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?

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'm new to using Cisco Config Professional Express but a lot of things are just "off" with this utility. But my problem for this post is specifically the 891W's internal access point, or initial access to it.
My situation is that I have some 891W's. It's my first time working with them, as well as with CCP Express (2.5). After isolating the router and my PC to their own network, using the IP my PC got via DHCP frmo the router I opened a web broswer and connected to the router. The initiial configuration wizard came up and I went through the various screens. One of those screens had basic config info for the internal wireless AP which I provided. Somewhere in that screen it asked for a Hostname for the AP, and a password. It doesn't askfor a username though. To ensure I wouldn't run into confision, I made sure to set every password I ever get asked to configure as the same thing so the AP's password was also the same.
However after I finish with the wizard, the java-based CCP Express begins prompting me for first the main router credentials which I provide and it gets the router config, then it prompts mefor the username/password for the Access Point. First of all, the initial config wizard had never asked me for the username for the access point, only the hostname, and the password. I had assumed it was just going to use the main router username, or perhaps a blank username.
In any case, nothing I type ever works. I've used cisco/cisco, or a blank username with my new password, or the same username as the main router with the password ---- nothing. This is now the 4th time I have completely Reset the router to factory defaults and while I am learning the use of CCP Express through repetition, I'd also like to get this thing configured and out the door so my customer can use it.

I'm trying to set up a new ASA 5510. I have a pretty simple set up with one /24 on the inside NATed to a DHCP address on the outside. Everything on the inside works and I can ping the outside interface from external devices. No matter what I do I can't get anything internal to route across the border to the outside and back. To try and eliminate ACL issues as a possibility I added permit any any rules to the incoming access lists on the inside and outside interfaces. Here's the sh run.

I am interested in learning and setting up VPN IPSec with Cisco ASA 5505. I've managed to successfully setup VPN andcan connect to it from outside and browse securely to the outside/internet via tunnel. However, once I am connected to VPN, I cannot access any of my internal hosts/servers via VPN client. I am wondering it its a missing ACL/NAT...ASA Version 8.2(5)

I have a fresh SR520 that I only did two things to it using CCA 3.2(1):
1. Assign the address of FA4 to be 1.23.456.90 with a mask of 255.255.255.252
2. Declared a static nat of 1.23.456.90 port 80 to 192.168.75.12 port 80
I connected laptops to two ports:
1. FA0 (DHCP assigned laptop the address 192.168.75.12)
2. FA4 with the address on the laptop set to 1.23.456.90 and mask of 255.255.255.252
This is an exercise to simulate a cable internet configuration I will install the SR520 into.I can ping and point my browser to 1.23.456.89 and access the web server running there on port 80 via the inside laptop.I CANNOT point my browser to 1.23.456.90 from the outside laptop and make a connection.
What I am doing wrong with NAT? (I believe the problem lies therein as I did even try telling CCA to delete the firewall and I still could not connect to the inside web server).I have a network monitor (Wireshark) on the inside and see nothing coming across. I THINK I see successful NAT translations in the NAT logging (also in the attachment).

I am slowly working my way though the setup and configuration of our new 4900m switch. The switch will have a pretty basic operational configuration. We are simply going to network 3 servers together through the swtich. Anyhow, I have been fallowing the guide at this site: [URL]
Basically the switch is brand new and I just setup things such as the clock, the banner, and the hostname. Anyhow, at various points in the guide such as the configuration of the telnet password and especially the interface gigabitethernet I get the "invalid input detected at '^' marker". I also did a show interfaces and noticed there was not any gigabitethernet interfaces but there was a
"FastEthernet1 is down, line protocol is down Hardware is Fast Ethernet for out of band management, address i"
Anyhow, my thinking is continuing on with the guide and at least try to setup the interface for the management port so I can then use the cisco network assistant gui to then configure the rest of the switch.

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?

I have a Catalyst 3560-X PoE that suddenly stopped working. I plugged in via console and below is the output I received. It scrolls constantly and I am unable to enter ROMMON mode or stop it from scrolling. I've read of a possible problem with the IOS version but I'm unable to verify due to not being able to stop the scrolling.
Switch uptime is 4 minutes, 4 seconds

I messed up the IOS on the flash of CISCO881-SEC-K9. On reboot it booted to ROMMON which allowed me to tftp up a working IOS c880data-universalk9-mz.151-4.M3.bin. Unfortunately somewhere in my playing around the default startup configuration factory loaded on the routerhas been erased. I can load a new a config on the device but as I'm using the router to learn its useful to have the original config load when I factory reset the device. What is the factory start up config?

I have reconfigured the FEX numbers attached to a Nexus 5548 running on NXOS5.2 If I do show running-config the interfaces are not there anymore. But if I do show startup-config the old Fex interfaces still shows up. I did try write erase then saved the running-config and its still there.

I was wondering if I can force catalyst 2960 to skip startup config stored in NVRAM and boot with no config everytime it is powered. I tried to find it on google and in cisco white papers but still no luck. I found only commands that begin with "set boot config-register ... ", but switch acts like it does not know these commands.

