What is nwAppnSysMaxIsrSessions?

This read-write integer (1-65535) sets the maximum number of intermediate routing sessions APPN Routing Services will allow to pass through this node at one time. It is the primary capacity control for how much transit SNA session traffic this router will carry as an intermediate node. An admin who wants this router to prioritize its own local sessions over transit traffic would lower this limit.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.1.1.2.18
snmpwalk -v2c -c public <target> CTRON-APPN-MIB::nwAppnSysMaxIsrSessions

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.1.1.2.18.1
snmpget -v2c -c public <target> CTRON-APPN-MIB::nwAppnSysMaxIsrSessions.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.1.1.2.18.1 i <value>
