GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a way for
switches to register necessary VLAN members on ports across the network. Enable this
function to permit VLANs groups beyond the local switch.
An example is shown next.
• Enable the IEEE 802.1Q tagged VLAN command to configure tagged VLAN for the
switch.
• Enable ports one, three, four and five for configuration.
• Enable GVRP on the interface.
Figure 150 gvrp Command Example
33.8.7 ingress-check
Syntax:
ingress-check
Enables the device to discard incoming frames for VLANs that are not included in a port
member set.
An example is shown next.
• Enable ports one, three, four and five for configuration.
• Enable ingress checking on the interface.

33.8.8 vlan-trunking
Syntax:

Enable VLAN Trunking on ports connected to other switches or routers (but not ports directly
connected to end users) to allow frames belonging to unknown VLAN groups to pass through
the switch.
An example is shown next.
• Enable ports one, three, four and five for configuration.
• Enable VLAN Trunking on the interface.
