• You can also use one of three show commands that are specific to the Private VLAN feature:
•
show interfaces private-vlan [interface interface]: Display the type and status of the configured PVLAN
interfaces. Refer to the example output in the Security chapter of the FTOS Command Reference
Guide.
•
show vlan private-vlan [community | interface | isolated | primary | primary_vlan | interface interface]:
Display the configured PVLANs or interfaces that are part of a PVLAN. Figure 22-4 shows the
results of using the command without command options on the switch in the topology diagram
shown in Figure 22-3.
•
show vlan private-vlan mapping: Display the primary-secondary VLAN mapping. Refer to the
example output from the MXL Switch in Figure 22-4.
• Two
show commands revised to display PVLAN data are:
• show arp
• show vlan: Refer to the revised output in Figure 22-5.
