Help with connection to fiber optic!

[asemyc2013]

Hi all, I need replace the old configuration for the new configuration (see attached photos). The old configuration works perfect but when I put the new I haven't internet connection, Light indicators interfaces indicate that traffic is OK and all is working good(green lights blinking):

Question : Need the Cisco 2960S-24TS-L any special configuration to handle the traffic of the optical fiber to the LAN?

Please someone can help me with this.

Regards,

Asem.

Asem,

If your ISP has a filter on their end, it will need to be updated to allow your switch's interface gi1/0/28 mac address.

That address - which they will have to enter at their end  - is as shown in one of your earlier post's attachments:

show int GigabitEthernet1/0/28

GigabitEthernet1/0/28 is up, line protocol is up (connected)

  Hardware is Gigabit Ethernet, address is 0c27.243f.4b9c

Probably they block the port once an unknown mac is seen.

Power on the edge-core, connect to it with a laptop and check what mac would be seen on that port. Then set it onto gi1/0/28

Otherwise, you could get rid of the switch sending its own data into the port (its mac will never be seen in transit packets, only on frames generated by the switch itself, so there's a bunch of supplementary protocols to disable):

int gi1/0/28

spanning-tree bpdufilter enable

no cdp enable

no lldp transmit

no vtp

switchport noneg

Last, but not least: you shouldn't have an int vlan in the same vlan that's used on gi1/0/28 (vlan1 in this case). Configure the uplink to your router as trunk and select another vlan for management.

Thanks again friends, I can't negotiate with the ISP, they just want money and any change involves changing my contract.... (My boss doesn't want to spend more money)

I can't connect to the Edge-Core with a laptop because they left only a one port enabled (goes to my LAN router), even if I unplug my LAN Router and put your IP data in my laptop I can't connect to internet.

Finally, I will have to stay with the old Edge-Core at 100Mb/s, with the new Cisco hanging off the rack and the pain of having lost $200 in an SFP module that will not use.

Here I send the output of the latest changes, now I put the port 24 and 28 in the same VLAN 85:
