Cisco 877 Won't Bring Up VPN
Sep 29, 2011
Im trying to setup a site to site VPN using a Cisco 877, problem is we have no ADSL presentation, we've just been given an Ethernet line to use from another client in the building, If i plug my laptop into the port and use the External IP information given i can use the internet and ping the other VPN just fine, if i place my blank config 877 into the port and set up VLAN 10 to use the same IP information, it cant even ping the local gateway? The port on the router is in VLAN 10 like it should be and the interfaces are all up, the router can ping its local VLAN 10 ip address.

I've attached my ASA's config. I can't bring the VPN up by pinging from the ASA but the VPN will come up when someone pings from behind the ISA server. So the problem seems to be routing/NAT on my ASA because my pings aren't being directed out the tunnel. The VPN in question has 64.106.x.x as the peer and AES 256/SHA for phase 1 and 2.

I have 2 ASR 1006 with ASR-1000-ESP40, ASR-1000-SIP40, ASR-1000-RP2 , and with SPA-1X10GE-L-V2 that should hold an XFP-10G-MM-SR.
i am in the proceed of an implementation and configuration, but i am facing a problem on the interfaces, where i am not able to bring the interfaces up/up and always down/down.
i check the fiber patch cords and the other SFP on the switch WS-C3560E-12D and it is working fine. i also reverse the fibers pins and nothing works
i need only to get the interface to be up/up. i also checked all the hardware compatibility matrix, IOS XE, the SPA are all online (show platforms).... where all seems to be ok and compatible.
all what is needed is to give the interface ,for example, tengig0/0/0 and ip address and no shut and it should go up/up.
One more thing, the XFP is not giving a red light laser, and in the show interface tengig0/0/0 give media type is unknown.

I know I can bring up a tunnel up-and-up without any layer 3 address, without any ipv4 or ipv6 address (apart from tunnel source/destination of course). And I don't have to use "ip unnumbered <interface>" either. But what good is a tunnel interface with no address? Can you bridge them or something?

I am trying to configure an IPSEC tunnel on a 1921 router. What I hope to accomplish is that using a IP SLA that the IPSEC tunnel will only be brought up IF the normal WAN connection is not responding. My thoughts were to route the traffic that needed to come back to corporate through a loopback interface but I havent found a way to do that.

I'm trying to bring up two t1 and bundle them into a multilink on a 3845 on one end and a 3725 on the other end. On the 3845 I have installed two VWIC-2MFT-T1-DI and on the 3725 I have installed two VWIC-2MFT-T1 and a 1DSU/CSU-T1-V2.
For some reason I'm able to bring up the T1's on the DSU/CSU WIC. When I try to connect the T1 on the other WICs, on the 3845 I see SLIPs and Interface Resets however on the 3725 there is no errors however I still see UP DOWN.
CONFIG 3845
controller T1 2/0/0

How do I get one of these to automatically bring up the VPN tunnel without the end user having to login and click connect? I got the VPN working Dynamic to ASA static, but it doesnt come up on its own when I try to access something over VPN.

I've to bring vlan 2 access to a remote site through 2 AP1261N configured as bridges. Here it is the network diagram
One AP1261N is configured as root bridge. Its ethernet interface is connected to a switch with vlan 1 native and vlan 2 tagged. Vlan 1 is for APs and switches management. Vlan 2 is for users access. The other AP1261N is configured as non-root bridge and one PC is directly connected to the AP's ethernet interface. I've successfully managed to create i wireless link between the 2 APs and so I can reach the vlan 1 IP address of the non-root AP. My problem is that I can't reach the PC connected to the non-root AP.
Here are the conf of the 2 APs:
root AP
version 15.2
no service pad

I have 2 4402 WLC running 7.x.x.x code. I also have some 1510 Mesh- L WAPs that require an old version of code. I need 4.1.192.22M for those. Is it possible to bring up a 3rd controller running this old code with the other 2 4402's running modern code? What will break? I know that anchoring and mobility might get messed up. What are the other caveats?

