Hi All,
Am hoping to upgrade our 3650 switches to a more current and up to date version (looks like nobody has bothered to do this yet), reading about the different options am hoping to go for Everest. But am reading some of these version are very buggy.
Deferred Release - to Denali - 16.3.7 (MD) - any issues - cat3k_caa-universalk9.16.03.07.SPA.bin
Deferred Release - Everest-16.6.4a MD - any issues CAT3850/3650 UNIVERSAL cat3k_caa-universalk9.16.06.04a.SPA.bin
Are you able to share your experiences on either version, or any recommended version
Kind Regards

Hi,
this is my personal experience with the 2960-X, First, it is recommended to assign the stack master a higher priority 15 for e.g, so that switch will always be the master.
- the 2nd switch will also need to need to be upgraded to the same version as the rest of the stack before adding. you will get an ios version mismatch message if you dont do this (from experience).
i tend to use the USBport, quick and easy
- once the IOS is upgraded to the latest version on the 2nd swtich - and when you want to connect it to the stack, DO NOT POWER ON THE new 2960x yet, once the stacking cables are connected, then power on. The MASTER doesnt need to be rebooted.
- after the new switch goes through the motions, it will be added as a new stack member, and the config copied to the new switch. in my experience i havn't seen a situation where the Master automatically does the ios upgrade as well, I might have missed that point.
- but i have read, once the both switches are on the stack- u can upgrade the switch using the archive command and that install across all the rest of the switches.
Thanks

Thanks Julio, this is something we haven't though of, the scripting side. Would there be any reference from Cisco regarding this method, as I am fairly new to this field, and haven't done any EEM scripts on live environments.

Hi Everybody
All our remotes sites are connected to our main datacenter via MPLS IPVPN, and for one of these remote sites, we had an additional ADSL connection installed for resiliency. And an IPSEC tunnel has being configured between remote and head office ASA. Have disabled RR on both ends. Redistribute Static configured on the head office FW to EIGRP. Manually added a static route with a higher AD. So once the MPLS connection goes down, and IPSEC tunnel is formed. So no issues. However when the primary connection comes back. EIGRP doesn't switch back to the MPLS route, but prefers the IPSEC path, due to a lower metric, that gets redistributed to the core with an AD of 170.
I know there are a few options like offset lists, redistribute the static with a metric, or a route map.
The config will need to be made on the HO firewall, so what would be the preferred choice.
Any advice would be much appreciated.

Unfortunately they are using a layer 2 Dlink POE Switch. Nothing fancy. What I can't understand is it works on another 5506x firewall. In that I only had to insert an ACL to allow UDP 6000 .

Hi, Thanks for response. The WOL packets are sent using UDP/9- that's what the application is configured to However I don't think the below would work for this situation. As the below commands aren't valid for the ASA. Which is currently running on Routed mode. I did create a sub interface and tried but commands as such. This could work on a layer 3 switch I think.

Hi We are trying to allow UDP broadcast 9 packets via the firewall. Basically WOL packets needs to be send from one network segment to another. And we are also aware '' In routed firewall mode, broadcast and multicast traffic is blocked even if you allow it in an access rule, including unsupported dynamic routing protocols and DHCP. You must configure the dynamic routing protocols or DHCP relay to allow this traffic.'' We tried the following a blog which mentioned tricking the ASA to capture the broadcast packet, and NAT this as a Unicast to the broadcast address of the destination address. https://**bleep**.technology/forwarding-wake-on-lan-using-a-cisco-asa The above didn't work for us, may be we did it wrong. Has anybody come accross the above scenario, and manage to trick the ASA to send broadcast packets.
