Hi
we using the following topology
1- 2 x N9396TX vPC
2- 2 x C6800 VSS
3- HP blade system C7000 and virtual connect SW (virtualized environment using ESXi 5.5)
4- Cisco CUCM server that have ESXi in vlan 1 (native) and other VMs (Voice VMs) in vlan 100
the configuration:
we configured the N9300 using vPC and 6800 using VSS
hp blade system is virtualized using ESXi 5.5 and we have many VM in native vlan and in other vlans
we connected the hp balde to 6800 via trunking port channel (LACP) using 802.1q with the same allowed vlan and native vlan in both sides and all VM could send and receive data traffic
the when connecting hp blade to N9300 via trunking PO (LACP) using 802.1q (this port channel is vPC member port and port type normal) with the same allowed vlan and native vlan in both sides but we found that the VMs in Native vlan could not send or receive traffic but any other VMs in other vlans could send and receive tarffic
so we have the following situation:
1- when connecting a non virtualized server (in IP range of vlan 1) to N9300 using access port to native vlan (vlan 1) it works without errors
2- when connecting another switch to the N9300 using trunk port (including native vlan) it works and all vlans could forward traffic
3- when connecting virtualized server (this server has VMs in vlan 10 and 20 and native vlan 1) using trunk port, only the traffic from vlan 1 could not be accessed but other vlans could
NOTE: when connecting the CUCM server to the N9300 and the VMs in vlan 100 not powered on, vlan 1 could forward traffic but when power on the VMs in vlan 100 we could access only vlan 100 and lose access to vlan 1 !!
any suggestion to solve this problem?
