nwAppnSysTreeSize

Module: CTRON-APPN-MIB

OID (symbolic): CTRON-APPN-MIB::nwAppnSysTreeSize

OID (numeric): 1.3.6.1.4.1.52.4.2.2.2.3.5.2.1.1.2.13

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Specifies the number of routes maintained in the Topology Database routing tree cache. Note: if nwAppnSysTreeSize is set to a value too small, it will be internally increased to a higher value after APPN Routing Services has been successfully enabled. A subsequent GET operation on nwAppnSysTreeSize will reflect this new value.

What is nwAppnSysTreeSize?

This read-write integer (1-65535) sets how many routes are held in the Topology Database's routing tree cache, with too-small values possibly raised internally after enabling. A bigger tree cache speeds up route computation for a network with many alternate paths, at the cost of more memory. An admin managing a densely meshed APPN backbone would raise this value to reduce repeated tree recomputation.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.1.1.2.13
snmpwalk -v2c -c public <target> CTRON-APPN-MIB::nwAppnSysTreeSize

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.1.1.2.13.1
snmpget -v2c -c public <target> CTRON-APPN-MIB::nwAppnSysTreeSize.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.1.1.2.13.1 i <value>
