There are two routes.

sending packet using route No. 1 ml ip address structure, starting:

ml flag (ml interface up or down) = 0x00000000 ml tick = 0

ml ip address = 0xc0a80203, 192.168.2.3

There are two preferred route pairs: from local if 0 to remote if 0 from local if 1 to remote if 1

There are two actual routes (two preferred).

---------------------------------------

from local if 0 to remote if 0 destination ip address structure:

if flag (up or down) = 0x000000c1 if tick = 0

ipaddr = 0xc0a80003, 192.168.0.3

---------------------------------------

from local if 1 to remote if 1 destination ip address structure:

if flag (up or down) = 0x000000c1 if tick = 0

ipaddr = 0xc0a80103, 192.168.1.3

5.12.3Packets dropped because of a hardware problem on an endpoint

To check for dropped packets at the HMC, check /var/adm/sni/sni_errpt_capture. Each hardware event has an entry. If you don't have the register mappings for error bits, check whether the errors are recoverable (non-MP-Fatal) or MP-Fatal. (MP-Fatal errors take longer to recover from and could be associated with more drops.)

The following is an example of Recoverable/Non Mp Fatal entry in /var/adm/sni/sni_errpt_capture:

Current time is:

Mon Oct 4 05:08:51 2004

Errpt Sequence num is: 3229

Errpt Timestamp is:

Mon Oct 4 05:08:51 2004

Event TOD is:

2004160209010410

Event TOD date:

Oct 04 09:02:16 2004
