26 Switch Management Concepts
IP Addresses and SNMP
Community Names
Each Switch has its own IP Address, which is used for
communication with an SNMP network manager or other
TCP/IP application (for example BOOTP, TFTP). You can
change the default Switch IP Address to meet the
specification of your networking address scheme.
In addition, you can also set an IP Address for a gateway
router. This becomes necessary when the network
management station is located on a different IP network as
the Switch, making it necessary for management packets
to go through a router to reach the network manager, and
vice-versa.
For security , you can set in the Switch a list of IP
Addresses of the network managers that you allow to
manage the Switch. You can also change the default
Community Name in the Switch and set access rights of
these Community Names.
Traps
Traps are messages that alert you of events that occur on
the Switch. The events can be as serious as a reboot
(someone accidentally turned
OFF
the Switch), or less
serious like a port status change. The Switch generates
traps and sends them to the network manager (trap
managers). The following lists the types of events that can
take place on the Switch.
