IP Addresses and SNMP Community Names

Each switch must be assigned its own IP Address, which is used for communication with an SNMP
network manager or other TCP/IP application (for example BOOTP, TFTP). The switch's default IP
address is 10.90.90.90. You can change the default switch IP Address to meet the specification of your
networking address scheme.
The switch is also assigned a unique MAC address by the factory. This MAC address cannot be
changed, and can be found when using the command "show switch."
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 from 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 allow you to
manage the switch. You can also change the default SNMP Community Strings in the switch and set
the access rights of these Community Strings. In addition, a VLAN may be designated as a Management
VLAN.

Setting an IP Address

The IP address for the switch must be set before it can be managed with the Web-based manager. The
switch IP address may be automatically set using BOOTP or DHCP protocols, in which case the actual
address assigned to the switch must be known.
The IP address may alternatively be set using the Command Line Interface (CLI) over the
console serial port as follows:
1. Starting at the command line prompt local>, enter the commands config ipif System
ipaddress xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy. Where the x's represent the IP address to be
assigned to the IP interface named System and the y's represent the corresponding subnet
mask.
2. Alternatively,
xxx.xxx.xxx.xxx/z. Where the x's represent the IP address to be assigned to the IP
interface named System and the z represents the corresponding number of subnets in
CIDR notation.
Using this method, the switch can be assigned an IP address and subnet mask that can then be used
to connect a management station to the switch's Web-based management agent.

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 recipient).
Trap recipients are special users of the network who are given certain rights and access in overseeing
the maintenance of the network. Trap recipients will receive traps sent from the switch; they must
immediately take certain actions to avoid future failure or breakdown of the network.
