Chapter 5: System Configuration
Parameter Description
Group Name: The name identifying the privilege group. In most cases, a privilege level group consists of a single module (for
example, LACP, SMTP or QoS), but a few of them contain more than one. The following description defines these privilege level
groups in details:
System: Contact, Name, Location, Timezone, 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.”
Ports: 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 subgroups: 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 same or greater than the authorization privilege level to have the access to that group.
5.4 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 sure 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-bit IP addresses allowing for more than 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. There is a rather substantial movement to adopt a new version of the Internet Protocol, IPv6, which
would have 128-bit IP addresses. This number can be represented roughly by a three with thirty-nine zeroes after it. However,
IPv4 is still the protocol of choice for most of the Internet.
5.4.1 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.
Configure the switch-managed IP information in the screen shown in Figure 5-8.
The “Configured” column is used to view or change the IP configuration.
The “Current” column is used to show the active IP configuration.
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 “Save.”
