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 <Enter>. (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

<Enter>.

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.
