Cisco Switching/Routing :: 877 Configuration For Using With 02 Broadband
Feb 13, 2013
I have been using a Cisco 877 to connect to BT broadband and it was working fantastically with no issues. For reasons outwith my control we have moved to 02 and I cannot get the cisco router to connect (the supplied router works fine). O2 support is limited as they say they will not assist in the config of third party routers but they have supplied the below (the line has a static IP). I have also included my current config which was working fine with BT. I have attempted to write in the updated info but have been unable to get the line to connect. [code]

I am position to migrate from CatOS 6509 switch to native IOS 6509 switch. long time ago, there was some site to convert automatically based on copy and paste onto the tool, but i can not find.
Does anybody know how to convert CatOS configuration to Native IOS configuration ? It is not IOS change, but it is configuration convert.

I have a good working knowledge of TCP/IP networking. I have a Cisco 3660 router I'm wanting to use in place of a WRT54G router with my Charter cable internet service. I saw a youtube video where a guy demonstrated how to use a Cisco 2600 series router with home broadband service. I followed the video to setup my 3660 router. I can ping the LAN side (192.168.1.1) with no problem, the DHCP functions as it should. I can see activity on the on the WAN port indicator but no internet access. I have attached .doc file that shows the "sho run" info. My network will be setup as follows Charter Cable Motorola Surf Modem - ethernet to MM fiber converter - MM fiber over to Sun Microsystems cabinet fiber closet - MM fiber card (on Cisco 3660 router FA6/0 WAN interface) - LAN interface FA0/0 - Cisco 3524 managed switch. One of the gigabit MM fiber ports on the Cisco 3524 feeds a 3Com Superstack 12 port gigabit fiber managed switch. My two Dell 2950 servers will be on the Superstack gigabit fiber backbone. The Cisco 3524 10/100 ports will have a Cisco access point, two IP addressible battery backup units, two Dell Desktops, and a LG Blu Ray player.

I thought I saw a post/question in regards to "how to" configure a Broadband backup for a MPLS circuit.. What I am trying to do is use a cable/dsl/ broadband (secondary) connection as a backup to a MPLS circuit (primary). I have EIGRP and BGP configured on both the branch endpoint and the tunnel headend. The tunnel is used by the interface that connects to the secondary circuit. The branch location router is a 1841 and the "headend" tunnel router is a 3825. I am wondering about the configuration/syntax of a "weight" or static route that can be used to have data flow over the tunnel when the MPLS circuit goes down - and then switch back to the MPLS circuit when it comes back on line.

I've one Cisco 3750G-12S with ip routing enable, the swtich is with IP Service firmware, with PRR support.Currently set my default static route 0.0.0.0 0.0.0.0 10.1.18.71 to my Firewall A Currently all of the VLAN for will be routed to 10.1.18.71
I've created a new VLAN 2 for my 10.1.2.0/24 network with the VLAN interface 2 ip address 10.1.2.10, my intention is to route 10.1.2.0/24 traffic to my 10.1.2.1 by creating the access list and route-map.
I've configure my test pc with a static ip and my gateway pointing to 10.1.2.10 (VLAN 2 gateway) , i'm not able to route to 10.1.2.1.

I have an broadband connection which does not need a modem to access, i get the CAT5 inthernet cable from the provider. In case if i use it directly on my PCall i have to do is provide username and password under PPPoE and internet works like a breeze.
Now i try to use this 3040 device to use as an wireless router so that i can access internet on multiple devices. How to configure this. I tried in all the three switch options provided with no result at all..I am now using a traditional router from which i connect to Tplink 3g router and using wireless under Access point option...But i would like to use it directly as i can get battery back up so that even when there is no power i can still browse?

I was recently given a PIX 501 router. I am very new to the world of Cisco, but want to learn. I got a few things setup on the router but, am not sure how to get it to use my DSL connection. My DSL modem IP is 192.168.2.1. Below is my router config. What more do I need to do? Also, is the outside IP not the IP of the DSL modem?

Any configuration example to build a vpc b/w 5ks and 7ks? i have total 4 links between them . If not, I am assuming to have the following config for the port-channels:- (Provided the vpc domain is configured).
N5k1 and 2:
int eth1/10-11
channel-group 10 mode active
switchport mode trunk
int po10
switchport mode trunk
switchport trunk allowed vlan a-d
[code]....
So, its basically vpc 10 that has 4 physical links b/w the vpc domain of 7ks and vpc domain of 5ks.

I'm currently trying to get up to speed on a 1941W ISR. I belive i have most of the configuration correct based on reading the documents on this site. However, i'm noticing that my lan to lan network performance is very slow. Peaking out about 3mbs. I was reading some documentation that suggested MGF (MultiGigabit Fabric) might resolve this problem.
I have a basic setup in my test environment trying to emulate a branch deployment. 1941W connected to a access switch (3400).
- I'm getting slow perfomance (thoughput) between the vlans 66,30,10. Will MGF fix this problem? How do i configure it?

