configure forwarding vpex vlan-port-filter
Selects the way VLAN membership is implemented for Extended Edge Switching extended ports.
Specifies Extended Edge Switching.
|vlan-port-filter||Select hardware mechanism to enforce VLAN port membership.|
|hash-table||Use hash table for VLAN port membership when different VLANs do not share many ports (default).|
|port-group||Use port group for VLAN port membership when different VLANs share many ports and there is a requirement for large VLAN scale.|
Hash table is the default behavior.
In Extended Edge Switching hardware, the extended ports are represented as virtual ports. The VLAN membership of extended ports can be implemented in two ways:
- Hash table with VLAN and virtual port as key. Note that hash tables can lead to hash collisions at higher scale. (Default)
- Virtual port group. Programming the same group number in the VLAN table and virtual port table indicates membership. The hardware has 64 virtual port groups. You should select this option if many VLANs share the same extended ports.
To see what setting you have selected with this command, see show forwarding configuration.
The following example selects a virtual port group to define VLAN membership:
# configure forwarding vpex vlan-port-filter port-group
This command was first available in ExtremeXOS 22.6.
This command is available on ExtremeSwitching X465 and X590 series switches.
