Description: Number of instances that SIP3 BE tag is not macthed.
What is lportSmdsCntSip3BetagMismatchs?
This counts instances where the Beginning-End, BE, tag in a SIP3 PDU's header did not match the corresponding tag in its trailer, a fundamental integrity check that SMDS uses to confirm a multi-segment PDU's header and trailer belong to the same original message. An admin treats mismatches here seriously since a BE tag mismatch usually points to segment reassembly corruption somewhere in the SMDS transport path rather than a simple CPE misconfiguration. For example, a rising lportSmdsCntSip3BetagMismatchs count combined with lportSmdsCntSip3BasizeMismatchs increasing together strongly suggests PDUs are being corrupted or misordered during reassembly, not just a header field typo.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.118 snmpwalk -v2c -c public <target> CASCADE-MIB::lportSmdsCntSip3BetagMismatchs
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.118.1 snmpget -v2c -c public <target> CASCADE-MIB::lportSmdsCntSip3BetagMismatchs.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.5.1.1.118.1 i <value>
