Parameters
slot slot-number: Specifies a card by its slot number. If you do not specify any card, this command
displays EIM entry information for all cards. (MSR4000.)
Usage guidelines
A NAT device with PAT EIM configured does the following:
• First creates a NAT session entry.
• Then creates an EIM entry for recording the mapping between an internal address/port and a NAT
address/port.
The EIM entry ensures the following:
• The same mapping applies to subsequent connections originating from the same source IP and port
as the first connection.
• Allow reverse translation for connections originating from the external to the NAT address and port
based on the EIM entry.
