Hallo Thomas,

My first and quick guess is that you should enable client processing on the
channeled ports 27/28, the second switch now offers the SLB services and
should now the client ports.

cheers, Mike

Onderwerp: [load balancing] Filter redir and pip and LB HA

Hi all,

ich have a configuration problem with nortel 2424 Software Version 22.0.2

We have following network

 campus network
| |
| |
| |
| |

fw1 ----------fw2
| |
| vlan 410 |
| |
| |
port25 port25

lb1-----------lb2 trunk is port 27+28

port26 port26
| |
| vlan 430 |
| |
| |
| |
Switch1-------switch2
    | |
    server farm

If now port 26 on lb1 fail, the fw1 continue send the network traffic to
port 25 on lb1.
but the traffic never reach the real server over lb2.On lb2 now all services
active

Any idea?

a short extract from config file (we use filter and pip)
