The default transfer speed of TFTP can be exceptionally slow, for example I was getting 1MB a minute (~20Kbps) across core infrastructure which can and does do 1Gbps/10Gbps regularly. For me it helped as I didn’t have a physical interface / SVI in my management VRF on this device but I did have a loopback.
NB#2: You can set the source interface to a loopback in case that helps. NB#1: This will also set it inside a VRF if that interface has a VRF on it. To set your source interface for a TFTP download you only need 1 line of config and you need to be inside the global configuration level: ROUTER(config)#ip tftp source-interface loopback 100 We can verify that the newer version of IOS is being used by issuing the show version command: SW1#show versionĬisco IOS Software, C2960 Software (C2960-LANBASEK9-M), Version 15.0(2)SE4, RELEASE SOFTWARE (fc1)Ĭopyright (c) 1986-2013 by Cisco Systems, Inc.This quick little article is around tips for using TFTP with Cisco kit. The last step is to save the configuration and reload the device. This command accepts a single parameter – the name of the file to load: SW1(config)#boot system Ĥ. The easiest way to do it is by using the boot system command. We need to instruct the switch to load the new file. If we reboot the system now, the old IOS file will be loaded: SW1#reloadĬ2960 Boot Loader (C2960-HBOOT-M) Version 12.2(25r)FX, RELEASE SOFTWARE (fc4)Ĭisco WS-C2960-24TT (RC32300) processor (revision C0) with 21039K bytes of memory.īase ethernet MAC Address: 3B
The last step is to configure the switch to load the new IOS version. We’ve also specified that the destination filename will be the same as the source filename.īy issuing the show flash: command, we can see that the file was copied to the switch: SW1#show flash:ġ -rw- 4414921 .binģ -rw- 4670455 Ħ4016384 bytes total (54929956 bytes free)ģ. Notice how we need to enter the IP address and the exact filename of the image we wanted to copy. This can be done by issuing the copy command on the switch:Īddress or name of remote host ? 10.0.0.100 Next, we need to transfer the file from the TFTP server to the flash memory of the switch. We need to place the image file to a TFTP server that is reachable by the switch:Ģ. Let’s upgrade Cisco Catalyst 2960 to a newer version of IOS via TFTP. The downloaded file must then be transferred to a flash drive of the device, usually via TFTP or FTP. This is usually done by logging in at and selecting your device type and version. Before upgrading IOS, you need to obtain the latest IOS version.
