Ethernet Switching and Bridging

  • Flexible VLAN tagging (vSRX and vSRX 3.0)—Starting in Junos OS Release 22.1R1, vSRX and vSRX 3.0 instances deployed on KVM and VMware platforms support flexible VLAN tagging on revenue and reth interfaces.

    You use VLAN tagging to indicate which packet belongs to which VLAN by tagging the packet with a VLAN tag in the Ethernet frame. Flexible VLAN tagging supports transmission of 802.1Q VLAN single-tag frames on logical interfaces on the Ethernet port. With this feature support you can avoid multiple virtual functions on the network interface card (NIC) and reduce the need of additional interfaces.
