Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and processor modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.

Token Ring Overview
The following sections describe Token Ring specifications, physical connections, connection equipment, and cables and connectors.
Token Ring Specifications
The term Token Ring refers to both IBM's Token Ring Network, which IBM developed in the 1970s, and to IEEE 802.5 networks. The IEEE 802.5 specification was modeled after, and still closely shadows, IBM's network. The two types are compatible, although the specifications differ slightly.
Token Ring and IEEE 802.5 are token passing networks, which move a small frame, called a token, around the network. Possession of the token grants the right to transmit; a station with information to transmit must wait until it detects a free token passing by.
The IBM Token Ring specifies a star topology, with all end stations connected through a device called a multistation access unit (MSAU). IEEE 802.5 does not specify any topology, although most implementations are based on a star configuration with end stations attached to a device called a media access unit (MAU). Also, IBM Token Ring specifies twisted-pair cabling, whereas IEEE 802.5 does not specify media type. Most Token Ring networks use shielded twisted-pair cabling; however, some networks that operate at 4 Mbps use unshielded twisted-pair cable.
Table 1 shows a comparison of the two types.
Table 1 IBM Token Ring and IEEE 802.5 Comparison
All 4R port adapter interfaces support both 4- and 16-Mbps, half-duplex operation and early token release. The default for all ports is for 4-Mbps operation and early token release disabled. Both states are enabled with configuration commands in configuration mode.
To enable 16 Mbps, specify the slot/port address and use the configuration command ring-speed 16; to return to 4 Mbps operation, use the command ring-speed 4. To enable and disable early token release, specify the slot/port address and use the configuration command [no] early token release. For complete descriptions and examples of software commands, refer to the related software configuration documentation.
In the typical Token Ring network shown in Figure 1, lobe cables connect each Token Ring station (4R port adapter interface) to the MSAU (or MAU), and patch cables connect adjacent MSAUs (or MAUs) to form one large ring.
Figure 1 Token Ring Network Physical Connections
Token Ring Connection Equipment
You will need an 802.5 MAU or an MSAU to provide the interface between the 4R port adapter Token Ring interfaces and the external ring, and a Token Ring lobe cable between each 4R port adapter interface and the MAU or MSAU. Lobe cables connect each Token Ring station (4R port adapter interface) to the MAU or MSAU, and patch cables can connect adjacent MSAUs to form one large ring.
4R port adapter interfaces operate at either 4 or 16 Mbps. The default speed for all 4R port adapter interfaces is 4 Mbps, which you can change to 16 Mbps on any port using the ring-speed n configuration command, where n is the speed (4 or 16) in Mbps. The speed of each Token Ring port must match the speed of the ring to which it is connected. Before you enable the Token Ring interfaces, ensure that each is set for the correct speed, or it can bring down the ring.
Caution
Token Ring Distance Limitations
The maximum transmission distance is not defined for IEEE 802.5 (Token Ring) networks. Shielded twisted-pair (STP) cabling is most commonly used for rates of 4 and 16 Mbps. Twisted-pair cabling is more susceptible to interference than other types of cabling; therefore, the network length and repeater spacing should be planned accordingly.
Token Ring Speed Considerations
Before you install the 4R port adapter, determine the ring speed (4 or 16 Mbps) of each ring to be connected to the server. There is no factory default for the interface speed; you must set the speed of each interface (within the setup command facility or with the ring-speed command) before you bring the interface up and insert it into the ring with the no shutdown command.
Caution
What Is the 4R Port Adapter?
The following sections provide additional information specific to the 4R port adapter:
•
•
The 4R port adapter (see ) provides up to four IBM Token Ring or IEEE 802.5 Token Ring interfaces. Each Token Ring interface can be set for 4 Mbps or 16 Mbps. All Token Ring ports on PA-4R are half duplex (only) and run at wire speed.
Figure 2 4R Port Adapter (Faceplate View)
The 4R port adapter can be installed on the VIP2 in port adapter slot 0 and port adapter slot 1, or in the Cisco 7200 series routers in any of the chassis' port adapter slots: slot 1 and slot 2 of the Cisco 7202, slots 1 through 4 of the Cisco 7204,and slots 1 through 6 of the Cisco 7206..
