3750 Metro

[romccallum]

Reading the docs on the 3750 it would appear that this little switch claims to be able to do EoMPLS and L3VPNs. Has anyone tested this theory out yet? I am due to get a couple and will begin testing this device to death.

The Cisco Catalyst 3750 Metro Series includes two SFP-based ES ports. The ES ports support metro features that are vital for delivering profitable business services, such as Layers 2 and 3 and MPLS VPNs, in several bandwidths and with different SLAs. Supported features on the ES ports include EoMPLS, MPLS, MPLS VPNs, hierarchical QoS, intelligent 802.1Q tunneling (Q-in-Q), and VLAN ID translation. More details

Does that mean other ports are not MPLS aware?

Thanks

yes I know all this. What I am asking is anybody actually doing it. I will be getting some switches in a few weeks to test to death and was just wondering if anyone else has done this.

Hi,

I am going to implement this pretty soon. I need to transport some customers VLANs transparently over a SP backbone. I would prefer EoMPLS but the problem is that it's a point-to-point techno at the moment, at least on 3750 M. VPLS is not on the roadmap.QnQ would fit better. Unfortunately I cannot have feedback of such an implementation from Cisco. I'tell you what I experience.

So VLAN ID translation is not supported on Access ports?

I had done a few tests for a similar kind of configuration and had used QinQ or Vlan Stacking and it worls fine, we had tested around 2000 Vlans on this one...

Well so far I have plugged these into the lab network. Tried to do Eompls it failed (I recognise the symptons of black holing unicast packets so I know this is a bug but hey it doesnt work). I then loaded it with 4000 routes and the poor little switch died a death. Not impressed at all.

I have tested now.

QinQ: It works on the 3750 METRO although I have tested with a minimum number of VLANs. I am going to test various QoS scenarios.

EoMPLS: worked until I unplugged a link to test redundancy. Then it failed. I have an open case on this topic and will pusue testing.
