Crypto engine counters

Unanswered Question
Dec 21st, 2007

Hi,

i have 2801 cisco router with onboard crypto engine. I have misunderstand some counters in crypto engine statistics

Onboard crypto engine:

ds: 0x64AED5F8 idb:0x64AEC538

Statistics for Virtual Private Network (VPN) Module:

244045 packets in 244045 packets out

394 paks/sec in 394 paks/sec out

2487 Kbits/sec in 2560 Kbits/sec out

99098 packets decrypted 144947 packets encrypted

packet overruns: 0 output packets dropped: 0

tx_hi_drops: 0 fw_failure: 0

invalid_sa: 0 invalid_flow: 0

null_ip_error: 0 pad_size_error: 0 out_bound_dh_acc: 0

esp_auth_fail: 0 ah_auth_failure: 0 crypto_pad_error: 0

ah_prot_absent: 0 ah_seq_failure: 0 ah_spi_failure: 0

esp_prot_absent:0 esp_seq_fail: 0 esp_spi_failure: 0

obound_sa_acc: 0 invalid_sa: 0 out_bound_sa_flow: 0

invalid_dh: 0 bad_keygroup: 0 out_of_memory: 0

no_sh_secret: 0 no_skeys: 0 invalid_cmd: 0

pak_too_big: 0

tx_lo_queue_size_max 0 cmd_unimplemented: 0

flow_cfg_mismatch 0 flow_ip_add_mismatch: 0

unknown_protocol 0 bad_particle_align: 0

619 seconds since last clear of counters

Interrupts: Notify = 180299

What "Interrupts: Notify" mean? on another routers i have zero.

I have this problem too.

It just shows the router cpu sent interrupt to the crypto cpu to process some more crypto packets to be processed
