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.
Then press <Enter>. For a more detailed description of these parameters,
Console(config)#snmp-server community admin rw
Console(config)#snmp-server community private
