Displaying NAT redundancy information
You can display information about the state of the static NAT IP or NAT pool (dynamic), the MAC
address used, and the configured priority. The MAC address used for the NAT IP is a special
construct, where the last 3 bytes of the MAC address are derived from the shared NAT IP address
(similar to the symmetric MAC).
To display NAT redundancy information, enter the following command.
The two “Priority” options are “High” and “Low”. That is, 2 or 1.
The two “State” options are “Active” and “standby”.
TABLE 8 Display fields for show ip nat translation
This field... Displays...
Pro When PAT is enabled, this field indicates the protocol NAT is using to uniquely
identify the host. NAT can map the same IP address to multiple hosts and use
the protocol port to distinguish among the hosts. This field can have one of the
following values:
•tcp – In addition to this IP address, NAT is associating a TCP port with the
host on the private network.
•udp – In addition to this IP address, NAT is associating a UDP port with the
host on the private network.
Inside global The Internet address mapped to the private address listed in the Inside local
field for inside NAT.
Inside local The private address mapped to the Internet private address listed in the Inside
global field for inside NAT.
Outside global The destination of the traffic. If PAT is enabled, the TCP or UDP port also is
shown.
NOTE: Outside NAT is not supported.
Outside local The destination of the traffic. If PAT is enabled, the TCP or UDP port also is
shown.
NOTE: Outside NAT is not supported.
