FIP logout
FIP logout operates as follows:
ENodes can log out from the Brocade FCoE hardware using FIP. The Brocade FCoE hardware in 
the fabric updates the MAC address, WWN, and 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.
FIP logout (LOGO)—The Brocade FCoE hardware accepts a FIP LOGO from the ENode. The FIP 
LOGO ACC should be 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. FPMA is supported.
Implicit logout—With the ENode directly connected to a CEE port, if the port that the ENode is 
attached to goes offline, the Brocade FCoE hardware implicitly logs out that ENode. ENode 
logout is updated in the VN_port table. The Brocade FCoE hardware sends FCoE LOGO on 
behalf of the ENode.
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 v6.4.0 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.
