hello-time

no hello-time
Context config>service>vpls>stp
config>template>vpls-template>stp
Description This command configures the Spanning Tree Protocol (STP) hello time for the Virtual Private LAN
Service (VPLS) STP instance.
The hello time parameter defines the default timer value that controls the sending interval between
BPDU configuration messages by this bridge, on ports where this bridge assumes the designated role.
The active hello time for the spanning tree is determined by the root bridge (except when the STP is
running in RSTP mode, then the hello time is always taken from the locally configured parameter).
The configured hello-time can also be used to calculate the forward delay. See auto-edge on page 398.
The no form of this command returns the hello time to the default value.
Default 2 seconds
Parameters hello-time — The hello time for the STP instance in seconds.
Values 1 — 10
