Overview
The Encryption Service Adapter (ESA) is a high-performance data encryption module that implements data encryption and authentication algorithms. The ESA attaches to the Peripheral Component Interconnect (PCI) connector on the Catalyst 4000 Access Gateway Module.
The ESA includes a public key math processor and a hardware random number generator. These features support public key cryptography for key generation, exchange, and authentication. The ESA can encrypt and authenticate two full duplex T1 or two E1 communication links. Each data line can be channelized with a separate encryption context. The ESA provides IPSec Data Encryption Standard (DES) 56-bit and 3DES 168-bit encryption.
The remainder of this section includes the following topics:

To install the ESA, follow the procedures in the following sections:
•
Removing the Access Gateway Module
•
Installing the Encryption Service Adapter
•
Reinstalling the Access Gateway Module
Using Catalyst 4000 Slots
The Catalyst 4000 family switch reserves the top slot (slot 1) for a supervisor engine. You can use slots 2 or 3 (on the Catalyst 4003 switch, or slots 2 to 5 on the Catalyst 4006 switch) for other modules, such as the Access Gateway Module. Figure 3 shows the supervisor engine and switching module slots on the Catalyst 4003 switch.
Figure 3 Catalyst 4003 Switch Chassis
Warning
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Removing the Access Gateway Module
To remove a module from a Catalyst 4000 family switch, follow this procedure:
Warning
Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is OFF and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.
Warning
During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself.
CautionTo prevent ESD damage, handle modules by the carrier edges only.
To remove the Access Gateway Module from a Catalyst 4000 family switch, follow this procedure:
Step 1
Disconnect any network interface cables attached to the ports on the module.
Step 2
Loosen the captive installation screws (as shown in Figure 4) using the small flat-head or number 1 Phillips screwdriver.
Figure 4 Captive Installation Screws and Ejector Levers
Step 3
Grasp the left and right ejector levers and simultaneously pivot the levers outward to release the module from the backplane connector. Figure 4 shows a close-up of the right ejector lever.
Step 4
Grasp the module front panel with one hand and place your other hand under the module to support and guide it out of the slot, as shown in Figure 5. Do not touch the printed circuit boards or connector pins.
Figure 5 Removing the Access Gateway Module from the Catalyst 4000 Switch
Step 5
Carefully pull the Access Gateway Module straight out of the slot.
Step 6
Place the Access Gateway Module on an antistatic mat or antistatic foam, or immediately install it in another slot.
Step 7
If the slot will remain empty, install a module filler plate (part number 800-00292-01) to keep dust out of the chassis, to maintain proper airflow through the module compartment, and to prevent exposure to hazardous voltages and currents.
Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.
CautionBefore connecting system power or turning on the switch, ensure that the system is connected to a supplementary ground. For complete instructions on connecting the supplementary ground, refer to the Catalyst 4000 Family Installation Guide.
Warning
Before you install, operate, or service the system, read the Site Preparation and Safety Guide. This guide contains important safety information you should know before working with the system.
Installing the Encryption Service Adapter
To install the ESA, follow this procedure:
Step 1
Remove the Access Gateway Module as described in the previous section.
Step 2
Remove the three metal screws in the standoffs nearest the PCI connector with a small flat-head or number 2 Phillips screwdriver. Figure 6 shows the location of the screws.
Figure 6 Removing the Three Screws from the Standoffs
Note
In the illustration, we assume that you have already installed the Catalyst 4000 8-Port RJ21 FXS module. If not, refer to the Catalyst 4000 8-Port RJ21 FXS Module Installation and Configuration Note.
Step 3
Align the three holes on the ESA with the standoffs on the Access Gateway Module.
Step 4
Press down on the ESA until it is seated firmly in the PCI connector. Figure 7 shows how to align the adapter.
Figure 7 Aligning the Encryption Service Adapter and Reinstalling the
Six Screws into the Access Gateway Module.
Step 5
Reinsert the screws (removed from the Access Gateway Module) through the holes in the adapter. Hand tighten with the flat-head or Phillips screwdriver.
Step 6
After you have installed the ESA, the Access Gateway Module should look like Figure 8.
Figure 8 Installed Encryption Service Adapter
Reinstalling the Access Gateway Module
To reinstall the Access Gateway Module, follow this procedure:
Step 1
Connect an ASCII terminal or a PC running terminal emulation software to the console port on the supervisor engine.
Step 2
Choose a slot for the Access Gateway Module. Ensure that you have enough clearance to accommodate any interface equipment that you will connect directly to the Access Gateway Module ports. If possible, place modules between empty slots that contain only module filler plates.
Step 3
Align the sides of the Access Gateway Module with the guides in the slot (see Figure 9).
Figure 9 Reinstalling the Access Gateway Module in the Chassis
Step 4
Insert the Access Gateway Module into the slot until its front panel contacts the ejector levers. (See Figure 4 for an illustration of the ejector levers.) Avoid touching the components on the board.
Step 5
Using the thumb and forefinger of each hand, simultaneously push the left and right ejector levers in to seat the Access Gateway Module all the way into the backplane connector.
