since we have replaced our Catalyst 2924XL switches with Catalyst 2950 we get more and more problems with Apple Macintosh OS X 10.4 Systems with G5 processors. The systems get their static IP addresses from two SuSE Linux DHCP-Servers. In our campus-LAN 76 VLANs are configured.
Normally everything works well, but sometimes some Mac OS X 10.4 systems lose suddenly their server mounts. Sometimes other Mac OS X 10.4 systems don´t get an IP address while booting. After a reboot it works regularly. Deactivating the port-security doesn´t help. "Spanningtree portfast" and "switchport nonegotiate" is configured on the switchport.
Has anyone a hint on this problem? Thanks in advance! Kai Matthies