We have recently purchased 2 x 4900M switches with the following configuration:
2 x X2-10GB-SR installed in port te1/1, 1/2 (optical)
1 x 20 x 1GB RJ45 installed in the top left of chasis ge2/1 - 2/20
1 x WS-X4908-10G-RJ45 8 port 1/2 card in the top right of chassis te3/1 - 3/8
We have te1/1 connecting the 2 switches, and various vlan's and connections on the 1GB RJ45's with no problems.
However, we have a number of 10Gbps BaseT connections te3/1 - te3/5 which are causing us issues. On a reload of the switch or removal / re-install of the cable it can take anywhere up to an hour for the port to become active again. So when we reload the switch, we may get a connection come up after say 3 mins, but the port next to it may not come up for 15-60 min. The cabling is all the same (CAT6 and has been tested/verified) and all connections go to Broadcom 10Gb cards in Dell 820 servers running vmware. We have the following set on the ports:
switchport mode access
spanning-tree portfast
No speed or duplex can be set on these ports - these options are not available in the config.
Once a link is finally established, it will hold the link solid with no problems, but this is a problem for us, we can't have a reboot take an undetermined amount of time for the link to come back.

I have a Cisco 1811 with a 4/port Serial Async/Sync (HWIC 4 A/S) and another 2 port A/S serial wic. My router seems to have a problem reading the 4/port card. I did some research and it looks like there shouldn't be a compatibility issue.

My question is wrt policy-based routing on my network. Our switch is a 3560G 24PS running Adv Ip Services image. It is connected to an 1841 and an 1811 each with a dual-wan connection . The 3560 defines 6 vlans and we are using PBR to route some vlans via the 1841 and some vlans via the 1811.
From a client on one vlan a traceroute to a client on another vlan goes through the 1811 before being routed back to the 3560. Is it possible to use PBR to detect traffic that is destined for another vlan on the same switch and then route it directly?

Recently i atsrt having problems with my cisco router 1811/k9, apparently was booting continiosly when restarted.
After i connected my console i found the problem while booting:
DDR memory test failed. Resetting the router ...
I tried to contact cisco TAC, but i need a reseller contract number to place a ticket, i do not have a resller contract number as my router was bought more than two years ago. I called cisco support and they told me to contact my reseller, my reseller told me to contact cisco so i am in a eternal loop of forwarding phone calls...

Last night I had a crack at setting up PBR on my companies Cisco 1811.Joy, I thought, it's actually working. Alas I was wrong, the addresses were getting translated to our ADSLs external ip address but routed over our EFM.What I want to acheive is to send all HTTP(s) traffic from our workstations over the ADSL (FastEthernet1) whilst all other traffic and VPN goes out over our Bonded ADSL (FastEthernet0). There is also a minor failover in place for traffic routed to the ADSL in the route-map PBR_VLAN1. The servers are on IPs 200, 202, 204 and 240.
Anyway, I have re-written the configuration and xxx'd and x.a/b/c'd all the IP addresses I want to keep secret. Need to make sure that the PBR is correct, and will do what I want it to? I have a very small time-frame to get this correct and I dont want to fudge the bucket so to speak.

I was recently tasked with adding a redundant internet connection for one of our remote sites. this new connection was to be used as the primary connection for the VPN from the site with the existing one being configured as a failover controlled by an IP SLA tracker on the new interface.
The existing connection uses a PPPoE connection configured under Dialer1 associated with FE0 to connect to our ASA. Duplicating this wasn't an option given the hardware that the second ISP provided. They provided a /29 for use; I configured FE2 using a Vlan interface with a host on that subnet.
I duplicated the connection profiles and tunnel groups on our ASA, changing only the Peer IP. Both interfaces on the 1811 are using the same crypto map.
The new connection seems fine and I can reach other hosts on its subnet from both the router and hosts on the inside of the NAT.
The issue happens when I change the default route to use the new connection.
I'm able to reach internet hosts using the new connection and I can see the VPN being established on the ASA while the VPN from the old connection drops, but I can't get traffic to route over the tunnel.
If I remove the default route that uses the new connection the VPN comes back up on the old connection just fine. There's no problem routing over the VPN when it uses that connection, just the new one.

I have an issue that started showing up since I bought a new computer. The old computer ran XP, the new one runs Windows 7. Almost every time I start the computer I get an error message telling me Windows has detected an IP conflict. Sometimes when I click okay I get the message a second timeAbout half the time, I have no internet connection when I start up and have to restart my router, which fixes the problem (after restarting the modem, I do not need to do anything like renew with ipconfig; it just starts working). I do this so often I attached it to a power switch to make it easier than unplugging.My setup is this. My PC is connected to a router connected to my cable modem. The router is also connected to a wireless hub. This hub is used by only one device, my Wii U. I can get the error message even if my Wii U is turned off.

I seem to be having an issue where certain very packets are being dropped/lost by my office router. The reproducible situation is, when I attempt a DNS zone transfer from my linux bind DNS server (A.A.A.A) to any server on my network behind NAT (Y.Y.Y.Y) the first packet (Seq 1) of the response is lost. The client making the query asks for first packet (Seq 1) to be resent, and the DNS server attempts to resend it repeatedly, but those are lost too.
