==================================

vconfig 이용 방법
# vconfig add ens37 20
# cat /proc/net/vlan/config  //vlan 생성한것 확인

#ifconfig ens37.20 192.168.20.1 netmask 255.255.255.0 up
#vconfig rem ens37.20   //삭제

==============================
ip link 이용 방법

#ip link add link ens37 name ens37.30 type vlan id 30
#ip link show ens37.30
# ip link delete eth37.30   //삭제
#ip a

[Network] Vlan 할당하여 tag로 interface 구성

리눅스에서 vlan을 tag(태깅)해서 사용하는 방법 우선 vlan 태깅을 위해서는 관련 모듈이 필요하다. 기본적으로 OS에 있지만 혹시 모르니 확인해주도록 한다. # modinfo 8021q # lsmod | grep 8021q 만약 모듈
