ERS3500 drops VM-Network after reboot
« on: January 18, 2017, 08:19:40 AM »
Hi all,

we have an ERS 35xx stack (2x24+1x48), fw= / sw=

attached are multiple ESX-Nics with multiple vSwitches. Teaming is only configured at the ESX (ID of virtual port..), no MLT or LACP on the ERS35xx. This configuration runs for years, but last weekend one of the stack members "freezes" and we had to reboot the stack.
Since then, all vm-network-ports are "offline", the vms are not pingable. Management Network is reachable.

We tried to deactivate/activate the ports and nics, in hope that the ESX recognizes traffic and the observed IP range in the vswitch fills correctly.

We further tried in coop with AVAYA to create a MLT with "advanced mode" and "learning disable", and on the ESX a loadbalancing based on IPHash.
But nothing works....the ports on the ERS3500 are still "down", means there is traffic on the port, but the Switch seems to drop it....

Any suggestions or ideas will be welcome

fixed! - once again the ERS and not ESX-side!
While configuration seems correct, the switch lost his default vlan across the stack....ports are configured but not working
