Netgear XCM8806 - 8800 SERIES 6-SLOT CHASSIS SWITCH 사용자 설명서

Learning

A port in the learning state does not accept ingress traffic or perform traffic forwarding, but 
it begins to learn MAC source addresses. The port also receives and processes STP 
BPDUs. This is the second transitional state after listening. From learning, the port will 
change to either blocking or forwarding. 

Forwarding

A port in the forwarding state accepts ingress traffic, learns new MAC source addresses, 
forwards traffic, and receives and processes STP BPDUs.

Disabled

A port in the disabled state does not participate in STP; however, it will forward traffic and 
learn new MAC source addresses.

Binding Ports

The two ways to bind (add) ports to an STPD are: manually and automatically. By default, 
ports are manually added to an STPD.

The default VLAN and STPD S0 are already on the switch.

To manually bind ports, use one of the following commands: 

configure stpd <stpd_name> add vlan <vlan_name> ports [all | <port_list>] {[dot1d 

| emistp | pvst-plus]}

configure vlan <vlan_name> add ports [all | <port_list>] {tagged | untagged} stpd 

<stpd_name> {[dot1d | emistp | pvst-plus]}

The first command adds all ports or a list of ports within the specified VLAN to an STPD. For 
EMISTP and PVST+, the carrier VLAN must already exist on the same set of ports. The 
second command adds all ports or a list of ports to the specified VLAN and STPD at the 
same time. If the ports are added to the VLAN but not to the STPD, the ports remain in the 
VLAN. 

For EMISTP and PVST+, if the specified VLAN is not the carrier VLAN and the specified 
ports are not bound to the carrier VLAN, the system displays an error message. If you 
configure MSTP on your switch, MSTP does not need carrier VLANs. 

The carrier VLAN’s ID must be identical to the ID of the STP domain.
