Configuring dynamic local peer IP on a PPPoE interface
1. Enter the context of the FastEthernet interface. For example:
2. Enter the following commands in the context of the interface:
no ip address
,
encapsulation pppoe
, and
ip address negotiated
.
3. Exit the context of the interface, and set the interface name as the next hop. For example:
Note:
Note:
PPP over Ethernet (PPPoE) is a client-server protocol used for carrying
PPP-encapsulated data over Ethernet frames. You can configure PPPoE on the
G250/G350’s ETH WAN Fast Ethernet port. For more information about PPPoE
on the G250/G350, see
Configuring PPPoE on page 279.
Configuring dynamic local peer IP for a DHCP Client
1. Permit DHCP packets in the ingress access control list (ACL) and the egress ACL. To do
so, perform the following:
a. Use the
no ip access-group
command to deactivate both the ingress ACL and the
egress ACL on the FastEthernet interface.
b. Add a rule to the ingress ACL and to the egress ACL, permitting DHCP packets to
pass (for information on defining ACL policy rules, see Defining rules on page 645).
c. Use the
ip access-group
command to activate the ingress ACL and the egress
ACL on the FastEthernet interface.
For example:
G350-001(config)# interface fastethernet 10/2
G350-001(config-if:FastEthernet 10/2)#
G350-001(config-if:FastEthernet 10/2)# no ip address
Done!
G350-001(config-if:FastEthernet 10/2)# encapsulation pppoe
Done!
G350-001(config-if:FastEthernet 10/2)# ip address negotiated
Done!
G350-001(config-if:FastEthernet 10/2)# exit
G350-001(config)# ip default-gateway FastEthernet 10/2
Done!
