Questions on Metro Ethernet (ME)switches

HI,
Need some help with the following:
(1) does ME3400 support ipsla (previously known as SAA) ?
(2) Are there QoS MIBs in ME3400 that allows us to monitor the bandwidth per class just like what we usually did for router ?
Rgds
Eng Wee

12.2(35)SE, 12.2(25)SEG1 & SEG , 12.2(25)EX1 & EX These release for the ME3400 support Class-Based-QOS-MIB.
IP SLA is supported in ME3400, but has a partial support only. Please refer to this release note below for more info.

Metro Ethernet implementation questions

I am planning a Metro Ethernet upgrade for a network I manage. This is the first time I’ve implemented Metro on any network. I’m looking for some suggestions and answers to a couple questions regarding this upgrade.
The current network is Hub and spoke connected by copper lines to 17 different locations from a DS3 @ our HQ. HQ also has a DS3 to the internet which the branch locations go out for internet. At our branches we have a private and public network on different subnets. Each branch location has either a T1 or bonded T1 connected to a Cisco 2801 router then to Netgear PoE managed switch(s).
The upgrade of the DS3 for internet is going to 100 meg. The data side will also be 100meg at HQ, 10meg to our small locations and 100meg to the large.
My question is what do I need to be aware of on our existing network that must change to get this working?
1)      Will I simply go from the layer2 Metro Switch to our router?
2)      Should I remove the router and go directly to the Netgear switch?
3)      Do I need to VLAN the private and public networks?
4)      Do I need to change routing tables?
Thoughts and/or suggestions welcome.
Let me know if more information is required to assist in answers.
Thanks

Hi,
I think it would be better to include Cisco Account Manager/SE for this upgrade, they can guide you better and can come up with LLD for this upgrade, otherwise upgrading your 17 sites without proper planning can cause you serious issues.

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

Metro Ethernet Design question

Hello,
I was wondering how service providers guarantee their security protection in the Metro Ethernet model, especially when Internet is one of the applications used over the Metro network.
For example: The customer edge switch (3550) is connected directly to the service provider aggregation layer(either Cisco Catalyst 4500 and 6500 Series switches ) .
In the network core, Cisco 12000 or Cisco 7600 Series routers.
So where is the security devices in this architecture, where is the firewalls, the IDS/IPS, that protects the service provider core from any threats.
Providing the customer with Internet in Ethernet switching technology the service will put the provider in a vulnerable position.
Am I thinking wrong here?

Hi
The CE will be hardened using storm control both multicast as well as broadcast on the ports where the end users are connected.
About the accesiability between the other users who are connected on the ports of same switches you have switchport security coded which will take care of the access violation part.
Also the maximum no of MAC address which can be permitted/allowed over the ports.
This inturn will send u a trap and can shut the port if theres any violation detected on those ports..
In the next layer where u say 6500 or 7600 u will have FWSM modules which will be taking care of filtering and other funtionalities which is very much similar to a standalone PIX firewall.
you can have redundandcy or even load balancing with
the FWSM modules over there in the 6500 switches.
And ofcourse the IP addressing schemes deployed would be in private scopes and will have either NAT pools or PAT enabled in the FWSM.
you got to have more n more ACLS on all the devices to mitigate the general known worms/virus or their variants in the network applied in applicable points.

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

Basic:Metro Ethernet and DWDM vs SONET question

Hey, my understanding is that in order to deliver Metro Ethernet solutions, one system must be based on DWDM.
SONET, for example, cannot deliver Metro Ethernetsince that is based on TDM (not Ethernet, duhhh).
If the above is right, so I want to confirm that there is no other technology out there besides DWDM which can deliver Metro Ethernet services for enterprise customers?

Any number of underlying technologies can be used to deliver Metro Ethernet services - DWDM, SONET, pure play Ethernet over metro area fiber, etc.
It's more of an economic (what installed base does the carrier have or able to obtain the use of and at what cost) and efficiency (how much of the overall capacity can be feasibly broken into resellable Ethernet services without too much stranded or wasted capacity) question than a technological one. Some technologies lend themselves better to one or the other of those factors thus their dominance in certain markets.
The industry is very adept at achieving previously unthought-of solutions through the introduction of additional layers of abstraction (e., Ethernet over SONET, inverse multiplexing, etc.)

