Multi-hop FIP-snooping bridge
In typical deployments, ENode-connected switches are not directly connected to the core FC switch. Multiple intermediate
switches are connected in between the switches. To establish a point-to-point connection and for secure transmission between
the ENode and the FCF, all intermediate switches must support FSB to pass the FIP and FCoE traffic.
OS10 switches support the multi-hop FIP-snooping bridge. You can interconnect multiple FSBs to communicate with an
upstream FC switch.
● Access FSB— This is the node that is directly connected to ENode. In the following example, FSB1 is the access FSB.
● Core FSB— This is the node that is directly connected to the FCF. In the following example, FSB2 is the core FSB.
The default port mode is the ENode. You must explicitly configure the other modes using the fip-snooping port-mode
command. The following port modes are supported:
● ENode—Only one ENode MAC address per interface can be learnt. Configure this mode on the port connected to the
ENode.
● FCF—If you configure the FSB with FCF port mode, all the FIP packets sent between the ENode and the FCF are snooped
and the sessions and ENodes are learnt. Configure the FCF mode on the access FSB ports connected to the FCF-facing
side.
● ENode-transit—This mode is configured on the intermediate FSBs or Layer 2 (L2) DCBX switches to which ENodes are
connected.
● FCF-transit—Only the FCF advertisement and VLAN responses are snooped to learn the FCF. The FCF-transit does not
learn the ENodes and session information. Configure the FCF-transit mode on the FCF-facing side of the core FSB switch.
The FCF can be in NPG or F-Port mode. The access FSB switches validate the frames and installs ACLs per the FCF to allow
only FCoE and FIP traffic across the FCF.
NOTE:
Port-pinning is not supported on ENodes connected to an FSB switch that is in FCF-transit mode. You cannot view
the ENodes or session information using the show commands.
Clear virtual link frames
When an FSB clears an FCoE session for some reason, the other devices in the network, such as the ENode, FCF, and transit
switches, are not informed and considers the session to be intact. FSB drops the FCoE data corresponding to the cleared
