To view all FDB entries including those created for a PVLAN, use the command:
show fdb {blackhole {netlogin [all | mac-based-vlans]} | netlogin [all | mac-based-vlans] | permanent {netlogin [all | mac-based-vlans]} | mac_addr {netlogin [all | mac-based-vlans]} | ports port_list {netlogin [all | mac-based-vlans]} | vlan vlan_name | vlan_list {netlogin [all | mac-based-vlans]} | {{vpls} {vpls_name}}}
The P flag marks additional FDB entries for PVLANs.
