type of traffic from different users in one VLAN.

Configuration restrictions and guidelines

When you configure many-to-one VLAN mapping, follow these restrictions and guidelines:
•
Before you configure many-to-one VLAN mapping, create the original VLANs and the
translated VLANs.
•
To ensure correct traffic forwarding from the service provider network to the customer network,
do not configure many-to-one VLAN mapping together with uRPF. For more information about
uRPF, see Security Configuration Guide.
•
To modify many-to-one VLAN mappings, first use the reset dhcp snooping binding command
to clear the DHCP snooping entries.
