Selecting How VLAN Membership is Implemented for Extended Ports
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. 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 set the way VLAN membership is implemented, use the following command:
configure forwarding vpex vlan-port-filter [hash-table | port-group]
To see the current selection for VLAN membership, use the command:
show forwarding configuration
