The copy method is only a little quicker, but it works. You can either tftp it to each in turn with copy tftp flash1: and so on, or use copy flash4: flash1.
So on this stack, where 4 is the master, dir flash: and dir flash4: will look the same.Ĥ)Now get that IOS image onto the other switches in the stack. You can also refer to a particular stack member’s flash like this: dir flash2.
When you refer to “flash:”, you are always referring to the master. Let’s say there are four switches and the master is 4.Ģ)Use copy tftp flash: and answer the prompts to get your IOS up there.ģ)You can do dir flash: to see that the new IOS is there. Do show stack to find out how many switches are in the stack, and which one is the master. What makes switch stacks different is that you need to copy the IOS to all of the switches. When you are ready to start using it, change the boot system command on the device to point to it, and reload. Make sure there is room for it in the flash of the target device, and tftp it up. Upgrading a switch is like upgrading a router, really.

There are some new IOS commands to automate upgrading of a stack, but I use the familiar manual method.Īll of your stack members really should be running the same version of IOS (even though there’s a chance that if the versions are close enough the stack might still work).

The last step is to reboot the switch and confirm the new firmware after reboot: Switch#reloadĬisco IOS Software, C3750E Software (C3750E-UNIVERSALK9-M), Version 15.If you want to upgrade IOS on a 3750 switch stack follow this procedure My preferred way is to copy the firmware to local flash from a TFTP server. Upgrading the firmware of a Cisco switch can be done in several ways. Switch(config)#boot system switch all flash:/6.bin Upgrading the firmware of a Cisco 3750 switch. Next, let’s finally copy the file from our TFTP Server to the switch and tell the switch to boot the new firmware: Switch#copy t flash:/6.binĭestination filename ?
We have enabled DHCP on the interface of VLAN 1, and then confirmed we have indeed been assigned an IP address. Let’s quickly run through, what we have done here. Interface IP-Address OK? Method Status Protocol My current versions are listed below if anyone has any suggestions: 2 - cisco WS-C3560G-48TS.

We will enable the switch to retrieve an IP address from DHCP: Switch#conf tĮnter configuration commands, one per line. Your network should provide DHCP in our scenario. Next, let’s serial into the switch: Switch#dir flash:/Ĥ58 -rwx 1048 00:01:33 +00:00 multiple-fsģ drwx 512 19:48:23 +00:00 1ĥ7671680 bytes total (36307968 bytes free)Ĭonnect a port of the switch to be upgraded into your existing network, from where the TFTP Server is reachable. Under File –> Configure you can set the TFTP Server Root Directory.