I'm using a Dell computer CPU i7 8 gig of ram. It is wired in to the router. Why does it take so long to log into the router and bring up the different pages in the settings. I have never seen a router take so long. I have not updated the firmware version 2.02NA. I have not upgraded it yet. oh I have a cable connection. When I surf the web the pages come-up fast.

I am trying to connect a 6509 switch to a 4503-E switch using single mode dark fiber over a distance of less than half a mile. Although a routine task, it does not work..We have a care 6509 switch where we concentrate all of our dark fiber connections for our remote sites. The 6509 switch already has 30 remote sites, most of them with 4503-E switches, connected in this way therefore it is a tested scenario. For the connections we use the GLC-LH-SM SFPs on both switches. Out of these 30 sites we had a similar problem with two of them, which we solved with the use of CWDM SFPs. With the CWDMs the fiber came up right away. However, I cannot keep using this solution because it is way too expensive! I had the losses of the fiber measured end-to-end and they are negligible (>0.5 dB).
In this latest case, like I said, we could not bring the connection up between the core 6509 switch and the 4503-E switch using the GLC-LH-SM SFPs. I then replaced the 4503-E switch with a 3560 and the link came up! Then I tried using a CWDM-SFP in the 4503-E, while keeping the GLC-LH-SM SFP in the 6509 and the link came alive again! Of course we already tried replacing the fiber patch cords with no luck. [code] I find it very weird for the link to work with the 3560 or with a CWDM in the 4503 but NOT with the SFP in the 4503!

I have two 3825's. Each has it's own ISP connection. Nat is configued for both. They have an ethernet connection between them and I'm running OSPF between the two so the routes propogate. I have qty 11 Dialer interfaces configured on each router (each router has an exact copy of the other routers dialer interface). However, I only want the Dialers up if the ISP connection on the mated router goes down. Much like HSRP I need one to preempt and be active if both ISP connections are up. When one goes down the other Dialers must come up. Each dialer sends a Dynamic DNS host name and IP address pair to DynDNS.org. So I cannot have both up otherwise the DNS names will bounce between ISP#1's IP address and ISP#2's IP address (back and forth). Let me know if any option exists to make this happen. As an aside the ISP's are providing me DHCP addresses so I cannot work off of an IP, it has to be the physical interface (i.e. Gi0/0).

I need WIFI inside a giant steel Quanset hut. There is a good signal right outside. Is there a way to do this with one device? I was wondering if I could put one of the antennas of a WRT54G through a hole to the outside and then set it in repeater mode. Theory being it would use the outside antenna to pickup the signal and the inside antenna to broadcast.

Will this router ever see a firmware update so that we can have some additional functionality? The version of Twonky Media server that was bundled with this router was old to begin with, and now we are stuck with it? I tried the E4200 but it just kept spinning my drive that's parked in a ThermalTake BlackX, at least the 3000 doesn't do that, but when can we expect some new firmware, it's been 8 months. I used to love Linksys, but with this kind of support I may have to move to a different brand, and I bet I am not alone. it doesn't break the E3000 like you broke the 4200.

I installed this Linksys E1500 yesterday and have had a problem keeping my iPhone 4 and an iPod Touch connected to WiFi.The devices go to sleep. When I swipe the screen and "bring them back" the WiFi is Not Connected. I have to go in and re-enter my network password again. As long as the devices don't go to sleep, they maintain connectivity. Once connected they function properly.
The iPad 2 & Samsung Galaxy S phone we have seem to be keeping their WiFi connectivity, as well as a G62 HP laptop running Windows 7, an older XP machine using a Cisco AE1000 wireless network adaptor and the Xbox 360. The issue is just with the iPhone 4(ios 5) and the iPod Touch(ios 4).
I had issues with the iPad and the Galaxy phone until i disabled WMM Support in App & Gaming.I would bring this back to the retailer but I had it sitting on my desk for about 30 days and it's past their return policy.The firmware is up to date on the Router. I've tried power cycling all the devices including the cable modem & the new router.

I'm trying to test fast roaming using a Cisco 2100 Series controller and 2 1140 APs. The initial authentication succeeds fine and the wireless connection works ok using WPA2+CCKM and LEAP with a Cisco ACS radius server.The problem is that the client does not attempt to preauthenticate with the other AP because the RSN Capabilities IE in the AP beacons and probe responses do not set the RSN Preauthentication capable bit. I can't figure out what it takes to get the APs to indicate to clients that it can do preauthentication. I'm been crawling through all the documentation I can find, to no avail.

We are about to share a 10 MBit ISP connection with 2 others companies, and they are going to split the bill up into 3,3 and 4 Mbit, so we where thinking that we could setup a switch before their and ours router and provide them with a static IP from our ISP. But is it possible to set a bandwidth limit on the ports of a Cisco Catalyst 2960-8TC, so that we can set a limit of 3,3 and 4 on 3 ports.

I currently use a device called the Access Enforcer which runs OpenBSD. I have 3 stable, working VPN tunnel's where the other side's device is a Cisco ASA 5520 or 5540. I was setting up my 4th VPN where the other side used a Cisco ASA 5520 and ran into issue's. The Cisco side can bring up the tunnel. Once the tunnel is up each side can talk to the other side. However, when the tunnel is dropped, the OpenBSD side cannot bring up the tunnel. The error received is on the OpenBSD device is "isakmpd[29581]: transport_send_messages: giving up on exchange from-XX.X.X.0/24-to-XX.XXX.XXX.240, no response from peer XX.XX.XXX.141:4500". I have been trying to figure this out for weeks now and can't seem to find the cause.

I am trying to configure a 3750G that has been sitting on the shelf for several months and am getting the following error -
% Error: Unable to create flash:/microcode_update% Error: It must not already exist
Normally, getting an error during POST isnt a good thing. My first thought was that flash was corrupted or flagged RO somehow. I did fsck flash: with no change. I next tried fsck /test flash:. It tested 77 blocks and performed 0 erasures. It had been running for about 15 minutes with no problems reported so far. Multiple reboots of the switch still report the same error.
I have reviewed the history of what I have done on this switch and finally think I found the problem. I noticed a microcode_update directory that I am not used to see on a 3750. Deleted the directory using the rmdir command and rebooted the switch. On reboot, I noticed that a front_end/ directory was listed as being created as well as fe_type_1 and fe_type_2 were created. The switch now boots up without any errors.

I have two Cisco Aironets 1401 connected to a Cisco Catalyst 3560 Switch. When users log onto the Wifi the APs authenticate with a Freeradius that then authenticates with LDAP.
Recently users have been getting kicked off of the network but I'm not sure why.If so how do I set these APs to roam with my setupd?For all I know there could be an issue with the switch I'm just not sure where to start when it comes to troubleshooting this issue.

Guys I am using a cisco 2911 router with three interfaces: Gi0/0 connected through a switch to all my servers and Gi0/2 which will connect to another server, and Gi0/1 is my outside interface connecting through a switch to two ISP's.I have webservers and Terminal servers/File Servers with 10.0.0.0 network address connected throught My Gi0/0 interface.Now I want to implement a Cisco Advanced firewall for security on my router using CCP.I want the firewall to work such that it allows external users to access the servers on Gi0/0 through ports 0,23,25,20,21,53, 110,3389. and to access the SIP server on Gi0/2. My issue is can i just create two DMZ's for both interface Gi0/0 and Gi0/2 without creating an inside zone and Gi0/1 as outside zone as my internal traffic is mostly server based and the users connect remotely through terminal server to access resourcess using RDP, secondly how do I open the relevant ports.I have checked alot and all I have seen is just basic process on using the wizard I have no idea how to go about this issue.

I am struggling to have my PPTP traffic to get routed through NAT to reach other Server LAN segment. I am using Cisco 2921 router as a PPTP server.This Cisco 2921 router is working as PPTP server and doing NAT also to reach Server LAN segment (LAN-B).My problem is after PPTP connection establishes I cannot reach any of the LAN segment, but after connecting PPTP I can browse Internet without any issue, but none of the LAN element is reachable. Please have a look on the configuration I am posting 2921 router configuration to suggest something, I have also attached the network setup for better understanding…Just to update Clients in LAN-A can access Internet as well as servers (LAN-B).
