| 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. |

| What: /sys/bus/fcoe/fcf_X |
| Date: March 2012 |
| KernelVersion: TBD |
| Contact: Robert Love <robert.w.love@intel.com>, devel@open-fcoe.org |
| 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. |
