CGNAT Appliance Show Commands
The RBFS CGNAT operational commands provide detailed information about the address translation operations.
NAT Pool Information
This command displays information about IPv4 address pool for a user.
Syntax:
show address-translation allocation <options>
| Option | Description |
|---|---|
pool |
Specify the pool name. |
user |
Specify the user name. |
Example for NAT pool allocation.
supervisor@rtbrick.net: cfg> show address-translation allocation pool Pool: pool1 Profile: nat_profile1 Instance: vrf1 Allocated: 100.00% Pool: pool2 Profile: nat_profile1 Instance: vrf1 Allocated: 100.00%
NAT Rule Details
Syntax:
show address-translation rule <options>
| Option | Description |
|---|---|

Without any option, the command displays the information for all rules. |
instance |
Displays NAT rule information for the specified instance. |
summary |
Displays summary of the information for the NAT rule. |
user |
