FIP Snooping | 107
FIP Snooping Example
Figure 8-11 shows an Aggregator used as a FIP snooping bridge for FCoE traffic between an ENode
(server blade) and an FCF (ToR switch). The ToR switch operates as an FCF and FCoE gateway.
Figure 8-11. Example: FIP Snooping on an Aggregator
In Figure 8-11, DCBX and PFC are enabled on the Aggregator (FIP snooping bridge) and on the FCF ToR
switch. On the FIP snooping bridge, DCBX is configured as follows:
• A server-facing port is configured for DCBX in an auto-downstream role.
• An FCF-facing port is configured for DCBX in an auto-upstream or configuration-source role.
The DCBX configuration on the FCF-facing port is detected by the server-facing port and the DCB PFC
configuration on both ports is synchronized. For more information about how to configure DCBX and PFC
on a port, refer to FIP Snooping.
After FIP packets are exchanged between the ENode and the switch, a FIP snooping session is established.
ACLS are dynamically generated for FIP snooping on the FIP snooping bridge/switch.
