I used the EFSU method and it was a complete failure, I follwed the instructions very carefully.
as soon as I did the "issu loadversion" the standby chassis did what it was suppose to, reboot. As soon as it came back up with the correct code it reboot again, it went into a rebooting loop that couldn't be stopped. It then attempted to reboot to the old code and it was giving the same mismatch error in show logging. I opened up a severity 1 case and they were able to get it to stop looping by issuing the following command:
redundancy config-sync ignore mismatched-commands
My question now is, should I avoid using EFSU and stick to the standard FSU upgrade method?
1. Just note that when you try to download SXI4 from the Cisco website, you'll be asked to click on a disclaimer. SXI4 has been known to have some destructive bug deemed "almost" critical by Cisco. So if you really, really, really want to use this IOS then it's you're call. Frankly, I wouldn't touch this version with a ten-foot-pole!
2. I tried ISSU once and that was the last. I did the next few IOS upgrade the old-fashion-way: Copy the IOS to both sup-bootflash: and slavesup-bootflash: and then change the bootstring and reboot.
All I'm looking for is a stable code to allow port channel load balancing, source destination IP. What code would you recommend? Also when you guys say reboot, do you mean reload the whole the VSS environment at once?
Thank you all for your feed back. I guess I should've been a little more clear with the source dest ip.
since this is a VSS running SXI1 I'm running into this bug:
EC with enhanced hash method (PFC3C) has no knob to use old method (3B)
Symptom: A PFC3C based system operating in 3C operating mode would automatically include vlan in loadbalance hashing algorithm. Conditions: A PFC3C based system operating in 3C mode. Workaround: none. Further Problem Description:
