System Management
Access List
You may specify that the system administrator can only login from a
specific host or network defined in the list. A maximum of three
IPs/subnet masks may be entered.
IP: Specifies an IP address allowed to login to the router.
Subnet Mask: Specifies a subnet mask allowed to login to
the router.
Port Setup
Default Ports: Check to use standard port numbers for the
Telnet and HTTP servers.
User Defined Ports: Check to specify user-defined port
numbers for the Telnet and HTTP servers.
SNMP Setup
The Simple Network Management Protocol (SNMP) is an
application layer protocol that communicates message between
manager and agent. You can use third-party manager (SNMP
utility) to manage the router. The Management Information Base
(MIB) is an information store that contains network information.
The SNMP agent contains the MIBs that the SNMP manager
can get or set. The agent can send trap messages to the manager
if the Vigor2200USB has a problem. The SNMP uses the
community name for authentication.
