Jermaine-

This typically indicates sessions that have been created, but have not
been assigned to a real server, yet. This can occur if you are using
delayed binding, where the handshake hasn't occurred yet, for example.

Subject: [load balancing] Strange Session Table Entries on Alteon 10.0

I'm running 10.0.26 on an AD3 with VMA enabled. I'm seeing strange
session table entries with bogus IP addresses on all VMA ports. Here
are some samples:

  2,14130: 83.2.177.75 0->18226, 0.0.0.0 1 ALLOW age 4 E
  2,14135: 45.103.172.139 0->18231, 0.0.0.0 ALLOW age 4 E
  3,16094: 72.230.11.160 11, 0.0.0.0 3 ALLOW age 4 EPS
  4,4212: 25.123.140.167 0->8308, 0.0.0.0 ALLOW age 2 E
  7,13662: 237.26.233.41 3, 0.0.0.0 3 ALLOW age 4 EPS
  9,17565: 100.227.109.66 0->21661, 0.0.0.0 ALLOW age 2 E
  9,17569: 192.83.110.188 0->21665, 0.0.0.0 ALLOW age 2 E
  9,17576: 81.243.133.99 26, 0.0.0.0 5 ALLOW age 0 PS
  9,17581: 192.231.234.28 0->21677, 0.0.0.0 ALLOW age 2 E
  9,17582: 8.152.39.115 0->21678, 0.0.0.0 ALLOW age 4 E

I cleared the session table and ran packet traces on all switch ports in
the server farm. But I never saw those IP addresses in the packet trace
and I can see the entries slowly trickle into the session table. I
thought it might have been bad switch ports, but I've seen this behavior
in two other installations. Has anyone seen this?

Thanks,
Jermaine
