Dell Converged Enhanced Ethernet Administrator’s Guide 11

FCoE Initialization Protocol
1
Logincfg
The Dell FCoE hardware logincfg mechanism operates as follows:
• The logincfg is the mechanism for controlling ENode logins per Dell FCoE hardware. Each unit
of Dell FCoE hardware maintains its own logincfg.
• Login configuration management is optional—when login management is disabled, the default
behavior is to accept logins from any ENode.
• Logingroup creation and deletion—The Dell FCoE hardware accepts valid logingroup names
and member WWNs. The Dell FCoE hardware rejects invalid entries. The Dell FCoE hardware
allows the deletion of logingroups that are defined and committed. You can display defined
and committed logingroups. The logingroup capability is disabled by default.
• Member add and remove—You can add valid member WWNs. Invalid WWNs are rejected.
Duplicate WWNs are uniquely resolved. You can display the current view of defined logingroups
when changes are made to the configuration.
• Commit and abort—Defined logingroup changes can be aborted with no effect on existing
sessions. The Dell FCoE hardware does not apply the configurations to new sessions until the
changes are committed. Once defined, logingroups are committed. The Dell FCoE hardware
immediately uses the new configuration.
• No traffic disruption—Changing the logingroup without committing the changes does not affect
existing sessions. After committing the changes, ENodes that were already logged in continue
to function even when that member is removed from the logingroup. New logins from the
former member are rejected.
Name server
The Dell FCoE hardware name server function operates as follows:
• ENode login and logout to and from the Dell FCoE hardware updates the name server in the FC
fabric. The Dell FCoE hardware maintains the MAC address to WWN/PID mappings.
• ENode login and logout—When an ENode login occurs through any means (FIP FLOGI, FIP
FDISC, FCoE FLOGI, or FCoE FDISC), an entry is added to the name server. When an ENode
logout occurs through any means (FIP LOGO, FCoE LOGO, or implicit logout), the entry is
removed from the name server.
• ENode data—The Dell FCoE hardware maintains a VN_port table. The table tracks the ENode
MAC address, FIP login parameters for each login from the same ENode, and WWN/PID
mappings on the FC side. You can display the VN_port table with the fcoe -loginshow port
command.
FC zoning
The Dell FCoE hardware FC zoning operates as follows:
• The virtual devices created by the Dell FCoE hardware on behalf of the ENodes are subject to
FC zoning. An ENode is only allowed to access devices in the same zones. Administrative
Domains (ADs) are not supported in the Fabric OS v6.3.1_cee release.
• ENodes can access FC devices in the same zones— FC devices that are not in the same zones
cannot be accessed. Zone members can overlap in multiple zones (that is, overlapping zones).
Zoning changes are immediately enabled by hardware enforced zoning.
