# SRP Physical Layer Errors

Use this option to monitor physical medium dependent layer error statistics traffic reception for the current interval of a particular side of a particular SRP interface.

## Procedure

> 1. Right-click the SRP interface and select Monitor from the popup menu.

> The Monitor Port dialog box appears.

> 2. Select Error Statistics - Current Interval from the Category menu.

> The Error Statistics - Current Interval dialog box appears.

3. Select Interface Side.

4. Click Monitor button.

5. Select Physical Layer Errors from the Category menu.

The Error Statistics - Current Interval dialog box for that particular side displays the following physical layer error information:

TTL Exp. Packet Discard (srpErrCntCurrRingRxTtlExpPkts)

Short Packets (srpErrCntCurrRingRxShortPkts)

Giant Packets (srpErrCntCurrRingRxGiantPkts)

Aborted Packets (srpErrCntCurrRingRxAbortPkts)

CRC Error Packets (srpErrCntCurrRingRxCRC)

SRP Higher Layer Errors

### TTL Exp. Packet Discard (srpErrCntCurrRingRxTtlExpPkts)

Number of packets discarded due to TTL expiry, received from the physical medium dependent layer during a 15 minute interval.

### Short Packets (srpErrCntCurrRingRxShortPkts)

Number of short packets, received from the physical medium dependent layer during a 15 minute interval. A short packet is 16 octets or less.

### Giant Packets (srpErrCntCurrRingRxGiantPkts)

Number of giant packets, received from the physical medium dependent layer during a 15 minute interval. A giant packet is larger than the maximum packet size which is 9216 octets.

### Aborted Packets (srpErrCntCurrRingRxAbortPkts)

Number of aborted packets, received from the physical medium dependent layer during a 15 minute interval. Aborted packets are packets that are aborted by an abort sequence code.

### CRC Error Packets (srpErrCntCurrRingRxCRC)

Number of packets with CRC errors, received from the physical medium dependent layer during a 15 minute interval.
