This means, for example, that the set of managers allowed via Telnet may be
different than the set of Web-based managers which is, in turn, may be
different than the set of secure-web based managers, and so on.
A specific management access method may be completely disabled by
denying all user access to it (e.g. denying all users access to CLI/Telnet
management effectively disables CLI/Telnet as an available management
interface to the system).
By default, management access to the system, through all methods, is
enabled over all interfaces.
NOTE:
If you enable management access through a physical port, all VLANs and
IP interfaces on that port will be acceptable management traffic sources. If you
enable management access through a VLAN, all ports and IP interfaces on that
VLAN will be acceptable. If specific IP address(es) are specified, only traffic from
the specified IP addresses on the appropriate ports will be accepted.
Access Profiles Rules
Each management access profile is composed of at least one rule, which acts
as a filter, and defines the device management method, interface type, source
IP address, network mask, and the device management access action.
Users can be blocked or permitted management access.
Rule priority sets the order in which the rules are implemented. Assigning an
access profile to an interface denies access via other interfaces. If an access
profile is not assigned to any interface, the device can be accessed by all
interfaces.
A total of 256 rules can be defined for all Management Access profiles.
To add rules to existing access profiles, see "Profile Rules" on page 259.
