Module: SOURCE-ROUTING-MIB

OID (symbolic): SOURCE-ROUTING-MIB::dot1dSrPortLanIdMismatches

OID (numeric): 1.3.6.1.2.1.17.3.1.1.18

Description: The number of ARE and STE frames that were discarded because the last LAN ID in the routing information field did not equal the LAN-in ID. This error can occur in implementations which do only a LAN-in ID and Bridge Number check instead of a LAN-in ID, Bridge Number, and LAN-out ID check before they forward broadcast frames.

What is dot1dSrPortLanIdMismatches?

Counts ARE and STE frames discarded because the last LAN ID in the routing information field didn't match the LAN-in ID, an error seen in bridges that skip a full LAN-out ID check before forwarding.
