PPPOE on Cisco 2911 Fiber Port

[bvn63]

Good day,

I have Cisco 2911 (EHWIC-1GE-SFP-CU , GLC-SX-MMD,  LC to SC Adapter. I want to configure PPPOE on cisco SFP port as diagram bellow:

Cisco R2911  (SFP Port) ---- (SC - LC Adapter) --- ISP

interface Dialer1

ip address negotiated

ip mtu 1452

ip nat outside

ip virtual-reassembly in

encapsulation ppp

ip tcp adjust-mss 1452

dialer pool 1

ppp authentication chap pap callin

ppp chap hostname XXXX

ppp chap password 0 XXXX

ppp pap sent-username XXXX password 0 XXXX

ppp ipcp dns request

interface GigabitEthernet0/0/0

no ip address

media-type sfp

pppoe enable

pppoe-client dial-pool-number 1

I had checked Dialer1 (up up ), GigabitEthernet 0/0/0 (down down), Fiber Cable (working) >>> It doesn't work

Anyone can help me how to fix this problem.

Thank you so much

Hi,

Table 1.       SFP Port Cabling Specifications

It support only MMF type of fiber. On your picture cable is SMF. Change SMF to MMF.

Hello kayukovvalera,

Thank you for helping. I had called for ISP to check what are their fiber mode using yesterday? They answered "It's Single Mode" then I had bought SMF Cable and it's not worked. If I change SMF to MMF cable as your suggest and is it worked with ISP Single mode ?

Thank you so much.
