IP Configuration
Configuring Domain Name System
STEP 1
Cisco 220 Series Smart Plus Switches Administration Guide Release 1.0.0.x
Viewing Static and Dynamic DNS Servers
The search list contains one static domain name defined by the user on the DNS
Settings page and dynamic domain names received from DHCPv4 and DHCPv6
servers.
To view the domain names that have been configured on the switch, click IP
Configuration > Domain Name System > Search List.
The following fields are displayed for each DNS server configured on the switch:
•
Source—Source of the server's IP address (static or DHCPv4 or DHCPv6)
for this domain.
•
Preference—Order in which the domains are used (from low to high). This
effectively determines the order in which unqualified names are completed
during DNS queries.
•
Domain Name—Name of domain that can be used on the switch.
Configuring Host Mapping
Host name and IP address mappings are stored in the Host Mapping Table (DNS
cache).
This cache contains the static entries that are mapping pairs that were manually
added to the cache. There can be up to 128 static entries.
Name resolution always begins by checking static entries, and continues by
sending requests to the external DNS server.
Eight IP addresses are supported per DNS server per host name.
To add a host mapping:
Click IP Configuration > Domain Name System > Host Mapping.
The Host Mapping Table displays the following fields:
•
Host Name—User-defined host name or fully-qualified name.
•
IP Address—The host IP address.
•
IP Version—IP version of the host IP address.
•
Type—Static entry to the cache.
