Enumeration
The layer 2 mode. This value has influence on the HDLC address field (first byte of a HDCL frame). When configured as DTE(1) the address in a command frame is 0x01, when configured as DCE(2) it is 0x03. For response frames it is vice versa. When configured as AUTO(3), layer 2 is set to the same mode like L1Mode is set.

| x21IfIndex mandatory Unique index of the X21 interface. | column | Integer32 | .1.3.6.1.4.1.272.4.10.1.1.1 |
| x21IfTxPackets mandatory Count of transmitted valid Frames. | column | RFC1155-SMICounter | .1.3.6.1.4.1.272.4.10.1.1.10 |
| x21IfTxOctets mandatory Count of transmitted bytes. | column | RFC1155-SMICounter | .1.3.6.1.4.1.272.4.10.1.1.11 |
| x21IfRxResets mandatory Count of receiver resets. Under rare circumstances it
might be necessary to reset the receiver to work
properly. | column | RFC1155-SMICounter | .1.3.6.1.4.1.272.4.10.1.1.12 |
| x21IfRxAborts mandatory Count of receiver aborts. The sender of a frame can
indicate a frame as aborted with a special Abort
sequence. | column | RFC1155-SMICounter | .1.3.6.1.4.1.272.4.10.1.1.13 |
| x21IfRxOverruns mandatory Count of receiver overruns. If the X21 card is unable
to grant sufficiently soon/often the bus, the
32-character RxFIFO may fill up. This leads to loss of
data. | column | RFC1155-SMICounter | .1.3.6.1.4.1.272.4.10.1.1.14 |
| x21IfRxCRCErrors mandatory Count of corrupted frames. Errors due to interference
on the X21 cable. | column | RFC1155-SMICounter | .1.3.6.1.4.1.272.4.10.1.1.15 |
| x21IfRxGiantFrames mandatory Count of received frames with illegal framesize. This
can occur if a frame delimiter is destroyed. | column | RFC1155-SMICounter | .1.3.6.1.4.1.272.4.10.1.1.16 |
| x21IfTxResets mandatory Count of transmitter resets. Under rare circumstances
it might be necessary to reset the transmitter to work
properly. | column | RFC1155-SMICounter | .1.3.6.1.4.1.272.4.10.1.1.17 |
| x21IfTxAborts mandatory Count of transmitter aborts. While sending a frame it
might be necessary to indicate this frame as aborted. In
this case the receiver regards this frame as illegal. | column | RFC1155-SMICounter | .1.3.6.1.4.1.272.4.10.1.1.18 |
| x21IfTxUnderruns mandatory Count of transmitter underruns. The serial data for the
X21 card is supplied too slowly. | column | RFC1155-SMICounter | .1.3.6.1.4.1.272.4.10.1.1.19 |
| x21IfL1State mandatory The X21 physical layer state
dn(1) physical layer is inactive;
up(2) physical layer is active; | column | Enumeration | .1.3.6.1.4.1.272.4.10.1.1.2 |
| x21IfTxGiantFrames mandatory Count of transmitted frames with illegal
framesize. This can occur if an upper module creates
packets with more than the maximum allowed packet size. | column | RFC1155-SMICounter | .1.3.6.1.4.1.272.4.10.1.1.20 |
| x21IfIfReSyncs mandatory Count of interface resynchronization. Under rare
circumstances it might be necessary to resynchronize
the physical interface to work properly. | column | RFC1155-SMICounter | .1.3.6.1.4.1.272.4.10.1.1.21 |

to one interface. | column | Integer32 | .1.3.6.1.4.1.272.4.10.1.1.22 |

DCE(2) the X21 interface provides the clock. | column | Enumeration | .1.3.6.1.4.1.272.4.10.1.1.3 |
| x21IfIfLeads mandatory The value of IfLeads has influence on the state of the
physical layer (L1State). When configured as
IfLeads=enabled(1), the state of the physical layer
depends on the signals of t… | column | Enumeration | .1.3.6.1.4.1.272.4.10.1.1.4 |
| x21IfSpeed mandatory The X21 interface speed in bits per second. The range
can be configured between 2Mbits and 2400 Bits per
second. | column | Enumeration | .1.3.6.1.4.1.272.4.10.1.1.5 |
