VLAN Translation
VLAN Translation is a simple VLAN swapping on service provider network.
When connecting a large number of networks at service provider, VLAN overlap is a major
issue as customer ‘A’ and customer ‘B’ may use same VLAN tag. Here VLAN translation will
be used to prevent overlaps.
VLAN translation will also be used for joining the segments in large networks also.It is a simple
1 to 1 mapping of VLANs, It will create the VLAN translation by creating policies. The ingress
VLAN translation is port based and egress VLAN is global.
We can enable ingress VLAN translation as source port based and egress VLAN translation as
global.There are up to 32 rules for the vlan translation, including egress and ingress.
