Port Addresses
Each port (or interface) in the Cisco 7600 series router is designated by several different types of addresses. The physical interface address is the actual physical location (slot and port) of the interface connector within the chassis. The system software uses the physical addresses to control activity within the system and to display status information. These physical slot and port addresses are not used by other devices in the network; they are specific to the individual router and its internal components and software. For more information, see the "Physical Interface Addresses" section.
The MAC address is a standardized data link layer address that is required for every port or device that connects to a network. Other devices in the network use these addresses to locate specific ports in the network and to create and update routing tables and data structures. The routers use a unique method, described in the "MAC Addresses" section, to assign and control the MAC addresses of their interfaces.
Physical Interface Addresses
Physical port addresses specify the actual physical location of each module port on the rear of the router, as shown in Figure 1-41. (The port numbering convention is the same in the three-slot, four-slot, six-slot, nine-slot, and thirteen-slot chassis.) The address is a two-part number in the format slot/port number. The first number identifies the slot in which the module is installed. Module slots are numbered from right to left starting with 1. The second number identifies the physical port number on the module. The port numbers always begin at 1 and are numbered from top to bottom. The number of additional ports (n/1, n/2, and so on) depends on the number of ports on the module.
Figure 1-41 Cisco 7609 Router Port Address Examples
Interface ports maintain the same address regardless of whether other modules are installed or removed. However, when you move a module to a different slot, the first number in the address changes to reflect the new slot number. For example, on a 4-port OC-12c POS OSM in slot 4 of the Cisco 7609 router, the address of the top WAN port is 4/1, and the address of the bottom WAN port is 4/4. If you remove the 4-port OC-12c POS OSM from slot 4 and install it in slot 7, the addresses of those same WAN ports become 7/1 through 7/4.
You can identify module ports by checking the slot and port location on the router. You can also use software commands to display information about a specific interface, or all interfaces, in the system. To display information about every interface, enter the show interfaces command without parameters. To display information about a specific interface, enter the show interfaces type command (type being the interface type) with the module (slot) number and port number in the format show interfaces type [mod/port].
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 gives the router the intelligence to identify the state (connected or not connected) of each interface. When you hot swap a module, the MAC address changes with the module.
Hot Swapping Supervisor Engines and Modules
The Cisco 7600 series routers provide a feature for removing and replacing the redundant supervisor engine, OSMs, Catalyst 6000 family modules, and SIPS without powering down the system. This feature is known as hot swapping.
Note
When you remove or insert a module while the router is powered on and operating, the system does the following:
1.
2.
3.
4.
The system runs diagnostic tests on any new interfaces. If the test passes, the system is operating normally. If the new module is faulty, the system resumes normal operation but leaves the new interface disabled.
If the diagnostic test fails, the system crashes, which usually indicates that the new module has a problem in the bus and should be removed.
When you install two supervisor engines, hot swapping allows you to remove and replace one of the supervisor engines without turning off the system power.

OSM Technology Overview
This section provides an overview of SONET/SDH and ATM:
SONET/SDH Overview
The Packet over SONET (POS) specification defines the use of PPP encapsulation over SONET/Synchronous Digital Hierarchy (SDH) links. SONET is an ANSI standard (T1.1051988) for optical digital transmission at hierarchical rates from 51.840 Mbps (STS-1) to 2.5 Gbps (STS-48) and greater. SDH is the international standard for optical digital transmission at hierarchical rates from 155.520 Mbps (STM-1) to 2.5 Gbps (STM-16) and greater.
Because a SONET/SDH link is considered to be a point-to-point circuit, PPP is well-suited for use over these links. PPP was designed as a standard method of communicating over point-to-point links.
SONET is an octet-synchronous multiplex scheme that defines a family of standard rates and formats. The basic rate for POS is STS-3c/STM-1, which is 155.520 Mbps. The available information bandwidth is 149.760 Mbps, which is the STS-3c/STM-1 Synchronous Payload Envelope (SPE), the payload portion of the SONET frame into which the octet-oriented user data is mapped. (Octet boundaries are aligned with the SPE octet boundaries.)
The International Telecommunications Union Telecommunication Sector (ITU-T) defines a series of SDH transmission rates beginning at 155.520 Mbps as follows:
STS-3c
STM-1
STS-12c
STM-4c
STS-48c
STM-16c
1 ANSI-defined SONET specifications.
SONET is not limited to optical links. Electrical specifications have been defined for single-mode fiber, multimode fiber, and CATV 75-ohm coaxial cable. OSMs currently allow transmission only over single-mode and multimode optical fiber. Transmission rates are integral multiples of 51.840 Mbps, which can be used to carry T3/E3 bit-synchronous signals.
The following transmission multiples are currently specified and commonly used:
•

ATM Overview
ATM uses cell-switching and multiplexing technology that combines the features of circuit switching (constant transmission delay and guaranteed capacity) with the features of packet switching (flexibility and efficiency for intermittent traffic).
ATM is a connection-oriented environment. All traffic to or from an ATM network is prefaced with a virtual path identifier (VPI) and virtual channel identifier (VCI). A VPI/VCI pair is considered a single virtual circuit. Each virtual circuit is a private connection to another node on the ATM network. Each virtual circuit is treated as a point-to-point mechanism to another router or host and is capable of supporting bidirectional traffic.
Each ATM node is required to establish a separate connection to every other node in the ATM network that it must communicate with. All of these connections are established using a permanent virtual circuit (PVC), which a network operator configures, or a switched virtual circuit (SVC), which is set up and torn down with an ATM signaling mechanism. This signaling is based on the ATM Forum User-Network Interface (UNI) Specification V3.x, 4.0.
