434BConfiguring the maximum port rate
The maximum rate of a port refers to the maximum number of BPDUs the port can send within each hello
time. The maximum rate of a port is related to the physical status of the port and the network structure.
The higher the maximum port rate is, the more BPDUs will be sent within each hello time, and the more
system resources will be used. By setting an appropriate maximum port rate, you can limit the rate at
which the port sends BPDUs and prevent spanning tree protocols from using excessive network resources
when the network becomes unstable. HP recommends you to use the default setting.

435BConfiguring edge ports
If a port directly connects to a user terminal rather than another device or a shared LAN segment, this
port is regarded as an edge port. When network topology changes occur, an edge port will not cause
a temporary loop. Because a device does not determine whether a port is directly connected to a
terminal, you must manually configure the port as an edge port. After that, the port can transition rapidly
from the blocked state to the forwarding state.
1141BConfiguration restrictions and guidelines
• If BPDU guard is disabled, a port set as an edge port will become a non-edge port again if it
receives a BPDU from another port. To restore the edge port, re-enable it.
• If a port directly connects to a user terminal, configure it as an edge port and enable BPDU guard
for it. This enables the port to transition to the forwarding state quickly while ensuring network
security.
• You cannot configure edge port settings and loop guard on a port at the same time.
