Spanning-Tree Protocol (Stp) And Fast-Uplink Problems - HP ProCurve 6400cl Series Management And Configuration Manual

Ensure that the radius-server timeout period is long enough for network
■
conditions.
■ Verify that the switch is using the same UDP port number as the server.
RADIUS server fails to respond to a request for service, even though
the server's IP address is correctly configured in the switch. Use
show radius to verify that the encryption key the switch is using is correct for
the server being contacted. If the switch has only a global key configured, then
it either must match the server key or you must configure a server-specific
key. If the switch already has a server-specific key assigned to the server's IP
address, then it overrides the global key and must match the server key.

Spanning-Tree Protocol (STP) and Fast-Uplink
Problems
If you enable STP, it is recommended that you leave the remainder of the STP
parameter settings at their default values until you have had an opportunity
to evaluate STP performance in your network. Because incorrect STP settings
can adversely affect network performance, you should avoid making changes
without having a strong understanding of how STP operates. To learn the
details of STP operation, refer to the IEEE 802.1D standard.
