nwAppnSysCosSize

Module: CTRON-APPN-MIB

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

OID (numeric): 1.3.6.1.4.1.52.4.2.2.2.3.5.2.1.1.2.12

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Specifies maximum number of COS definitions maintained in the COS database weights cache. It determines the size of the COS Database weights cache. Note: if nwAppnSysCosSize 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 nwAppnSysCosSize will reflect this new value.

What is nwAppnSysCosSize?

This read-write integer (1-65535) caps how many Class of Service definitions are kept in the COS database weights cache, though the router may internally raise too-small values once enabled. This cache size affects how quickly the node can compute COS-based routes without recalculating weights from scratch each time. An admin supporting many distinct COS profiles would increase this value and then re-read the OID to confirm the accepted size.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.1.1.2.12
snmpwalk -v2c -c public <target> CTRON-APPN-MIB::nwAppnSysCosSize

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.1.1.2.12.1
snmpget -v2c -c public <target> CTRON-APPN-MIB::nwAppnSysCosSize.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.1.1.2.12.1 i <value>
