DHCP Client
An Aggregator is auto-congured to operate as a DHCP client. The DHCP client functionality is enabled only on the default VLAN
and the management interface.
A DHCP client is a network device that requests an IP address and conguration parameters from a DHCP server. On an Aggregator,
the DHCP client functionality is implemented as follows:
• The public out-of-band management (OOB) interface and default VLAN 1 are congured, by default, as a DHCP client to acquire
a dynamic IP address from a DHCP server.
You can override the DHCP-assigned address on the OOB management interface by manually conguring an IP address using
the CLI or CMC interface. If no user-congured IP address exists for the OOB interface exists and if the OOB IP address is not in
the startup conguration, the Aggregator will automatically obtain it using DHCP.
