Port Adapter Overview

The PA-T3+ port adapter is a single-width, one port or two-port port adapter that provides full-duplex operation at T3 (45 Mbps) speed.

You can install one PA-T3+ or PA-2T3+ port adapter in a single width port adapter slot and one or two PA-T3+ or PA-2T3+ port adapters per FlexWAN module or VIP.

The one-port PA-T3+, shown in Figure 1-1, provides up to two network interfaces per Catalyst 6000 family FlexWAN module in the Catalyst 6000 family switches and VIP for Cisco 7000 series and Cisco 7500 series routers, and one interface on the Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco 7201 router, Cisco 7301 router, Cisco 7401ASR router, and Cisco 7304 PCI Port Adapter Carrier Card in the Cisco 7304 router.

The two-port PA-2T3+, shown in Figure 1-2, provides up to four network interfaces per Catalyst 6000 family FlexWAN module in the Catalyst 6000 family switches and VIP for Cisco 7000 series and Cisco 7500 series routers, and two interfaces on the Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco 7201 router, Cisco 7301 router, Cisco 7401ASR router, and Cisco 7304 PCI Port Adapter Carrier Card in the Cisco 7304 router.

The port adapters both support 16- and 32-bit cyclic redundancy checks (CRCs). The default is 16-bit CRCs; to enable 32-bit CRCs, you use a configuration command. For a description of the CRC function, see the "Configuring Cyclic Redundancy Checks" section

Cables and Connectors

The PA-T3+ serial interface cable, which is a 75-ohm coaxial cable, is used to connect your router to a T3+ serial network. The serial ports on the PA-T3+ are considered to be DTE devices.

The PA-T3+ has one or two T3+ serial ports, each with two connectors (receive and transmit) to which you connect the Cisco 75-ohm coaxial cable. The 75-ohm coaxial cable (Product Number CAB-ATM-DS3/E3=) for the T3+ serial port adapter is available only from Cisco Systems; it is not available from outside commercial cable vendors.

The Cisco T3+ 75-ohm coaxial cable (see Figure 1-5) is available only in 10-foot (3.05-meter) lengths. The typical maximum distance between stations for T3+ transmissions is up to 450 feet for 734A or equivalent coaxial cable, or up to 225 feet for 728A or equivalent coaxial cable.

Figure 1-5 T3+ Serial Port Adapter Cables

You can test the DTE-to-DCE cable connection by using the loopback dte command. See the "Using loopback Commands" section, for more information.

Management Information Base

Management Information Base (MIB) attributes are readable and writable across ILMI through use of the SNMP.

The one-port PA-T3+ supports all MIB-II (RFC 1213) and the DS3 interface MIB (RFC 1407).

The two-port PA-2T3+ supports MIB-II (RFC 1213) and the DS3 interface MIB (RFC 1407).

Identifying Interface Addresses

This section describes how to identify interface addresses for the PA-T3+ in supported platforms. Interface addresses specify the actual physical location of each interface on a router or switch.

Interfaces on a PA-T3+ installed in a router maintain the same address regardless of whether other port adapters are installed or removed. However, when you move a port adapter to a different slot, the first number in the interface address changes to reflect the new port adapter slot number.

Interfaces on a PA-T3+ installed in a FlexWAN module or a VIP maintain the same address regardless of whether other modules or interface processors are installed or removed. However, when you move a FlexWAN module or a VIP to a different slot, the module or interface processor slot number changes to reflect the new module or interface processor slot.


Note Interface ports are numbered from left to right starting with 0.


The following subsections describe the interface address formats for the supported platforms:

Catalyst 6000 Family FlexWAN Module Interface Addresses

In Catalyst 6000 family switches, the Catalyst 6000 family FlexWAN module can be installed in module slots 2 through 13 (depending on the number of slots in the router). Slot 1 is reserved for the supervisor engine. A port adapter can be installed into either port adapter bay 0 or bay 1 on a FlexWAN module. See Figure 1-6.

The interface address is composed of a three-part number in the format module-number/port-adapter-bay-number/interface-port-number. See Table 1-3.

The first number identifies the module slot of the chassis in which the FlexWAN module is installed (slot 2 through slot 3, 6, 9, or 13 depending on the number of slots in the chassis). These module slots are generally numbered from top to bottom, starting with 1.

The second number identifies the bay of the FlexWAN module in which the port adapter is installed (0 or 1). The bays are numbered from left to right on the FlexWAN module.

The third number identifies the physical port number on the port adapter. The PA-T3+ is a single-port port adapter, therefore the port number is always 0. The PA-2T3+ is a dual-port port adapter, therefore the port can be 0 or 1.

For example, if a single-port PA-T3+ is installed in a FlexWAN module in module slot 3, port adapter bay 0, then the interface address is 3/0/0 (module slot 3, port adapter bay 0, and interfaces 0). I f a dual-port PA-2T3+ is installed in a FlexWAN module in module slot 3, port adapter bay 0, then the interface addresses are 3/0/0 and 3/0/1 (module slot 3, port adapter bay 0, and interfaces 0 and 1).


