# AHDLC Dropped Packets

The AHDLC Dropped Packets dialog box allows you to view information about the dropped packets.

## Procedure

1. Right-click the device, then select Configure, or double-click the device.

2. Select AHDLC Engine Details from the Category list.

3. Select an AHDLC engine and click Dropped Packets.

The following information appears:

Decoding Drop (cCdmaAhdlcDropPktsDec)

Encoding Drop (cCdmaAhdlcDropPktsEnc)

CRC Error Drop (cCdmaAhdlcCRCDropPkts)

Insufficient Memory During Encoding (cCdmaAhdlcMemDropPktsDec)

Insufficient Memory During Decoding (cCdmaAhdlcMemDropPktsEnc)

Queue Overflow During Encoding (cCdmaAhdlcOverflowDropPktsDec)

Queue Overflow During Decoding (cCdmaAhdlcOverflowDropPktsEnc)

Invalid Size During Encoding (cCdmaAhdlcInvSizeDropPktsDec)

Invalid Size During Decoding (cCdmaAhdlcInvSizeDropPktsEnc)

### Decoding Drop (cCdmaAhdlcDropPktsDec)

Number of packets dropped by the engine during asynchronous high-level data link control (AHDLC) decoding since system was last restarted.

The counter value could have discontinuities when the management system is reinitialized and at other times as shown by the value of cCdmaAhdlcDiscontinuityTime.

### Encoding Drop (cCdmaAhdlcDropPktsEnc)

Number of packets dropped by the engine during asynchronous high-level data link control (AHDLC) encoding since system was last restarted.

The counter value could have discontinuities when the management system is reinitialized and at other times as shown by the value of cCdmaAhdlcDiscontinuityTime.

### CRC Error Drop (cCdmaAhdlcCRCDropPkts)

Number of packets dropped by the engine during asynchronous high-level data link control (AHDLC) encoding since system was last restarted.

The counter value could have discontinuities when the management system is reinitialized and at other times as shown by the value of cCdmaAhdlcDiscontinuityTime.

### Insufficient Memory during encoding (cCdmaAhdlcMemDropPktsDec)

Number of packets dropped by the engine because of insufficient memory during asynchronous high-level data link control (AHDLC) decoding since system was last restarted.

The counter value could have discontinuities when the management system is reinitialized and at other times as shown by the value of cCdmaAhdlcDiscontinuityTime.

### Insufficient Memory during decoding (cCdmaAhdlcMemDropPktsEnc)

Number of packets dropped by the engine because of insufficient memory during asynchronous high-level data link control (AHDLC) encoding since system was last restarted.

The counter value could have discontinuities when the management system is reinitialized and at other times as shown by the value of cCdmaAhdlcDiscontinuityTime.

### Queue Overflow during encoding (cCdmaAhdlcOverflowDropPktsDec)

Number of packets dropped by the engine because of queue overflow during asynchronous high-level data link control (AHDLC) decoding since system was last restarted.

The counter value could have discontinuities when the management system is reinitialized and at other times as shown by the value of cCdmaAhdlcDiscontinuityTime.

### Queue Overflow during decoding (cCdmaAhdlcOverflowDropPktsEnc)

Number of packets dropped by the engine because of queue overflow during asynchronous high-level data link control (AHDLC) encoding since system was last restarted.

The counter value could have discontinuities when the management system is reinitialized and at other times as shown by the value of cCdmaAhdlcDiscontinuityTime.

### Invalid Size during encoding (cCdmaAhdlcInvSizeDropPktsDec)

Number of packets dropped by the engine because of invalid size during asynchronous high-level data link control (AHDLC) decoding since system was last restarted.

The counter value could have discontinuities when the management system is reinitialized and at other times as shown by the value of cCdmaAhdlcDiscontinuityTime.

### Invalid Size during decoding (cCdmaAhdlcInvSizeDropPktsEnc)

Number of packets dropped by the engine because of invalid size during asynchronous high-level data link control (AHDLC) encoding since system was last restarted.

The counter value could have discontinuities when the management system is reinitialized and at other times as shown by the value of cCdmaAhdlcDiscontinuityTime.
