Seeing Ierrors and in_checksum errors on most interfaces on a IP390, 2 node cluster running IPSO 4.2B051-HFA02, NGX65HFA_02, IPSO clustering,
unicast, static.
The primary,2nd and fw1 sync i/f's are all on their own network.
The other data carrying cluster i/f's all show the above errors except one i/f which connects to a managed cisco 3750 switch for both modules.
The other data carrying i/f's connect too unmanaged D-Link, switchs, all 100FDX.
The 3 sync i/f's connect to Linksys unmanaged switchs, all 100FDX.
All i/f's in voyager configured for 100FDX, auto-avertise off.
All cabling has been replaced with cat 5e with no effect (original was 5e also)

Below are outputs for netstat -ni on both modules.

Note: Cluster A, s1p1, eth3 no errors, Cluster B s1p1, eth2, eth3 no errors

Issuing command ipsctl -a |grep errors results in only the follwing displaying errors on all i/f's with Ierrs above.
errors:in
errors:rx_relc
errors:in_checksum

I suspect it has somthing to do with the umanaged D-Link and Linksys switchs.
Any assistace would be appreated as i suspect this is the cause of slow performance all round...Read my other post "R65, IPSO Cluster, slow web browsing " for topology details...
