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.

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.
