The DHCP client is enabled by default. You can disable or re-enable DHCP client on a switch or a router.

On a switch, enter global configuration mode.
```
switch# configure terminal
```

Enter the no ip dhcp-client enable command to disable the DHCP client.
```
switch(config)# no ip dhcp-client enable
```

Enter the ip dhcp-client enable command to re-enable the DHCP client.
```
switch(config)# ip dhcp-client enable
```

On a router, enter the ip dhcp-client disable command to disable the DHCP client service on all physical interface and virtual interface level.
```
router(config)# ip dhcp-client disable
```

Enter the no ip dhcp-client disable command to re-enable the DHCP client service on all physical interface and virtual interface level.
```
router(config)# no ip dhcp-client disable
```

Enter interface configuration mode.
```
router(config)# interface ethernet 2/1/1
```

Enter the no ip dhcp-client enable command to disable the DHCP client.
```
router(config-if-e1000-2/1/1)# no ip dhcp-client enable 
```

Enter the ip dhcp-client enable command at the interface configuration level to re-enable the DHCP client.
```
router(config-if-e1000-2/1/1)# ip dhcp-client enable
```

Enter the ip dhcp-client enable command at the virtual interface level to re-enable the DHCP client.
```
router(config-if-ve1)# ip dhcp-client enable
```

The DHCP client is enabled by default. The following example disables the DHCP client for a switch.

switch# configure terminal
switch(config)# no ip dhcp-client enable
switch(config)# ip dhcp-client enable

The following example re-enables the DHCP client for a switch if it has been disabled.

switch# configure terminal
switch(config)# ip dhcp-client enable

The following example disables the DHCP client service on all physical interface and virtual interface levels for a router.

router# configure terminal
router(config)# ip dhcp-client disable

The following example re-enables the DHCP client service on all physical interface and virtual interface level for a router.
