View 7 RepliesI have a 2620 Cisco Router plugged into a 2924 Cisco switch by a trunk.The vlan configuration works, I subdivide my router interface with dot1q and have virtual machines on different vlans and everything works perfectly.The problem comes with a DHCP request.Let's say that I have my local lan on the native VLAN 1. I create a VLAN 25 in the switch and create a fa0/0.25 in the router.In the switch, I plug the cable modem from my ISP in a port on vlan 25In the router, I go to fa0/0.25 and issue "ip address dhcp".The DHCP request goes out, but never comes back. The problem seems to be in the switch because if I try the same thing with a virtual machine I have on a trunked VMWare ESXi server, I get the exact same results. I just don't get the IP address from the ISP.The next step would be to monitor the port on which the cable modem is connected and sniff the packets to see if the DHCP request actually gets back through.

View 17 Replies View RelatedI am trying to setup a cisco 2600 router that will be used to connect to a Qwest internet T1. I will have a Cisco ASA firewall behind the router so that I can build a site to site VPN tunnel. Qwest requires PPP encapsulation. The Lan side network is 10.2.0.0/16. Qwest gave me their serial IP address and my serial ip address which was I used to configure the route. The ethernet interface was configured for the local Lan side subnet and i natted both the inside and outside interface of the router. I am not sure if this is correct. How do I configure the router so that I can use one of the available public IP Addresses as the outside interface of the ASA?

I have some 2620 routers and 2950 switches that have Console Ports that are serial. However my HP PC w.Win 7 dosent have any serial ports. I am looking for a USB to Serial converter that will allow me to access the console ports so I can configure these devices. I've read many old posts and still havent found a solution. Is it true that none of these cables work? Anything that will work on XP? (also have XP PC's).How about a RJ45 to Serial?? How about a PCI Serial card? I cant believe Cisco hasnt developed a conversion cable to use with their Console Cables?
View 4 Replies View RelatedI finally decided to get my own home lab so that I can configure to my hearts' content and not have to wait for access at the school to do it.

I have some 79xx series VOIP phones that are acting VERY strange ... if you are familiar with these series phones once plug them into the PoE switch they look for a TFTP server with the call manager files to acquire all the info they need to work .... i have them set up on a 2620xm router running IOS c2600-ipvoicek9-mz.124-15.T14 along with call manger 4.3. My router is my TFTP server and i have hooked up and fixed over 50 of the same series phones with out a problem.
Now here is my issue ... when you goto press the SETTINGS button on the phone you are allowed to go into the settings of the phone to change all the ROUTER,TFTP,ETC info to allow you to connect your phone to the CALL MANAGER or you can set up DHCP and it will acquire the info automatically. When i press the SETTINGS button nothing happens .... i can reset the phone to factory defaults by holding the # button then 12345678*0# then 2 not saving the info and i can hit the restart buttons which is * 6 SETTINGS buttons together and that will let me restart the phone but i cannot manually set up this phone to do anything .. it will not acquire info form my DHCP server and will not find my TFTP server at all =( the phone SETTINGS BUTTON does not respond at all ..only when restarting the phone.

