| Name | Data Type | Qualifiers |
| Name | Data Type | Value | Scope | Flavors |
| ApeInFrames | uint32 |
| Counter | boolean | true | None | None |
| Description | string | The number of All Paths Explorer frames, also referred to as All Routes Explorer frames, that have been received by the port from its segment. | None | TRANSLATABLE= true |
| Mappingstrings | string | MIB.IETF|RFC1525-MIB.dot1dSrPortApeInFrames | None | None |
| ApeOutFrames | uint32 |
| Counter | boolean | true | None | None |
| Description | string | The number of all Paths Explorer Frames, also referred to as All Routes Explorer frames, that have been transmitted by the port on its segment. | None | TRANSLATABLE= true |
| Mappingstrings | string | MIB.IETF|RFC1525-MIB.dot1dSrPortApeOutFrames | None | None |
| DupLanIdOrTreeErrors | uint32 |
| Counter | boolean | true | None | None |
| Description | string | The number of duplicate LAN IDs or Tree errors. This helps in detection of problems in networks containing older IBM Source Routing Bridges. | None | TRANSLATABLE= true |
| Mappingstrings | string | MIB.IETF|RFC1525- MIB.dot1dSrPortDupLanIdOrTreeErrors | None | None |
| DuplicateSegmentDiscards | uint32 |
| Counter | boolean | true | None | None |
| Description | string | The number of frames that have been discarded by the port because the routing descriptor field contained a duplicate segment identifier. | None | TRANSLATABLE= true |
| Mappingstrings | string | MIB.IETF|RFC1525- MIB.dot1dSrPortDuplicateSegmentDiscards | None | None |
| HopCountExceedsDiscards | uint32 |
| Counter | boolean | true | None | None |
| Description | string | The number of explorer frames that have been discarded by the port because the Routing Information Field has exceeded the maximum route descriptor length. | None | TRANSLATABLE= true |
| Mappingstrings | string | MIB.IETF|RFC1525- MIB.dot1dSrPortHopCountExceedsDiscards | None | None |
| LanIdMismatches | uint32 |
| Counter | boolean | true | None | None |
| Description | string | 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. | None | TRANSLATABLE= true |
| Mappingstrings | string | MIB.IETF|RFC1525- MIB.dot1dSrPortLanIdMismatches | None | None |
| SegmentMismatchDiscards | uint32 |
| Counter | boolean | true | None | None |
| Description | string | The number of explorer frames that have been discarded by the port because the routing descriptor field contained an invalid adjacent segment value. | None | TRANSLATABLE= true |
| Mappingstrings | string | MIB.IETF|RFC1525- MIB.dot1dSrPortSegmentMismatchDiscards | None | None |
| SpecInFrames | uint32 |
| Counter | boolean | true | None | None |
| Description | string | The number of Specifically Routed frames, also referred to as Source Routed Frames, that have been received from the segment attached to the port. | None | TRANSLATABLE= true |
| Mappingstrings | string | MIB.IETF|RFC1525-MIB.dot1dSrPortSpecInFrames | None | None |
| SpecOutFrames | uint32 |
| Counter | boolean | true | None | None |
| Description | string | The number of Specifically Routed frames, also referred to as Source Routed Frames, that the port has transmitted on its segment. | None | TRANSLATABLE= true |
| Mappingstrings | string | MIB.IETF|RFC1525-MIB.dot1dSrPortSpecOutFrames | None | None |
| SteInFrames | uint32 |
| Counter | boolean | true | None | None |
| Description | string | The number of spanning tree explorer frames that have been received by the port from its segment. | None | TRANSLATABLE= true |
| Mappingstrings | string | MIB.IETF|RFC1525-MIB.dot1dSrPortSteInFrames | None | None |
| SteOutFrames | uint32 |
| Counter | boolean | true | None | None |
| Description | string | The number of spanning tree explorer frames that have been transmitted by the port on its segment. | None | TRANSLATABLE= true |
| Mappingstrings | string | MIB.IETF|RFC1525-MIB.dot1dSrPortSteOutFrames | None | None |
