The name identifying the privilege group. In most cases, a privilege level group consists of a single module (e.g. LACP,
RSTP or QoS), but a few of them contain more than one. The following description defines the privilege level groups in
details:
System: Contact, Name, Location, Time zone, Log.
Security: Authentication, System Access Management, Port (contains Dot1x port, MAC based and the MAC Address
Limit), ACL, HTTPS, SSH, ARP Inspection and IP source guard.
IP: Everything except 'ping'.
Port: Everything except 'VeriPHY'.
Diagnostics: 'ping' and 'VeriPHY'.
Maintenance: System Reboot, System Restore Default, System Password, Configuration Save, Configuration Load and
Firmware Load. Web- Users, Privilege Levels and everything in Maintenance.
Privilege Levels
Every group has an authorization privilege level for the following sub groups: configuration read-only, configuration/execute
read-write, status/statistics read-only, status/statistics read-write (e.g. for clearing of statistics). User privilege should be
equal or greater than the authorization Privilege level to have the access to that group.
4.4 IP
IP is an acronym for Internet Protocol. It is a protocol used for communicating data across an internet network.
IP is a "best effort" system, which means that no packet of information sent over is assured to reach its destination in
the same condition it was sent. Each device connected to a Local Area Network (LAN) or Wide Area Network (WAN) is
given an Internet Protocol address, and this IP address is used to identify the device uniquely among all other devices
connected to the extended network.
The current version of the Internet protocol is IPv4, which has 32-bits Internet Protocol addresses allowing for in excess
of four billion unique addresses. This number is reduced drastically by the practice of webmasters taking addresses in
large blocks, the bulk of which remain unused. The new version of the Internet Protocol, IPv6, which has 128-bits Internet
Protocol addresses. This number can be represented roughly by a three with thirty-nine zeroes after it.
4.4.1 IPv4
The IPv4 address for the switch could be obtained via DHCP Server for VLAN 1. To manually configure an address, you
need to change the switch's default settings to values that are compatible with your network. You may also need to
establish a default gateway between the switch and management stations that exist on another network segment.
Web Interface
To configure an IP address in the web interface:
1. Click System, IP Configuration.
2. Specify the IPv4 settings, and enable DNS proxy service if required.
3. Click Apply.
The Configured column is used to view or change the IP configuration.
The Current column is used to show the active IP configuration.
