Administrator Guide

• To assign a MAC address to an FCoE end-device (server ENode or storage device) after a server successfully logs in, set the
FCoE MAC address prex (FC-MAP) value an FCF uses.
• To provide more port security on ports that are directly connected to an FCF and have links to other FIP snooping bridges, set
the FCF or Bridge-to-Bridge Port modes.
• To ensure that they are operationally active, check FIP snooping-enabled VLANs.
• Process FIP VLAN discovery requests and responses, advertisements, solicitations, FLOGI/FDISC requests and responses,
FLOGO requests and responses, keep-alive packets, and clear virtual-link messages.
FIP Snooping in a Switch Stack
FIP snooping supports switch stacking as follows:
• A switch stack conguration is synchronized with the standby stack unit.
• Dynamic population of the FCoE database (ENode, Session, and FCF tables) is synchronized with the standby stack unit. The
FCoE database is maintained by snooping FIP keep-alive messages.
• In case of a failover, the new master switch starts the required timers for the FCoE database tables. Timers run only on the
master stack unit.
NOTE: As a best practice, Dell Networking recommends not conguring FIP Snooping on a stacked MXL switch.
Using FIP Snooping
There are four steps to congure FCoE transit.
1. Enable the FCoE transit feature on a switch to maintain FIP snooping information on the switch.
2. Enable FIP snooping globally on all virtual local area networks (VLANs) or individual VLANs on a FIP snooping bridge.
3. Congure the FC-Map value applied globally by the switch on all VLANs or an individual VLAN.
4. Congure FCF mode for a FIP snooping bridge-to-FCF link.
For a sample FIP snooping conguration, refer to Conguring FIP Snooping.
Important Points to Remember
• Enable DCBx on the switch before enabling the FIP Snooping feature.
• To enable the feature on the switch, congure FIP Snooping.
• To allow FIP frames to pass through the switch on all VLANs, enable FIP snooping globally on a switch.
• A switch can support a maximum eight VLANs. Congure at least one FCF/bridge-to-bridge port mode interface for any FIP
snooping-enabled VLAN.
• You can congure multiple FCF-trusted interfaces in a VLAN.
• When you disable FIP snooping:
– ACLs are not installed, FIP and FCoE trac is not blocked, and FIP packets are not processed.
– The existing per-VLAN and FIP snooping conguration is stored. The conguration is re-applied the next time you enable the
FIP snooping feature.
Enabling the FCoE Transit Feature
The following sections describe how to enable FCoE transit.
NOTE: FCoE transit is disabled by default. To enable this feature, you must follow the Conguring FIP Snooping
procedure.
As soon as you enable the FCoE transit feature on a switch-bridge, existing VLAN-specic and FIP snooping congurations are
applied. The FCoE database is populated when the switch connects to a converged network adapter (CNA) or FCF port and
