Fabric OS features in Access Gateway mode

Table 3

describes the authentication behavior between a sending HBA and receiving AG switch.

Supported Fabric OS commands

All Fabric OS commands for authentication policy apply to AG switches, including the following:

•

authutil -- policy

•

authutil --show

•

authutil --set

•

secauthsecret --set

•

secauthsecret --show

NOTE

Although authutil --authinit is not supported in AG mode, it is supported in native mode.

For more information, refer to the

Fabric OS Command Reference

Limitations and considerations

•

Authentication policy is not supported on cascaded AG switch configurations.