I currently work in the IT field part-time as a end-user support technician while I am finishing my Bachelor's Degree in Network Administration. I'm not completely new to networking at this point, but I am by no means a master of it either. The basics of small networks (less than 10 PCs) and the lower-end of small business grade Cisco equipment are not unfamiliar to me. Up until this point however, I have had very little experience with any higher-end Cisco networking equipment.
Now on to the questions, which may seem like the answers should be obvious, but let's face it, I do not have the resources to own much equipment myself at this time for experimentation purposes, nor does the school I am attending have a lot of financial resources to provide us with recent hardware to learn on. What I want to know are a few things about PoE as implemented on Cisco devices, specifically the SG200-50P small business series switch. According to the technical documentation, the switch supports PoE on 24 of its 48 ports, specifically 1 - 12 and 24 - 36; simple enough. The switch is currently installed in an office that has less than 24 connected devices, but that is currently expanding. None of the PoE ports are utilized as of yet, but going forward, there will be more than 24 connected devices. Will another switch need to be installed if the additional connected devices (PCs and printers) are not using PoE, or is the PoE an auto-sensing feature that will simply remain disabled if a device that does not require power over the network cable is connected? Is there some setting that needs to be changed through the management interface to keep devices that should not be drawing power from doing so?
There will likely be some additional questions generated by my inquiry, and I fully understand if these are completely novice questions, but I admittedly do not know the answer. When I Googled it, I was greeted by a few hundred thousand results, the first dozen or so pages of results all being for places to purchase this particular type of switch, so I thought I would try my luck on the forums of the place that made it.

On a recommendation from a network engineer, I got a used Cisco 891. Having worked with small business routers most of my working life, I thought this should not be a problem. However, I had no clue these things used a console and command line to initialize. I have the console cable, am able to console into the device, but am haphazardly issuing command lines straight out of the PDF manual but cannot get Cisco CP to discover the device.
From what I can tell, I am stuck at the point where the manual tells me to enable http server. I ran the command lines several times, executed write mem where available, but when I run the show services command, http is not enabled.
And if you do refere to command lines, I was reading some other forums and they were speaking of "run this command, run that command" but I could not make out the correct syntax, in what mode, whether it be config or config t, etc. So I might need a wee bit of handholding.
I'm hoping that once I can get Cisco CP or CPE to discover the device, I can make my way through the GUI to configure since those usually do make sense to me. As of now, I'm in the thick of it ...

I am trying to configure a 891 W to basically provide DNS from my ISP to my internal clients on the 891 W. Currently when I am on a PC I can see that I receive my IP information along with the correct ISP DNS IPs. However when I try to connect or resolve a URL it fails. Nor can I perform an ns lookup from the cli of the 891 W. I seem to be having a translation issue with DNS.

I am trying to connect to the internet using the PPPoE feature of the router but the router configuration is not successful. Says something like "WAN connection not successful". I have supplied the correct username and password. The connection is ok in my laptop if i directly connect my laptop to the Ethernet port of the modem without the router. Is this a sharing problem from the ISP?

I am trying to configure Cisco SG300-52 switch for the first time and stuck without CLI configuration option. The configuration can be done using GUI, however, configuring using CLI would be more comfortable (as I am used to work with CLI of other Cisco switches)..
I was able to lo gin to switch using SSH, but the CLI appears in MENU format and was not able to find any way to go to CLI mode.
As per some blogs, in SG300 switches CLI mode can be accessed using Ctrl + Z in Menu, which did not work either in my case.
Switch is running with latest firmware version Sx300 Firmware Version 1.2.7.76.

I have a headquarters office that has recently bought a new voice system.
We have a site to site connection from the head office to 3 remote offices. All have ASA5505 firewall.
I have created 2 interface on the ASA5505: 1: inside with vlan1 and switch port port12: voice with vlan100 and switch port port2
Port1 on the asa goes to port 23 on the switch for vlan data
Port2 on the asa goes to port 24 on the switch for vlan voice
Port23 is member of vlan1 data
I added vlan100 to port 24 but by default vlan1 is member and i can't remove it. Its greyed out
All ports on the switch are member of vlan1 and vlan 100 because the port on the switch goes to the phone and from the phone there is a port that goes to the PC. Phones are getting addresses, and PC as well.
I am having a kind of loop because there is 2 exit for vlan1 (port 23 and 24) and that's slowing down my system and sometime i loose the connectivity to my servers.
When i do a show arp on my asa, i do see that some IP are beeing learned on the wrong interface. some PC addresses 192... are on the voice and some voice IP 10.10... are on the inside.
I am pretty sure that the problem comes from my switch configuration.

I have a Cisco 850 router that whas having problems getting an ip address via DHCP. I did some stuff on it but that didn't work, so I rebooted the router to go back to my last saved startup config. When I turned it back on and connected t othe CLI console I got the "Would you like to enter the initial configuration dialogue?" message. Thinikng I just forgot to save anything to the startup config I went through the initial set up again and made sure to save everything to the startup config. After going through the intial config and setting up a vlan to assign DHCP to clients I saved the config and rebooted, upon reboot and connecting to the CLI console I got the same "Would you like to enter the initial configuration dialogue?" message. Tryign the setup once more and making sure everything was saved to startup config I rebooted again just to make sure the changes would stick, and sure enough they didn't. Whay is the config not saving to the startup config?

At a college we have Ciscos 2960 and are trying to setup VLAN tagging and also using RST or MST. The traffic on the jack should get tagged vlan 248.We were told by the college that Ciscos in the labs will not work with the Alcatel switch that provides access to the lab. That Alcatel is in Bridge 1x1 mode. The college will not change the configuration on the Alcatel.We got the Ciscos to do VLAN tagging and can get network access. However the spanning- tree is not read properly. Cisco does not properly read the Alcatel's RSTP (since the Alcatel is doing tagging on the BPDUs). It places the root of the spanning tree under vlan1 instead of vlan248.
The college strongly recommends HP Procurves and we are using that as test.The following is the configuration on the HP and it works with no effort (it reads the spanning-tree information as MST)We will end up getting HPs instead, if the Cisco cannot work with the Alcatels.

try to configure QoS on a Cisco Small Business SG300 Switch. I followed the instruction on [URL] and configured one Port for tagging my Traffic from a Aastra IP Phone. Tagging works fine (i verified with wireshark).The problem is, that all traffic to a PC connected directly to the Aastra IP Phone is blocked. Is there a possibility to tag any other traffic to the port as a default?
