Feature Limitations
- VLAN mapping can be configured only on a trunk or hybrid interface, and the hybrid interfaces on the devices except the S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-HI, S6730-H, S6730S-H, S6730-S, and S6730S-S must be added to the translated VLAN in tagged mode.
When N:1 VLAN mapping is configured, the interface needs to join the original VLAN in tagged mode.
When VLAN mapping is configured, it is not recommended that map-vlan be configured for the VLAN corresponding to the VLANIF interface.
- If VLAN mapping and DHCP are configured on the same interface, it is recommended to add the interface to the original VLANs (VLANs before mapping) in tagged mode. Ensure that the VLANs before mapping have been created.
- N:1 VLAN mapping is not supported in a stack scenario.
- Configuring MAC address limiting and N:1 VLAN mapping simultaneously causes a high CPU usage on some low-end switches, so such configuration is not recommended.
- A VLAN bound to a BD cannot be specified as the value of map-vlan (the outer VLAN ID in the mapped tag) in VLAN mapping commands. Similarly, a VLAN specified as the value of map-vlan in VLAN mapping commands cannot be bound to a BD.
- After VLAN mapping is configured on an interface, a voice VLAN cannot be configured on the interface.
