Managed Switch CLI Manual, Release 8.0 The slot number has two uses. In the case of physical ports, it identifies the card containing the ports. In the case of logical and CPU ports it also identifies the type of interface or port. Table 3. Type of Slots Slot Type Physical slot numbers Logical slot numbers CPU slot numbers Description Physical slot numbers begin with zero, and are allocated up to the maximum number of physical slots. Logical slots immediately follow physical slots and identify port-channel (LAG) or router interfaces. The CPU slots immediately follow the logical slots. 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.
