Questions & Answers
What is the Cisco 2921-HSEC+/K9 VPN ISM module?
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.
Which Cisco Integrated Services Routers support the HSEC+ module?
The HSEC+ ISM is fully compatible with Cisco 2900 Series ISR platforms, including the ISR 2911, 2921, 2951 models running appropriate IOS images.
What maximum VPN throughput does the 2921-HSEC+ module provide?
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.
How many concurrent VPN tunnels can the HSEC+ ISM support?
The module supports up to 2500 active IPsec VPN tunnels concurrently, ensuring scalable secure connectivity for branch and remote users.
Does the HSEC+ module require additional licensing?
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.
How do I install the Cisco 2921-HSEC+ ISM on my router?
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.
Is the HSEC+ module hot-swappable?
No, the HSEC+ ISM is not hot-swappable. You must power off the ISR before inserting or removing the module to avoid hardware damage.
Which cryptographic algorithms does the HSEC+ support?
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.
Can the HSEC+ handle both firewall and VPN services simultaneously?
Yes. The HSEC+ ISM offloads both IPsec encryption/decryption and Cisco ISR firewall (CBAC) operations in hardware, preserving router CPU for other tasks.
What is the difference between HSEC and HSEC+ modules?
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.
Does the HSEC+ module support FIPS 140-2 compliance?
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.
What Cisco IOS software is required for HSEC+ operation?
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.
How do I verify HSEC+ performance and status?
Use IOS commands like “show crypto engine connections active” and “show platform hardware throughput ism” to monitor encryption sessions and module utilization.
Is firmware upgrade required for the HSEC+ ISM?
The HSEC+ ISM firmware is updated automatically with compatible Cisco IOS releases. No separate firmware file is needed; just upgrade your router image.
What warranty and support does Cisco offer for the HSEC+ module?
Cisco provides a 90-day limited hardware warranty. Optional Cisco SMARTnet contracts extend coverage with 24/7 technical support, hardware replacement, and OS updates.
How do I troubleshoot HSEC+ installation issues?
Check slot seating, power cycle the router, verify IOS compatibility, and review “show logging” for ISM errors. Contact Cisco TAC if unresolved.
Where can I purchase genuine Cisco 2921-HSEC+ ISM modules?
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.
