Configuring the SA-VAM2+
To see if the SA-VAM2+ is currently processing crypto packets, enter the show pas vam interface
command. The following is sample output:
Router# show pas vam interface
VPN Acceleration Module Version II+ in slot : 3
Errors:
Unwrappable object
When the SA-VAM2+ processes packets, the "packets in" and "packets out" counter changes. Counter
"packets out" represents the number of packets directed to the SA-VAM2+. Counter "packets in"
represents the number of packets received from the SA-VAM2+.
The show pas vam interface command output includes 'compression ratio' (or the efficiency of the
Note
tunnel bandwidth) which represents the ratio of the original packet to the compressed packet plus the
ipsec headers. It does not represent the ratio of the ipsec payload before compression to the ipsec payload
after compression.
This ratio may fall below 1 when small packets are not compressible, resulting in the ratio representing
unencrypted packet to the encrypted packet plus the ipsec header.
