tagged port-list Configures the indicated ports as Tagged for the
specified S-VLAN. The no version sets the ports to
either No or (if GVRP is enabled) to Auto.
untagged port-list Configures the indicated ports as Untagged for the
specified S-VLAN.The no version sets the ports to
either No or (if GVRP is enabled) to Auto
forbid port-list Dynamic trunks cannot be involved as a part of any
static configurations like forbid. Forbid can only
be applied on ports and static trunks .The forbid
configuration can be applied to only PPORTS and
Static Trunks (Trk1….Trk144), and not to Dynamic
LACP Trunks (Dyn1….Dyn144.)
The no version sets the ports to either no or (if GVRP
is enabled) to Auto.
auto port-list QinQ S-VLAN mode only. Available if GVRP is
enabled on the switch. Returns the per-port settings
for the specified S-VLAN to Auto operation. Auto is
the default per-port setting for a static VLAN if GVRP
is running on the switch.
NOTE: Since provider-gvrp is not supported in a QinQ mixed VLAN mode
environment, the forbid and auto configurations are available only in QinQ
S-VLAN mode.
In QinQ mixed VLAN mode
An interface (port or trunk) must be explicitly GVRP-disabled before it can be assigned to the
S-VLAN space. When you first attempt to configure a port as tagged for an S-VLAN, the CLI will
issue a message disallowing the configuration.
config#: svlan 200 tagged a1,a2 GVRP enabled ports cannot be members of svlans.
Disable the interface level gvrp configuration.
To disable GVRP at the interface, issue the following command:
config#: interface a1,a2 unknown-vlans disable
When you configure the port, the CLI will issue a warning prompt:
config#: svlan 200 tagged a1,a2 Ports a1, a2 will lose their cvlan memberships if any
Do you want to continue? [y/n]
Press Y to continue and automatically configure both ports as port-type provider-network (the
default for all S-VLAN member ports).
Configuring port-types
When QinQ is enabled on the switch all S-VLAN member ports must be categorized as either
port-type customer-network or provider-network (See Figure 79 (page 329)).
