Metro ethernet configuration

Months agao I had a 10MB metro ethernet link installed between two of my locations within 3 miles of each other. The link is fiber with a conversion module to copper, 10MB ethernet.
I have the link on one end coming into a fastether port on a cisco 2620 router and the other end on a fastether cisco 3745.
My routing the man like a frame link, each location is on a seperate subnet.
I have not configured either end for IPsec, tunnel, etc.
I have had the line checked by the ISP, but constantly received interface resets,output errors and excessive collisons.
I feel I'm missing something from the configuration.
I have verified my equipment is fine, both fastethers have been changed so my equipment is good.
Any suggestions would be appreciated.

It is related to send a busty traffic to you Ethernet interface and check the duplex and speed for both ends (It should be match).Check any viruses updated from the local Computers. Normally collision will happen when an Ethernet or transceiver cable is too long or when there are more than two repeaters between stations. So if the error is more then automatically the interface is resets. I hope the below link provide you more information.

Hi,
Kindly let me know " How to enable alerts for metro ethernet link"
Thanks..

Hello Gureshi,
they are probably referring to OAM, CFM and other mechanisms to detect link or service failure in metro ethernet scenarios

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

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.

Hello Gurus,
I would like to know a bit more about this tecnologie (Metro Ethernet over Docsis).
I work for a cable companie and we would like to know the implicationd of implementing such a technologie.
If we go for a CPE based aproach we only have to configure a CPE like the Cisco 1805 in each costumer end-point?
Which configurations does the CMTS and backbone require?
What are the maximum speed we can offer with this technologie running on HFC?
Any help would be much appreciated.

Metro Ethernet newbie needs help

Need to configure new 15 site Metro Ethernet network with this physical topology:
x=x=x=x=x=x=x=x
|oooooooooooooo|
X====X-X==x==X
|oooooooooooooo|
x======x======x
x=7604, X=7606
= 2x 10Gb Ethernet
- 2x 1Gb Ethernet
This network will provide metro ethernet services to several customers, but for now we only have one ME-3400G-2CS switch on each site.
I've been reading about Metro Ethernet and MPLS technology for a few days now and I still don't have any clue how I'm going to put all this working together. Can anyone help me?

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

Metro Ethernet 3550 IOS

Hello,
Just a basic question:
Is there an recommended IOS version for a Cat 3550 acting as a U-PE in a Metro Ethernet implementation?
Thanks!

The Catalyst 3550 will now provide limited support for Policy Based Routing (PBR), while Catalyst 3550 Metro Ethernet users can benefit from Layer 2 Tunneling Protocol enhancements, which allow configuration of drop and shut-down thresholds based on ingress packet rates.

Building metro ethernet using cat3750

Hi,
I am Mazlan and work for one of ISP in Malaysia. We would like to discover metro ethernet technologies.
We would like to use our current backbone network to create this metro network and we are planning to use cat3750.
The design is something like this.
R1--cat3750--RA--[WAN}--RB--cat3750--R2
R1 and R2 is in different location but will be running on same VLAN (with help of cat3750). Let say there is customer connected to R1 and their branch at R2, they will only feel they are in same LAN, but actly they are in different location.
We need some opinion of builidng this network. I need help for the configuration in cat3750 as well in the router. We have no experince in this technologies.
Perhaps somebody whos is interested to help me out can email me at [email protected]
Your help is highly appriciated.
--mazlan

The Catalyst 3750 switch supports IEEE 802.1Q tunneling and Layer 2 protocol tunneling.

Bellsouth Metro Ethernet -- is it QinQ?

I have a customer who has bought some connections from Bellsouth's Metro Ethernet product. I am having a tough time getting someone at Bellsouth to give me any information about the product.
Are they just using QinQ (802.1q tunneling) to make it all happen? If that's the case then I should just trunk to them with 802.1q and not have to do anything else, I believe keeping the native vlan 1 should even be fine. If anyone knows anything about this or has connected sites using the Bellsouth metro-e product please let me know.
Brian

Hello,
looks like it is Ethernet over SONET, with a possibility to migrate it to EoMPLS:
"Currently BellSouth uses a specialty Ethernet switch to support its shared multipoint offering, but that may change. "We're converting to more of a general purpose device that will be part of our MPLS network and will deliver Ethernet and other services," hints Kaish.
Some carriers have implemented shared multipoint services directly over fiber, which means that those services do not include Sonet restoration capability, effectively limiting them to non-critical traffic. But BellSouth's metro Ethernet network is Sonet-based and customers can leverage Sonet's restoration capabilities, Kaish says."
http://www.findarticles.com/p/articles/mi_m0DUJ/is_13_107/ai_108408900
Another source of information supporting the statements above:
http://newsroom.cisco.com/dlls/2004/prod_070604.html
In any case this does not mean straight forward, that you can use the service to setup trunks between your switches. This depends on the interface configuration of (presumably) the 7600. They might restrict you to dot1Q with one VLAN or even to plain ethernet.
Hope this helps! Please rate all posts.
Regards, Martin
P.S.: have a look at http://www.metroethernetforum.org/presentations/SC2003_BobSmithEntNet.PDF which should answer many questions! Especially they state "Dedicated Ethernet supports VLAN tagging" - sounds like setting up a dot1Q trunk with them will be supported.

