Modifying Interface Stp Parameters - Dell S6100 Configuration Manual

PROTOCOL SPANNING TREE mode
hello-time seconds
NOTE: With large configurations (especially those with more ports) Dell Networking recommends increasing the hello-
time.
The range is from 1 to 10.
the default is 2 seconds.
• Change the max-age parameter (the refresh interval for configuration information that is generated by recomputing the spanning tree
topology).
PROTOCOL SPANNING TREE mode
max-age seconds
The range is from 6 to 40.
The default is 20 seconds.
To view the current values for global parameters, use the show spanning-tree 0 command from EXEC privilege mode. Refer to the

Modifying Interface STP Parameters

You can set the port cost and port priority values of interfaces in Layer 2 mode.
• Port cost — a value that is based on the interface type. The greater the port cost, the less likely the port is selected to be a forwarding
port.
• Port priority — influences the likelihood that a port is selected to be a forwarding port in case that several ports have the same port
cost.
The default values are listed in
To change the port cost or priority of an interface, use the following commands.
• Change the port cost of an interface.
