Configuring Dynamic Nat Pool - Cisco Nexus 3548 Configuration Manual

Configuring Dynamic NAT Pool

Configuring Dynamic NAT Pool
You can create a NAT pool by either defining the range of IP addresses in a single ip nat pool command or
by using the ip nat pool and address commands
SUMMARY STEPS
1. switch# configure terminal
2. switch(config)# feature nat
3. switch(config)# ip nat pool pool-name [startip endip] {prefix prefix-length | netmask network-mask}
4. (Optional) switch(config-ipnat-pool)# address startip endip
5. (Optional) switch(config)# no ip nat pool pool-name
DETAILED STEPS
Command or Action
Step 1 switch# configure terminal
Step 2
switch(config)# feature nat
Step 3 switch(config)# ip nat pool pool-name [startip endip]
{prefix prefix-length | netmask network-mask}
Step 4 (Optional) switch(config-ipnat-pool)# address startip endip
Step 5 (Optional) switch(config)# no ip nat pool pool-name
Example
This example shows how to create a NAT pool with a prefix length:
switch# configure terminal
switch(config)# ip nat pool pool1 30.1.1.1 30.1.1.2 prefix-length 24
switch(config)#
This example shows how to create a NAT pool with a network mask:
switch# configure terminal
switch(config)# ip nat pool pool5 20.1.1.1 20.1.1.5 netmask 255.0.255.0
switch(config)#
This example shows how to create a NAT pool and define the range of global IP addresses using the
ip nat pool and address commands:
switch# configure terminal
switch(config)# ip nat pool pool7 netmask 255.255.0.0
switch(config-ipnat-pool)# address 40.1.1.1 40.1.1.5
switch(config-ipnat-pool)#