Is Metro-ethernet Secured ? Compare with FR/ATM

Hi,
Just would like to understand if Metro-ethernet has the same security level as FR and ATM ? Metro-ethernet has broadcast nature and it seems mirroring ethernet frame is much more easier than FR and ATM . Is there any study onto the security issues presented in the Metro-ethernet technology ?
I see a lot of customers doing IPSec on the Metro-ethernet and they don't do this on the FR or ATM links ?
Thanks

I have not seen any document, but my understanding is that FR and ATM networks do not have broadcast capability which is an inherent security feature. Sites can communicte only if a VC is configured between them. In metro ethernet, broadcasting is possible and the providers have to implement security to islolate customers by configuring some feature. Since the customers may not trust the level of security provided by the providers, they may choose to run IPSec over this type of access.

Integrating Metro Ethernet to DSLAM

Dear friends,
I am very new to Metro Ethernet and currently I am facing a solution problem. The thing is my customer want to deploy a MEtro Ethernet Network, which in turn they should be able to interconnect to a DSLAM network. The specific customer requirements are below, i am getting smoke out of my ears working on this.
1) Deploy a Metro ethernet network and integrate it to DSLAM network
2) Design should be such that customers of my customer (SP) can change his bandwidth limitations. For eg: if the SP's customer wants to have a video conferencing for a few hours then say for some 4 hrs he/she should be able to change the provided bandwidth. The SP should be able to monitor and bill for this.
3) As a section of this Metro Ethernet solution a part should be able to provide video,data,voice and other near future application on EXISTING RJ 11 telephone wire connection at the customer places.
I have only 1.5 yrs experience in networking and that too only on configuring and installing routers,RAS FW switches etc. I have never been to Solution providing and this is the first one. I dont want to lose it. can any one help ???
Pleeeeeeeeease !!!!!!!!!!!!

Hi,
Your requirment seems to be preety simple as far as metro ethernet deployment is concerned.
Suggest you to look for Cisco Service Selection Gateway ( SSG ) feature set on Cisco 72xx,73xx,10K series routers. With SSG coupled with SESM , users have flexibilty of change the bandwidth on the fly and SP can bill him accordingly.
Apart from the requirement of bandwidth change , i would like to make a point that your customer should go for ADSL 2 or 2 + for catering triple play services ( voice,video and data )
As far as metro e network is concerned i would have gig ethernet bandwidth in the backhaul .
If the customer is not so Cisco Savvy , you can look for Juniper SDX platform , which supports COPS !!! ;)
you can reach me a [email protected] for any assitance required .

Help with setting up Metro Ethernet

Can someone please help and give suggestions and possible configuration options for setting up metro ethernet in the following senario:
Will be setting up ME between headquarters and three remote branch offices. Each remote branch will be provisioned to 10MB, and the headquarters will have one link for the aggregate provisioned to 30MB.
My questions, we will have routers at the remotes, but how will this terminate at the headquarters? Do we connect the one ME aggregate connection to a router, or to a L3 switch? And how do you configure the headquarters devices to separate the traffic? Do you use sub interfaces like in frame relay? Please provide a sample config if possible.
Thanks

HI,
Assume you have 3560 SW at your HQ and where you can terminate the ME circuts.
Configuration in Switch as:
3560SW#sh run int Fa0/5
Building configuration...
Current configuration : 123 bytes
interface FastEthernet0/5
description ***************
switchport access vlan 40
switchport mode access
end
Create a SVI interface at the Router, the configuration is as:
7604-Backbone-RTR#sh run int Vl40
Building configuration...
Current configuration : 119 bytes
interface Vlan40
description *********
ip vrf forwarding 1234-NAME-MESH
ip address xx.xx.xx.xx 255.255.255.252
end
In the above configuration, VRF is applied on Interface to make the pefix unique across the Backbone.
is it here at the remotes where I will configure the "sub-interfaces"?
A. Yes, the case for remote is same as that of HQ.
Pls Rate if HELPS
Best Regards,
Guru Prasad R.

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
