Setting Up SNMP Management

53

The management workstation is connected to the Switch using a port 
in the management VLAN. By default, VLAN 1 is the management 
VLAN containing all ports on the Switch.

You can use the 3Com Network Director application that is available from 
the 3Com website to provide SNMP management for your Switch. If you 
use 3Com Network Director it automatically loads the correct MIBs and 
necessary files onto your workstation.

Pre-requisites

Documentation supplied with the SNMP network management 
application software.

Setting Up SNMP

By default, SNMPv1, SNMPv2c and SNMPv3 are enabled and a local 
engine ID is automatically defined. The local engine ID may be a string 
specified by the user or a generated default string based on the MAC 
address of the device. 

For detailed descriptions of SNMP CLI commands please refer to the 

system management snmp

 menu. Please refer to the Management 

Interface Reference Guide supplied in HTML format on the CD-ROM that 
accompanies your Switch.

To configure SNMPv1 and SNMPv2c

1

Set the desired access level (monitor, manager or security).

2

Ensure the user’s access level is enabled for SNMPv1/2c. 

The access level is enabled by default.

3

Set the community string for that user.

4

Configure your SNMP manager application to use the community string.

To configure SNMPv3

1

Set the desired access level (monitor, manager or security).

2

Ensure the user's access level is enabled for SNMPv3.

The access level is enabled by default.

3

Configure SNMPv3 security for the user, setting the authentication 
protocol, authentication password (if authentication is used), privacy 
protocol and privacy password (if privacy is used).

4

Configure your SNMP manager application to use the username, with the 
settings and passwords.