Port Adapter Locations on the VIP2 and the Cisco 7200 Series Router
This section provides information about where you can install the 4R port adapter on the VIP2 and in the Cisco 7200 series routers.
Note
shows a VIP2-15 or VIP2-40 with two installed port adapters. With the VIP2 oriented as shown, the left port adapter is in port adapter slot 0, and the right port adapter is in port adapter slot 1.
Figure 3 Two Port Adapters on the VIP2-15 or VIP2-40 (Horizontal Orientation Shown)
Note
In the Cisco 7200 series routers, port adapter slots are numbered from the lower left to the upper right, beginning with port adapter slot 1 and continuing through port adapter slot 2 for the Cisco 7202, slot 4 for the Cisco 7204, and slot 6 for the Cisco 7206. Port adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller.
Note
Figure 4 shows a Cisco 7206 with installed port adapters and an I/O controller with a Fast Ethernet port. Not shown are the Cisco 7202, which has two port adapter slots, and the Cisco 7204, which has four port adapter slots. The 4R-FDX port adapter can be installed in any available port adapter slot in the Cisco 7200 series routers.
Figure 4 Port Adapters in the Cisco 7206
4R Port Adapter LEDs
The 4R port adapter has several LEDs that indicate status of the port adapter and its interfaces. After system initialization, the enabled LED goes on to indicate that the 4R port adapter has been enabled for operation. (The LEDs are shown in .)
Figure 5 4R Port Adapter LEDs (Partial Faceplate View)
The following conditions must be met before the enabled LED goes on:
•
•
•
If any of these conditions is not met, or if the initialization fails for other reasons, the port adapter's enabled LED does not go on.
When a Token Ring interface is configured by using software commands, the In Ring and 4/16 Mbps LEDs (shown in ) indicate the following for each port:
•
•
4R Port Adapter Receptacles, Cables, and Pinouts
A network interface cable provides the connection between the 9-pin Token Ring receptacles on the 4R port adapter and a media access unit (MAU). The 9-pin connector at the 4R port adapter end and the MAU connector at the network end are described in the section "Token Ring Connection Equipment" on page 8.
4R Port Adapter Cables
The Token Ring ports on the 4R port adapter are DB-9 (PC type) receptacles that require Type 1 or Type 3 lobe cables. Token Ring interface cables are not available from Cisco Systems, but are commercially available through outside cable vendors.
Type 1 lobe cables use shielded twisted-pair (STP) cable and terminate at the network end with a large MAU plug. (See Figure 6.) The 4R port adapter end of the cable is a DB-9 plug.
Figure 6 Token Ring Type 1 Lobe Cable Connectors (DB-9 and MAU Types)
Type 3 lobe cables use either shielded or unshielded twisted-pair (UTP) cable and terminate at the network end with an RJ-11 plug. (See .) The 4R port adapter end of the cable is a DB-9 plug.

The 4R port adapter can be installed in either port adapter slot 0 or port adapter slot 1 on the VIP2. shows a 4R port adapter installed in port adapter slot 0, on a VIP2-15 or VIP2-40.
Figure 8 VIP2-15 or VIP2-40 with a 4R Port Adapter in Port Adapter Slot 0
Port adapters have a handle attached, but this handle is not shown to allow a full view of detail on each port adapter's faceplate.
Installing or Replacing a Port Adapter on a VIP2
Depending on the circumstances, you might need to install a new port adapter on a VIP2 motherboard or replace a failed port adapter in the field. In either case, you need a number 1 Phillips screwdriver, an antistatic mat onto which you can place the removed interface processor, and an antistatic container into which you can place a failed port adapter for shipment back to the factory.
Caution
Note
While the VIP2 supports online insertion and removal, individual port adapters do not. To replace port adapters, you must first remove the VIP2 from the chassis, then install or replace port adapters as required. If a blank port adapter is installed on the VIP2 in which you want to install a new port adapter, you must first remove the VIP2 from the chassis, then remove the blank port adapter.
