page and click Save to save your corrected information. You must
configure at least one community to enable this SNMP agent.
7. In the Community Name field, enter a name or authentication string to specify
the community.
8. In the corresponding Host Name or IP Address field, enter the host name or
IP addresses of each community manager.
9. If a DNS server is not available on your network, scroll to the bottom of the
page and click Save.
10. If a DNS server is available on your network, scroll to the Domain Name
System (DNS) section. A window similar to the one in the following illustration
opens.
11. If a DNS server (or servers) is available on your network, select Enabled in
the DNS field. The DNS field specifies whether you use a DNS server on your
network to translate host names into IP addresses.
12. If you enabled DNS, in the DNS server IP address fields, you can specify the
IP addresses of up to three DNS servers on your network. Each IP address
should contain integers from 0 through 255, separated by periods.
Notes:
a. Enter an IP address in the IP Address field and its corresponding host
name in the Host Name field. You can define four mappings. You need to
do this only if a quick lookup of a host name is required.
Use the fields in the Host Name section to define relationships between an
IP address and its corresponding host name in the event that your network
DNS server is unreachable. You can also use these mappings for
frequently used host names.
b. The Remote Supervisor Adapter uses this table when first searching for an
address to host name mapping. If a match is not found, the data will be
requested from the DNS server. If the table contains an entry for a given
address, the host name defined in the table will override any corresponding
entry defined on the DNS server.
