Configuring Data Center Bridging Features 827
a FIP session requires that an untagged VLAN exist on all FIP-enabled ports,
in addition to the VLAN that carries established FIP sessions. FIP snooping
must be enabled on all VLANs carrying FIP or FCoE traffic.
When FIP snooping is disabled, received FIP frames are forwarded or flooded
using the normal multicast rules.
NOTE:
FIP Snooping will become operationally active on a port only when priority flow
control is enabled and at least one lossless CoS queue is active.
Configuring the FC Map Value
When configured using fabric provided MAC addresses, FCoE devices
transmit frames containing the FC map value in the upper 24 bits. Only
frames that match the configured FC map value are passed across the VLAN.
Frames with MAC addresses that do not match the FC map value are
discarded.
Configuring Ports for FIP Snooping
To relay the FIP packets received from the hosts toward the Fibre Channel
forwarders (FCFs), such as an FC router that has a direct FC link into
storage, the switch needs to know the interfaces the FCFs are on. By default,
an interface is configured to be a host facing interface, not an FCF facing
interface.
Dell recommends that FCF-facing ports be placed into auto-upstream mode
in order to receive DCBx information and propagate it to the Converged
Network Adaptors (CNAs) on the auto-downstream ports. Interfaces enabled
for PFC should be configured in trunk mode and must be PFC operationally
enabled before FCoE traffic can pass over the port.
To configure a port channel for FIP snooping, enable DCBX on the member
interfaces in the auto-up role, configure a switchport mode trunk on the port
channel, and enable FIP snooping on the port channel. FIP snooping on a
port channel is supported only when the port channel is directly connected to
an FCF. Since FIP snooping utilizes multicast addresses that are not in the
range of “well-known” multicast addresses, it is necessary to set IGMP
snooping to flood packets addressed to unknown multicast addresses.
