E_Port authentication between Fabric OS and M-EOS switches
14
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 57 describes the Fabric OS mode descriptions.
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 56 Fabric OS switch authentication types
Fabric OS authentication types M-EOS support M-EOS switch explanation
FCAP, DH-CHAP Yes M-EOS switch selects the supported DH-CHAP protocol.
FCAP No M-EOS switch does not support FCAP protocol.
DH-CHAP Yes DH-CHAP supported.
TABLE 57 Fabric OS mode descriptions
Fabric OS authentication modes M-EOS support M-EOS switch explanation
Passive Yes The Fabric OS switch participates in the authentication policy
initiated by the M-EOS switch, but does not initiate
authentication.
Active 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.
On 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.
Off Yes Turns off the authentication and the switch rejects any
authentication requests issued from the M-EOS switch.
TABLE 58 DH group types
Fabric OS DH group type M-EOS support M-EOS switch explanation
0, 1, 2, 3, 4 Yes M-EOS selects DH Null option (only supports 0).
0 (DH Null option) Yes 0 (DH Null option) supported.
1 (1024-bit key) No Not supported by M-EOS.
2 (1280-bit key) No Not supported by M-EOS.
3 (1536-bit key) No Not supported by M-EOS.
4 (2048-bit key) No Not supported by M-EOS.
