This example enables ingress checking on ports ge-5-1 ~ ge-5-4.
9.6 Automatic VLAN Registration
GARP and GVRP are the protocols used to automatically register VLAN membership across switches.
9.6.1 GARP
GARP (Generic Attribute Registration Protocol) allows network switches to register and de-register
attribute values with other GARP participants within a bridged LAN. GARP is a protocol that provides
a generic mechanism for protocols that serve a more specific application, for example, GVRP.
9.6.1.1 GARP Timers
Switches join VLANs by making a declaration. A declaration is made by issuing a Join message
using GARP. Declarations are withdrawn by issuing a Leave message. A Leave All message
terminates all registrations. GARP timers set declaration timeout values.
9.6.2 GVRP
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 VLAN
groups beyond the local OLT.
Please refer to the following table for common IEEE 802.1Q VLAN terminology.
OLT2412(config)# interface port-channel ge-5-1&&-4
OLT2412(config-interface)# ingress-check
