What are the functions of domain and global default domain

14

The device manages access users based on domains. Each access user belongs to a domain.

The authentication, authorization, and accounting schemes can be bound to the domain views. The device manages the access users in the same domain in the same manner, for example, the same authentication, authorization, and accounting scheme.

The domain of an access user is decided by the user name the user entered in login, and the device authenticates the user according to the domain in the user name. If the user name does not contain a domain name, the device adds the user to the global default domain according to the user access type and authenticates the user based on the configuration of the global default domain.

The administrator (logging in through Telnet, SSH, FTP, HTTP, or Terminal) is authenticated in the global default administrative domain. By default, the global administrative domain is default_admin.

You can run the domain domain-name admin command in the system view to configure the global default administrative domain.

The common users (logging in through MAC, Portal, 802.1x, or PPP authentication) are authenticated in the global default common domain. By default, the global common domain is default.

You can run the domain domain-name command in the system view to configure the global default common domain.

NOTE:
You can modify the configuration of the global default domains by default, but cannot delete the domains.

What are the functions of the domain and global default domain on an S series switch
S series switches (except S1700 switches) manage access users based on domains. Each access user belongs to a domain. The authentication, authorization, and accounting schemes can be bound to domain views. A switch manages the access users in the same domain in the same manner, for example, using the same authentication, authorization, or accounting scheme. The domain of an access user is decided by the user name the user entered for login, and the switch authenticates the user according to the domain in the user name. If the user name does not contain a domain name, the device adds the user to the global default domain according to the user access type and authenticates the user based on the configuration of the global default domain. By default, the global administrative domain is default_admin and the global default domain for common access users is default. You can run the domain domain-name [ admin ] command to modify configurations of the global default domains, but you cannot delete the domains.

What is the default management and authentication domain of the AR router
By default, the global administrative domain (authentication domain of the administrator) on the AR router is default_admin. You can run the domain domain-name admin command in the system view to modify the global default administrative domain.

Functions of the RES and GCC bytes in the ASON domain
The OSPF and RSVP protocols transmit messages through the GCC or RES bytes in OTN overhead. Control links and control channels for the ASON are created in OTN overhead (electrical-layer ASON uses RES_ODU or GCC bytes) and DCC channels (optical-layer ASON uses D4 to D12 bytes).
