Layer 2 Switching Commands 836
addition, packets forwarded internally across a stacking link may have
different tags applied than packets forwarded on a local egress port. This is
due to the processing required for forwarding across a stack.
Example
This example configures ports Gi1/0/10 through Gi1/0/24 as CE ports using
VLAN 10 as the service provider VLAN ID. See the example for the
switchport dot1q ethertype command to configure an associated SP port.
console(config)#vlan 10
console(config-vlan10)#exit
console(config)#interface range gi1/0/10-24
console(config-if)#switchport access vlan 10
console(config-if)#switchport mode dot1q-tunnel
console(config-if)#exit
switchport mode private-vlan
Use the switchport mode private-vlan command in Interface Configuration
mode to define a private VLAN association for an isolated or community
interface or a mapping for a promiscuous interface.
Use the no form of the command to remove the private VLAN association or
mapping from the interface.
Syntax
switchport mode private-vlan {host|promiscuous}
no switchport mode
• host-association —Configure the interface as a private VLAN host port.
Host ports are community or isolated ports, depending on the VLAN to
which they belong.
•
promiscuous —Configure the interface as a private VLAN promiscuous
port. Promiscuous ports are members of the primary VLAN.
Default Configuration
This command has no default configuration. By default, a port is neither
configured as promiscuous or host.