CautionAlways use the ejector levers when installing or removing modules. A module that is only partially seated in the backplane causes the system to halt.
Step 6
Use the flat-head or number 1 Phillips screwdriver to tighten the captive installation screws on the left and right sides of the Access Gateway Module. (See Figure 4.)
Step 7
Check the status of the Access Gateway Module as follows:
a.
After the module has booted and run diagnostics, ensure that its Status LED is green, indicating that the module is operational.
b.
Enter the show module command to verify that the system acknowledges the Access Gateway Module and reports its Status as ok in the screen display.
Configuring the Encryption Service Adapter
This section contains the following topics:
•
Configuring the T1 Channel Group
•
Configuring the Internet Key Exchange Security Protocol
•
Configuring IPSec Network Security
•
Configuring Encryption on the T1 Channel Group Serial Interface
Configuring the T1 Channel Group
Your first step toward configuring the ESA is to establish a T1 connection. This means defining the characteristics of a configuration group (such as speed and slot number).
To configure the T1 channel group, follow this procedure:
Configuring the Internet Key Exchange Security Protocol
Your second step is to establish a key exchange for encryption. This requires that you configure an exchange protocol.
To configure Internet Key Exchange (IKE) Security Protocol, follow this procedure:
Note
For information on how to create a private/public key and to download a certificate, refer to the following website: http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/secur_c/
scprt4/scdipsec.htm
Configuring IPSec Network Security
Your third step is to define how the T1 data will be handled.
To configure IPSec network security, follow this procedure:
Step Command PurposeStep 1
Gateway(config)# crypto ipsec security-association lifetime seconds seconds kilobytes kilobytesSpecify the lifetime of a security association. The default lifetimes are 3600 seconds (one hour) and 4608000 kilobytes (10 megabytes per second for one hour).
Step 2
Gateway(config)# crypto ipsec transform-set transform_set_name transform1 [transform2 [transform3]]Specify a transform set and enter transform-set configuration mode.
Note
A transform set represents a specific combination of security protocols and algorithms. During the IPSec security association negotiation, the peers search for a transform set that is the same on both peers. When such a transform set is found, it is selected applied to the protected traffic as part of both peers' IPSec security associations.
Step 3
Gateway(cfg-crypto-trans)# exit
Return to global configuration mode.
Step 4
Gateway(config)# crypto map map_name seq_num ipsec-isakmp [dynamic dynamic_map_name] [discover]
Create a crypto map. Enter crypto map configuration mode, unless you use the dynamic keyword.
Step 5
Gateway(config-crypto map)# set peer hostname|ip_address
Specify a remote IPSec peer.
Note
This is the same peer specified in Step 4 in the previous procedure, Configuring the Internet Key Exchange Security Protocol.
Step 6
Gateway(config-crypto map)# set transform-set transform_set_name
Specify the transform set allowed for this crypto map entry.
Note
This should be the same transform set specified in Step 2 of this procedure.
Step 7
Gateway(config-crypto map)# match address [access_list_id | name]
Specify an extended access list for a crypto map entry.
Step 8
Gateway(cfg-crypto-trans)# exitReturn to global configuration mode.
Step 9
Gateway(config)# access-list access_list_number {permit | deny} {type_code wild_mask | address mask}Create an access list.
Configuring Encryption on the T1 Channel Group Serial Interface
Your fourth step is to configure a T1 serial interface with an IP address and a crypto map.
To configure encryption on the T1 channel group, follow this procedure:
For complete information about configuration commands and about configuring LAN and WAN interfaces on your switch, refer to the Cisco IOS configuration guides and command references.
Verifying the Configuration
After configuring the new interface, use the following commands to verify that it is operating correctly:
•
show version—Display the router hardware configuration. Check that the list includes the new interface.
•
show controllers—Display all network modules and their interfaces.
•
show interfaces [type slot/port]—Display the details of a specified interface. Verify that the first line of the display shows the correct slot and port number and that the interface and line protocol are in the correct state (up or down).
•
show protocols—Display the protocols configured for the entire router and for individual interfaces. If necessary, add or remove protocol routing on the router or its interfaces.
•
show running-config—Display the running configuration.
•
show startup-config—Display the configuration stored in NVRAM.
•
ping—Send an echo request to a specified IP address.
Note
When you install the ESA hardware encryption is enabled by default . You can enable software encryption with the no crypto engine accel command. This command is useful for debugging problems with the ESA or for testing features available only with software encryption.
Note
If you have questions or need help, see Obtaining Technical Assistance.
Sample Configurations
The following topics are discussed:
•
Encrypting Traffic Between Two Networks
•
Exchanging Encrypted Data Through an IPSec Tunnel
Encrypting Traffic Between Two Networks
This sample configuration shows how to encrypt traffic between a private network (10.103.1.x) and a public network (98.98.98.x) using IPSec. The 98.98.98.x network knows the 10.103.1.x network by the private addresses. The 10.103.1.x network knows the 98.98.98.x network by the public addresses.
