Description: 'FCoE Controller' instances on the fcoe bus
|
|
Attributes:
|
|
|
|
fcf_dev_loss_tmo: Device loss timeout peroid (see below). Changing
|
|
this value will change the dev_loss_tmo for all
|
|
FCFs discovered by this controller.
|
|
|
|
lesb_link_fail: Link Error Status Block (LESB) link failure count.
|
|
|
|
lesb_vlink_fail: Link Error Status Block (LESB) virtual link
|
|
failure count.
|
|
|
|
lesb_miss_fka: Link Error Status Block (LESB) missed FCoE
|
|
Initialization Protocol (FIP) Keep-Alives (FKA).
|
|
|
|
lesb_symb_err: Link Error Status Block (LESB) symbolic error count.
|
|
|
|
lesb_err_block: Link Error Status Block (LESB) block error count.
|
|
|
|
lesb_fcs_error: Link Error Status Block (LESB) Fibre Channel
|
|
Serivces error count.

Description: 'FCoE FCF' instances on the fcoe bus. A FCF is a Fibre Channel
|
|
Forwarder, which is a FCoE switch that can accept FCoE
|
|
(Ethernet) packets, unpack them, and forward the embedded
|
|
Fibre Channel frames into a FC fabric. It can also take
|
|
outbound FC frames and pack them in Ethernet packets to
|
|
be sent to their destination on the Ethernet segment.
|
|
Attributes:
|
|
|
|
fabric_name: Identifies the fabric that the FCF services.
|
|
|
|
switch_name: Identifies the FCF.
|
|
|
|
priority: The switch's priority amongst other FCFs on the same
|
|
fabric.
|
|
|
|
selected: 1 indicates that the switch has been selected for use;
|
|
0 indicates that the swich will not be used.
|
|
|
|
fc_map: The Fibre Channel MAP
|
|
|
|
vfid: The Virtual Fabric ID
|
|
|
|
mac: The FCF's MAC address
|
|
|
|
fka_peroid: The FIP Keep-Alive peroid
|
|
|
|
fabric_state: The internal kernel state
|
|
"Unknown" - Initialization value
|
|
"Disconnected" - No link to the FCF/fabric
|
|
"Connected" - Host is connected to the FCF
|
|
"Deleted" - FCF is being removed from the system
|
|
|
|
dev_loss_tmo: The device loss timeout peroid for this FCF.
|
|
|
|
Notes: A device loss infrastructre similar to the FC Transport's
|
|
is present in fcoe_sysfs. It is nice to have so that a
|
|
link flapping adapter doesn't continually advance the count
|
|
used to identify the discovered FCF. FCFs will exist in a
|
|
"Disconnected" state until either the timer expires and the
|
|
FCF becomes "Deleted" or the FCF is rediscovered and becomes
|
|
"Connected."
|
|
|
|
|
|
Users: The first user of this interface will be the fcoeadm application,
|
|
which is commonly packaged in the fcoe-utils package.
