read/write access to the entire MIB tree. However, you may assign new views to
version 1 or 2c community strings that suit your specific security requirements (see
page 3-48).
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
- Specifies read-only access. Authorized management stations are only
able to retrieve MIB objects.
•
private
- Specifies 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.
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
Console(config)#snmp-server community admin rw
Console(config)#snmp-server community private
Console(config)#
