What is lportSmdsCntSip3SaTypeInvalids?

This counts instances of an invalid source address type field in received SIP3 PDUs, the source-address mirror of lportSmdsCntSip3DaTypeInvalids. An admin uses it the same diagnostic way, flagging a sender whose SMDS stack is misconstructing the type-indicator portion of its own source address field. For example, a persistent count here for traffic from one particular port suggests that port's connected device is misconfiguring how it stamps its own address type on outgoing PDUs.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.123
snmpwalk -v2c -c public <target> CASCADE-MIB::lportSmdsCntSip3SaTypeInvalids

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.123.1
snmpget -v2c -c public <target> CASCADE-MIB::lportSmdsCntSip3SaTypeInvalids.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.5.1.1.123.1 i <value>
