has somebody found a way to disable the (time consuming) image download that takes place at the beginning of each switch replacement in Smart Install? As far as I see it even if the software version matches the version in the vstack config it is downloaded.
I've been recently testing out the Smart Install feature, and I too have noticed that even when a switch has the newest IOS, there is no version checking before it grabs the new IOS image archive.
I've looked around and I have been unable to find any options or settings to change to mitigate the unneccessary traffic and wasted time.
I'd be interested in seeing if there are any such options.
One other problem I have also noticed with connecting Non-Smart Install capable switches ( < 12.2(52)SE ) is that when it begins the autoinstall, option 150 (TFTP server) is overwritten with the director IP address and does not contain the IP which is defined by file-server in vstack dhcp-localpool. Now this is a problem when using a remote TFTP server as it errors out (TFTP timeout) by trying to retrieve a dummy file from the director IP three times then switching to a broadcast address which fails again if there isn't a TFTP server with the dummy file located on it. Even if there is a dummy file with 0 bytes, it retrieves it three times then continues onto obtaining the client_cfg.txt from the director IP via TFTP (inital config to allow director to telnet and issue the archive download-sw command). Is retrieving the dummy file even neccessary? Is there a way to disable it?
Smart Install seems to be a bigger hassle than it is to do it manually, depending on how your network is setup.
I've been looking into a way to stop it from using the tcp port 4786, however Cisco documentation seems to be sparse for the Smart Install feature. The only way I can see to block external access to port 4786 is using an acl to deny access, however denying everything would most likely break the Smart Install functionality. An allow on the director's IP with a deny all rule following it might work...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
