IP Configuration
This chapter describes the Address Resolution Protocol (ARP) and Domain Name
System (DNS) client features.
It includes the following topics:
•
ARP Table
•
Domain Name System
ARP Table
The switch maintains an Address Resolution Protocol (ARP) Table. Each entry in
the table includes the IP address and the MAC addresses of a device that has
recently communicated with the switch.
You can use the
ARP
page to display ARP entries learned by the management
VLAN. To display this page, click
IP Configuration
>
ARP
in the navigation window.
You can click
Clear ARP
to delete all entries from the table, except for the
management port IP address and MAC address.
Domain Name System
The switch supports IPv4 DNS client functionality. When enabled as a DNS client,
the switch provides a hostname lookup service to other applications on the switch
such as ping, RADIUS, syslog, Auto Configuration, and TFTP. The switch can be
configured with DNS servers that resolve hostnames to IP addresses. The switch
can also be configured with static host-name-to-IP-address mappings that bypass
the DNS server.
See the following topics for more information on the configuration pages available
in the IP Configuration > Domain Name System menu.
