Table 86 shows the default mapping of DSCP priorities to L2Cos priorities per tunnel ID. This may be helpful when consulting with the network administrator. These values may be modified per FCIP tunnel.

IPSec supports network-level data integrity, data confidentiality, data origin authentication, and replay protection. It helps secure your SAN against network-based attacks from untrusted computers, attacks that can result in the denial-of-service of applications, services, or the network, data corruption, and data and user credential theft. By default, when creating an FCIP tunnel, IPSec is disabled. Used to provide greater security in tunneling on an FR4-18i blade or a 400 Multi-protocol Router , the IPSec feature does not require you to configure separate security for each application that uses TCP/IP. When configuring for IPSec, however, you must ensure that there is an FR4-18i blade or a 400 Multi-protocol Router at each end of the FCIP tunnel. IPSec works on FCIP tunnels with or without IP compression (IPComp), FCIP fastwrite, and tape pipelining. IPSec requires an IPSec license in addition to the High-Performance Extension over FCIP/FC license. Fabric OS 6.1.x administrator guide 379
