Cisco Switching/Routing :: Upgrading A DS3 To Metro Ethernet / Gigabit Connection?
Jul 10, 2012
I have the possibility of upgrading a DS3 to Metro Ethernet, Gigabit connection. My dilemma is I have two VTP domains in my network. How can I get two VTP domains over one trunk to a remote site ?
I curently have 2 Data centers connected with a Metro Ethernet Connection. Each Data Center has 6500 with Sup720s. The Metro Ethernet connection is currently conected by a L3 routed interface. I now need to enable VRFs between the locations and want to determine the best way to adjust the Mero. I was considering adjusting the routed interface to use Ethernet sub-interfaces. Each VRF would be given a different subinterface over the Metro Ethernet connection. I have done this on internal LAN connections but am concerned about exteding across data centers over Metro E.
we are setting up our first ATT metro ethernet connection. I have a Cisco 2960S at the remote site and I placed a Cisco 2960 on the Host site to test and had no issues. When I moved the Host site to our Nexus 7000, I can not get a link.. both sides are set as trunks,
I have been reading for awhile now on all the Cisco forums on the 3560 and shaping egress traffic but I wanted to verify my thoughts on this. I have 3560 that connects to the ISP that is policing at 10Megs, I want to shape my egress traffic going to the ISP, I do not want to provided QOS to any specific traffic type but only shape all traffic outbound. Will my config below shape "all" egress traffic going to the ISP on the 3560, on a port that is physically connect at 100Meg Full duplex?
int gi0/1 srr-queue bandwidth shape 40 40 40 40
I gathered these numbers using the formula of 100* 1/weight, which would equal 2.5 and if each queue has 2.5 meg that would = 10Meg. However another concern is that I don't think I have the full 100Meg on the interface to use (correct?)
I need to connect one sw3750E with two 3750X , with Uplinks at 10 GBps. My doubt is the next:
Switch 3750E has two TwinGig Adapter Converting 10 Gigabit Ethernet X2, phisically each twinGig adapter has 2 slots for SFP modules. Can I install sfp+ If I want to use copper for Uplink at 10 Gbps, I just need to install one SFP-H10GB-CU5M transceiver ???? the other SFP slot is disabled automatically?
in the other side 3750X in order to support copper at 10 Gbps a C3KX-NM-10G network module is considered, this will be connected to SW3750E by means of SFP-H10GB-CU5M.
The second 3750X will be connected to second twinGig Adapter of 3750E using another SFP-H10GB-CU5M transceiver.
Purchased and configured 2951 router based on Telco specs that required T3/DS3 card with coax connection for MPLS. When telco showed up to install DS3 they handed me a UTP copper connection.... Can I use one of the Gigabit ethernet connections on the 2951 as my MPLS interface into the provider's cloud?
I have an Ethernet Loopback Plug (4 Pairs) made and trying to test the Gigabit Interface on a 3845 Router with a fail result. The interface will show up/up only if I set the interface to 100M/Full Duplex when I plug-in the Ethernet Loopback Plug (4 Pairs). I don't see this Gigabit Interface @ 3845 router has any option to set it to internal or external loopback.
My company uses a Sonicwall NSA 3500 as it's Firewall/WLAN controller and lightweight Sonicpoints for the private/public WIFI access. We are getting ready to implement wireless at one of our branch locations a few blocks away(We use Metro Ethernet to connect the 2).I know with the current firmware the Sonicpoints can't provision to the Sonicwall NSA over the Metro Ethernet like Cisco lightweight AP's can because the Metro Ethernet strips their VLAN Tags and obviously the Sonicpoints don't support REAP.what other options (short of installing another WLAN controller at the remote site) do I have to connect the AP's at the WLAN controller at our main location.
My new computer has a problem with the on-board gigabit ethernet it keeps dropping network connection every few minutes. Nothing has had any effect. It has been such an annoying problem, I really was hoping to find a fix for this sooner as I know other people have had similar issues. Does anyone have any other ideas because I would like to use the only ethernet connection sometime in the near future. Having to run of an WPN11 netgear usb adapter at the moment.
