text: **11.8.4 VLAN support**
  
  Starting with V7.4, VLAN tagging is supported for both iSCSI host attachment and IP 
  replication. Hosts and remote-copy operations can connect to the system through Ethernet 
  ports. Each traffic type has different bandwidth requirements, which can interfere with each 
  other if they share the same IP connections. VLAN tagging creates two separate connections 
  on the same IP network for different types of traffic. The system supports VLAN configuration 
  on both IPv4 and IPv6 connections. 
  
  When the VLAN ID is configured for IP addresses used for either iSCSI host attach or 
  IP replication, the VLAN settings on the Ethernet network and servers must be configured 
  correctly to avoid connectivity issues. After the VLANs are configured, changes to the VLAN 
  settings will disrupt iSCSI and IP replication traffic to and from the partnerships.