Note The FlexWAN module physical port address begins with slot 0, which differs from the conventional Catalyst 6000 family port address, which begins with slot 1.


Cisco 7200 Series Routers and Cisco 7200 VXR Routers Interface Addresses

In Cisco 7200 series routers and Cisco 7200 VXR routers, port adapter slots are numbered from the lower left to the upper right, beginning with slot 1 and continuing through slot 2 for the Cisco 7202, slot 4 for the Cisco 7204 and Cisco 7204VXR, and slot 6 for the Cisco 7206 and Cisco 7206VXR. Port adapters can be installed in any available port adapter slot from 1 through 6 (depending on the number of slots in the router). (Slot 0 is reserved for the I/O controller.) See Figure 1-7.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-3. For example, if a single-port PA-T3+ is installed in slot 1of a Cisco 7200 series router, the interface address would be 1/0. If a dual-port PA-2T3+ were installed in slot 1, the interface addresses would be 1/0 and 1/1.

Cisco 7201 Router Interface Addresses

In the Cisco 7201 router, only one slot accepts port adapters and it is numbered as slot 1. See Figure 1-8.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-3. For example, if a single-port PA-T3+ is installed in a Cisco 7201 router, the interface address would be 1/0. If a dual-port PA-2T3+ is installed in a Cisco 7201 router, the interface addresses would be 1/0 and 1/1.

Cisco 7301 Router Interface Addresses

In the Cisco 7201 router, only one slot accepts port adapters and it is numbered as slot 1. See Figure 1-9.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-3. For example, if a single-port PA-T3+ is installed in a Cisco 7201 router, the interface address would be 1/0. If a dual-port PA-2T3+ is installed in a Cisco 7201 router, the interface addresses would be 1/0 and 1/1.

Cisco 7304 PCI Port Adapter Carrier Card Interface Addresses

In the Cisco 7304 router, port adapters are installed in a Cisco 7304 PCI port adapter carrier card, which installs in Cisco 7304 router module slots 2 through 5. The port adapter slot number is the same as the module slot number. See Figure 1-11.

The interface address is composed of a two-part number in the format module-slot-number/interface-port-number. See Table 1-3. For example, if a single-port PA-T3+ is installed in the Cisco 7304 PCI port adapter carrier card in Cisco 7304 router module slot 3, the interface address would be 3/0. If a dual-port PA-2T3+ is installed in the Cisco 7304 PCI port adapter carrier card in Cisco 7304 router module slot 3, the interface addresses would be 3/0 and 3/1.

Cisco 7401ASR Router Interface Addresses

In the Cisco 7201 router, only one slot accepts port adapters and it is numbered as slot 1. See Figure 1-12.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-3. For example, if a single-port PA-T3+ is installed in a Cisco 7201 router, the interface address would be 1/0. If a dual-port PA-2T3+ is installed in a Cisco 7201 router, the interface addresses would be 1/0 and 1/1.

Cisco 7000 Series Routers and Cisco 7500 Series Routers VIP Interface Addresses

In Cisco 7000 series routers and Cisco 7500 series routers, port adapters are installed on a versatile interface processor (VIP), which installs in interface processor slots 0 through 12 (depending on the number of slots in the router). The port adapter can be installed in either bay (port adapter slot 0 or 1) on the VIP. See Figure 1-13, and Figure 1-14.

The interface address for the VIP is composed of a three-part number in the format interface-processor-slot-number/port-adapter-slot-number/interface-port-number. See Table 1-3.

The first number identifies the slot in which the VIP is installed (slot 0 through 12, depending on the number of slots in the router).

The second number identifies the bay (port adapter slot) on the VIP in which the port adapter is installed (0 or 1). The bays are numbered from left to right on the VIP.

The third number identifies the physical port number (interface port number) on the port adapter. The port numbers always begin at 0 and are numbered from left to right. The number of additional ports depends on the number of ports on the port adapter. The PA-T3+ is a single-port port adapter, therefore the port number is always 0. The PA-2T3+ is a dual-port port adapter, therefore the port can be 0 or 1.

For example, if a single-port PA-T3+ is installed in a VIP in interface processor slot 3, port adapter slot 1, the interface address would be 3/1/0 (interface processor slot 3, port adapter slot 1, and interface 0). If a dual-port PA-2T3+ is installed in a VIP in interface processor slot 3, port adapter slot 1, the interface addresses would be 3/1/0 and 3/1/1 (interface processor slot 3, port adapter slot 1, and interfaces 0 and 1).


Note Although the processor slots in the 7-slot Cisco 7000 and Cisco 7507 and the 13-slot Cisco 7513 and Cisco 7576 are vertically oriented and those in the 5-slot Cisco 7010 and Cisco 7505 are horizontally oriented, all Cisco 7000 series and Cisco 7500 series routers use the same method for slot and port numbering.
