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).
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.
I understand that the NM-1FE Fastethernet modules are not compatible with Cisco 2600 series routers, just the Ethernet 1-E module. With that being said, are there ANY modules supported by the 2600, 2621 or 2621XM series routers that have fastethernet port(s) outside of the pricey NM-16ESW module? I don't need a 16 port module!
I am trying to install a AIR-BR1310G wireless link between two buildings. I configured the setup in a lab and had everything functioning. Shipped it to the client who is now trying to install it. The radio link is up, but we are having issues with the remote Ethernet connection.The root bridge is connected to a WS-C3560G-24TS (core) switch. The port is setup as a trunk with a native vlan of 2 (our management vlan). [code] if I do a "show power-injector" on the remote radio (no Ethernet link), I get: "Received zero AutoMIB packet from Power Injector, Check to see if CDP is disabled on Fast ethernet" repeating. No other entries. If I do the same command on a unit with a link (root bridge) I get information about "Power Injector Port 0 speed 100Mb/s duplex full link up enabled yes" with a bunch of stats. Similar for "Power Injector Port 1". Power Injector Ports 2-4 as "down" and 5-6 as "disabled". Other than the 3 different patch cables they tried (all straight through) or a crossed cable (try tomorrow when they buy one), is there any other reason the port won't go Up/Up?
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 a task of setting up bandwidth limit on the 2811 router Fastethernet interfaces.The scenario is:We have a 4MB Internet connection and would like to allocate bandwidth usage to users.
Fastethernet 0/0 needs to be set with 256KB output and 2048 input. This is going to be connected to a wireless router. Fastethernet 0/1 needs to be configured with 2048 output.I could also use SDM if that's easier than using CLI.
why I can't use cisco ehwic-3g-hspa-u card in cisco 2800 series and 1841 series router?documentation said that it should work with that devices but when I installed it, it doesn't work even as device i can't see I am using cisco latest ios advance ent. 15.1(4)M4?
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?
I have an existing 1800 router that is using NAT and VPN to HQ. I now have a new ISP provider and so now i need to chane the Fastethernet1 IP address. I know how to do that but what else do I need to change to make everything continue to work?
I don't know much about routers, but lately I've been playing around with router configuration and getting better but I am kind of stuck now.
The scenario is this.
I have 3 ip net from the ISP: 178.249.51.0/255.255.255.248 Gateway 178.249.51.1 178.249.51.8/255.255.255.248 Gateway 178.249.51.9 178.249.51.16/255.255.255.248 Gateway 178.249.51.17
[Code]....
I am also wondering - when we get more public IP net from the ISP, is this the correct way to do it?
I'm troubleshooting an issue with a new site-to-site vpn setup between 1800 series routers. The tunnel is up but not encrypting traffic on one router, when IP CEF is disabled traffic is encrypted and decrypted!
I have the following network connected and configured to a single Cisco 1800 router.
VLAN 2 (10.1.20.0/24) | int vlan2, ip address 10.1.20.1 | Cisco 1800 ----- int fa0, public ip address ---- Internet | int vlan3, ip address 10.1.30.1 | VLAN 3 (10.1.30.0/24)
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.
Problem: 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 10.1.20.20 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.
I am having the most difficult time trying to setup the Cisco 1841 with a new Fiber Optic ISP. I have no experience with Cisco equipment but have taught myself some basics. All my attempts have ended with failure. I definitely will be taking some cisco courses soon.
Our current setup
20mbs Fiber Optic ISP
- They are providing us a x.x.129.233/30 WAN IP and a x.x.131.225/27 Public IP Block Cisco 1841 Router (Which has no configuration at all, it was wiped by the ISP) 1x HP Procruve 2610 24 port Gigabit Switch
What we need is simple, we just need to distribute the Public IP block through to the LAN on the switch side. I would post a config if I had one already made, but the 1841 is a clean slate. I just wiped it again to start fresh.
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.
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 192.168.1.0 - 192.168.1.254.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.
I have configured PBR on my 1800 series router, it is working perfect. Now I am changing my router from 1800 to 2901 router with the same config, so the PBR stop working and I am not getting hits in the second WAN interface. [code]
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!?
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.
We're seeing a strange issue with a Cisco 819 that we're testing out. We are able to ping out over the Cellular interface just fine, but as soon as we plug a device into one of the FastEthernet ports we immediately drop the cell connection. The Cell interface then continues to bounce until we unplug the device. We are intending to setup a VPN tunnel, but we've even stripped all that out for the sake of troubleshooting.
I am new user of cisco router i can access the hardware and login in the account but the problem is if i use the command "enable" asking for a password, old I.T. personnel who setup this router already resign.
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]
I have strange problem with 1800 router , I can't see any debug messaging , the ping from PC to this router is Ok , but no icmp debug appears , even I enable "debug ip icmp " the version of router is : C181X Software (C181X-ADVENTERPRISEK9-M), Version 12.4(6)T6
I have a SR520 router with the ADSL WAN built in. I am looking to ignore the ADSL port and utilise the 4 FA ports to route between two networks.Can I configure the ports on the switch part of the router to become Layer 3 and take there own Ip addresses? If so I can save myself the purchase of a new router.I have used loopbacks before but not sure that will work.
I am getting the new Cisco 2921/K9 router, which comes by default with 3 Integrated 10/100/1000 Ethernet ports. I have Comcast Cable as the ISP, so can I connect the ISP RJ45 Copper cable directly to one of the integrated ports or do I have to buy another WAN Interface Cards for the ISP.
