Configuration manual

The following sections describe how to configure the FIP snooping feature on a switch that functions as
a FIP snooping bridge so that it can perform the following functions:
• Perform FIP snooping (allowing and parsing FIP frames) globally on all VLANs or on a per-VLAN basis.
• 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 prefix (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 configuration 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 configuring FIP Snooping on a stacked
MXL switch.
Using FIP Snooping
There are four steps to configure 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. Configure the FC-Map value applied globally by the switch on all VLANs or an individual VLAN.
4. Configure FCF mode for a FIP snooping bridge-to-FCF link.
For a sample FIP snooping configuration, refer to Configuring FIP Snooping.
Important Points to Remember
• Enable DCBx on the switch before enabling the FIP Snooping feature.
• To enable the feature on the switch, configure 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. Configure at least one FCF/bridge-to-bridge port
mode interface for any FIP snooping-enabled VLAN.
• You can configure multiple FCF-trusted interfaces in a VLAN.
• When you disable FIP snooping:
– ACLs are not installed, FIP and FCoE traffic is not blocked, and FIP packets are not processed.
