Question 1

What is the Cisco 2921-HSEC+/K9 VPN ISM module?

Accepted Answer

The Cisco 2921-HSEC+/K9 is a High-Speed Encryption (HSEC+) ISM that delivers hardware-accelerated IPsec VPN and stateful firewall services on the ISR 2921 platform.

Question 2

Which Cisco Integrated Services Routers support the HSEC+ module?

Accepted Answer

The HSEC+ ISM is fully compatible with Cisco 2900 Series ISR platforms, including the ISR 2911, 2921, 2951 models running appropriate IOS images.

Question 3

What maximum VPN throughput does the 2921-HSEC+ module provide?

Accepted Answer

Under optimal conditions, the HSEC+ module delivers up to 225 Mbps of aggregate IPsec VPN throughput for secure site-to-site and remote access tunnels.

Question 4

How many concurrent VPN tunnels can the HSEC+ ISM support?

Accepted Answer

The module supports up to 2500 active IPsec VPN tunnels concurrently, ensuring scalable secure connectivity for branch and remote users.

Question 5

Does the HSEC+ module require additional licensing?

Accepted Answer

No extra license is required; the HSEC+ ISM includes built-in hardware encryption capabilities. You only need a valid Cisco IOS Security feature set on your ISR.

Question 6

How do I install the Cisco 2921-HSEC+ ISM on my router?

Accepted Answer

Power down the ISR, slide the HSEC+ ISM into the dedicated ISM slot until it clicks, then reboot. Finally, verify installation with the IOS “show ism” command.

Question 7

Is the HSEC+ module hot-swappable?

Accepted Answer

No, the HSEC+ ISM is not hot-swappable. You must power off the ISR before inserting or removing the module to avoid hardware damage.

Question 8

Which cryptographic algorithms does the HSEC+ support?

Accepted Answer

The module supports AES-256, AES-128, 3DES, SHA-1, SHA-256, MD5, and Diffie-Hellman Group 2, 5, 14, 19, and 20 for strong IPsec tunnels.

Question 9

Can the HSEC+ handle both firewall and VPN services simultaneously?

Accepted Answer

Yes. The HSEC+ ISM offloads both IPsec encryption/decryption and Cisco ISR firewall (CBAC) operations in hardware, preserving router CPU for other tasks.

Question 10

What is the difference between HSEC and HSEC+ modules?

Accepted Answer

HSEC+ offers higher throughput (up to 225 Mbps), more VPN tunnels, and enhanced algorithm support compared to the legacy HSEC ISM, which tops at 85 Mbps.

Question 11

Does the HSEC+ module support FIPS 140-2 compliance?

Accepted Answer

Yes, with the appropriate FIPS-compliant IOS image and secure boot configuration, the HSEC+ ISM meets FIPS 140-2 Level 2 requirements for cryptographic modules.

Question 12

What Cisco IOS software is required for HSEC+ operation?

Accepted Answer

You need Cisco IOS Software Release 15.1(3)M or later with the Security feature license (SEC), optimized for hardware encryption and firewall services.

Question 13

How do I verify HSEC+ performance and status?

Accepted Answer

Use IOS commands like “show crypto engine connections active” and “show platform hardware throughput ism” to monitor encryption sessions and module utilization.

Question 14

Is firmware upgrade required for the HSEC+ ISM?

Accepted Answer

The HSEC+ ISM firmware is updated automatically with compatible Cisco IOS releases. No separate firmware file is needed; just upgrade your router image.

Question 15

What warranty and support does Cisco offer for the HSEC+ module?

Accepted Answer

Cisco provides a 90-day limited hardware warranty. Optional Cisco SMARTnet contracts extend coverage with 24/7 technical support, hardware replacement, and OS updates.

Question 16

How do I troubleshoot HSEC+ installation issues?

Accepted Answer

Check slot seating, power cycle the router, verify IOS compatibility, and review “show logging” for ISM errors. Contact Cisco TAC if unresolved.

Question 17

Where can I purchase genuine Cisco 2921-HSEC+ ISM modules?

Accepted Answer

Authorized Cisco partners and resellers list the HSEC+ ISM under SKU CISCO2921-HSEC+/K9. Always verify with Cisco’s official price list or partner portal.
