2 Basic Configuration The default strings are: • public - with read-only access. Authorized management stations are only able to retrieve MIB objects. • private - with read-write access. Authorized management stations are able to both retrieve and modify MIB objects. To prevent unauthorized access to the switch from SNMP version 1 or 2c clients, it is recommended that you change the default community strings. To configure a community string, complete the following steps: 1. From the Privileged Exec level global configuration mode prompt, type "snmp-server community string mode," where "string" is the community access string and "mode" is rw (read/write) or ro (read only). Press . (Note that the default mode is read only.) 2. To remove an existing string, simply type "no snmp-server community string," where "string" is the community access string to remove. Press . Console(config)#snmp-server community admin rw Console(config)#snmp-server community private Console(config)# 4-102 Note: If you do not intend to support access to SNMP version 1 and 2c clients, we recommend that you delete both of the default community strings. If there are no community strings, then SNMP management access from SNMP v1 and v2c clients is disabled. Trap Receivers You can also specify SNMP stations that are to receive traps from the switch. To configure a trap receiver, use the "snmp-server host" command. From the Privileged Exec level global configuration mode prompt, type: "snmp-server host host-address community-string [version {1 | 2c | 3 {auth | noauth | priv}}]" where "host-address" is the IP address for the trap receiver, "community-string" specifies access rights for a version 1/2c host, or is the user name of a version 3 host, "version" indicates the SNMP client version, and "auth | noauth | priv" means that authentication, no authentication, or authentication and privacy is used for v3 clients. Then press . For a more detailed description of these parameters, see "snmp-server host" on page 4-104. The following example creates a trap host for each type of SNMP client. Console(config)#snmp-server host 10.1.19.23 batman4-104 Console(config)#snmp-server host 10.1.19.98 robin version 2c Console(config)#snmp-server host 10.1.19.34 barbie version 3 auth Console(config)# 2-7