I have a cisco 1841 running on a 10Mbps Metro-E connection. I recently signed an agreement for a 100Mbps Metro-E. I am wondering if I will need to purchase a new router to support this new connection or will my 1841 be able to handle the traffic.
We are in the process of upgrading the bandwidth at a few offices. Each currently have a 2xT-1 connection but have high utilization on the circuit which is why they are being upgraded. We are trying to decide b/t either a partial DS3 or metro ethernet connection. Are there pros/cons b/t the two in order to decide which to go with? Cost is not an issue. Some say going with a partial DS3 circuit offers benefits over metro ethernet such as network-based failover, end-to-end availability is better with DS-3 and QoS.
my company will change WAN connection from HDSL (2Mb/2Mb) to Metro Ethernet (10Mb/10Mb). Now, I have CISCO 1841 (12.4(15)T12 ) with 2 FE and HWIC-1T. Can i configure my Metro Ethernet (WAN Connection) on one FE or i need of "external wic" such as hwic-1FE ?
I am planning on implementing a metro ethernet circuit to replace a more expensive circuit to connect my office and data center. This circuit will be configured by the provider in a 'transparent' manner, which will allow us to pass vlans freely over the circuit without having to create a QinQ tunnel. This is a layer 2 only metro ethernet circuit.Planning on connecting the office end to a 3750 (switch A) and the data center end to a 2960 (switch B). The data center end will have a couple of other 2960s hanging off of it for server connectivity (switches C & D). I plan to use a 2811 (router A)for layer 3 connectivity in the data center. Switch B will plug into router A and switches C & D will plug into switch B using two port-channelled links. I can post a diagram if needed.I will use rpvst here and configure switch B as the root bridge.There are about 10 vlans that I use between the office and data center. Router A is also used to connect to other environments such as staging, production and also to the internet. I think this should be a straight-forward configuration since it is mostly layer 2. Should switch B be the root bridge?
I am trying to configure a new metro ethernet and have some questions about the configuration. The physical layout is a main office and two remote locations. The remote sites are point-to-point connections to the main office, tagged by the ISP with VLAN 130 and VLAN 140. The connections aggregate into one handoff at the main office, and are plugged into Catalyst 3750-X switches at all three sites.
I am preparing to move two branch offices from a point to point T1 connection to Century Link Metro Ethernet.Currently my branch locations connect to my HQ 7204 router via a channelized DS3. I have a 4507R at HQ that I will connect the ME circuit to.We will also be moving our Internet connection on the ME circuit.Our service provider Clink will hand me a single Ethernet handoff for the Internet and branch office connections. For the first phase I will connect one branch office using ME. Once that is in place and tested we will move another office and so on. Then our final step is to move our web connection to the ME circuit.Each branch office has their own unique voice and data subnet. They each have a 2801 router and a 3560 switch. The routers are MGCP gateways with only one PSTN connection, a POTs 911 line on a FXO port.
So my questions are;
1 - Should I connect the ME directly in to the 3560 at the branch offices or use the Fa0/1 on the 2801? Fa0/0 is currently connected to the 3560.
2 - On my 4507R at HQ how will I configure the ME switch port? As a dot1q trunk port?
3 - Given that ME is basically a LAN connection will I have to re IP the branch office? HQ is 10.10.1.x/24. Branch is 10.10.166.x/24 (data) 192.168.166.x/24 (voice).
4 - On the 4507R will I need to configure a vlan interface for each branch subnet?
I attached two network diagrams. One represents our current topology (MEexisting) and the second represents the new ME circuit changes (MEprojected).
Today my sw upgrade procedure failed on a ME3600 Series switch.
From the past with LAN switches i thought that we need to set IP settings manually in ROMMON and then load remotely an IOS via TFTP.
But it seems that this is not supported there.So now i would like to ask how can i bring a bootable IOS to the ME3600 switch. and at least: how can i bring back my switch to life.
