switch(config-if)# ip address dhcp
Displays the IPv4 or IPv6 address assigned to the interface
in the running configuration.
(Optional) Do one of the following options:
Step 5
•
show running-config interface ethernet slot
/
port
•
show running-config interface mgmt 0
•
show running-config interface vlan vlan-id
Example:
switch(config-if)# show running-config interface
vlan 3
Copies the running configuration to the startup
