RE: [load balancing] struggling alteon 180e dsr config

Glad you got it working

Flags;
P - permanent
4 - Layer 4 entry i.e. VIP

The VIP sits in all VLANS so there is no VLAN/port reference

Referenced ports are ports which are using the entry for forwarding.
For permanent 4 entries this should be all ports 1-9

Client processing is required on a port where the client is to be able
to ping the VIP (as you have found out).

yes, that's exactly what i mean! sorry if i wasn't clear. indeed,
without responding to arps, nothing will work.

i was looking at /i/arp/dump and i see:

    IP address Flags MAC address VLAN Port Referenced ports
  --------------- ----- ----------------- ---- ---- ----------------
  192.168.1.1 00:0e:0c:05:04:51 1 1 empty
  192.168.1.5 00:02:b3:a3:0e:00 1 1 empty
  192.168.1.6 00:02:b3:a3:0e:21 1 1 empty
  192.168.1.150 P 00:60:cf:49:46:30 1 1-9
  192.168.1.160 P 4 00:60:cf:49:46:3e 1-9

i have no idea what the '4' is. i also don't know why the vip isn't on
any port. it should be on port 1, shouldn't it? and why isn't it in
any vlan (even default 1) when everything else is.

right. sorry if i wasn't clear. the problem is that it's not
responding to requests about 1.160 in this case.

thanks,