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

SONET Metro Ethernet questions

I was wondering if anyone has had a good/bad experience deploying and working with Metro Ethernet technologies since it is fairly new. I'm planning onto linking a large office 40 miles away to my central office and considered this and PPP OC3 as 2 top choices, I was told I will be able to extend my LAN without any additional hardware, anyone can share their thoughts? reliability?

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, Ethernet protection ring.

Hi everybody.
I hope everybody is doing great. A quick question for you guys.
Let say we have Ethernet switches connected in a ring .We want to use Ethernet protection ring for loop avoidance and faster convergence.
One of the switch will be RPL owner, and of the link in our ring will be chosen as RPL link.
1)My question is what is the criteria for RPL owner selection and RPL link? ( For e.g in STP, we use lowest bridge priority for root bridge)
2) Is Ethernet protection ring provide an alternative to stp when we switches connected in ring toplogy and fast convergence is required as is the case with metro ethernet commonly ?
Have a great evening.

Dear Friend
If you want to deploy and use L2 VPN service you should
define whst is he type of core
do you want to use L2 VPN service based on IP or MPLS?

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.

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

Access Connections Ethernet Location Switching only saves one port at a time

Like many other people, I cannot get automatic location switching between two Ethernet networks to work properly.
I have two stored network locations; one for home and one for work. Both of these are set up as Best Available Network with both Ethernet and Wireless.
Under Tools - Location Switching, both networks are listed, and "Include Ethernet connections in automatic switching and prompt me to save Ethernet ports" is checked. However, in the details column, the current location has 1 saved port(s), and the other has 0 saved ports. The saved port is always the one most recently connected.
If I go to Edit Saved Ports, only one location is listed, with the correct IP address and MAC address for the router. If I connect at the other location, only that location is listed, again with the correct IP address and MAC address.
The router IP addresses are different (work is 192.168.0.1, and home is 192.168.1.254), and obviously the MAC addresses are different, so it should be possible for Access Connections to distinguish them. Unfortunately the only "editing" that is possible is to delete the saved port. I would be happy to add a saved port manually, but that is not an option. In addtion, despite the "...prompt me to save Ethernet ports" being checked, I have never received a prompt. Even if I delete the saved port, it resaves automatically next time without any prompt.
I have also tried setting up both locations as Ethernet only, but have exactly the same problem.
My T520 was supplied with Access Connections 5.85 preinstalled. I tried upgrading to 5.97 in the hope that it had been fixed in the meantime. Unfortunately it has not.
Access Connections is still marginally useful to me for automatic switching between Wireless and Ethernet, and for a simple manual switch of settings such as default printer, home page, and file sharing. However, it would be very useful for the home and work locations to be autodetected and switched.
From the number of unresolved questions on this board on the same topic, it appears that this is a long standing deficiency with Access Connections. Is there any chance of this being fixed?

I found from another bulletin board that ethernet location switching seemed to work OK with Access Connections 3.82, but stopped working with releases after that, and from my experience still does not work with 5.97
http://www.thinkpads.com/forum/viewtopic.php?f=18&t=38514
Two questions:
1. Does anyone know if Access Connections 3.82 works with Windows 7?
2. If so, where could I get a copy? The oldest version on the Lenovo website appears to be 5.50
I will refrain from commenting on the necessity of going back to such an old version to recover basic functionality for this utility......

Suggest No. of routers in a single metro-ethernet Vlan

Hi,
Just would like to know if there is a recommended no. of routers to put into a single metro-ethernet vlan. The local Metro-ethernet provider suggest 10 routers per vlan but I think 30-50 would be OK ?

This question is like how many nodes can you put into a VLAN. For an answer to be given your traffic types would need to be known. How chatty are your routers? Are you bridging? What type routing / bridging traffic (non-unicase) might you have on the wire? Baseline data from your environment is important to answer this question. There is no hard fast recommendation for this just as there is none for numbers of nodes in a VLAN or router is an OSPF area. This is completely dependant on your environment.
Hope this helps,
Don
