58  Configuring & Monitoring the Switch

ELS100-24TXM

Setting SNMP Management Access 

Access to the ELS100-24TXM switch through SNMP is controlled by 
community names. The community names set for the switch must match 
those used by the SNMP management station for successful 
communication to occur. The switch uses two community names. The 
“Public” community name allows read-only access to the device via 
SNMP. The “Private” community name allows read/write access.

The ELS100-24TXM switch can send SNMP messages called traps to 
SNMP management stations when an important event occurs with the 
switch. The switch allows up to four destinations to be configured for 
these trap messages to be sent.

To configure SNMP access for the switch, do the following:

1.

Select System Configuration Menu from the Main Menu.

2.

Select SNMP Configuration Menu.

3.

Select SNMP Private Community Name from the menu and enter the 
desired read/write access community name (you are permitted to 
enter from one to 10 characters).

4.

Select SNMP Public Community Name and enter the desired read-
only community name (you are permitted to enter from one to 10 
characters).

5.

Select one or more Trap Destination entries from the menu and enter 
the appropriate IP addresses.

6.

For each trap destination entered, a corresponding community name 
should be entered.

Viewing Switch Statistics

To view switch statistics, do the following:

1.

Select Switch Statistics Screen from the Main Menu.

The screen lists the main statistical counts for all ports on the switch 
simultaneously.

2.

Select Switch Summary from the Switch Statistics Screen.

The screen lists a summary of sum total statistics for all ports on the 
switch.

3.

Select Port Statistics from the Switch Statistics Screen.

4.

Enter the port number. Press [Enter].

The screen lists expanded port-level statistics for an individual port.

5.

On any of the statistics screens, select Clear to clear (zero) the 
displayed statistical counts and Refresh to refresh (update) the 
displayed statistical counts.
