Table 5-5. Port Statistics Data Window Entries (Continued)

 

 

 

 

 

Entry

Description

 

 

 

 

 

 

Class 3 Toss

Number of class 3 frames that were discarded by this port. A

 

 

 

 

frame can be discarded because of detection of a missing

 

 

 

 

frame (based on SEQ_CNT), detection of an E_D_TOV

 

 

 

 

timeout, receiving a reject frame, or receiving a frame on an

 

 

 

 

offline port.

 

 

Class 3 Words In

Number of class 3 words received by this port.

 

 

Class 3 Words Out

Number of class 3 words transmitted by this port.

 

 

Decode Errors

Number of invalid transmission words detected during

 

 

 

 

decoding. Decoding is from the 10-bit characters and special K

 

 

 

 

characters.

 

 

Ep Connects

Number of E_Port logins.

 

 

FBusy

Number of class 2 and class 3 fabric busy (F_BSY) frames

 

 

 

 

generated by this port in response to incoming frames. This

 

 

 

 

usually indicates a busy condition on the fabric or N_port that

 

 

 

 

is preventing delivery of this frame.

 

 

Flow Errors

Number of times a frame is received and all the switch ports

 

 

 

 

receive buffers are full. The normal Fabric Login exchange of

 

 

 

 

flow control credit should prevent this from occurring. The

 

 

 

 

frame will be discarded.

 

 

FReject

Number of frames, from devices, that have been rejected.

 

 

 

 

Frames can be rejected for any of a large number of reasons.

 

 

Invalid CRC

Number of invalid Cyclic Redundancy Check (CRC) frames

 

 

 

 

detected.

 

 

Invalid Destination

Number of address identifier (S_ID, D_ID) errors. AL_PA

 

 

Address

equals non-zero AL_PA found on F_Port.

 

 

Link Failures

Number of optical link failures detected by this port. A link

 

 

 

 

failure is a loss of synchronization or by loss of signal while not

 

 

 

 

in the offline state. A loss of signal causes the switch to

 

 

 

 

attempt to re-establish the link. If the link is not re-established,

 

 

 

 

a link failure is counted. A link reset is performed after a link

 

 

 

 

failure.

 

 

LIP (AL_PD,AL_PS)

Number of F7, AL_PS LIPs, or AL_PD (vendor specific) resets,

 

 

 

 

performed.

 

 

LIP(f7,AL_PS)

This LIP is used to reinitialize the loop. An L_port, identified by

 

 

 

 

AL_PS, may have noticed a performance degradation and is

 

 

 

 

trying to restore the loop.
