default consecutive-failures
default
Configures this command
with its default setting.
Default: 5
consecutive_failures
Specifies the consecutive
number of times a server can be unreachable after which the system
marks the server as inactive.
consecutive_failures must
be an integer from 1 through 10.
Important: If not explicitly configured,
the default value of 5 will be used.
Usage Guidelines

of a previously inactive server is rechecked.
Example
The following command
configures the reactivation time to 180 seconds:reactivation-time 180
response-timeout
This command
allows you to configure the time duration for which the system will
wait for a response from the server before marking it unreachable.

server_list_name
Entering the above
command sequence results in the following prompt:
[local]host_name(config-readdress-server-list)#
Syntax
Syntax Description
server [ ipv4_address | ipv6_address ] [ port port_number ]
no server [ ipv4_address | ipv6_address ]
no
If previously configured,
disables the specified server configuration.
ipv4_address | ipv6_address
Specifies the IP address
of the DNS server.
ipv4_address must
be expressed in IPv4 dotted-decimal notation format.
ipv6_address must
be expressed in IPv6 colon-separated-hexadecimal notation.
port port_number
Specifies the TCP
port of the DNS server.
port_number must
be an integer from 1 through 65535.
Usage Guidelines
Use this command to
configure the DNS server(s) to which the flow will be readdressed based
on the contents of the Fully Qualified Domain Name (FQDN).
Example
The following commands
configure the DNS servers for packet flow to 192.168.12.101, 192.168.12.102, and 2607:f0d0:1002:51::4/64:server 192.168.12.101
server 192.168.12.102
server 2607:f0d0:1002:51::4/64
The following command
removes the DNS server configuration for 192.168.12.101 that
was configured above:no server 192.168.12.101
