Issue with cisco ONS 15310. Slot with Ethernet ports, designed for bridging.

[vanessa-white]

Hi, guys. I’ve got an issue with cisco ONS 15310 sdh optical network. I’ve got a special slot with Ethernet ports, designed for bridging. Assume, we’ve got to multiplexers, named A and B with ports A0 and B0 respectively. The ios console of these slots says, the configuration is as follows:

no ip address set on these ports

Ports are administratively up

Auto mdix

Bridge groups are the same on these ports.

Dot1q tunnel.

I’m trying to monitor a device with an ip-address connected to port B0. It answers ping if I connect the notebook directly to a device. But if I connect the notebook to port A0 and ping the device pluged in port B0 through the optical network, it doesn’t answer. I tried connections with straight and cross cable.

Guys, who set the network said, it should work as a point to point bridge with no extra configuration. But it doesn’t. I used wireshark sniffer to lookup what’s happening on port A0. All I see is cdp-s from port A0 and self-announcements of the notebook.

Any suggestions? Thank you in advance.

I'm assuming you are using ML-100T-8 cards - correct?

It sounds like you might possibly have an issue with the VLAN or dot1q tunneling setup. Have you had a look at the configuration guides for the card (here)?

Can you possibly post the IOS configuration from the ML-100T-8 cards at each end?

Can’t access the page.

Can you possibly post the IOS configuration from the ML-100T-8 cards at each end?

Yes.

I use interfaces FastEthernet1 on both sides.

Today I tried "no mode dot1q-tunnel" on these interfaces. Didn't help.

[Marvin Rhoads]

Sorry about the bad link - you should be able to use this customer link for the ML-100T-8 card:

http://www.cisco.com/en/US/customer/docs/optical/15000r9_1/ethernet/310/guide/31091_ether.html

Hmmm. I was going to suggest what you already tried - "no mode dot1q tunnel".

Having that mode on means the Ethernet interfaces on the ML-100T-8 are expecting your traffic to enter with VLAN tags. Please have a look at this guide:

http://www.cisco.com/en/US/docs/routers/7600/ios/12.2SR/configuration/guide/dot1qtnl.html

(The link is for a 7600 router guide but the concepts are applicable to IOS in general.)

You should make sure that you are tagging your traffic towards the ONS at both ends (that is, you are set up as a trunk port and using dot1q encapsulation: "switchport mode trunk" and "switchport trunk encapsulation dot1q" commands on your switches at each end) and that you are forcing the port towards the ONS to be in spanning tree forwarding mode ("spanning-tree portfast trunk" command).

[vanessa-white]

Your advices were very very very very helpful! It looks more clear now.

Thanks! Thanks for helping me, I really appreciate such a support.

[Marvin Rhoads]

You're welcome.

Please rate posts if they help.