Caution
When only one port adapter is installed on a VIP2, a blank port adapter must fill the empty slot to allow the VIP2 and router chassis to conform to electromagnetic interference (EMI) emissions requirements, and so that air flows through the chassis properly. If you plan to install a new port adapter, you must first remove the blank port adapter.
Use the following standard procedure to remove and replace any type of port adapter on a VIP2:

Attaching 4R Port Adapter Interface Cables
The Token Ring ports on the 4R port adapter run at either 4- or 16 Mbps. You need one Token Ring interface cable for each 4R port adapter interface you want to use. Token Ring interface cables are not available from Cisco Systems, but are commercially available through outside cable vendors. Port adapters have a handle attached (see ), but this handle is not shown in to allow a full view of detail on the 4R port adapter's faceplate.
Use the following procedure to attach Token Ring cables to the 4R port adapter:

Step 3
This completes the procedure for attaching interface cables to the 4R port adapter.
Configuring the 4R Interfaces
The following procedures describe basic configuration information for the 4R port adapter. If you installed a new 4R port adapter or if you want to change the configuration of an existing interface, you must enter configuration mode using the configure command. If you replaced a 4R port adapter that was previously configured, the system will recognize the new 4R interfaces and bring them up in their existing configuration.
After you verify that the new 4R port adapter is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interfaces. Be prepared with the information you will need, such as the following:
•
•
•
Note
For a summary of the configuration options available and instructions for configuring the 4R interfaces on the VIP2, refer to the appropriate configuration publications listed in the section "If You Need More Information" on page 2.
Determining Chassis Slot, Port Adapter, and Token Ring Interface Port Numbers
The following section describes how to identify chassis slot, port adapter, and Token Ring interface port numbers.
Note
In the router, physical port addresses specify the actual physical location of each interface port on the router interface processor end. (See .) This address is composed of a three-part number in the format chassis slot number/port adapter number/interface port number, as follows:
•
•
•
Interface ports on the 4R port adapter maintain the same address regardless of whether other interface processors are installed or removed. However, when you move a VIP2 to a different slot, the first number in the address changes to reflect the new slot number.
shows some of the slot port adapter and interface ports of a sample Cisco 7505 system. The first port adapter slot number is always 0. The second port adapter slot number is always 1. The individual interface port numbers always begin with 0. The number of additional ports depends on the number of ports on a port adapter.
For example, the addresses for the 4R interface ports on the first port adapter on a VIP2 (see ) are 3/0/0 through 3/0/3 (chassis slot 3, port adapter slot 0, and interface ports 0 through 3). If the 4R port adapter were installed in port adapter slot 1, the interface addresses would be 3/1/0 through 3/1/3.
Note
Figure 14 4R Token Ring Interface Port Number Example (Cisco 7505 Shown)
You can identify interface ports by physically checking the slot/port adapter/interface port location on the back of the router or by using software commands to display information about a specific interface or all interfaces in the router.
Using the EXEC Command Interpreter
You can modify the startup configuration for Cisco 7500 series routers through the software command interpreter called EXEC. To configure the interfaces for interface processors, you can use either one of the setup or configure EXEC commands.
The setup command facility can be used after first time startup to make basic changes at any time. The changes you make will affect only the changed elements' current memory values that are stored in nonvolatile memory.
The configure privileged EXEC command enables you to perform advanced configurations such as specifying interfaces. The EXEC interprets the commands you enter and carries out the corresponding operations. You can list available EXEC commands by entering a question mark (?). You also can enter a question mark to obtain more information about commands. For example, enter terminal ? to obtain a list of terminal commands or show ? to obtain a list of show commands.
Before you use the setup or the configure command, you must have privileged access to the EXEC command interpreter. The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). The EXEC enable command allows access to the privileged level, prompting for a password if one has been set with the enable-password configuration command.
Follow these steps to enter the privileged level of the EXEC.
