HP-UX IPSec Version A.03.02.02 Administrator's Guide HP-UX 11i version 2 and HP-UX 11i version 3 (762800-001, April 2014)

you restart HP-UX IPSec, the Cisco device may attempt to use its existing IKE SA to negotiate
IPsec SAs with HP-UX IPSec. This causes a negotiation failure. As a workaround, login to the
Cisco device and manually delete any IKE SAs to an HP-UX system that remain after you stop
HP-UX IPSec.
HP Printers
HP-UX IPSec will interoperate with any HP printer with an HP Jetdirect 635n installed. The features
tested with HP-UX IPSec A.02.01 HP printers include the following:
• IKE with preshared key authentication.
• IKE with Main Mode and Aggressive Mode.
• Transport IPsec transforms.
• Tunnel IPsec transforms.
• IPv4 addresses.
• IPv6 addresses.
The implementation of IPsec on HP printers supports a superset of the encryption algorithms supported
by HP-UX IPSec.
