Table 22 Port Statistics data window entries (continued)

Entry

Description

 

 

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 equals

Address

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 re-initialize the loop. An L_port, identified by

 

AL_PS, may have noticed a performance degradation and is

 

trying to restore the loop.

 

 

LIP(f7,f7)

A loop initialization primitive frame used to acquire an AL_PA

 

 

LIP(f8,AL_PS)

This LIP denotes a loop failure detected by the L_port identified

 

by AL_PS

 

 

LIP(f8,f7)

A loop initialization primitive frame used to indicate that a Loop

 

Failure has been detected at its receiver and does not have a

 

valid AL_PA

 

 

Login Count

Number of device logins that have occurred on the switch

 

 

Logout Count

Number of device logouts that have occurred on the switch

 

 

Loop Timeouts

Number of loop timeouts

 

 

Loss Of Sync

Number of synchronization losses (>100 ms) detected by this

 

port. A loss of synchronization is detected by receipt of an invalid

 

transmission word.

 

 

Primitive Sequence

Number of bad primitives received by the port

Errors

 

 

 

Rx Link Resets

Number of link reset primitives received from an attached device

 

 

Rx Offline Sequences

Number of offline sequence primitives received by the port

 

 

Total Errors

Total number of primitive and non-primitive port link errors

 

 

Total Link Resets

Number of link-reset primitives transmitted and received by the

 

port

 

 

Total LIPs Received

Number of loop initialization primitive frames received

 

 

Total LIPs Transmitted

Number of loop initialization primitive frames transmitted

 

 

Tx Offline Sequences

Number of offline primitives transmitted by the port
