4.7.2.User Name and Passwords

This switch can also be accessed via a direct connection to the console port or through
a network connection using Telnet or a Web browser. When managing the switch by any
of these means, a user name and password is required to enter the system. The factory
defaults include two sets of user names and passwords. One set has administrator
rights, which allows you to view or modify system parameters. The other set has
read-only access, which allows you to view the status of the system, but not to modify it.

4.7.3.MAC Address Filters

If you discover that some nodes are sending abnormal or destructive data that could
adversely affect the network or cause security problems, you can set their MAC
addresses to be filtered by the switch. Any packets with a source or destination address
listed in the MAC address filter will then be dropped by the switch upon entry.

4.7.4.IP Address Filters

IP addresses can also be set to be filtered by the switch. IP packets with a source or
destination address listed in the IP address filter will be dropped by the switch upon
entry.
4.8.SNMP Management Software
SNMP (Simple Network Management Protocol) is a communication protocol designed
specifically for managing devices or other elements on a network. Network equipment
commonly managed with SNMP includes hubs, switches, bridges, routers and host
computers. SNMP is typically used to configure these devices for proper operation in a
network environment, as well as to monitor them to evaluate performance and detect
potential problems.
4.9.Remote Monitoring (RMON)
Remote Monitoring provides a cost-effective way to monitor large networks by placing
embedded or external probes on distributed network equipment (hubs, switches or
routers).RMON has already become a valuable tool for network managers faced with a
quickly changing network landscape that contains dozens to hundreds of separate
segments. RMON is the only way to retain control of the network and analyze
applications running at multi-megabit speeds. It provides the tools you need to
implement either reactive or proactive policies that can keep your network running
based on real-time access to key statistical information.
This switch provides support for mini-RMON which contains the four key groups
