You can specify from 0 to 86400 seconds (one day). The default is 3600 (one
hour). If you specify 0, the idle timeout is disabled. The timeout interval is in
30-second increments. For example, the interval can be 0, or 30 seconds, or
60 seconds, or 90 seconds, and so on. If you enter an interval that is not
divisible by 30, the switch rounds up to the next 30-second increment. For
example, if you enter 31, the switch rounds up to 60.
This option applies to all types of CLI management sessions: console,
Telnet, and SSH. The timeout change applies to new sessions only, not to
existing sessions.
4 To configure SNMP settings, go to “Configuring SNMP”. Otherwise, click
Save .
Configuring SNMP On each switch in the network plan, you must enable notifications and
configure 3WXM Services as a notification target (trap receiver). 3WXM
Services does not start listening for SNMP notifications from a WX switch
until you add 3WXM Services as an SNMP notification target to the
switch. (For simple configuration of 3WXM Services as an SNMP
notification target, see “Setting Up a Switch” on page 175.)
1 Click the checkbox next to SNMP to enable it, if you have not already
done so. By default, SNMP is disabled.
2 To change the minimum level of security MSS requires for SNMP, select
one of the following from the Security Level drop-down list:
„
Unsecured —SNMP message exchanges are not secure. This is the
default, and is the only value supported for SNMPv1 and SNMPv2c.
(This security level is the same as the noAuthNoPriv level described in
SNMPv3 RFCs.)
„
Authenticated —SNMP message exchanges are authenticated but
are not encrypted. (This security level is the same as the authNoPriv
level described in SNMPv3 RFCs.)
„
Encrypted —SNMP message exchanges are authenticated and
encrypted. (This security level is the same as the authPriv level
described in SNMPv3 RFCs.)
„
AuthRequest-UnsecuredNotify —SNMP message exchanges are
authenticated but are not encrypted, and notifications are neither
authenticated nor encrypted.
The only security level supported for SNMPv1 and SNMPv2c is
Unsecured.
