Moxa EDR-810-VPN-2GSFP [49/74] Spanning tree hello time

CLI Command Set User's Manual Layer 2 Functions

spanning-tree hello-time

Use the spanning-tree hello-time redundancy configuration command on the switch to set the interval

between hello bridge protocol data units (BPDUs) sent by root switch configuration messages. Use the no form

of this command to return to the default setting.

Commands

Redundancy configuration

2*( hello-time + 1.0 sec) <= max-age <= 2*( forward-delay - 1.0 sec)

<UINT:seconds> - Range from 1 to 2 seconds

BPDU hello time must be in the range from 1 to 2 secs

spanning-tree max-age

Use the spanning-tree max-age redundancy configuration command on the switch to set the interval

between messages that the spanning tree receives from the root switch. If a switch does not receive a bridge

protocol data unit (BPDU) message from the root switch within this interval, it recomputes the spanning-tree

topology. Use the no form of this command to return to the default setting.

Commands

spanning-tree max-age seconds

no spanning-tree max-age

2*( hello-time + 1.0 sec) <= max-age <= 2*( forward-delay - 1.0 sec)

<UINT:seconds> - Range from 6 to 40 seconds

The BPDU forward delay time must be in the range from 4 to 30 secs

The formula must be obeyed:

2 x (Hello Time + 1 sec) <= Max age <= 2 x (Forward Delay - 1 sec)
