20 Configuring and monitoring FCIP extension services This chapter describes the FCIP concepts, configuration procedures, and tools and procedures for monitoring network performance. Commands described in this chapter require Admin or root user access. See the Fabric OS Command Reference for detailed information on command syntax. FCIP concepts Fibre Channel over IP (FCIP) enables you to connect Fibre Channel SANs over IP-based networks. 400 Multi-protocol Router and Multi-Protocol blade (FR4-18i) use FCIP to encapsulate Fibre Channel frames within IP frames that can be sent over an IP network to a partner 400 Multi-protocol Router or FR4-18i blade. When the IP packets are received, the Fibre Channel frames are reconstructed. The Fibre Channel fabric and all Fibre Channel targets and initiators are unaware of the presence of the IP network. Virtual ports and FCIP tunnels Each FR4-18i and 400 Multi-protocol Router platform presents 16 FC ports and 16 virtual ports. Each GbE interface can support up to 8 FCIP tunnels, which are represented as 8 Virtual ports on ge0 and 8 virtual ports on ge1. The mapping of Tunnels on ge0 and ge1 to virtual port numbers is shown in Table 84. Table 84 Tunnel and virtual port numbering GbE port Tunnels Virtual ports ge0 0 16 1 17 2 18 3 19 4 20 5 21 6 22 7 23 ge1 0 24 1 25 2 26 3 27 4 28 5 29 6 30 7 31 Virtual port types Virtual ports may be defined as VE_Ports or VEX_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. Fabric OS 6.1.x administrator guide 385
