IOS upgrade

[rmv72]

I've 2 Cat3750 in stack. I want upgrade IOS to c3750-ipbase-mz.122-25.SEB2

My first question - from docs i found command

archive download-sw /overwrite tftp://*.*.*.*/c3750-ipservices-tar.122-25.SEB2.tar

But this command works for *.tar files. In my case i've *.bin file. Can i use copy command - copy tftp flash?

My second question - After upgrade IOs at first Cat is't necessary to upgrade second Cat or it'll be made automatically?

Hello,

the upgrade procedure should be the same for .bin files as for .tar files, the difference is that the .tar images contain the web based device manager.

Check this document for the installation procedures:

Catalyst 3750 Software Upgrade in a Stack Configuration with Use of the Command-Line Interface

http://www.cisco.com/en/US/products/hw/switches/ps5023/products_configuration_example09186a00804799d7.shtml

Regarding the stack (this is from a previous post):

Upgrades Apply to All Devices in the Stack

Because the switch stack behaves like a single unit, upgrades apply universally to all members of the stack at once. This means that if an original stack contains both EMI and SMI functions on the various switches, the first time a Cisco IOS Software upgrade is applied, all units in the stack will take on the characteristic of the image applied. While this makes it much more efficient to add functionality to the stack, it is important to make sure all applicable upgrade licenses have been purchased before allowing units to be upgraded from e.g. SMI to EMI functions. Otherwise, those units will be in violation of Cisco IOS Software policy.

Hi,

Just to let you know achive CLI command must be used with a .tar file. Using a .bin files gives an error...
