• on an S5000 switch not congured as an NPIV proxy gateway is eight.
• The maximum number of FCFs supported on a FIP snooping-enabled VLAN:
• on an S5000 NPIV proxy gateway is 12.
• on an S5000 switch not congured as an NPIV proxy gateway is 12.
• The maximum number of FIP snooping sessions (including NPIV sessions) supported per ENode server is 64 and is user-congurable.
In a full FCoE NPIV conguration, 64 sessions (one FLOGI + 63 NPIV sessions) are supported per ENode server.
• Links to other FIP snooping bridges on a FIP snooping-enabled port (bridge-to-bridge links) are not supported on the S5000 switch.
• The DCBx version that you congure on an interface determines the server CNA trac that FIP snooping supports on the interface:
• CEE-DCBX supports T11-compliant Gen-2 CNAs.
• CIN-DCBX supports Gen-1 CNAs.
• IEEE 802.1Qaz (Draft 2.5) supports Gen-2 CNAs.
You can also congure an interface to operate using the DCBx version received from a peer (the auto-configure option). In this case,
the S5000 switch detects the capabilities of a CNA and auto-congures the interface to the correct DCBx mode.
Conguring FIP Snooping
You can enable FIP snooping globally on all FCoE VLANs on a switch or on an individual FCoE VLAN in bridge-to-FCF links. By default, FIP
snooping is disabled.
NOTE: When you congure the S5000 as an NPIV proxy gateway and enable Fibre Channel capability (the feature fc
command), FIP snooping is automatically enabled on all VLANs on the switch, using the default FIP snooping settings. Only the
fip-snooping max-sessions-per-enodemac command is supported to congure FIP snooping.
1 Enable the FCoE transit feature on a switch.
CONFIGURATION mode
feature fip-snooping
The default for FCoE transit with FIP snooping is disabled.
2 Enable FIP snooping on all VLANs or on a specied VLAN.
CONFIGURATION mode or VLAN INTERFACE mode
fip-snooping enable
The default for FIP snooping is disabled on all VLANs.
3 Congure the FC-MAP value FIP snooping uses to identify an ENode MAC address on all VLANs.
CONFIGURATION mode or VLAN INTERFACE mode
fip-snooping fc-map fc-map-value
The valid values are from 0EFC00 to 0EFCFF.
The default is 0x0EFC00.
4 Congure the maximum number of FIP-snooping sessions supported on the switch for an ENode MAC address.
CONFIGURATION mode
fip-snooping max-sessions-per-enodemac max-value
Valid values are from 1 to 64.
The default is 32 sessions are supported.
5 Enter the interface conguration level to congure a 10-Gigabit Ethernet or FC port for FIP snooping.
CONFIGURATION mode
