VLAN C
OMMANDS
32-32
• VLAN swapping only supports one-to-one mapping of VLAN IDs
between a VDSL port and an uplink port.
• VLAN IDs must be mapped for both the upstream and downstream
direction.
• The maximum number of VLAN swap entries is 64 per port groups
1-8, 9-16, 17, and 18. However, note that configuring a large number
of entries may degrade the performance of other processes that also
use the Fast Forwarding Processor (FFP) table, such as access lists,
rate limiting, and IP filtering.
Example
This example configures VLAN swapping for upstream traffic between
port 1 and port 18, exchanging VLAN ID 1 for VLAN ID 100. It then sets
VLAN swapping for downstream traffic to exchange VLAN ID 100 for
VLAN ID 1.
show vlan-swap
This command displays the VLAN swapping configuration settings.
