Cisco :: IP Phone Getting Firmware From TFTP Server?
Jan 8, 2012
I have a questions on an Ip phone when getting the firmware from the TFTP server (e.g. CME) after bootup,- After the registration with CME, the IP phone will getting an auto config file which is the Default.xml file. - The CME will acts a a TFTP server which contains all the IP phone's firmware for different models like 7970 and 7640 in different directories.- The CME have configured with the directory path for all the IP phone when the IP phone come to TFTP and acquired the firmware.Let say I have a phone registered is 7970 and what is the mechanism that governs that my 7970 is not downloading the wrong firmware from the TFTP? Let say it might wrongly downloaded the 7640 firmware? Who take care of this? The phone itself? or the CME will tell the IP phone to take only the 7970 firmware via the Default.xml file?
I am trying to implement a small VoIP LAN (you can see the lan in attachments)for a personal project. I am using:
- 2 x XP (on which i installed Cisco IP Communicator 7.0.3.0) - 1 x Ubuntu (running GNS3 with a c3600 Router)
The problem is that the phone which is not in the same LAN with the tftp server cannot register.
1) Can a phone register to a tftp server from another LAN ? 2) If the answer for 1) is yes, what am i doing wrong (you can see the details in the attachments)? I mention that the ping works well anywhere in the LAN.
I wonder if dir825 with ddwrt firmware are able to set up additional tftp server? I try to serve dir825 both as tftp server and dhcp server to allow remote client to have pxe booting from it. ( the booting image file would be located in external HD attatched to dir825's usb port )
We have a LMS 4.2 installed. And I see the tftp port is open on it. however, every time, i tried to "copy running tftp" to the LMS from a switch, it says the Trying to connect to tftp server Connection to Server Established.TFTP put operation failed:Access violation
i seem not be able to find where to configure the tftp server.
all this inside the router or the switch. From the Linux box just running a simple command such as:
tftp 172.16.0.3 -c get startup-config newbackup.conf
where 172.16.0.3 is the IP address of the switch and newbackup.conf is the name of the config file stored on the Linux machine.So, how do I do that with an ASA box? how to backup ASA from inside it.
How do i go about setting up a TFTP server from laptop to Cisco ws-C3750 48P Switch, I need to pull the image off the switch and place it on an other switch that has a corrupt image, The switch which is corrupted is the same as above Cisco ws-C3750 48P.
I am trying to convert two Aironet 1141n access points to autonomous stand-alone units. I have connected the console cable and I can see the unit giving information in the console window, but I cannot type any commands. When I try to get the unit to upload the c1140-k9w7-tar.default file by holding the mode button in for 20-30 seconds, it shows it is examining the file, and then states that the connection to the tftp server has timed out. My windows firewall is off, the interface is configured as 10.0.0.2 255.255.255.0 and the tftp server is showing that.
I have been trying to get a PIX 501 firewall reset and have been having the hardest time. Im a student and this is my first experience with a firewall. I have been going through the steps here URL,I cant seem to connect to the tftp server, I have several nic's on my computer and tried them both and even plugged the firewall to the router and tried to use the gateway to connect but it doesn't seem to want to even ping for me.
I have been looking at grading the IOS version on our 6509-E however there is not enough space on disk:0 to upgrade to the version I need to install. The question I would like to ask is - is it possible to boot the IOS from a TFTP server? If this is possible what configuration do I need on the 6509 to enable this. How does the 6509 know about the TFTP server as an IOS is not installed and therefore it will not have a network configuration
I have a Cisco 831 router (c831-k9o3y6-mz.124-5c.bin) that cannot backup the config to a local tftp server. I have seen this behavior on a few different Cisco devices over the years and have never found a solution. The connection is made to the tftp server (in this case tftpd but similar behavior on any tftp server) and a blank file is created on the target machine file system, but the data is never transferred.
The router shows %Error opening tftp://192.168.0.2/router-confg (Timed out) [Failed] The tftpd log shows 5 repeated attempts at the file write.
Connection received from 192.168.0.1 on port 53570 [25/05 11:56:40.922] Write request for file <router-confg>. Mode octet [25/05 11:56:40.922] Using local port 61607 [25/05 11:56:40.922] <router-confg>: rcvd 0 blk, 0 bytes in 3 s. 0 blk resent [25/05 11:56:43.922] Connection received from 192.168.0.1 on port 53570 [25/05 11:56:43.923]

This is also stopping me upgrading the image on the router as I cannot transfer in the other direction either.
Recently had an external security scan done on my DIR 655 and scan results are stating I have an accessible TFTP Server running. i've been through all the settings, and even upgraded to the latest firmware. Yet security scans are telling me I've got a TFTP Server running. Why would one be showing on the external interface, and how can I stop it?
