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

5.12.3 Packets 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

Not MP Fatal

DSS Log count = 07

1st Attn type = Recoverable