I could imagine that there is a missing default gateway.But what is the syntax for default gateway? And after I have connectivity i need to work for the process of loading a bootable image to the switch.
I was wondering if I could use the CISCO3945 Integrated Gigabit Ethernet WAN ports for routing, I need to enable BGP and I was willing to use one of those ports.
Have just acquired new used HP desktop running Windows Vista. System has a Broadcom NeXtreme Gigabit Ethernet card installed, which gets me to the internet OK when using a LAN cable from wireless router. But I can't make wireless connection. Vista tells me that I need a wireless network adapter.Am I missing something? Is it possible to change some settings to get the Broadcom card to go wireless? If not, what sort of adapter is needed, and is such adapter external or will it have to be installed in the system box?
I have a Linksys 10/100/1000 Gigabit NIC (m/n EG1032), which I've tried installing in my Dimension 1100/B110 without success. I followed the installation instructions from Linksys (i.e., open case and add card to motherboard, then start PC, at which point WINXP Pro should identify the new hardware and I would then select the driver from the disk. However, the "Found New Hardware" never came up. The Dimension 1100/B110 comes with an Intel Pro 100 NIC onboard. I next tried to disable the onboard NIC through the Hardware Manager, and use the Add Hardware feature in the Control Panel, but it didn't find the new NIC on the first go round. So, I installed the driver utilizing the "Have Disk" option. The Linksys NIC was installed, but stated that it might not work properly, and a look at the Hardware Manager confirmed that there was a problem (a yellow exclaimation point next the the new device and a Code/Error 10 in the Details section). The yellow light on the new NIC did flash when the ethernet cable was plugged in, but it didn't connect to the network. The Windows Troubleshooter recommended removing and restarting the PC, but the new NIC still was not found when Windows booted up. I next restarted the PC, went into the Bios and disabled the network interface. The PC took forever to restart into Windows, and still the new hardware was not recognized. I'm wondering whether there is a pin on the motherboard that I need to short, in order to be able to install a new NIC, or if there's some changes I need to make in the Windows software someplace. I've restored the Bios setting and have enabled the onboard NIC in the interim, so as to be able to access the internet and my network printer.
I am having a problem with my Realtek RTL8168D/8111D PCI-E Gigabit Ethernet NIC. It is not detecting my ethernet cable, and thus leaving me without internet on my desktop, after i updated its driver. The cable is not the problem as I have tested the cable with my laptop. I tried rolling back drivers, doing system restore and removing drivers with driversweeper and letting windows install the drivers again. However, none of these worked for me. I doubt the NIC is faulty as it was working before i updated the drivers. I am using windows 7 home premium 64-bit.
My first time programming a Cisco ASA - Anyways I''m trying to setup up Ethernet 0/6 to be a DMZ Connection When I add port 0/6 to DMZ it gives me an error saying "The IP Address X.X.X.X /Subnet Mask cannot overlap the subnet of interface outside"So my question is I have an outside connection already configured - How can I make a DMZ connection with the same subnet mask with a different IP?
The have around 80 staff and I think the current infrastructure is overkill for the size of the company. The current kit is old and they have no GB ethernet ports. They currently have:-
Core Switch: 1x Cisco c6509with a 48 port fast ethernet module (WS-X6248-RJ-45) and an 8 port fibre module (WS-X6408A-GBIC)
I'm looking to replace this with something with 72 ethernet ports and 8 fibre ports
Access Switches: 2x 3500Replacement needs at least 48 ports and 2 fibre modules each
and 2x 5500Replacement needs at least 72 ports and 2 fibre modules each.
