I have a Cisco 7301 VPN router with VAM2 module connected to a 50 Mbit Internet line.
This router connects the remote offices to the Headquater using GRE-in-IPSec VPN tunnels (currently
about 25 tunnels using Transport mode, AES encryption, COMP-LZS compression).
If there is a high traffic, I get a high amount of errors and drops in "sho crypto engine accelerator statistic 1":
ppq full errors : 123961
pkts dropped : 123961
What could be the problem?
Is this a performance problem of the VAM2?
Is there a way to tune/debug the VAM2?
