Installation guide

Overview 1-17
Multiple IP addresses for a single VLAN allow the configuration of multiple IP addresses, each belonging to
different subnet. Class configuration allows a DHCP client to obtain an address from the first pool to which
the class is assigned. For more information, see Configuring the DHCP User Class on page 5-19.
1.2.3.3 DDNS
Dynamic DNS (DDNS) keeps a domain name linked to a changing IP address. Typically, when a user connects
to a network, the user’s ISP assigns it an unused IP address from a pool of IP addresses. This address is only
valid for a short period. Dynamically assigning IP addresses increases the pool of assignable IP addresses.
DNS maintains a database to map a given name to an IP address used for communication on the Internet.
The dynamic assignment of IP addresses makes it necessary to update the DNS database to reflect the
current IP address for a given name. Dynamic DNS updates the DNS database to reflect the correct mapping
of a given name to an IP address.
1.2.3.4 VLAN Enhancements
The switch has incorporated the following VLAN enhancements:
• Network interfaces operate in either trunk or access modes.
• A network interface in access mode can only send and receive untagged packets.
• A trunk port can now receive both tagged and untagged packets. Each ethernet port is assigned a native
VLAN.
• You can now configure a set of allowed VLANs on a trunk port. Packets received on this port that belong
to other VLANs are discarded.
1.2.3.5 Interface Management
The switch’s physical interfaces auto-negotiate speed and duplex. The switch also allows:
• Manual bandwidth configuration of a physical interface speed to 10/100/1000Mbps.
• Manual duplex configuration of a physical interface to Full Duplex or Half Duplex.
• Manual configuration of administrative shutdown of a physical interface.
1.2.4 Management Features
The switch supports the following management features:
• A secure, browser-based management console
•A Command Line Interface (CLI) accessible via the serial port or through Telnet or a Secure Shell (SSH)
application
• A CLI Service mode enabling the capture of system status information that can be sent to Motorola
personnel for use in problem resolution
• The support for Simple Network Management Protocol (SNMP) version 3 as well as SNMP version 2
• Upload and download of Access Port firmware and configuration files using TFTP, FTP, SFTP and HTTP.
• Transfer of firmware and configuration files using Compact Flash (RFS7000 only) or USB (RFS6000 and
RFS7000 platforms only)
• The graphing of wireless statistics
• A GUI dashboard summary of system status
• Multi switch management via MSP application
