Hello All,
It's my first post so I would like to say Hello to All Mambers. I'm network engineer since 15 years but my experience is rather in transsmision and data network (like C(D)WDM,SDH, Metro Ethernet etc.), not operating system. I'm trying to establish some Linux machines on PVE and I need separate VLANs for them. I've read quite lot information on Proxmox wiki and formu, OpenVZ pages etc. I've configured test PVE enviroment and network, but it not working properly. Ping sended from contrainer is sended to Vlan interface on Cisco switch (is added to Arp table), but finaly at contrainer I get massage:
I have no idea where is an error. When I configured interface eth0.2 in CT I seen ARP requests but I didn't get ARP reply from L3 switch.
Best Regards
Marcin
