I have a 50 Mbps metro ethernet connection between our main office, and our collocation site, where we store web servers, DR equipment and VPN access gateways. I have two Cisco 3845 ISR's connected to the metro E circuit. The interfaces on each router are configured as 100/full as requested by my ISP. We are connected via ethernet to a fiber media converter.
As I understand, CBFWQ will not kick in until congestion occurs on an interface. I also understand that the bandwidth command on an interface is to provide bandwidth related information to upper level protocols (like EIGRP, etc).
My question is that since the interface where I have CBWFQ configured on is at 100 Mbps, but my circuit is at 50Mbps, how can I get my routers to kick CBWFQ in when traffic demand exceeds 50Mbps+? Does the bandwidth command on the interface control that as well?
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 have two routers 3845 and HSRP is configured properly. Currently we are using default route to ISP and right now I want to use BGP as I have 3 Public pools and that's why I want to advertise in the public network. How I can configure that in my Router.
I have a 3845 that I am trying to configure but it won't save. It doesn't matter what i do (write mem, copy run start). No matter what, if I reload it, it wipes the config. Am I missing something, or is it just a bad memory? I don't get any errors when I save, it looks like it takes, but no dice.
we have 3845 routers with internet service providers connected on it.we have configured router bgp 2.xxx as our AS. What is the concept behind router bgp 2.xxx with ISP ?
i have two Cisco 3845 routers connected to 3 different ISPs ,
-ISP 1 with link bandwidth of 24 Mbps
-ISP 2 with link bandwidth of 16 Mbps
-ISP 3 with link bandwidth of 8 Mbps
i have a public AS from a ripe along with 2 Class Address (Public independent)
1) what is the best design and configuration to utilize the 3 Links ,outbound and inbound (since we have our public address along with AS) my boss told me,all These 3 links must be active
2)what is the recommended design and configuration for the whole topology , pls share the best gotchas
3)what is the need of iBGP?why we need it when we run bgp?
I have 3945 Router and I have bought NM-16ESW-1G1G card. After installed the card no interface shows on show ip interface brief or Show run command . When i end the switch module then i have found the interface. previously i have worked on NM-16ESW card on my 3845 router where interface card interface shows in my show run and interface command and i have assign IP and crypto map fro my Branch.
So my question is NM-16ESW-1G1G is different then NM-16ESW card ? if not then why i can not find interface. if Different then i have need to configure interfcae by enter the switch module seperately ?
Recently I came across a router (Cisco 3845, IOS 12.4) configured for TACACS, one local username and an enable password. Going through the configuration I noticed the router didn't have an enable secret password which I thought was strange. The TACACS config is below, comments regarding the TACACS config and the consequences of not having an enable secret or if there is a need for one.
aaa authentication login default group tacacs+ aaa authentication login no_tacacs enable aaa authorization exec default group tacacs+ aaa authorization commands 1 default group tacacs+ aaa authorization commands 15 default group tacacs+ aaa accounting exec default start-stop group tacacs+ aaa accounting commands 1 default start-stop group tacacs+ aaa accounting commands 15 default start-stop group tacacs+ aaa accounting network default start-stop group tacacs+
I have problems to configure CBWFQ on a ethernet sub-interface on a Cisco Router ASR 1001. Then I applied the policy in the physical interface but it should be is in the sub-interface. How can I configure CBWFQ on sub-interface in ASR 1001. (version 3.02).
Error Messages:
CBWFQ: Not supported on subinterfaces and efps
This the final output:
interface GigabitEthernet0/0/0 description Conexion WAN bandwidth 153600 no ip address load-interval 30 no negotiation auto
i have 7206VXR with trunk interface toward customers, now i'm trying to configure CBWFQ on one of the sub-interfaces for specific customer,while trying to apply parent policy which includes child policy i'm getting the following message:Must remove traffic-shape configuration first.
