Global parameters
The root bridge sets the values for forward-time, hello-time, and max-age, and overwrites the values set on other bridges participating in
the RSTP group. Dell EMC recommends that only experienced network administrators change the RSTP group parameters. Poorly planned
modication of the RSTP parameters can negatively aect network performance.
Forward-time
15 seconds — Amount of time an interface waits in the Listening state and the Learning state before it transitions
to the Forwarding state.
Hello-time 2 seconds — Time interval in which the bridge sends RSTP BPDUs.
Max-age 20 seconds — Length of time the bridge maintains conguration information before it refreshes that information
by recomputing the RSTP topology.
Port cost Port cost values to set the path cost of the interface:
• 100-Mb/s Ethernet interfaces — 200000
• 1-Gigabit Ethernet interfaces — 20000
• 10-Gigabit Ethernet interfaces — 2000
• 40-Gigabit Ethernet interfaces — 500
• Port-channel with 100 Mb/s Ethernet interfaces — 200000
• Port-channel with 1-Gigabit Ethernet interfaces — 20000
• Port-channel with 10-Gigabit Ethernet interfaces — 2000
