Configuring an FCIP tunnel
27
• Routers and firewalls must be configured to pass ARP, ICMP, and IP layer 3 protocols.
• Persistently disable the VE_Ports before you configure them. Ports on a new Extension Switch
or Extension Blade are persistently disabled by default.
• Determine which features you are implementing, and gather the information needed to
implement those features.
Table 114 summarizes feature support per FCIP platform.
Virtual Port Types
Virtual ports may be defined as VE_Ports or VEX_Ports.
VE_Ports
VE_Ports (virtual E_Ports) are used to create interswitch links (ISLs) through an FCIP tunnel. If
VE_Ports are used on both ends of an FCIP tunnel, the fabrics connected by the tunnel are
merged.
VEX_Port
A VEX_Port enables FC-FC Routing Service functionality over an FCIP tunnel. VEX_Ports enable
interfabric links (IFLs). If a VEX_Port is on one end of an FCIP tunnel, the fabrics connected by
the tunnel are not merged. The other end of the tunnel must be defined as a VE_Port.
Configuring an FCIP tunnel
When you configure an FCIP extension connection, you create FCIP tunnels and FCIP circuits
between two Extension Switches.
1. Select Configure > FCIP Tunnels.
The FCIP Tunnels dialog box is displayed ( Figure 542 ).
