What is nwAppnExtIfSsap?

This read-write octet string (1 byte) specifies the Source SAP address used by this port on token ring or ethernet media. Mismatched SAP values between this router and the adjacent node will prevent LLC2 sessions from establishing correctly, making this a common troubleshooting checkpoint. An admin diagnosing a failed LAN-attached APPN link would confirm this SAP value matches what the far-end device expects.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.2.1.2.1.29
snmpwalk -v2c -c public <target> CTRON-APPN-MIB::nwAppnExtIfSsap

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.2.1.2.1.29.1
snmpget -v2c -c public <target> CTRON-APPN-MIB::nwAppnExtIfSsap.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.2.2.2.3.5.2.2.2.1.2.1.29.1 s <value>
