The supervisor engine and route switch processor have two or more uplink ports (numbered n/1, n/2, and so on). The Supervisor Engine 32 (WS-SUP32-GE-3B) has nine uplink ports, numbered n/1 to n/9.

In some cases, a single port supports two different types of connectors (for example, Port 2 on the Supervisor Engine 720 supports a Gigabit Ethernet SFP module or a 10/100/1000-Mbps RJ-45 connector). However, only one of the two options can be active at a time.

MAC Addresses

All network interface connections (ports) require a unique MAC address. The MAC address of an interface is stored in electrically erasable programmable read-only memory (EEPROM) on a component that resides directly on the interface circuitry. The router system code reads the EEPROM for each interface in the system, learns the MAC addresses, and then initializes appropriate hardware and data structures. Each VLAN in the spanning tree has one unique MAC address. This addressing scheme enables the router to identify the state (connected or not connected) of each interface. When you hot swap a module, the MAC address changes with the module.
