Mode

Exec > ACS Configuration > Readdress Server List Configuration

Entering the above command sequence results in the following prompt:

Syntax

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
