I have tried formatting the CF card on an 1841 but the 3725 won't read it. It is obviously stuck at ROMMON
What is the correct way to format a CF card so my 3725 will read it and I can get an iOS back on it!!
I had an issue today on a 4507r today where when I formatted the compact flash in slot0: (512mb) it caused the CPU to spike to 100% this took about 1.5 hours and did not cause adjacency loss or any thing, but was worrisome. This was a sup IV is this normal and should u let it complete like I did? Also when I copied the os to it from boot flash it caused the same behavior. I have done this a bunch in 6500 sup 720 without this issue?
View 3 Replies View RelatedI recently tried to manually format the flash on a model WS-2960S-48TS-L switch running IOS version 15.0(2)SE. While executing the operation I got the following error - mifs[8]: Failed to create superblock %Error formatting flash (I/O error).As a result the flash is no longer accessible by the switch. I spoke with Cisco and they indicated that a switch reload would remount the flash and make it accessable again but the .bin file would need to be reloaded using the xModem recovery procedure (what a pain).The next IOS version 15.0(2)SE1 will supposedly fix this bug but it has not been released yet. In the meantime if you are running 15.0(2)SE you may want to hold off performing a "format flash:" function on a 2960S.
View 3 Replies View Relatedcorrelates the older IOS format naming compared with the newer? I have an older catalyst 3550 that might need an IOS upgrade due to us starting to implement dot1x. The reason that I say this is that some of the commands in the dot1x config guide, such as aaa accounting dot1x, are not valid on this platform. The current IOS is c3550-i5q3l2-mz.121-8.EA1c but the newer format is the ipbase, ipservices, etc. format. There is a newer ios but how do I convert from one to the other? I think I need to research the IOS to see if the new commands are there as well as I want to make sure there are no gotchas from a hardware standpoint if I upgrade.

View 5 Replies View RelatedI have got a PC at work (Windows XP Pro SP3) that is on two networks with the IPs 10.20.30.167, subnet 255.255.255.0 (internet enabled) and 10.0.0.20, subnet 255.255.255.0 (no internet). On the 10.0.0.X network there is a gateway with the IP 10.0.0.200 allowing access to another network; 192.168.60.X, subnet 255.255.255.0 (no internet). I have added the route on my work PC to access the 192.168.60.X network via this gateway and I can access all PCs on all three networks from this PC.Now, I am using LogMeIn Hamachi so that I can access the networks at work from home. The PC at work is the 'gateway' PC on the Hamachi network. When installing Hamachi it created a new network connection and bridged this connection with my 10.20.30.167 network adapter to allow access to the 10.20.30.X network from an external PC when connected using the Hamachi VPN connection. I have manually configured my Hamachi connection on my PC at home to the IP 10.20.30.169, subnet 255.255.255.0, with the default gateway set to 10.20.30.167. I can ping all computers on the 10.20.30.X network from my PC at home.
I then added a route on my PC at home for 10.0.0.X to go via 10.20.30.167 (the 'gateway' on the Hamachi network). I also enabled IP forwarding on the 'gateway' PC (my PC at work). I can not ping any PC on the 10.0.0.X network from my PC at home apart from 10.0.0.20 (the other NIC in the Hamachi gateway PC) and 10.0.0.30 (another PC on the 10.20.30.X network that is also on the 10.0.0.X network).Now, with IP forwarding enabled on the Hamachi gateway PC I would assume after adding the route on my PC at home for 10.0.0.X traffic to go via 10.20.30.167 that I would be able to ping all PCs on the 10.0.0.X network...I also tried adding a route on my home PC to send all traffic for the 192.168.60.X network via 10.20.30.167 which has a route via 10.0.0.200 to the 192.168.60.X network, but this also did not work.I then tried adding the 10.0.0.20 network adapter into the network bridge that the Hamachi connection made, also keeping both IPs (10.20.30.167 and 10.0.0.20) on this network bridge by adding them into the 'IP Settings' in the 'Advanced TCI/IP Settings'. I also added the 10.0.0.200 gateway for good measure. I still cannot ping any PC on the 10.0.0.X or 192.168.60.X networks from my PC at home.
I have also added the route to the 10.20.30.X network on a PC on the 10.0.0.X network to go via 10.0.0.20 and tried pinging a PC on the 10.20.30.X network but this also has not worked. Also setting the default gateway on a PC on the 10.0.0.X network to 10.0.0.20 does not allow this...Surely bridging the networks 10.20.30.167 and 10.0.0.20 on my work PC would allow another PC on the 10.0.0.X network to access the 10.20.30.X network after adding the route or setting 10.0.0.20 as the default gateway?
I have two computers. Computer A is connected to the internet through GSM network. Computer A also have NIC adapter which is connected to local network with IP 192.168.33.10/24.
Computer B in connected to internet with DSL connection.
On both machines I use TeamViewer to make VPN secure tunnel between this two computers. Computer A gets IP:7.200.100.2 Computer B gets IP:7.200.100.3
How can I access from computer B to specific device with IP 192.168.33.250 which is on local network of computer A?
Is it possible to route traffic from VPN to other local network, or it is some possibility to use port forwarding from VPN connection to specific IP address on the local network to specific port number?
We have a PPPoE DSL link with a dedicated IP providing by a small ISP(ISP A) in Canada. We are having trouble reaching a small group of IPs in the US to be able to access some client resources.We have eliminated all possible local issues by removing the firewall and making a direct connection to the ISP. We have also had numerous tests prove successful when we use other local ISPs.
Trace routes show that the packets get dropped a few hops from the destination on a US ISP(ISP B).The routes even appear to be very similar to the other ISPs we tested. We escalated to ISP A and they say that everything is working properly on their end and the problem is with ISP B. They claim they "have no partnership with ISP B and therefore cannot create a ticket to get it resolved". I tried calling ISP B but I get nowhere because I am not a customer of theirs.
My solution is to give ISP A the boot, but management has denied that request because of the amount of effort required to switch over. How I can escalate this? Is there anyway to go over and above the ISPs?
I have an skill exercise with 4 Routing Protocols Default Route,Static Route,Eigrp, Ospf. I have about 6-7 routers, and each of them has an routing protocol. But the problem is the Main router INTERNET, which it has to use Static in a direction, and default in the opposite path. This is the scheme of routers and how the r.protocol have to be configured.

View 2 Replies View RelatedI've been timing out via any FTP client, including FileZilla, FireFTP, and a few others. I even downloaded a few just to see if I could connect with other clients.I contacted my host who can't recreate the issue on their end. I contacted my ISP who instructed me to use my command prompt in order to connect to their server, and that of mozilla. Both times I was able to connect via the command prompt.I don't understand what's going on.If I can connect to the sample sites that my ISP gave me, why can't I connect using an FTP client any longer. What possible change could have been made to have caused that disconnection that happened a few nights ago, and is now causing the timeouts I continue to receive?

View 6 Replies View RelatedI have two different networks on same LAN.One net has public 2xx.x.x.x IPs (some on DMZ, they are servers with their own internal firewalling) and goes through a GBeth switch to a Cisco 25xx router for accessing HDSL modem with several HDSL trunks and then Internet. That router is configured to let external IPs access only DMZ IPs, of course.The other net has 192.168.x.x IPs and goes through another GBeth switch to a DLink router to access ADSL. Mainly for download traffic at a low flat cost.I would like to have a way to let the 192.x.x.x machines access the servers on the DMZ of the 2xx.x.x.x net without going outside the physical LAN. The servers host mail services and so sending heavy attached documents needs a hi-speed LAN connection and certainly not the ADSL upload capability. Not to say about servers web contents maintenance.
