Displaying NAT information
7
DRAFT: BROCADE CONFIDENTIAL
NOTE
Three ranges are displayed in the output example. The first range from [0] to [5] refers to the MMS
port pools for NAT IPs. The second range from [0] to [5] refers to the RTSP port pools for NAT IPs. The
third range from [0] to [5] refers to the normal port pools for NAt IPs.
Displaying NAT translation
To display the currently active NAT translations, enter the show ip nat translation command.
Syntax: show ip nat translation
NOTE
You can enter the show ip nat translation command only when you use the rconsole to log into a
barrel processor (BP). The command is not supported on the main processor CPU.
[x] The variable represented by "x" represents the index of the IP address in the
IP NAT pool. For example, [0] refers to the first IP address in the IP pool
(10.1.1.10). [1] refers to the second IP address in this IP pool (10.1.1.11).
h The value following "h:" refers to the head of the port pool for the IP address
in the IP NAT pool. The head indicates the location in the port pool where the
next port will be allocated from.
t The value following "t:" refers to the tail of the port pool for the IP address in
the IP NAT pool. The tail indicates the location in the port pool where the next
port will be freed from.
T The value following "T:" refers to the total number of ports in the port pool for
that IP address in the IP NAT pool.
f The value following "f:" refers to the number of free ports in the port pool for
this IP address.
TABLE 16 Display fields for show ip nat translation
Field Description
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: When NAT is associating a TCP port with the host on the private
network.
• udp: When 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.
