When using a shared network interface on a Citrix SDX appliance with several instances, enabling VLAN tagging (802.1q) on all interfaces is essential. VLAN tagging helps differentiate and direct traffic from different instances by adding tags to Ethernet frames, identifying which VLAN each frame belongs to. This prevents traffic collision and ensures that data from different instances doesn’t interfere with each other, maintaining proper traffic flow and network efficiency.
Shared Network Interface: This means multiple Citrix ADC instances share the same physical network interface card (NIC). VLAN Tagging (802.1q): This technology adds a tag to Ethernet frames to identify which VLAN (Virtual Local Area Network) the traffic belongs to. This allows multiple virtual networks to coexist on a single physical interface. Without VLAN tagging: Traffic from different instances would collide, leading to data corruption and connectivity issues.
