Community Strings (for SNMP version 1 and 2c clients)
Community strings are used to control management access to SNMP
version 1 and 2c stations, as well as to authorize SNMP stations to receive
trap messages from the switch. You therefore need to assign community
strings to specified users, and set the access level.
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 <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.
