To set the IP address of the IPv6 default gateway for the network to which the
switch belongs, type “ipv6 default-gateway
gateway ,” where “gateway” is the
IPv6 address of the default gateway. Press <Enter>.

Dynamic Configuration
Obtaining an IPv4 Address
If you select the “bootp” or “dhcp” option, the system will immediately start
broadcasting service requests. IP will be enabled but will not function until a
BOOTP or DHCP reply has been received. Requests are broadcast every few minutes
using exponential backoff until IP configuration information is obtained from a
BOOTP or DHCP server. BOOTP and DHCP values can include the IP address, subnet
mask, and default gateway. If the DHCP/BOOTP server is slow to respond, you may
need to use the “ip dhcp restart client” command to re-start broadcasting service
requests.
Note that the “ip dhcp restart client” command can also be used to start
broadcasting service requests for all VLANs configured to obtain address
assignments through BOOTP or DHCP. It may be necessary to use this command
when DHCP is configured on a VLAN, and the member ports which were previously
shut down are now enabled.
If the “bootp” or “dhcp” option is saved to the startup-config file (step 6), then the
switch will start broadcasting service requests as soon as it is powered on.
