Addition of SVLAN
Specified here sample of switch configuration shows how to add mark SVLAN 20 to all VLAN except
for VLAN 27.
console#configure
console(config)#vlan database
console(config-vlan)#vlan 20,27
console(config-vlan)#exit
console(config)#interface GigabitEthernet 1/0/24
console(config-if)#switchport mode trunk
console(config-if)#switchport trunk allowed vlan add 20,27
console(config-if)#selective-qinq list ingress add_vlan 27
console(config-if)#selective-qinq list ingress permit ingress_vlan 20
Substitution of CVLAN
In communications networks quite often occur aims related to substitution of VLAN (e.g. for
switches of level of access there exists typical configuration, but user traffic, VOIP and traffic for control
are required to be transferred in different VLAN to different directions). In this case it would be
comfortable to use CVLAN substitution function for changing typical VLAN to VLAN for required direction.
Below you can find switch configuration in which substitution of VLAN 100, 101 and 102 to 200,201 and
202 is made:
console#configure
console(config)#vlan database
console(config-vlan)#vlan 200-202
console(config-vlan)#exit
console(config)#interface GigabitEthernet 1/0/24
console(config-if)#switchport mode trunk
console(config-if)#switchport trunk allowed vlan add 200-202
console(config-if)#selective-qinq list ingress override_vlan 200 ingress_vlan 100
console(config-if)#selective-qinq list ingress override_vlan 201 ingress_vlan 101
console(config-if)#selective-qinq list ingress override_vlan 202 ingress_vlan 102
Configuration of multicast-TV VLAN
Function "Multicast-TV VLAN" gives possibility to use one VLAN in operator's network for
transferring multi address traffic and deliver this traffic to users even if they are not members of this
VLAN. By means of "Multicast-TV VLAN" function load to operator's network can be decreased due to
absence of backup of multi address data, e.g. when providing IPTV services.
Application of the function assumes that ports of users operate in "access" or "customer" mode and
belong to any VLAN except for multicast-tv VLAN. Users can only receive multi address traffic from
multicast-tv VLAN and cannot transfer data in this VLAN. Besides multicast traffic source port of the switch
shall be configured, this port shall be member of multicast-tv VLAN.
