We have DLSW trough a tunnel between two C3640 and a VPN accelerator card.
We have received the following message and he tunnel went down:
Aug 31 13:37:52: %HW_VPN-1-HPRXERR: Hardware VPN3/8: Packet Encryption/Decryption error, status=4615
Aug 31 13:50:11: %DUAL-5-NBRCHANGE: IP-EIGRP 10: Neighbor 10.37.0.18 (Tunnel0) is down: holding time expired
Any idea of what could happen ?
Thanks,
Algis
