Dell PowerEdge FX2/FX2s - Manual (Page 74)

– Each FIP snooping port is auto-configured to operate in Hybrid mode so that it accepts both
tagged and untagged VLAN frames.
– Tagged VLAN membership is auto-configured on each FIP snooping port that sends and receives
FCoE traffic and has links with an FCF, ENode server or another FIP snooping bridge.
– The default VLAN membership of the port should continue to operate with untagged frames. FIP
snooping is not supported on a port that is configured for non-default untagged VLAN
membership.
FIP Snooping Restrictions
The following restrictions apply to FIP snooping on an Aggregator:
• The maximum number of FCoE VLANs supported on the Aggregator is eight.
• The maximum number of FIP snooping sessions supported per ENode server is 32. To increase the
maximum number of sessions to 64, use the fip-snooping max-sessions-per-enodemac
command. This is configurable only in PMUX mode.
• In a full FCoE N port ID virtualization (NPIV) configuration, 16 sessions (one FLOGI + 15 NPIV sessions)
are supported per ENode. In an FCoE NPV confguration, only one session is supported per ENode.
• The maximum number of FCFs supported per FIP snooping-enabled VLAN is 12.
• Links to other FIP snooping bridges on a FIP snooping-enabled port (bridge-to-bridge links) are not
supported on the Aggregator.
Configuring FIP Snooping
You can enable FIP snooping globally on all FCoE VLANs on a switch or on an individual FCoE VLAN.
By default, FIP snooping is disabled.
To enable FCoE transit on the switch and configure the FCoE transit parameters on ports, follow these
steps.
1. Enable the FCoE transit feature on a switch.
CONFIGURATION mode.

2. Enable FIP snooping on all VLANs or on a specified VLAN.
CONFIGURATION mode or VLAN INTERFACE mode.
fip-snooping enable
By default, FIP snooping is disabled on all VLANs.
3. Configure the FC-MAP value used by FIP snooping on all VLANs.
CONFIGURATION VLAN or INTERFACE mode
fip-snooping fc-map fc-map-value
The default is 0x0EFC00.
The valid values are from 0EFC00 to 0EFCFF.
4. Enter interface configuration mode to configure the port for FIP snooping links.
