14 E_Port authentication between Fabric OS and M-EOS switches Because M-EOS only supports the DH-CHAP authentication, not all Fabric OS authentication configurations work when connected to an M-EOS switch. With DH-CHAP authentication, you must configure the shared secrets on both switches. For details on procedures to configure shared secrets, see the Chapter 7, "Configuring Security Policies". Table 56 describes the Fabric OS authentication types. TABLE 56 Fabric OS switch authentication types Fabric OS authentication types M-EOS support M-EOS switch explanation FCAP, DH-CHAP Yes FCAP No DH-CHAP Yes M-EOS switch selects the supported DH-CHAP protocol. M-EOS switch does not support FCAP protocol. DH-CHAP supported. Table 57 describes the Fabric OS mode descriptions. TABLE 57 Fabric OS mode descriptions Fabric OS authentication modes M-EOS support M-EOS switch explanation Passive Active On Off Yes The Fabric OS switch participates in the authentication policy initiated by the M-EOS switch, but does not initiate authentication. Yes During switch initialization, authentication is initiated on all E_Ports, but the port is not disabled if the connecting M-EOS switch does not support authentication, for example, if the authentication feature key is not installed on the M-EOS switch. Yes Strict authentication is enforced on all E_Ports. The ISL goes down (port disable) if the connecting M-EOS switch does not support authentication, for example, if the authentication feature key is not installed on the M-EOS switch. Yes Turns off the authentication and the switch rejects any authentication requests issued from the M-EOS switch. NOTE An M-EOS switch can connect to a Fabric OS switch in any of the switch authentication modes. Table 58 describes the DH group types. TABLE 58 DH group types Fabric OS DH group type M-EOS support M-EOS switch explanation 0, 1, 2, 3, 4 Yes 0 (DH Null option) Yes 1 (1024-bit key) No 2 (1280-bit key) No 3 (1536-bit key) No 4 (2048-bit key) No M-EOS selects DH Null option (only supports 0). 0 (DH Null option) supported. Not supported by M-EOS. Not supported by M-EOS. Not supported by M-EOS. Not supported by M-EOS. 312 Fabric OS Administrator's Guide 53-1001763-01
