Interfaces
Interfaces
You use the Interfaces tab on the Interfaces/VLANs page to view and manage the following types of
ports:
• Access ports—A switching port that is used to connect host machines or servers. An access port
belongs to and carries the traffic of only one VLAN. Traffic is received and sent in native formats
with no VLAN tagging.
• Trunk ports—A switching port operating at Layer 2 to carry the traffic of multiple VLANs. Traffic
is tagged with a VLAN number to differentiate traffic from each VLAN. A trunk port is used to
connect switches to switches or to connect switches to routers.
• Routed ports—A physical port that acts like a port on a router. A routed port is not associated with
a particular VLAN, and it behaves like a regular router interface. You can configure a routed port
with a Layer 3 routing protocol.
• Dynamic ports—A port that can change dynamically to a trunk port if the neighboring port is
configured as a trunk port.
• Unsupported ports—Ports on the Catalyst device that are not supported by Security Manager.
To display the Interfaces tab, select a Catalyst device in Device view, select Interfaces/VLANs from the
Policy selector, then click the Interfaces tab in the work area.
The following topics describe the actions you can perform when defining interfaces on Catalyst devices:

Creating or Editing Ports on Cisco Catalyst Switches and Cisco 7600 Series
Routers
You can create access ports, routed ports, or trunk ports on Cisco Catalyst Switches and Cisco 7600
Series Routers, with these restrictions:
• Each interface must have a name.
• You can associate an access port with only one VLAN.
• You can associate a trunk port with one or more VLANs.
