Introduction

This document describes how to verify Internet Protocol Security (IPsec) feature on Catalyst 9300X switches.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

- IPsec

Components Used

The information in this document is based on these software and hardware versions:

- C9300X

- C9400X

- Cisco IOS® XE 17.6.4 and later

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Background Information

Starting in Cisco IOS® XE 17.5.1, Catalyst 9300-X series switches support IPsec. IPsec provides high levels of security through encryption and authentication, as well as protecting data from unauthorized access. The IPsec implementation on the C9300X provides secure tunnels between two peers using the sVTI (Static Virtual Tunnel Interface) configuration.

IPsec support on the Catalyst 9400X series switches was introduced in Cisco IOS® XE 17.10.1.

Terminology

IOSd

IOS daemon

This is the Cisco IOS daemon that runs on the Linux kernel. It is run as a software process within the kernel.IOSdprocesses CLI commands and protocols that build up state and configuration.

PD

Platform Dependent

Data and commands that are specific to the platform they are run on

IPsec

Internet Protocol Security

A secure network protocol suite  that authenticates  and encryptspackets  of data to provide secure encrypted communication between two computers over an Internet Protocol network.

SVTI

Static Virtual Tunnel Interface

A statically configured virtual interface to which you can apply security features

SA

Security Association

An SA is a relationship between two or more entities that describes how the entities use security services to communicate securely

FED

Forwarding Engine Driver

The switch component responsible for hardware programming of UADP ASIC

Configure

Network Diagram

For the purpose of this example, the Catalyst 9300X and ASR1001-X function as IPsec peers with IPsec Virtual Tunnel Interfaces.

Install HSEC license

Enable the IPsec feature on the Catalyst 9300X platform, two licenses are required: HSEC license (C9000-HSEC) and DNA-Advantage. This is different from other Cisco IOS XE based routing platforms that support IPsec, where an HSEC license is only needed to increase the allowed encryption throughtput. On the Catalyst 9300X platform, the tunnel mode and tunnel protection CLI is blocked if an HSEC license is not installed:

C9300X(config)#int tunnel1

C9300X(config-if)#tunnel mode ipsec ipv4

%'tunnel mode' change not allowed

*Sep 19 20:54:41.068: %PLATFORM_IPSEC_HSEC-3-INVALID_HSEC: HSEC license not present: IPSec mode configuration is rejected

Install the HSEC license when the switch is connected to CSSM or CSLU using Smart Licensing:

C9300X#license smart authorization request add hseck9 local

*Oct 12 20:01:36.680: %SMART_LIC-6-AUTHORIZATION_INSTALL_SUCCESS: A new licensing authorization code was successfully installed on PID:C9300X-24Y,SN:FOC2522L1W7

Verify HSEC license is correctly installed:

SVTI Tunnel Protection

IPsec configuration on the C9300X uses the standard Cisco IOS XE IPsec configuration. This is a simple SVTI configuration using IKEv2 Smart Defaults, where we are using the default IKEv2 policy, IKEv2 proposal, IPsec transform, and IPsec profile for IKEv2.

Verify

IPsec Tunnel

IPsec implementation on the C9300X platform is architecturally different that on the routing platforms (ASR1000, ISR4000, Catalyst 8200/8300, etc), where the IPsec feature processing is implemented in the QFP (Quantum Flow Processor) microcode.

The C9300X forwarding architecture is based on the UADP ASIC, so most of the QFP feature FIA implementation does not apply here.

Here are some of the key differences:

- show crypto ipsec sa peer x.x.x.x platform does not show the platform programming information from the FMAN down to the QFP.

- Packet-trace also does not work (more on this below).

- UADP ASIC does not support crypto traffic classification, so show crypto ruleset platform does not apply

IPsec control plane verification is exactly the same as that for the routing platforms, see . To display the IPsec SA installed in IOSd:

PD Control Plane

To verify the PD Control Plane operations, use the verification steps shown previously. To debug any issues related to the PD control plane, enable PD control plane debugs:

1. Increase the btrace logging level to verbose:

C9300X#set platform software trace forwarding-manager switch active f0 ipsec verbose

C9300X#show platform software trace level forwarding-manager switch active f0 | in ipsec

2. Enable PD controlplane conditional debugging:

C9300X#debug platform condition feature ipsec controlplane submode level verbose

C9300X#show platform conditions

Dataplane Packet-tracer

Packet-tracer on the UADP ASIC platform behaves very differently from that on the QFP based system. It can be enabled with either a manual trigger or a PCAP based trigger. Here is an example of using PCAP (EPC) based trigger.

1. Enable EPC and start capture:

C9300X#monitor capture test interface twentyFiveGigE 1/0/2 in match ipv4 10.1.1.2/32 any

C9300X#show monitor capture test
