Known Problems and Limitations

This section provides a list of known problems and limitations as known to HP at time of publication. If workarounds are available, they are included.

HP ProCurve Switches
When disabling Cisco's Fast Ether Channel protocol on the HP 9000 server, the HP ProCurve switches block that particular port from further use.
Corrective Action: In order to use the network physical port on the HP 9000 server, physically move the connection from the server to the switch to another non-Cisco Fast EtherChannel port on the switch.
Cisco Catalyst 5000 Switches
- Turning off Cisco's Fast Ether Channel protocol on one network physical port on the HP 9000 server might cause the entire link aggregate (the port it is associated with) to be deconfigured.
  Corrective Action: Reconfigure the switch; do not include the port in the link aggregate being configured. See the appropriate switch documentation for information on how to reconfigure link aggregates.
  The Catalyst 5000 switch only allows two- or four-port link aggregates. See the Cisco Catalyst 5000 Configuration Guide for information about these limitations.
- When interfacing a HSC 100Base-TX or PCI 4–port 100Base-TX to a Cisco Catalyst 5000 switch (with firmware version 4.5(4)) and ports in Desirable Mode connected to an HP server with ports running HP APA, the link aggregations might go up and down repeatedly.
  Corrective Action: Install patch PHNE_23465 or its superseding patch.
3Com SuperStack II Switches
To interoperate with the switch, disable the Trunk Control Message Protocol (TCMP) on all of the ports that are being used with HP Integrity servers.
