6.1.29 ADMINISTER SECURITY BANNER
Syntax: banner [clear] [L#=”Line # Message”]
The banner command is only visible when the unit is logged. It is used to administer the
security banner. The default is a NULL banner. If a security banner is configured, it is
displayed at each user login. The clear option is a shortcut to erase the entire message.
6.1.30 CLOSED USER GROUP (CUG) ADMINISTRATION
Syntax: cug < cug num > [ ipaddr=< ip address > ]
[ submask=< ip submask >]
The
cug command is only visible when the unit is logged in. The <CUG_num>
parameter is the closed user group identifier used to assign the CUG to a user port (with
the
port command), or the console (with the console command). The <CUG_num>
may be a value between 1 and 16, inclusive.
A single IP address and subnet mask pair specifies each CUG. The ipaddr parameter is
an address of an endpoint (or base address of a group of endpoints) to be allowed into
the group. The ipaddr value ANDed with the submask value must agree with the
caller’s or destination’s IP address ANDed with the same submask for a call to be
allowed to or from a user port to which the CUG is assigned. Depending on the
submask value, this allows an individual (submask=255.255.255.255), intermediate, or
network-wide level of authorization.
Setting the ipaddr value to 0.0.0.0 deletes any prior configuration for the <CUG_num>.
A <CUG_num> may not be deleted if it is currently assigned to any user port.
A list of all configured CUGs is reported via the
vfy cug command. The list of closed
user groups associated with a given user port is presented in response to the vfy port
command.
6.1.31 VERIFY CUG
Syntax: vfy cug
This command is only visible when the unit is logged in. It displays the configuration of
all Closed User Groups.
6.1.32 ASSIGNING A CUG TO THE CONSOLE
Syntax: console cug=<+|->< cug num >
The
console command is only visible when the unit is logged in. The <CUG_num>
parameter is the closed user group identifier as defined with the cug command. A prefix
