21.5 Public Loop Operation

The drive is designed to perform as a Public NL_Port described in the FLA 2.70 profile.

The drive will:

• tolerate unfairness of a FL_Port

• support 24bit addressing

• accept FAN extended link service

• perform FLOGI to Fabric F_Port (AL_PA = 00h, well known address 0FFFFFEh)

• perform registration to a simple name server (AL_PA = 00h, well known address 0FFFFFCh) using RFC-4 service.

• claim a fabric-assigned AL_PA during LIP in the LIFA sequence

• receive frames from a FL_Port for more than one S_ID in a single loop tenancy

• open L_Port at AL_PA = 00h and send frames to remote port

• use values of E_D_TOV, R_A_TOV as specified by the fabric in FLOGI ACC

Frame Received No PLOGI PLOGI but no PRLI

ABTS Discard and Send LOGO BA_ACC or BA_RJT(1)

ADISC Discard and Send LOGO ACC(2) or LS_RJT

PRLI Discard and Send LOGO ACC

PRLO Discard and Send LOGO ACC or LS_RJT(3)

Unlisted Extended Link Service Discard and Send LOGO ACC or LS_RJT(4)

Note:

1 - The drive returns BA_RJT to ABTS BLS when ABTS BLS has RX_ID other than 0FFFFh

2 - N_Port ID, Port_Name and Node Name must match a logged in port for ACC to be returned.

3 - If PRLI has not been successfully completed, Reason Code = 'Image Pair does not exist'

4 - Unsupported Extended Link Services are rejected.
