Gigabit Managed Switch Family Installation Guide

TL-SG3109/TL-SL3428/TL-SL3452

Community string

– Access rights options: ro (read only), rw (read-and-write) or su (super).

– An option to configure IP address or not: If an IP address is not

configured, it means that all community members having the same

community name are granted the same access rights.

Common practice is to use two community strings for the switch one (public

community) with read-only access and the other (private community) with

read-write access. The public string allows authorized management stations

to retrieve MIB objects, while the private string allows authorized management

stations to retrieve and modify MIB objects.

During initial configuration, it is recommended to configure the device

according to the network administrator requirements, in accordance with

using an SNMP-based management station. During the initial configuration

procedure the community-string, community-access, and IP address can be

set through the local terminal.

The SNMP configuration options are:

Community string.

–

Read Only

access.

Configurable IP address. If IP address is not configured, all community

members with the same community name are granted the same access

rights.
