5.72 Port Error and Status CSR n (SPn_ERR_STAT)

Each of the four ports is supported by a register of this type (see Table 146). The port error and status CSR n (SPn_ERR_STAT) is shown in Figure 135 and described in Table 147.

31–27

Reserved

0

These read-only bits return 0s when read.

 

26

OUTPUT_PKT_DROP

 

Output packet drop (switch devices only)

 

 

 

0

The output port has not discarded a packet.

 

 

 

1

The output port has discarded a packet.

 

25

OUTPUT_FLD_ENC

 

Output failed condition encountered. Once set, the OUTPUT_FLD_ENC bit

 

 

 

remains set until software writes a 1 to it.

 

 

 

0

The output port has not encountered a failed condition.

 

 

 

1

The output port has encountered a failed condition. The failed port error

 

 

 

 

threshold has been reached in the Port n Error Rate Threshold Register.

 

24

OUTPUT_DEGRD_ENC

 

Output degraded condition encountered. Once set, the

 

 

 

 

OUTPUT_DEGRD_ENC bit remains set until software writes a 1 to it.

 

 

 

0

The output port has not encountered a degraded condition.

 

 

 

1

The output port has encountered a degraded condition. The degraded port

 

 

 

 

error threshold has been reached in the Port n Error Rate Threshold

 

 

 

 

Register.