Step 1
Router> enableThe EXEC prompts you for a privileged level password:Password:Step 2
For security purposes, the password is not displayed. (Also note that the password is case sensitive). When you enter the correct password, the system displays the privileged mode system prompt:
Router#
To configure Token Ring interfaces using the setup EXEC command facility, follow the instructions in the section "Using the Setup Command Facility." To configure the Token Ring interfaces by using the configure EXEC command, follow the instructions in the section "Determining Chassis Slot, Port Adapter, and Token Ring Interface Port Numbers" on page 19.
Using the Setup Command Facility
The setup command facility identifies all interfaces (including the Token Ring interfaces for the ports on the 4R port adapter) that are installed and prompts you for configuration information for each installed interface. When you finish configuring one interface, the setup command facility prompts you for the next, continuing until each interface has been configured.
When you enter the setup command facility after first time startup, you must run through the entire dialog until you come to the interface you want to change. Note that when you use the setup command after first time startup, the default values indicated within the brackets in the System Configuration Dialog are the values last set using the setup command facility or left as defaults.
After you choose to continue with the setup command (by answering yes to the system configuration dialog prompt), the remainder of the script is the actual configuration process. The dialog prompts you first for global system parameters, then for configuration information for each interface. The existing configuration is displayed as the default, in brackets ([ ]), at the end of each prompt. Press Return to accept the default settings.
Note
Use the setup command facility to configure the 4R Token Ring interfaces, as follows:
Step 1
Router# setupStep 2
-System Configuration Dialog- At any point you may enter a question mark `?' for help. Refer to the `Getting Started' Guide for additional help. Default settings are in square brackets `[]'. Continue with configuration dialog? [yes]:(Use Ctrl-c to abort configuration at any prompt) Configuring global parameters: Enter host name [Router]: sandboxStep 3
Step 4
After the global parameters are configured, the system prompts you for interface configuration information, one interface at a time. Following is a partial display of the script for a previously configured interface:
Configuring interface parameters: Configuring interface Token Ring0: Is this interface in use [yes]: Tokenring ring speed (4 or 16) [16] Configure IP on this interface? [yes]: IP address for this interface: 1.1.1.30 (remainder of display text omitted)
Caution
Step 5
When all interfaces are configured, the system displays the entire configuration script followed by a prompt for which there is no default (you must enter yes or no):
Use this configuration [yes/no]:Step 6
If you entered yes at the prompt, the following message is displayed:
Press RETURN to get started!
The configuration process is complete. Proceed to the section "Checking the Configuration" on page 24. It provides show commands you can use to display and verify the configuration information.
Configuring Interfaces Using the configure Command
Following are instructions for a basic configuration using the configure command: enabling an interface, setting interface ring speed, and specifying IP routing. You might also need to enter other configuration subcommands depending upon the requirements for your system configuration. Press the Return key after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by entering disable at the prompt as follows:
Router# disableRouter>Use the following procedure to perform a basic configuration:
Step 1
Router# configure terminalEnter configuration commands, one per line. End with CNTL/Z.Step 2
Router(config)# interface tokenring 3/0/0Step 3
Router(config-if)# ip address ip address subnet mask
Caution
Note
Step 4
Router(config-if)# no shutdownWhen you enable the interface by using the no shutdown command, the LED for 4 Mbps or 16 Mbps is turned on after about 5 seconds. The In Ring LED for that interface is turned on about 5 to 18 seconds later, when the port is initialized and connected to the ring.
Step 5
Router(config-if)# ring-speed 16Step 6
Step 7
Step 8
Step 9
Router# copy running-config startup-config[OK]Router#Step 10
Router# quit
You have now completed configuring the Token Ring interfaces. Check the configuration as described in the section "Checking the Configuration."
Checking the Configuration
After configuring the new interface, use the show commands to display the status of the new interface or all interfaces and the ping command to check connectivity. Refer to the publications listed in the section "If You Need More Information" on page 2, for detailed command descriptions and examples.
Using show Commands to Verify the VIP2 Status
After configuring the new interface(s) using either the setup command or the configure command, use the EXEC show commands to display status information.
Step 1
Step 2
Router# show configurationThe configuration file for the router is displayed. Check the Token Ring configuration information in the display.
Step 3
Router# show interfacesEach interface is listed along with its assigned IP address. Verify that each new Token Ring interface appears.
