• FIP keepalive (FKA) advertisement timeout.
NOTE: In each FCoE map, the fabric ID, FC-MAP value, and FCoE VLAN must be unique. To access one SAN fabric, use
one FCoE map. You cannot use the same FCoE map to access dierent fabrics.
When you congure an S5000 as an NPG, FCoE transit with FIP snooping is automatically enabled and congured using the
parameters in the FCoE map applied to server-facing Ethernet and fabric-facing FC interfaces (refer to FIP Snooping on an NPIV
Proxy Gateway).
After you apply an FCoE map on an FC port, when you enable the port (using the no shutdown command), the NPG starts
sending FIP multicast advertisements on behalf of the FC port to downstream servers to advertise the availability of a new FCF port
on the FCoE VLAN. The FIP advertisement also contains a keepalive message to maintain connectivity between a SAN fabric and
downstream servers.
Congure an NPIV Proxy Gateway
You can directly connect an NPIV proxy gateway to a server or a server over a FIP snooping bridge.
If you connect the S5000 and a FIP snooping bridge using a port channel, congure the port channel on both devices (the
interface port-channel command on the S5000).
NOTE: DCB is enabled by default. Auto-negotiated DCBx is enabled for converged trac by default on all S5000
Ethernet ports. FCoE transit with FIP snooping is automatically enabled when you congure Fibre Channel capability
(refer to Enabling Fibre Channel Capability on the Switch).
To congure NPG operation, follow these conguration steps:
1. Enabling Fibre Channel Capability on the Switch
2. Creating a DCB Map
3. Applying a DCB Map on Server-Facing Ethernet Ports
4. Creating an FCoE VLAN
5. Applying an FCoE Map on Server-Facing Ethernet Ports
6. Applying an FCoE Map on Fabric-Facing FC Ports
Enabling Fibre Channel Capability on the Switch
To congure as an NPG for the Fibre Channel protocol, you must rst enable an S5000 switch.
When you enable Fibre Channel capability, FCoE transit with FIP snooping is automatically enabled on all VLANs on the switch, using
the default FCoE transit settings. For more information, refer to Enable FIP Snooping on VLANs.
• Enable the switch for the Fibre Channel protocol.

Creating a DCB Map
Congure the priority-based ow control (PFC) and enhanced trac selection (ETS) settings in a DCB map before you apply them
on downstream server-facing ports on an NPG.
1. Create a DCB map to specify PFC and ETS settings for groups of dot1p priorities.

2. Congure the PFC setting (on or o) and the ETS bandwidth percentage allocated to trac in each priority group or whether
priority group trac should be handled with strict-priority scheduling.