here is the configured policy:
ip access-list extended ACL_TEST_SRV permit ip any host 192.168.10.1 permit ip host 192.168.10.1 any ! class-map CM_TEST_SRV match access-group name ACL_TEST_SRV
I am preparing configuration (currently in lab) for Per-Tunnel QoS in DMVPN on ASR 1002F for one of our customers, and I came across one issue. According to restrictions for this feature, I cannot apply per-tunnel QoS in conjunction with interface based QoS. This means, I can provide shaping with hierarchical CBWFQ for each spoke, but I cannot guarantee anything on physical interface! What if there are services in native MPLS? I am also unable give reservations for BGP which is used on PE-CE link! How about monitoring spoke PE-CE links natively? I can only apply policy-map with class-default on physical interface. When I add anything related to queuing for that class (or any other non-default class) I get the message:
R1(config- pmap)class routing R1(config- pmap-c)#bandwidth 16 service-policy with queuing features on sessions is not allowed in conjunction with interface based
CBWFQ kicks in when the interface becomes congested and there is no available space in the queue but I need to find a solution to the scenario below:Im using a Gigabit interface on the 3945 Router that connects to the ISP. The ISP limits bandwidth to 60Mb so I need to make sure when I reach the limit of the 60Mb the router starts using the BW percentages defined in the policy-map using classes. any kind of traffic go out as it wants but as soon as the 60Mb limit is reached, the priorities defined by the traffic classes will kick in just as if the interface ran out of queues (as CBWFQ usually works).
Is there any physical or technical diferrences between PWR-3845 AC/2 and PWR-3845 AC? We are trying to order replacement parts and wondering if PWR-3845 AC is for one power supply and AC/2 means you get two with one order?

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.
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 recently ran into some problems concerning the use of a Cisco layer 3 switch (3560) as an Internet edge device to perform a simple static route between the customers network and the ISP POP router. Although this device can perform the routing at the edge for Internet traffic, I am concerned that this device has limitations when it comes to functions such as traffic shaping to the subscribed bandwidth of the Metro Ethernet access to the Internet. Since the 3560 could not conform to the 20 Mbps of subscribed bandwidth, any traffic beyond 20 Mbps was dropped causing performance issues with applications that use TCP. I am trying to find design documents or white papers that would either support or not support using a layer 3 switch as an Internet perimeter device instead of a router. I would like to know if Cisco has a specific perspective on this subject and whether or not they would ever recommend actually using a layer 3 switch model that is a 37XX or below?
I am running LMS 3.2 and can not see the Nexus 5596 / ME-3600X-24FS-M Cisco switches on Cisco works LMS 3.2. Where I need them most is DFM the devices come up as unknown. An example below 10.125.202.1 is NExus 5596 and the rest are ME3600.
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.
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 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 ?
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 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.
I have cisco 3845 on my network now its working fine.Now one of my client is asking to they want to connect their network through my router ethernet interface.
now my doubt is 3845 router will support two different gateways.
how can i route their network they have bring new router.
I have 2 x Cisco 3845 each one with a DS3 circuit, both running c3845-spservicesk9-mz.124-15.T3. In each of them I have one pvc provided by my carrier and I received the following info to configure:
We have 3845 Router which is using for only Internet connectivity with one ISP(X) Customer has only one Vlan, Public AS number, and Public IP pool.Scenario:User--> L2Access-SW--> L3 (6500) SW--> Firewall (5520) --> IPS--> 3845Router.Now we have another ASR Router, which also has Internet connectivity from another ISP(Y).Now the issue is we would like to use both ISP in active/active scenario.
I am replacing our core router, which is a very old 7204VXR, with a T3 card in it. We are using it to terminate about 10 point to point T1's. It is also the central gateway for our entire network.
I am planning on replacing it with a 3845, and an NM-1T3/E3 card for my DS3. I think I've got that part worked out.
My real question is concerning future upgrades. We are trying to convert many of these point to point connections to Metro Ethernet, and get rid of the huge DS3 cost. When that happens, I'll probably have a handful of point to point T1's left over (maybe 2-6 of them). So, what I need is a good solution to terminate those 2-6 PTP T1's in my 3845. In the past I have just been using the old WIC-1DSU-T1-V2 cards to terminate my T1's. I am looking for a solution that won't break the bank. I looked at both the HWIC-4T1/E1 and the NM-8CE1T1-PRI cards (which terminate 4 and 8 T1's), but they are like $4,500 and $8,500 respectively. That's way beyond my budget for these. I definitley don't need a card that will do PRI's (DSP's etc.). I just need it to terminate plain old point to point T1's.
So it may be that I'm just looking at the wrong cards. Or maybe the make cards that will go in the back of the 3845 that will house 2, 4 or more WIC slots, and I could just use WIC-1DSU-T1-V2 cards?