Step 4
Router# show interface tokenring slot/port adapter/portDetailed information about the interface is displayed. The first line of display specifies the interface along with its slot and port number. It indicates whether the hardware is functional and if the line protocol is up or down. If the line protocol is down (and you did not administratively shut it down), or if the hardware is not functioning properly, ensure that the network interface is properly connected and terminated. (For explanations of the displayed information, refer to publications listed in the section "If You Need More Information," on page 2, which are available on the Documentation CD-ROM.)
Step 5
Router# show controllers token
The display lists the Token Ring interfaces connected to each VIP2 and indicates whether the system has identified your new interface. It does not indicate the state of the line or the protocol.
To display information about a specific interface, use the show interfaces command with the interface type and port address in the format show interfaces [type slot/port adapter/port].
Following is an example of how the show interfaces [type slot/port adapter/port] command displays status information (including the physical slot and port address) for the interfaces you specify. In these examples, most of the status information for each interface is omitted, and the four Token Ring interfaces (0-3) are in chassis slot 3, in port adapter slot 0. (Interfaces are administratively shut down until you enable them.)

The ping command allows you to verify that an interface port is functioning properly and to check the path between a specific port and connected devices at various locations on the network. This section provides brief descriptions of the ping command. After you verify that the system and VIP2 have booted successfully and are operational, you can use this command to verify the status of interface ports.
The ping command sends an echo request out to a remote device at an IP address that you specify. After sending a series of signals, the command waits a specified time for the remote device to echo the signals. Each returned signal is displayed as an exclamation point (!) on the console terminal; each signal that is not returned before the specified time-out is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate that the connection failed.

Installing or Replacing a Port Adapter in Cisco 7200 Series Routers
This section provides the standard procedures for installing or replacing port adapters in a Cisco 7200 series router.
Depending on your circumstances, you might need to install a new port adapter in a Cisco 7200 series router or replace a failed port adapter in the field. In either case no tools are necessary; all port adapters available for the Cisco 7200 series connect directly to the router midplane and are locked into position by a port adapter lever. When removing and replacing a port adapter, you will need an antistatic mat onto which you can place a removed port adapter and an antistatic container into which you can place a failed port adapter for shipment back to the factory.
Note
When a port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router to conform to EMI emissions requirements and to allow proper air flow across the port adapters. If you plan to install a new port adapter in a slot that is not in use, you must first remove a blank port adapter.
Removing a Port Adapter

Attaching 4R Port Adapter Interface Cables
The Token Ring ports on the 4R port adapter run at either 4 or 16 Mbps. You need one Token Ring interface cable for each 4R port adapter interface you want to use. Token Ring interface cables are not available from Cisco Systems, but are commercially available through outside cable vendors. Port adapters have a handle but this handle is not shown in to allow a full view of detail on the 4R port adapter's faceplate.
Use the following procedure to attach Token Ring cables to the 4R port adapter:

This completes the procedure for attaching 4R port adapter interface cables.
Configuring the 4R Interfaces
The following procedures describe basic configuration information for the 4R port adapter. If you installed a new 4R port adapter or if you want to change the configuration of an existing interface, you must enter configuration mode using the configure command. If you replaced a 4R port adapter that was previously configured, the system will recognize the new 4R interfaces and bring them up in their existing configuration.
After you verify that the new 4R port adapter is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interfaces. Be prepared with the information you will need, such as the following:
•
•
•
Note
For a summary of the configuration options available and instructions for configuring the 4R interfaces on the Cisco 7206, refer to the appropriate configuration publications listed in the section "If You Need More Information" on page 2.
Selecting Port Adapter Slot and Token Ring Interface Port Numbers
The following section describes how to identify port adapter slot and Token Ring interface port numbers. In the router, physical port addresses specify the actual physical location of each interface port on the router. (See .) This address is composed of a two-part number in the format port adapter slot number/interface port number, as follows:
•
The second number identifies interface ports on each 4R port adapter and are always numbered in sequence as interface 0 through 3.
Interface ports on the 4R port adapter 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 address changes to reflect the new slot number.
