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.
