52CHAPTER 3: ACCESSING THE SWITCH

Configuring SNMP Settings

The following SNMP parameters can be configured on the switch:

Authorized trap receivers — An authorized trap receiver can be one or more network management stations on your network. The switch sends SNMP traps to all trap receivers. You can have a maximum of six trap receivers configured for each switch. Entries in this list can be created, modified, and deleted using the RMON2 trapDestTable MIB variable, as described in RFC 2021.

Authorized managers — An authorized manager can be either a single network management station, or a range of addresses (for example, a complete subnet) specified by a prefix and a mask. The switch can have a maximum of eight authorized managers.

Community strings — The community strings allow a simple method of authentication between the switch and the remote Network Manager. There are two types of community strings on the switch. Read community strings provide read-only access to the switch. The default read-only community string is public. Read-write community strings provide read and write access to the switch. The default read-write community string is private. A total of eight community strings can be configured on the switch. The community string for all authorized trap receivers must be configured on the switch for the trap receiver to receive switch-generated traps. SNMP community strings can contain up to 126 characters.

System contact (optional) — The system contact is a text field that enables you to enter the name of the person(s) responsible for managing the switch.

System name — The system name is the name that you have assigned to this switch. The default name is the model name of the switch (for example, 3C17705).

System location (optional) — Using the system location field, you can enter an optional location for this switch.
