Access rights and levels

Most CCM commands require the user to have access rights to use the commands. The access rights for each CCM command are listed in Chapter 4. The following table describes the access rights a user may be given.

Access Rights

Access Right	Description
PCON	The Port Conﬁguration access right should be given to users who
	must modify port settings. Grant PCON access rights only to users
	who need to issue the Port Set command.

SCON	The Server Conﬁguration access right should be given to users
	who must change the CCM conﬁgurations, including setting the
	IP address and updating the CCM program load in FLASH. Grant
	SCON access only to users who need to administer the CCM.

SMON	The Server Monitor access right should be given to users who need
	to view CCM status and monitor serial port activity. Grant SMON
	access only to users who need to assist other users in accessing
	attached serial devices.

USER	The User access right should be given to users who need to modify
	the user database. Grant USER access only to users who must add,
	change or delete user accounts. At least one user must have USER
	access rights; otherwise, the user database cannot be changed.

BREAK	The Break access right allows users to send a serial break sequence
	to the attached serial device. On certain devices, this sequence has
	a special meaning. Grant BREAK access only to users who need to
	use the Port Break command.

PThe Port access right gives users access to one or more serial ports. This confers the right to access that serial port and connect to the attached serial device. You may grant Port access rights to speciﬁc ports (Pn), a range of ports (Px-y) or all ports (PALL).

The Admin user is preconfigured in the user database with all access rights.

Access levels

When you specify a user’s access rights, you may either specify the individual rights or you may use a shortcut that specifies an access level. The APPLIANCEADMIN and ADMIN levels (which are used in AVWorks in lieu of individual specifications other than port access rights) are equivalent to the following individual specifications:

•The APPLIANCEADMIN level is equivalent to PALL, USER, SCON, SMON, PCON and BREAK.

•The ADMIN level is equivalent to PALL, USER, SMON, PCON and BREAK.
