22 Intel® Blade Server Ethernet Switch Module IXM5414E
The switch MAC address can also be displayed using CLI command show inventory or from the
Web Interface.
In addition, you can also set an IP address for a gateway router. This becomes necessary when the
network management station and switch modules are located on different IP networks, requiring
management packets to go through a router to reach the network manager.
For security, you can specify the IP addresses of the network managers that are permitted to manage
the switch module using the config snmpcommunity ipaddr CLI command or the Web Interface
equivalent. You can also change the default SNMP community strings in the switch module and set
the access rights of these community strings.
Traps
Traps are messages that alert you of certain events that occur on the switch module. The events can
be as serious as a restart (for example, someone accidentally turned off the switch module) or less
serious, such as a port-status change. The switch module generates traps and sends them to the
network manager (trap recipient).
Trap recipients are special users of the network who are given certain rights and access to oversee
the maintenance of the network. Trap recipients will receive traps sent from the switch module; they
may then need to take certain actions to avoid future failure or breakdown of the network.
You can also specify which network managers can receive traps from the switch module by entering
a list of the IP addresses of authorized network managers. You can enter up to four trap recipient IP
addresses and four corresponding SNMP community strings.
SNMP community strings function like passwords in that the community string entered for a given
IP address must be used in the management station software, otherwise a trap will be sent.
The following are trap types that the switch module can send to a trap recipient:
Cold start This trap indicates that the switch module has been turned on and initialized such
that software settings are reconfigured and hardware systems are restarted. A cold
start is different from a factory reset in that configuration settings saved to
