Cisco WAN :: Limiting Bandwidth On Router 1800 Series

Jul 29, 2010

I will have this one router. Its f0/0 will be for the Internet connection with bandwidth of 30Mbps. Its f0/1 will be connected to a switch for internal networks. This link will be separated to 3 VLANs for 3 internal networks. I'm wondering if there is a way to gurantee 10Mbps for each VLAN but allow use up to 30Mbps when another two VLANs are not using any Internet bandwidth? I only worry about download bandwidth from internet.The 3 internal networks will all have public IPs and they belong to their own subnets. There won't be NAT/PAT.

Cisco WAN :: 1800 Series Router - QoS On FastEthernet Subinterface

Jun 28, 2011

We have 2.5 Mbps connection from an ISP at our branch routers (1800 series)with single physical link terminated on FE0 but have two subinterfaces with separate subnets.
I have applied the following policy-map outbount under physical Interface FastEthernet 0. Show poliocymap output is as follows
Policy Map QoS-OUT
   Class Email
     priority 512 (kbps)
   Class SQL
     priority 512 (kbps)
   Class File-Copy
    police cir 1024000 bc 32000
      conform-action transmit
      exceed-action drop
   Class CCTV
    police cir 384000 bc 12000
      conform-action transmit
      exceed-action drop

But it seems that sometimes( not all the time ) the CCTV traffic seems to exceed the 384k and chokes the entire link(2.5 mbps).

Cisco WAN :: Configuring QOS Between 2800 And 1800 Series Routers

Feb 20, 2012

We have an MPLS network to a half dozen remote sites.  At our main location we have a 2800 series router.  In the routers config are the following lines for QOS.  When I go to the routers on the other end of the MPLS, none of them are configured with these same policies.  Would these not be in the running config of the 1800 series routers, or is this not setup correct and this should be removed?

I have aaa new model configured on a number of isr's(1800, 1900, 2900, 3800 etc).  When i have aaa configured, the telnet logins use that authentication and not the password in the line vty portion.  Is this by design.  would disabling aaa enable both telnet and aaa authentications, essentially making it a dual login.

Cisco WAN :: 800 Series Router Basic Configuration

Sep 4, 2012

I have just bought my first non-domestic router, a CISCO 887VA-K9 which needs basic configuration to get it working.  I have a copy of the configuration guide (334 pages) and CP Express user's guide (94 pages) and have spent an hour reading but either they are missing something or my brain is too small to figure out step 1.  How to get started.  Perhaps from where to download a CP Express installation kit for Windows.
Is the only way via a terminal emulator connected via a serial port ?  Is there a graphical interface I can use ?  Are there any basic tutorials for beginners ?  This is probably the only non-domestic routrer I shall work on so I don't want to invest in a full training course.  I just need enough to plug in the ISP credentials and set up DHCP.

Cisco Switching/Routing :: Copy Startup Configuration From 877W To Another 870 Series Router?

Jan 4, 2012

I have an 877W router that I would like to have a 2nd pre-configured backup for. I was thinking of getting another 870 series (probably an 877) router, as the more expensive wireless option is not actually required. Am I right to assume that I could simply copy the contents of my current config.txt file onto the second router?

Cisco WAN :: 1700 Series Router To 2811 Series Router / Going From T1 To Ethernet?

Jan 17, 2011

I  have not done much with business routers, but we have a 1700 series  with a WAN WIC-1ENET card with a RJ45 connection. We had a T1 line and  will be moving to ehternet. We are going to be moving to a 20MB line,  and i just wanted to make sure I have the right connections before  installing. We also have a T1 line in another loaton and would be moving to this same 2811 router there as well.We  would also like to copy over the configuration from 1700 series router  to the 2811 router. Would it be easier to do it by hyper-terminal? Also if we keep the 1700 routers are they capable of using layer-3?

Cisco Switching/Routing :: How To Copy Configuration From 2900 Series To Another One

Oct 11, 2012

I know we can use copy & Paste, my questions are:

1.       Before that, do I need to wipe out the existing confi on the brand new switch?

2.       About using TFTP, how does this new switch connects to the TFTP? Does it mean I have to assign a real IP and put it on our network?

Cisco Infrastructure :: NATing With Router 1800

Oct 12, 2011

I have the following network connected and configured to a single Cisco 1800 router.

VLAN 2 (
int vlan2, ip address
 Cisco 1800 ----- int fa0, public ip address ---- Internet
int vlan3, ip address
VLAN 3 (
VLAN 2 is server vlan with a webserver.
VLAN 3 is clients.
NAT configuration:
VLAN 2 and VLAN 3 is using NAT to access the internet, and both is configured as inside interfaces.fa0 is configured as outside interface. Now I don't know if this is about NAT, but I've tried several things without luck.
A client in VLAN 3 tries to access a domain on the webserver in VLAN 2.It starts by sending a DNS query to a DNS server located at the ISP, and gets the ip address for the domain, which is of course a public ip address. Then nothing happens because the client tries to access the domain on the webserver using the public ip address, and the webserver have a local ip address which is on the local LAN (VLAN 2).
I've tried NAT because I have to change the destination ip address, but I can't seem to get it right.

Cisco WAN :: Why Does Automatic DHCP Configuration No Longer Work On 1900 Series

Jan 8, 2013

We have been using a dhcp and  tftp server to automatically configure branch WAN routers such as 1751's and 1841's for years but, have recently purchased a 1921 and 1941 as possible next generation replacements. The problem is when the 1900 series power up instead of getting a dhcp address directions to the tftp server it boots up and asks for the user name to be immediately changed or you will be "locked out".  Any workaround to this so that I can again go back to download my common configuration? Or any other way of automatically configuring the newer version ios? Doing extra steps for 500 WAN branch routers is time consuming.  Doing configurations without automation for that many is moving in the wrong direction.

Cisco WAN :: When Creating Failover Setup Cause 1800 Router To Hob Away

Mar 20, 2013

I have been given a task, where I need to create a failover setup from a 1800 Cisco router to a LAN network 2 hobs away (see topology).The reason I have been given this task is because the wireless links are not so realiably, but necessary.I'm thinking of doing this failover task with IP SLA on the routers fiber 1 and fiber 2 link, so when/if one off the links goes down, it instantly chooses the other link.I have also been thinking about implementing STP instead, and replace the router with a switch, but i'm not sure exactly how to implement it. Unfortunately I'm not able to test anything, as we are still waiting for the fiber lines, but I want to be prepared as much as possible.

Cisco WAN :: Failover On Router 1800 Having DSL And Leased Line

Feb 4, 2013

Leased line is between dammam      to dubai and the dammam office is getting internet from dubai.The ip address of Dammam      office is class A (Public IP) x.x.x.x and for dubai it is y.y.y.y which we are      using as proxy for accessing internet.I purchase the local DSL      direct line connection through cable from Local Provider and this ip address range is - it possible to use the DSL      line as failover, so if one line goes down the user should remove proxy      and can use local internet.The router which is using is      cisco 1800. 

I believe that failover is possible, 100%, but would like to know how I can do it and requesting for sharing more inputs about failover in this case.

Cisco WAN :: 1800 Router - Trunk Port L2 Switch

Feb 24, 2011

Currently I have a 4510-48g HP3COM switch as a core switch for my 4 VLAN network (which I hope to send back cause it doesn't do what I wanted it to do... PBR, which is what I need to route specific VLAN's to specific interfaces on the sonicwall,.. cause sonicwall dont understand trunk or spanning tree,. meh!) This may not happen so I've dug out an old CISCO 1800 sdsl router that has 1 FE0 port and 8 other ports, FE 1-8.
The first thing I need to do is get everything to talk to each other. So I plugged the switch into it via its configured trunk port, and configured 4 sub interfaces on the router 1800 and all seemed happy as larry and working. The problem I have is I dont seem to be able to create sub interfaces on the other ports!?

Cisco 1800 - Router Bandwidth / QOS And Rate Limit

May 21, 2012

I apologize in advance if this is a novice inquiry, but our company just switched from Point-to-Point T1's to Metro Ethernet.

On one point-to-point, from our main office to one of our high profile locations, we had two bonded T1's. Now this site has a 3 Mbps Metro-E link, but it's being over-saturated. I don't know what type of QOS implementation our T1 provider had, but it prevented flooding. Now, I'm getting horrendous latency as the office peak hours approach since there is no QOS on the mesh by our Metro-E providers.

Ultimately, my question is: what's the best way to set a Fast Ethernet port on a Cisco 1800 series router to limit all bandwidth to 3 Mbps? At the moment, I don't have a preference in which traffic takes priority. I tried the rate-limit command, along with a speed calculator I found online, but that slowed the network down immensely.

Cisco WAN :: 1800 Updating System Image Without Rebooting Router

Feb 26, 2013

I recently formatted the flash drive of an 1800 router and replaced it with an updated image. However, the new features within the new image aren't reflected in the router. I believe that this is because a reboot would be required for the updates in the new image to be reflected in the router i.e. the image needs to be added to the system. How to get the image to the system without a reboot and if by doing so I would get all the new features from the image.For example, the show version below shows the old image in the system as [code]
