Changing 9 this value will change the dev_loss_tmo for all 10 FCFs discovered by this controller. 11 12 lesb_link_fail: Link Error Status Block (LESB) link failure count. 13 14 lesb_vlink_fail: Link Error Status Block (LESB) virtual link 15 failure count. 16 17 lesb_miss_fka: Link Error Status Block (LESB) missed FCoE 18 Initialization Protocol (FIP) Keep-Alives (FKA). 19 20 lesb_symb_err: Link Error Status Block (LESB) symbolic error count. 21 22 lesb_err_block: Link Error Status Block (LESB) block error count. 23 24 lesb_fcs_error: Link Error Status Block (LESB) Fibre Channel 25 Serivces error count. 26 27Notes: ctlr_X (global increment starting at 0) 28 29What: /sys/bus/fcoe/fcf_X 30Date: March 2012 31KernelVersion: TBD 32Contact: Robert Love <robert.w.love@intel.com>, devel@open-fcoe.org 33Description: 'FCoE FCF' instances on the fcoe bus. A FCF is a Fibre Channel 34 Forwarder, which is a FCoE switch that can accept FCoE 35 (Ethernet) packets, unpack them, and forward the embedded 36 Fibre Channel frames into a FC fabric. It can also take 37 outbound FC frames and pack them in Ethernet packets to 38 be sent to their destination on the Ethernet segment. 39Attributes: 40 41 fabric_name: Identifies the fabric that the FCF services. 42 43 switch_name: Identifies the FCF. 44 45 priority: The switch's priority amongst other FCFs on the same 46 fabric. 47 48 selected: 1 indicates that the switch has been selected for use; 49 0 indicates that the swich will not be used. 50 51 fc_map: The Fibre Channel MAP 52 53 vfid: The Virtual Fabric ID 54 55 mac: The FCF's MAC address 56 57 fka_peroid: The FIP Keep-Alive peroid 58 59 fabric_state: The internal kernel state 60 "Unknown" - Initialization value 61 "Disconnected" - No link to the FCF/fabric 62 "Connected" - Host is connected to the FCF 63 "Deleted" - FCF is being removed from the system 64 65 dev_loss_tmo: The device loss timeout peroid for this FCF. 66 67Notes: A device loss infrastructre similar to the FC Transport's 68 is present in fcoe_sysfs. It is nice to have so that a 69 link flapping adapter doesn't continually advance the count 70 used to identify the discovered FCF. FCFs will exist in a 71 "Disconnected" state until either the timer expires and the 72 FCF becomes "Deleted" or the FCF is rediscovered and becomes 73 "Connected." 74 75 76Users: The first user of this interface will be the fcoeadm application, 77 which is commonly packaged in the fcoe-utils package. 78
