OMMUNITY TRINGS
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
u
only able to retrieve MIB objects.
private - with read/write access. Authorized management stations are
u
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>.
Console(config)#snmp-server community admin rw
Console(config)#snmp-server community private
Console(config)#
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.

RAP ECEIVERS
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}}]"
