Black Box 24 + or 48 + 4-Port Gigabit Managed Switch with SFP+ 10G, LGB5052A, LGB5028A 1 IPv4

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.”