I am facing a constant problem with cisco 7940 Ip Phones.
- I am able to configure it from Call Manager. -But after that the phones starts restarting. - I heard there is some issue with CISCO 7940 Farmware in recent times.
When I place the phone on a different subnet, registration failed. The connectivity between the two subnet should be working because I have a desktop computer hook up behind the Avaya phone and the computer can talk with the server without problemThe phone has gotten the IP from DHCP server can I can even ping the IP from phone server. but on the phone it shows "Discover 10.0.10.10" then reboot, again and again. 10.0.10.10 is the IP of phone server. And there is no firewall rules blocking the traffic between the two subnet.Like I said before, if I place the phone on the same subnet as the server it worked. The setting of the switch remain unchanged
I have time warner cable, they have a service where you can watch TV on your hand held devices.. Only issue is, you have to be on your home network. since thats fairly pointless since if i am home i am watching the 60 inch... i was trying to use VPN to get inside of my network to effectivly fool the app to thinking i was on my home network.
I have an issue on the Cat 3750 on the voice vlan; IP Phone not registering with PBX & Signaling Server. The ip phone hits dhcp and gets an ip address from a data scope. Data scope does have dhcp options for voice, same as voice scope so it should work but it doesnt.We removed the switchport access vlan 50 command, and left the switchport access voice vlan 51, and now the phone registers.Anything I can check on the switch to make sure voice vlan is working? Any debug voice vlan commands?The switch doesnt seem to distinguish voice and data traffic.I check dhcp and both scopes vlan 50 and vlan 51 have the same configuration. Defautl GW is different of course Catalyst 3750 is running 12.2(25)SEE2 [code]
We have 2mbps leased line and have Cisco 1841 which is managed by our ISP. I have hooked up another 1841 (please find basic config below, it will get more complex lateron) Now when I connect my laptop I am able to browse Internet. But when I conect VOIP phone, it is not able to contact it's Hosted Server on Internet.
VOIP phone is Polycom SoundPoint 550 and I get URL call disabed message. If I try netgear Firewall everything seems to work.that the voip provider needs following ports UDP Range 16384 - 32766, TCP 5060 & UDP 5060. But in my config all outbound traffic is allowed. [code]
I am using TFTPD32 to upgrade the IOS on a router. When I type in the commands copy tftp flash and enter all the necessary information, the router sits for a minute or so and then times out. There is no entry made in the log when it times out. copy flash tftp yields the same result. The fa 0/0 interface and the TFTP server are both on the same subnet and can successfully ping one anothe
we are looking to use the new firmware's DHCP server feature to setup different DHCP scopes for 5 different VLANs configured on the switch. I see where to turn this on and setup the scope however I can't clearly see where I can assign the specified scope to each VLAN on the switch.

I have a n750 and I did the firmware update on the router and I have it check for firmware updates when I log in and i keep getting this message: "Cannot connect to the firmware information server,please double check the WAN connection." I have access to the internet.
I'm having trouble TFTPing a configuration from my 851 Router to my computer through a IPsec VPN tunnel that this router is connected though. I am able to telnet and ping all devices on the far-end with no problem. I can TFTP a config from a switch behind this router, no problem. I am guessing this problem is related to an ACL on the router. I am also having trouble connecting to this router using the Cisco Config Professional. Discovery will fail, with connection could not be established or HTTP service is not enabled. I have enabled HTTP service. The CCP works fine when I am on the router's subnet.
I've got a fully working 877w that I'm trying to get to boot from tftp, but I just can't seem to get that going.I have a tftp server running and can copy images back and forth without any trouble.I have this in my config:boot-start-markerboot system tftp c870-advipservicesk9-mz.124-24.T2.bin 192.168.1.200boot-end-markerDuring the boot process I get an error message that says there is a missing or illegal ip but I really don't see how that can be as my tftp server is 192.168.1.200 just like my config says.
ASR 1004, has a image, which is on the harddrive, not bootflash and we have no boot commands in the configuration…We are running the ROMMON version ‘15_01rs’ The ASR boots into Rommon, as it cannot find a image (as expected), as the configuration has no boot commands.Trying to TFTP or getting an IOS back into bootflash is proving problematic.Follow all TFTP commands..
I need Cisco router 2800 series boot ios image from network(tftp), when flash is corrupted or router doesn't see it, so it is impossible ? Command, i used boot system tftp: ios.bin but this does not work.
I'm trying to automate our rollout process with kiwi cat tools. I want to copy a file via TFTP or FTP: Cisco tftp menu knows the latest ip address which it was connected to.
I am trying to TFTP an image to a Cisco 2504 WLC. The management interface is 10.1.1.1 /24 and I have my PC connected to a port on the WLC with the IP address 10.1.1.10. However, I still do not have connectivity between the PC and WLC.
