Viprion w/ VCMP Guest loss of network connectivity - Solved

Jason, We recently had an issue that sounds similar and came across your post. We didn't hard reboot but had connectivity issues that would come and go. Was constantly flapping all the monitors on the box. Running vCMP in 11.4.1 HF2. Support kept trying to go down the arp/l2 issues rabbit hole. Was able to figure out the packets didn't even show up in tcpdump. So TMM wasn't even trying to send it out. They were at a loss. Eventually did this - https://support.f5.com/kb/en-us/solutions/public/13000/000/sol13030.html This guest was configured on 2 slots. Soon as we switched over to the other slot it was working. Did the above solution on the slot that was having issues. When it came back online we switched back to that slot and problem was gone. The MCPD creates a binary image of the config to use and each slot creates its own. Theory was this got messed up. Reboot’s won’t fix it. May or may not be related. Just thought I would share in case it helps anyone out. Thanks, Chad