Is there another setting I should enable? Remember I have made no other configurations bar the ones above.
My configuration is the following
Router ISP >>> Switch 2940 >>> Router 2620 >>> Host (Tacking dhcp from my 2620)
I got servers and other switches 2950 working perfect from the 2940....but the 2620 or even a Switch 3550 (in router L3 port), has the same issue...do not share connection with Host's behind them, I got IP on the host, pinging the Fa0/1 (dhcp), pinging the Fa0/0, but cannot ping the GATEWAY and not surf the internet.
I have a remote location that has a Linksys/Cisco RV042 router [URL] that allows PPTP connections based on username and password combinations. There are no intermediary routers between this device and the internet - only a DSL modem. A secondary WAN connection is not present.
I am able to dial into this VPN using the Windows XP and Windows 7 dialers from any of my local free-wifi locations(e.g. Starbucks). I WAS able to connect to this VPN connection from my house when my home router was a Buffalo brand router.
I have replaced the Buffalo router with a 2620(non-XM) that is connected in ROaS fashion to a 2950 switch. I need some guidance on what in my config is not allowing me to connect to this remote site.
Home network info: Local subnets : 192.168.x.x
Remote network info: Local subnet : 10.214.x.x
The Windows XP dialer client indicates that the username and password challenge is where the connection fails. It ultimately gives me the error code 619. I have performed a Wireshark packet capture of an attempt to connect from ip 192.168.10.11. This packet capture shows multiple "Configuration Request" packets being exchanged between the two endpoints, but does not ever show an exchange of authentication.
My nat translation table shows an entry for both a GRE tunnel as well as port 1723 between 192.168.10.11 and the WAN port of the RV042 when attempting to establish this VPN.
I have attached my 2620 configuration for your review.
I am new to Cisco networking (I just passed my A+ test and am working on my Network + test with an end goal to finish with a CCNP) and I bought a Cisco 2620 XM and a 1605R to figure out how to setup and practice on. In my house we have Verizon Fios with the standard Verizon appliance feeding internet to the rest of the house. My question is that will my Cisco appliances be usable with an out connection from the Verizon appliance? I am concerned because the connection that comes into my room from the Verizon router would be considered a LAN connection, not a WAN? Also in order to configure the router, I believe it needs an RJ-45 to serial to plug into a computer for setting up. My computer doesn't have a serial port so will an RJ-45 to USB work (since that is serial as well)?
View 3 Replies View RelatedI have a lab setup to take my CCNA and CCNP and I'm having issues trying to get WAN connectivity back to a switch at the end of my network. My lab environment consists of 1 - 2950 switch, 1 - 2620 and 1 - 2621XM. I have 1 Ethernet connection from each router to the switch and 1 serial connection from the 2620 to the 2621XM. I have the serial interfaces in a shutdown state right now so there is no loop since I do not have Spanning tree setup on the ports on the switch yet.
Right now using the fast ethernet ports on the routers and I have no issues its when I shut down those Ethernet ports and try using the serial interfaces when I start having issues. So my network layout is Ethernet from switch port f0/4 to port f0/0 on 2620 and serial from s0/1 on the 2620 to s0/2 on the 2621XM. My 2621XM f0/1 is whats connected to the WAN and I have no issues getting to the WAN from my 2621Xm or my 2620 but when I try pinging any website or even my WAN default gateway from my switch I get nothing!
Ive also noticed that when I do a IP NAT translation (after accessing the WAN from my 2620) on my 2621XM the source IP is of my serial connection not the ip of my 2620 router? I have my default gateway on the 2620 as the the IP of my serial interface on the 2621XM and vice versa because my LAN network is 172.16.1.0 and my WAN is 172.16.9.0. I have a /31 setup between my serial connections 172.16.11.0 (s0/1) is on the 2620 and 172.16.11.1(s0/2) is on the 2621XM. I used the SDM (ver 2.5) to setup NAT to have f0/1 with Nat outside and s0/2 as Nat inside. Encapsulation is HDLC between the serial links. Ive attached the running configs of the switch and routers.
I cleared the flash (disk0) on my ASA and now I'm unable to restore it with an IOS.
When I attempt to load it with an IOS, it appears to load just fine. It even proceeds to restart, but when it boots back up it displays the error "No images in / Error 15: File not found. unable to boot an image" and goes to ROMMON.
My computer's IP is 10.0.0.1. I'm assigning the ASA 10.0.0.254. The image filename is asa724-k8.bin. Here's the output of the environmental variables and the attempted loading of the IOS:

My question is that cisco website says there are two type of cable connections for this type of config --which are --T1 CSU/DSU ConfigurationSet one CSU/DSU to clock source internal, and the other CSU/DSU to clock source line. The linecode, framing, data-coding, and timeslots must be set the same on both CSU/DSUs.Four-Wire 56k CSU/DSU Configuration For my network connection which type of config i should use??Secondly i try to connect these ports by normal crossover cable it did not work.So for this type of connection i know i need T1 cross over cable-- which has RJ 48 connections at both sides.I check cable from ebay which is RJ45 RJ48 cross over -- will this cable work in my router to router connection.
I am a recent student to Cisco products and I have purchased some (what I thought was good) lab equipment to learn with on a budget. What I have is a 2948G switch and a 2620 router. My issue is this: the router has only one fast Ethernet port. Is it possible to use V LAN's and V LAN Interfaces on the router and switch to somehow emulate a second interface to connect to a WAN or sub net?
