Table 66: RSTP Configuration Fields (continued)
Field
Max Age
Hello time
Forward Delay
Bpdu Block on Edge
Interface
Configuring STP (NSM Procedure)
108
Function
Specifies the maximum-aging time for
all MST instances. The maximum aging
time is the number of seconds a switch
waits without receiving spanning-tree
configuration messages before
attempting a reconfiguration.
Specifies the hello time for all MST
instances.
Specifies the number of seconds a port
waits before changing from its
spanning-tree learning and listening
states to the forwarding state.
Specifies whether Bpdu blocks must be
processed.
Specifies MSTP settings for the interface
and Bpdu timeout action.
Devices such as EX-series switches provide Layer 2 loop prevention through Spanning
Tree Protocol (STP), Rapid Spanning Tree protocol (RSTP), and Multiple Spanning Tree
Protocol (MSTP). Configure BPDU protection on interfaces to prevent them from receiving
BPDUs that could result in STP misconfigurations, which could lead to network outages.
To configure STP:

1.
Click the expand icon.
2. Specify the interface name.
3. Specify the port priority.
4. Specify the path cost. MSTP uses the
path cost when selecting an interface
to place into the forwarding state. A
lower path cost represents
higher-speed transmission.
5. Specify the mode. The link type can
be shared or point-to-point.