In the Cisco 7200 series routers, port adapter slots are numbered from the lower left to the upper right, beginning with port adapter slot 1 and continuing through port adapter slot 2 for the Cisco 7202, slot 4 for the Cisco 7204, and slot 6 for the Cisco 7206. Port adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller—if present. Figure 21 shows the port adapter slots and interface ports of a Cisco 7206.
Note
The individual interface port numbers always begin with 0. The number of additional ports depends on the number of ports on a port adapter. For example, the addresses of the interface ports on the 4R port adapter in slot 6 are 6/0 through 6/3 (chassis slot 6 and interface ports 0 through 3). If the 4R port adapter were installed in port adapter slot 4, the interface addresses would be 4/0 through 4/3.
Figure 21 4R Token Ring Interface Port Number Example
You can also identify interface ports by physically checking the slot/interface port location on the back of the router or by using software commands to display information about a specific interface or all interfaces in the router.
Configuring Interfaces
Following are instructions for a basic interface configuration using the configure command: enabling an interface, setting interface ring speed, and specifying IP routing. You might also need to enter other configuration subcommands depending upon the requirements for your system configuration. Press the Return key after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by entering disable at the prompt as follows:
Router# disableRouter>Use the following procedure to perform a basic configuration:
Step 1
Router# configure terminalEnter configuration commands, one per line. End with CNTL/Z.Step 2
Router(config)# interface tokenring 6/0Step 3
Router(config-if)# ip address 1.1.1.10 255.255.255.0
Caution
Note
Step 4
Router(config-if)# no shutdownWhen you enable the interface by using the no shutdown command, the LED for 4 Mbps or 16 Mbps is turned on after about 5 seconds. The In Ring LED for that interface is turned on about 5 to 18 seconds later, when the port is initialized and connected to the ring.
Step 5
Router(config-if)# ring-speed 16Step 6
Step 7
Step 8
Step 9
Router# copy running-config startup-config[OK]Router#
To check the interface configuration using show commands, proceed to the section "Checking the Configuration."
Checking the Configuration
After configuring the new interface, use the show commands to display the status of the new interface or all interfaces and use the ping command to check connectivity.
Using show Commands to Verify the New Interface Status
The following steps use show commands to verify that the new interfaces are configured and operating correctly.
Step 1
Step 2
Step 3
Step 4
Step 5
If the interface is down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the network interface is properly connected and terminated. If you still have problems bringing the interface up, contact a service representative for assistance.
Using show Commands to Display Interface Information
To display information about a specific interface, use the show interfaces command with the interface type and port address in the format show interfaces [type slot/port].
Following is an example of how the show interfaces [type slot/port] command displays status information (including the physical slot and port address) for the interfaces you specify. In these examples, most of the status information for each interface is omitted, and the four Token Ring interfaces (0-3) are in port adapter slot 6. (Interfaces are administratively shut down until you enable them.)

Using the ping Command
The ping command allows you to verify that an interface port is functioning properly and to check the path between a specific port and connected devices at various locations on the network. This section provides brief descriptions of the ping command. After you verify that the system has booted successfully and is operational, you can use this command to verify the status of interface ports. Refer to the publications listed in the section "If You Need More Information" on page 2, for detailed command descriptions and examples.
The ping command sends an echo request out to a remote device at an IP address that you specify. After sending a series of signals, the command waits a specified time for the remote device to echo the signals. Each returned signal is displayed as an exclamation point (!) on the console terminal; each signal that is not returned before the specified time-out is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate that the connection failed.
Following is an example of a successful ping command to a remote server with the address 1.1.1.10:
Router# ping 1.1.1.10 <Return>Type escape sequence to abort.Sending 5, 100-byte ICMP Echoes to 1.1.1.10, timeout is 2 seconds:!!!!!Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 msRouter#If the connection fails, verify that you have the correct IP address for the server and that the server is active (powered on), and repeat the ping command.For complete descriptions of interface subcommands and the configuration options available for Cisco 7206-related interfaces and functionality, refer to the publications listed in the section "If You Need More Information" on page 2.
