ProSafe Managed Switch The port identifies the specific physical port or logical interface being managed on a given slot. Table 4. Type of Ports Port Type Physical Ports Logical Interfaces CPU ports Description The physical ports for each slot are numbered sequentially starting from zero. Port-channel or Link Aggregation Group (LAG) interfaces are logical interfaces that are only used for bridging functions. VLAN routing interfaces are only used for routing functions. Loopback interfaces are logical interfaces that are always up. Tunnel interfaces are logical point-to-point links that carry encapsulated packets. CPU ports are handled by the driver as one or more physical entities located on physical slots. Note: In the CLI, loopback and tunnel interfaces do not use the unit/slot/port format. To specify a loopback interface, you use the loopback ID. To specify a tunnel interface, you use the tunnel ID. Using a Command's "No" Form The no keyword is a specific form of an existing command and does not represent a new or distinct command. Almost every configuration command has a no form. In general, use the no form to reverse the action of a command or reset a value back to the default. For example, the no shutdown configuration command reverses the shutdown of an interface. Use the command without the keyword no to re-enable a disabled feature or to enable a feature that is disabled by default. Only the configuration commands are available in the no form. Managed Switch Modules Managed switch software consists of flexible modules that can be applied in various combinations to develop advanced Layer 2/3/4+ products. The commands and command modes available on your switch depend on the installed modules. Additionally, for some show commands, the output fields might change based on the modules included in the software. The software suite includes the following modules: • Switching (Layer 2) • Routing (Layer 3) • IPv6-IPv6 routing • Multicast Using the Command-Line Interface 13
