FCoE Initialization Protocol

DRAFT: BROCADE CONFIDENTIAL

FCoE login

The Brocade FCoE hardware FCoE login operates as follows:

•

ENodes can log in to the Brocade FCoE hardware using FCoE encapsulated, FC Extended Link 
Service (ELS) frames. FLOGI and FDISC are accepted. Brocade FCoE hardware in the fabric 
maintains the MAC address to WWN/PID mappings per login. Class 2 FLOGI is not supported.

•

FCoE FLOGI—The Brocade FCoE hardware accepts FCoE FLOGI from the ENode. FCoE FLOGI 
ACC is sent to the ENode if the FCMAP matches the VN_port table on the Brocade FCoE 
hardware. Requests are ignored if the FCMAP does not match. The ENode login is added to the 
VN_port table.

•

FCoE FDISC—The Brocade FCoE hardware accepts FCoE FDISC from the ENode. FCoE FDISC 
ACC is sent to the ENode if the FCMAP matches the VN_port table on the Brocade FCoE 
hardware. The FCoE FDISC request is ignored if the FCMAP does not match. The ENode login is 
added to the VN_port table.

•

FCMAP—The Brocade FCoE hardware accepts FCoE FLOGI from the ENode. The FCMAP 
determines which FCoE VLAN is accepted for the FCoE session.

NOTE

Only one FCoE VLAN is supported in the Fabric OS v7.0.0 release.

FCoE logout

The Brocade FCoE hardware FCoE logout operates as follows:

•

ENodes can log out from the Brocade FCoE hardware using the FCoE encapsulated, FC ELS 
frame. Brocade FCoE hardware in the fabric updates the MAC address to WWN/PID mappings 
upon logout. The Brocade FCoE hardware also handles scenarios of implicit logout where the 
ENode has left the fabric without explicitly logging out.

•

FCoE LOGO—The Brocade FCoE hardware accepts the FCoE LOGO from the ENode. The FCoE 
LOGO ACC is sent to the ENode if the ENode MAC address matches the VN_port table on the 
Brocade FCoE hardware. The LOGO is ignored (not rejected) if the ENode MAC address does 
not match. The ENode logout is updated in the VN_port table.

Logincfg

The Brocade FCoE hardware logincfg mechanism operates as follows:

•

The logincfg is the mechanism for controlling ENode logins per Brocade FCoE hardware. Each 
unit of Brocade FCoE hardware maintains its own logincfg. 

•

Login configuration management is optional—when login management is disabled, the default 
behavior is to accept logins from any ENode.

•

Logingroup creation and deletion—The Brocade FCoE hardware accepts valid logingroup 
names and member WWNs. The Brocade FCoE hardware rejects invalid entries. The Brocade 
FCoE hardware allows the deletion of logingroups that are defined and committed. You can 
display defined and committed logingroups. The logingroup capability is disabled by default.

•

Member add and remove—You can add valid member WWNs. Invalid WWNs are rejected. 
Duplicate WWNs are uniquely resolved. You can display the current view of defined logingroups 
when changes are made to the configuration.
