Cisco Systems 3560 사용자 설명서

Although the switch supports a total of 1005 (normal range and extended range) VLANs, the number of 
routed ports, SVIs, and other configured features affects the use of the switch hardware. 

The switch supports per-VLAN spanning-tree plus (PVST+) or rapid PVST+ with a maximum of 128 
spanning-tree instances. One spanning-tree instance is allowed per VLAN. See the 

 for more information about the number of 

spanning-tree instances and the number of VLANs. The switch supports both Inter-Switch Link (ISL) 
and IEEE 802.1Q trunking methods for sending VLAN traffic over Ethernet ports.

You configure a port to belong to a VLAN by assigning a membership mode that specifies the kind of 
traffic the port carries and the number of VLANs to which it can belong. 

 lists the membership 

modes and membership and VTP characteristics.

Static-access

A static-access port can belong to one VLAN and is 
manually assigned to that VLAN. 

For more information, see the 

VTP is not required. If you do not want 
VTP to globally propagate information, set 
the VTP mode to transparent. To 
participate in VTP, there must be at least 
one trunk port on the switch connected to a 
trunk port of a second switch.

Trunk (ISL or 

 

IEEE 802.1Q) 

A trunk port is a member of all VLANs by default, 
including extended-range VLANs, but membership can be 
limited by configuring the allowed-VLAN list. You can 
also modify the pruning-eligible list to block flooded 
traffic to VLANs on trunk ports that are included in the 
list.

For information about configuring trunk ports, see the 

VTP is recommended but not required. 
VTP maintains VLAN configuration 
consistency by managing the addition, 
deletion, and renaming of VLANs on a 
network-wide basis. VTP exchanges 
VLAN configuration messages with other 
switches over trunk links.

Dynamic access

A dynamic-access port can belong to one VLAN (VLAN 
ID 1 to 4094) and is dynamically assigned by a VMPS. The 
VMPS can be a Catalyst 5000 or Catalyst 6500 series 
switch, for example, but never a Catalyst 3560 switch. The 
Catalyst 3560 switch is a VMPS client.

You can have dynamic-access ports and trunk ports on the 
same switch, but you must connect the dynamic-access 
port to an end station or hub and not to another switch.

For configuration information, see the 

.

VTP is required. 

Configure the VMPS and the client with 
the same VTP domain name. 

To participate in VTP, at least one trunk 
port on the switch must be connected to a 
trunk port of a second switch.
