Virtual machines on blades seeing intermittent PING/ARP issues.

[Casper42]

Don't know the answer here but with newish (3.30+ for CLI and 3.70+ for GUI) you can dump the MAC Table from any given VC module to see where VC is seeing the MAC Address of the VMs that won't ping.

CLI: show interconnect-mac-table enc0:1
enc0 in a single enclosure domain would always be enc0. In a stacked domain it could be enc1/2/3 depending on how many enclosures in the stack. (Use the Enclosures screen in the top left of the GUI to see which enclosure is which.
The 1 after the : is which VC module you want to talk to. 1 is Bay 1, 2 is Bay 2, etc.

GUI: In the bottom left Hardware Screen, expand the Enclosure in question, click on Interconnect Bays, then click on the Interconnect bay you want to interrogate. On the screen that pops up are multiple Tabs and there is a MAC Table tab there.
For LAG XX, look on the 2nd? Tab titled Uplinks to see which connections are which LAG IDs.

Hope that helps you all troubleshoot.
