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?

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?

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 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]

Cisco Routers :: How Does Quality And Longevity Of SRP500 Series Compare To RV Series

May 27, 2012

My Draytek 2710 just dies after 2 years so I was looking for something a little more reliable and noticed the spec of the SRP527W-U.I take it with only one antenna and reading a couple of past discussions, the wireless will only manage n-lite as some people call it i.e. 150Mbps, and not the full 300? Oh, and are the ports still only 100M and not Gig?I know the 547 would tick both these boxes but we are talking twice the price.  How does the quality and logevity of the SRP500 series compare to the RV series (which would need an adsl modem) or the Linksys boxes?

Now organization proposal is:
- Use MPLS and use an extranet network. Advertise a certain unique route to each partner..
- Grant unique VPN ID for each partner and VRF Lite at the data center. Then bring each partner with separate tagged VLAN to the data center via MPLS.
Can VRF Lite scale to more than 300+ partners OK?

Cisco WAN :: 3 NAT Addresses On 1800 Firewall

Oct 15, 2012

I have a client that has 6 public  IP addresses.  He needs to use 3 of them.  One for workstations which is  currently working fine.  It is using the default gateway IP.  One for a  email/web server which has a statis NAT and is also working fine.  But  we need an additional NAT but it is for 3 servers that all need to go  out as the smae public IP.  I am not sure and been unsuccessful getting  those to go out as the same IP.  I either cannot get them to exit the  same IP or it breaks the workstation NAT.
Workstations would be - 200 going oput the FE1 interface or I think x.x.94.122
Email would be going out the statis NAT of x.x.94.123
I then need - 4 to go out x.x.94.124
I removed some ACLs and IP info for security. Attached is the current config.
interface FastEthernet0
description $ETH-WAN$$FW_OUTSIDE$
ip address x.x.4.240
