How to Install more than one cisco switch same time

[Sherdilkhan2015]

Hi There,

I have one question if any one can help me with that, I have 50 CISCO switches (No IOS in any) with different models of 3560 and 3750 with G's and Non-G's, can any one tell me, is there any way to install IOS on all of them in same time instead of doing one by one?

Hi, for my experience there is no way.
If the switch doesn't have IOS will be start in rommon.
From rommon you can load an IOS using tftpdnld and a tftp server.

Arrange a tftp server and follow these instructions:

rommon 1 > IP_ADDRESS=<temporary ip address of the switch>

rommon 2> IP_SUBNET_MASK=<subnet mask for the above IP>

rommon 3 > DEFAULT_GATEWAY=<default gateway (can be same as TFTP server IP)>

rommon 4 > TFTP_SERVER=<IP address of TFTP server>

rommon 5 > TFTP_FILE=<name of IOS to be used for bootup (including the .bin extension)>

A tftp can handle multi simultaneous connections.

Regards.

If there is no USB ports present, then you'll need to do this one-by-one and using console cable.
