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
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
