44 BES50 advanced features configuration
as the Element Manager. You can specify up to five management stations
to receive authentication failure messages and other notification messages
from the switch.
By default, the switch issues notifications as trap messages. The recipient
of a trap message does not send a response to the switch. Therefore,
traps are not reliable as inform messages, which include a request for
acknowledgement of receipt. Informs can be used to ensure that the host
receives critical information. However, inform messages consume more
system resources because they must be kept in memory until a response is
received. Inform messages also add to network traffic.
If you specify an SNMP version 3 host, then the Trap Manager Community
String is interpreted as an SNMP user name. If you use SNMP version 3
authentication or encryption options (authNoPriv or authPriv), you must
first define the user name in the SNMP version 3 Users page to enable
password authentication and SNMP access to the switch. However, if
you specify a SNMP version 3 host with the no authentication (noAuth)
option, an SNMP user account is automatically generated, and the switch
authorizes SNMP access for the host.
