Access: read-write

Description: Indicates the Maximum Hop Count value. 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 nnMstMaxHopCount?

Sets the maximum number of bridge hops an MSTP BPDU can travel within the region before being discarded, bounding how large the region's active topology can be. Defaults to 2000 (20 hops in real units, since values are 1/100 hop granularity here expressed directly as an integer).

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.45.5.5.1.1.2
snmpwalk -v2c -c public <target> NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstMaxHopCount

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.45.5.5.1.1.2.1
snmpget -v2c -c public <target> NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstMaxHopCount.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.45.5.5.1.1.2.1 i <value>