I have 2 data centers miles apart. They are on a Paetec MPLS. I have a Lightower point to point Ethernet link between the two data centers as well. At data center A, I have a Paetec managed router (192.168.2.1). The subnets behind that router are 192.168.2.0, 192.168.100.0 and 192.168.101.0. I also have a Cisco 1841 that is configured with fa0 addressed as 192.168.2.250 and fa1 as 10.5.5.1. Fa1 is the one end of the point to point Ethernet link to data center B.At data center B, I have a Paetec managed router (10.0.2.1). The subnets behind that router are 10.0.2.0, 10.0.100.0 and 10.0.101.0. I also have a Cisco 1841 that is configured with fa0 addressed as 10.0.2.250 and fa1 as 10.5.5.2.What I want to happen is any traffic headed from data center A destined for 10.0.100.0 or 10.0.101.0 to be routed through the point to point Ethernet link. I had Paetec add routes in their managed router to route any traffic headed for 10.0.100.0 and 10.0.101.0 to my Cisco 1841 (192.168.2.250).I wanted to do the same for traffic destined for 192.168.100.0 and 192.168.101.0 from data center B. Paetec added the appropriate routes to the router at data center B.Now, if I trace from data center A to 10.0.100.45, I see this:
1 <1 ms <1 ms <1 ms 192.168.2.1 2 <1 ms <1 ms <1 ms 192.168.2.250 3 4 ms 4 ms 4 ms 10.5.5.2 4 3 ms 3 ms 3 ms 10.0.2.1
So the routing seems to be ok. However after it hits 10.0.2.1, it gets lost after that.Am I missing something? Is this a misconfiguration on Paetec’s routers?
I am in the process of upgrading our network switches and wondering if the .lic file will work with the new software or if I have to rehost for the move to 15.0. Its a remote site and I would like to get some solid info before I pull the trigger.
Also which IOS should I be upgrading to?
c3750e-ipbasek9-mz.150-2.SE.bin or c3750e-universalk9-mz.150-2.SE.bin
I am currently running a 4506 with a sup V engine. I have purchased a sup 7 engine. Is there a guide on how to perform this task. I am sure I need to do an IOS update as well.
we have two core swiches 6506 and around 55 cat 3550 switches. currently we are on the process of replacing the cat 3550 switches to 3750 switches.We need 10/1000/1000 speed, ip base image with upgrade options. Our up links from cat 3550s(sfps) are single mode and dual mode fiber mode with 1 gbps ports on core switch.
At present we are not upgrading to 10 gb modules on core. Spread over 15 floors each floor needs 2 up links(single mode , and dual mode). since cat 3750 sfps are smaller in size existing gibics cannot be used. Looking for the best option of cat 3750 switches with 1 gb up links which can be upgraded to 10 gb later when we replace the modle on core. Requirements:
1- Cat 3750 switches 55 in no with sfps for 1 gb up link (dual mode fiber and single mode fiber)
2- stacking option
3- 10/100/1000 speed
4- ip base image upgradable to ip service image
5- ipv6 compatibaility. Network is spread over 15 floors so from each floor we need two sfp up links 1 gbps using dual mode and single mode
-6-Should be upgradable to 10 gb in future when we upgrade the core modules
Or is it better to go for 10 gb module in core as well as edge switches ? if so what should be the modules?
I am upgrading a Cisco 6506E VSS from 12.2(33)SXI5 to 12.2(33)SXJ5 during a maintenance window. So I have plenty of time to reboot the VSS. Confirm below is the correct procedure. I have manually copied the new IOS to both active and standby Sup720s.
no boot system boot system flash sup-bootdisk:NEW_IOS.bin boot system flash sup-bootdisk:OLD_IOS.bin ! copy run start reload
I was going through the below cisco document and there are a few more steps as below: Is it necessary?
I am looking at upgrading my 6503-E switch. While I get the chance, I would like all aspects upgraded as I finally have some "downtime". I am running a Sup 720-3B.From what I understand, the boot image is a recovery image (mini IOS) - should the main IOS fail.Where should this be installed, sup-bootflash:/ or bootflash:/ ?,The file is “s72033-boot-mz.122-33.SXI11.bin.”The Boot Loader. My understanding is that Bootloaders are not used in these Sups with a MSFC3? I am not sure why TBH .. but would this be the case ?Rommon can be upgraded. I don’t quite understand if there are two ROMs (SP and RP).
