3750 Metro ethernet switch

Folks,
I have 6500's at the core and want to use the 3750 at the PE. My question is the following:
1) 3750 would do Q-IN-Q.
2) Once the packet reaches the 6500(sup 720) running MPLS. What happens to the frame. Do i use xconnect to transfer the frame to the appropriate PE?
Just confussed about how does the PE use the Q-IN-Q information to direct it to the appropriate PE?
Sample config would be highly appreciated.
Thanks

3750 metro series switch does not support dot1q trunking?

Folks,
I have a 3750 metro series switch and i am trying to use it to do inter vlan routing. I do not see an option for "encapsulation dot1q" under sub interface?? why is it not supported??
Thanks

Narvin,
if you want inter-vlan routing, the interface Vlan nn itself specify vlan.I think you confuse with router subinterface where you must specify what Vlan a subinterface must use ( and encaps type ). Encaps type ( dot1q or ISL ) is used at trunk level, and whatever trunk use you can do intervlan routing using vlan interface.

What kind of Metro Ethernet Switchs?

Dear Sir,
We adopted an IP/MPLS network so we need to make expansion. The expansion will be Cisco Metro Ethernet Switches.
What kind of Cisco Switch will be suitable for this purpose ?
Find the attached image for the Network topology so the Core routers is Huawei NE80E and the Edge Router is Huawei NE40E.
Waiting for your suggestion.
Regards.

Hu Hussein!
I worked a lot on ME3750..I can´t recommend this platform! The hardware and sw features are obsolete.
If you do not need MPLS, the ME3400E (E Series!!) supports features like "selective QinQ", wich could be very nice n an metro ethernet network.
http://www.cisco.com/en/US/docs/switches/metro/me3400e/software/release/12.2_58_se/configuration/guide/swtunnel.html
You have only 1GE ports.
I think the ME3600X/3800X should be the choice. You have the features like 3400E and EVC support
http://www.cisco.com/en/US/docs/switches/metro/me3600x_3800x/software/release/12.2_52_ey/configuration/guide/swevc.html
The 3600X by default has enabled the two 10GE ports. The 3800X NO. Check the licensing model (also for scalabiliz, mpls) before you buy...
The features of the platforms are nearly the same.
The 3800X supports larger TCAM, more VRFs,ecc
I never used the 3600/3800 series.The platform is very new. But future proof
..or maybe a 6500 or 7600 platform (if you need port density)...?

Thomas

Metro Ethernet Switches Network Implementations

I wish that Cisco would collect as many as network scenarios and pratical configurations for 3750ME, Metro Ethernet, and MPLS, starting with few basic one.
Cut down the marketing materials. It will benefits all customers and cut down supports.

There are lot of such materials.

Metro ethernet switches

i am new at metro ethernet. What is needed in a standard switch (Cat4500, Cat6500, etc) in order to support metroethernet services. thanks ahead
asanes

Hi,
It basically depends where you want to put the devices you stated in the network, looking at the devices I think you should have MPLS, LDP/RSVP and other standard routing protocol.
For access, you also should have STP (RSTP/MSTP) configured.
Please go through this link for further information

Netflow on Cisco Catalyst 3750 Metro Series Switches

Does netflow possible in 3750 metro series?

Hi Syed,
You have to first check if there is any image in switch or not so that you can manually boot from switch: prompt but as you said there is no image in the switch you have to go for xmodem procedure to upgrade the switch.
Have a look at this link and just follow step by step instructions and you will be good to go

Use of Metro ethernet switches

Folks,
I have looking at a sample config for EWS. The senario has 3550's at the enge and 6500 at the core. 6500's were doing the Q-IN-Q functionaility to carry customer vlan over provider vlan.
My question is where would a 3750 series metro switch be useful. Lets say i had a 7600 P.E which also have Q-IN-Q functionility, why would i buy a 3750 if i was a provider?
Thanks

Hello,
simplified one driving factor for Q-in-Q is port cost. The cost of an ethernet port on a 7600 is higher than the same port on a 3750. So for a SP serving many customers and potentially in need of hundreds of ethernet customer ports, it means that the hardware invest will be lower and therefore competitiveness in the market will be better.
Hope this helps! Please rate all posts.

As Peter wrote, Metro Ethernet is a vast topic. However, from a non-provider perspective, the idea is to allow interconnecting widely physically separated (your) site networks just about as simply and similar to connecting your LAN together at one of your sites. I.e. you just connect different (your) site devices with an Ethernet connection, and you use that connection pretty much like you would any other Ethernet link between your devices.
From a carrier or MAN provider perspective, running a widely distributed, multiple customer Metro Ethernet (or a carrier Ethernet) network, you'll want some features not found in (as you say) "normal" Ethernet equipment.
What's different about Metro Ethernet switches is they generally offer features not found in "normal" Ethernet switches. Again, from a non-provider perspective, you often only need/desire a few additional features (and for that reason, it's not uncommon for non-providers to use "normal" Ethernet switches with Metro E - I've also seen Metro E switches used with "ordinary" LAN Ethernet networks). From a provider's (carrier's) perceptive, you'll really want more features. Because of these two perspectives, you'll often find Metro Ethernet switches marketed to non-providers, and Carrier Grade Ethernet switches marketed to the MAN Ethernet providers.

