NOTE: In a VLAN setup that contains IOM fabrics running more than 100 VLANs, enable RSTP before deploying the
template from MSM.
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.
NOTE:
Dell EMC recommends that only experienced network administrators change the RSTP group parameters. Poorly
planned modification of the RSTP parameters can negatively affect network performance.
Forward-time 15 seconds — Amount of time an interface waits in 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 configuration information before it refreshes that
information by recomputing the RSTP topology.
Port cost Port cost values to set the path cost of the interface:

● 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 1x40Gigabit Ethernet interface — 500
● Port-channel with 2x40Gigabit Ethernet interfaces — 250
● Change the forward-time in CONFIGURATION mode, from 4 to 30, default 15.

● Change the hello-time in CONFIGURATION mode, from 1 to 10, default 2. With large configurations, especially those
configurations with more ports, Dell EMC recommends increasing the hello-time.
