lportSmdsCntSip3BasizeMismatchs
Module: CASCADE-MIB
OID (symbolic): CASCADE-MIB::lportSmdsCntSip3BasizeMismatchs
OID (numeric): 1.3.6.1.4.1.277.1.5.1.1.125
Node type: OBJECT-TYPE
Type: Counter
Access: read-write
Description: Number of instances that SIP3 BA sizes in the header and trailer are not matched.
What is lportSmdsCntSip3BasizeMismatchs?
This counts instances where the BAsize value recorded in a SIP3 PDU's header disagrees with the BAsize value recorded in its trailer, a specific header-versus-trailer consistency check distinct from lportSmdsCntSip3BasizeIncorrects, header versus actual payload, and lportSmdsCntSip3BasizeInvalids, out-of-range value. An admin treats header/trailer mismatches as a strong indicator of in-transit corruption or reassembly problems, since a PDU's header and trailer originate together and should always agree if the PDU traveled intact. For example, seeing this counter climb together with lportSmdsCntSip3BetagMismatchs strengthens the case that PDUs are being corrupted or improperly reassembled somewhere in the switching fabric rather than being malformed at the source.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.125 snmpwalk -v2c -c public <target> CASCADE-MIB::lportSmdsCntSip3BasizeMismatchs
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.125.1 snmpget -v2c -c public <target> CASCADE-MIB::lportSmdsCntSip3BasizeMismatchs.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.5.1.1.125.1 i <value>