3750 Metro series do not dot1q trunking??

Folks,

Thanks

Navin,
The 3750 Metro series switch does not support Layer 3 trunks; you cannot configure subinterfaces or use the encapsulation keyword on Layer 3 interfaces. The switch does support Layer 2 trunks and Layer 3 VLAN interfaces, which provide equivalent capabilities.
For more information, see the note under Table 12-5 on this page: http://www.cisco.com/en/US/products/hw/switches/ps5532/products_configuration_guide_chapter09186a00803960dc.html#wp1326724.

EoMPLS with Catalyst 3750 Metro Switches

Hi,
I am trying to setup an EoMPLS tunnel (VLAN mode) between two 3750 Metro switches. But I am not getting the Status down from the both PEs.Also the 'show mpls l2transport binding' shows no output interface and no label stack is attached. Can anybody in the forum help me out? Is it any IOS related problem.
The IOS version is:c3750me-i5k91-mz.122-25.SEG1.bin
Thank you,

Hi,
can you provide the related config? Without this it is hard to tell anything.

URGENT: MPLS P/ PE support on 7600/Sup720-BXL and 3750 Metro switch

I'm need to design a MPLS network for a Cable Operator.
They will start small with some Cisco CMTS doing MPLS-PE and needing only two devices to aggregate these PE and delivering Services (Internet connection, VoD, ...) , so they will need to work has P/PE.
For that I want to know if it's possible to:
1 - Use 3750 Metro and 7600/Sup720-BXL as P and PE
2 - Who many customers (L2VPN/VLANs and/or L3VPN/VRF) can they support?
Searching in CCO I found these values/features but, need URGENT to check:
1 - sup720-bxl supports P and PE but 3750 only PE?
2 - 3750 supports 1024 VLANs and 8,192 MPLS labels but no values on L3VPN/VRF?
SUP720 supports more than 1000 VRF?
Really need urgent HELP on this design/capabilities for these two devices.
Thanks in advance,
MP
Network Consultant - CCIE

before you even get anywhere close to the numbers of L2/L3 on a 7200 I would seriously consider asking what throughput you can get through a 7200 with MPLS, QOS, L3vpns and L2vpns configured. I have done this testing already but dont think it is appropriate to quote the figures publically.

Metro Ethernet Design With Redundant Head Ends

We're getting ready to turn up some metro ethernet circuits that were just installed by AT&T. AT&T has provided a VLAN for each remote site (so each site has its own VLAN), and those VLANs are trunked to our head end switches (Cisco 3750 Metro Switches).
I'm struggling with the best design for IP routing. We currently use OSPF on our internal network, and I was going to extend OSPF to our metro solution as well, but I'm not so sure now.
I don't want routing to occur directly between head end #1 and head end #2, we already have redundant paths within our corporate network, and allowing our two head ends to route between each other via our metro ethernet solution is not what we want. However, running OSPF on each of the VLANs which have been provisioned for us would permit routing between the head ends.
We simply need to allow redundanny for our remote locations in the event that one head end were to fail, all of the traffic to/from the remote site would be routed through the head end which is still online.
Anyone suggestions on the best routing design for this situation would be greatly appreciated. I've attached a network diagram to make things clear. I believe I can also go back to AT&T and request one VLAN that includes all sites if that would simply things. I just need to make sure I can still do our traffic shaping because the remote sites are only 10mbps and the head ends are 1gbps.
Thanks,
-Steve

just at a glance it looks as if you should be able to have stp on and setup 1 site as primary and other as secondary

Comparison between 3750 and 3750-metro

hi folks,
is there any links which will provide me on the comparison between 3750 and 3750-metro? for exapmple, isis is not support on 3750 but it support on 3750-metro. The product information from cisco site is insufficient in term of the main differences :p

The metro switches have the PXF chips (which allow hierarchical QoS on the 2 "WAN" GigE ports, so several logical links can share a connection, and have soft bandwidth limits).

Comcast Metro Ethernet Setup

We have one customer with one ASA and one 3750 switch in headquater. 6 1801 Routers in 6 branches.
All connected via MPLS/BGP provided by ATT. And it was terminated at one port on 3750.
We plan to replace that with Metro Ethernet Hub/Spoke topology since the customer mentioned each office never talks to each other. Later on we found they have IP phones do need to talk with each other at branches.
Question - can we still use the MetroE service but configure routing to make each office talk with each other and how that would work?? I would assume some routings on 3750.
Any info is appreciated. thanks!
Ben

Hi Ben,
It will work for sure since this is what ( in a much more complex scenario) we are implementing in our company since ab few months. Just take care of defining data and voice subnets as technically unrelated so to be free implementing very flexible and easy to manage routing policies. Is ATT providing L3VPN or what?
Hope to help
