The interface is switched to Layer 3 mode.

By default, an Ethernet interface works in Layer 2 mode.

Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support switching between Layer 2 and Layer 3 modes.
Configure a hostname for the BOOTP client.
```
dhcp client hostname hostname
```
By default, no hostname is configured for a BOOTP client.

Client hostname is entered in the Option 12 field. A hostname allows access to a BOOTP client through a domain name. A domain name consists of a hostname and domain name suffix.
