Switch Features
Integrated DHCP Server
PowerConnect M6220, M6348, M8024, and M8024-k switches include an
integrated DHCP server that can deliver host-specific configuration
information to hosts on the network. The switch DHCP server allows you to
configure IP address pools (scopes), and when a host’s DHCP client requests
an address, the switch DHCP server automatically assigns the host an address
from the pool.
For information about configuring the DHCP server settings, see
"Configuring DHCP Server Settings" on page 883.
Management of Basic Network Information
The DHCP client on the switch allows the switch to acquire information such
as the IP address and default gateway from a network DHCP server. You can
also disable the DHCP client and configure static network information.
Other configurable network information includes a Domain Name Server
(DNS), hostname to IP address mapping, and a default domain name.
If the switch detects an IP address conflict on the management interface, it
generates a trap and sends a log message.
For information about configuring basic network information, see "Setting
the IP Address and Other Basic Network Information" on page 123.
IPv6 Management Features
PowerConnect M6220, M6348, M8024, and M8024-k switches provide IPv6
support for many standard management features including HTTP,
HTTPS/SSL, Telnet, SSH, SNMP, SNTP, TFTP, and traceroute.
Dual Software Images
PowerConnect M6220, M6348, M8024, and M8024-k switches can store up to
two software images. The dual image feature allows you to upgrade the switch
without deleting the older software image. You designate one image as the
active image and the other image as the backup image.
For information about managing the switch image, see "Managing Images
and Files" on page 333.
