Verifying DHCP Client on SVI
To verify the configuration of DHCP client on SVI, use the show command described below.
Router# show ip-address interface brief | include vlan15
Interface IP-Address OK Method Status Protocol
Vlan15 15.0.0.2 YES DHCP up up
Configuration Example for DHCP Client on SVI
Router(config)# interface Vlan 15
Router(config-if)# ip address dhcp
Router(config-if)# interface GigabitEthernet0/7
Router(config-if)# negotiation auto
Router(config-if)# service instance 10 ethernet
Router(config-if-srv)# encapsulation dot1q 15
Router(config-if-srv)# rewrite ingress tag pop 1 symmetric
Router(config-if-srv)# bridge-domain 15
Step 4
ip address dhcp
Example:
Router(config-if)# ip address dhcp
Specifies an IP address through DHCP.
Step 5
interface
type-number
Example:
Router(config-if)# interface GigabitEthernet0/7
Specifies an interface type number.
Step 6
service instance
instance-id
ethernet
encapsulation dotlq
vlan-id
Example:
Router(config-if)# service instance 10 ethernet
encapsulation dotlq 15
Creates a service instance on an interface and defines the
matching criteria to be used in order to map the ingress
dotlq frames to the appropriate service instance.
• instance-id—Integer that uniquely identifies a service
instance on an interface.
• vlan-id—VLAN range is between 1 to 4094. You
cannot use the same VLAN ID for more than one
domain at the same level.
Step 7
rewrite ingress tag pop [
1|2
] symmetric
Example:
Router(config-if)# rewrite ingress tag pop 1
symmetric
Specifies the encapsulation adjustment to be performed on
the frame ingress to the EFP. The symmetric keyword is
required to complete the rewrite configuration.
Step 8
bridge-domain
bridge-id
Example:
Router(config-if)# bridge-domain 15
Binds the service instance to a bridge domain instance using
an identifier.
