set mrp timer

Use this command to set the value of Multiple Registration Protocol (MRP) timers on one or more ports.

Syntax

set mrp timer {[join timer-value] [leave timer-value] [leaveall timer-value] [periodic {enable | disable}]} port-string

Parameters

join timer-value Specifies the MRP Join timer value as defined in clause 10 of the 802.1Q standard. Valid values are 20 - 4294967295. The default value is 20 centiseconds (.2 seconds).
leave timer-value Specifies the MRP Leave timer value as defined in clause 10 of the 802.1Q standard. Valid values are 60 - 4294967295. The default value is 60 centiseconds (.6 seconds).
leaveall timer-value Specifies the LeaveAll timer value as defined in clause 10 of the 802.1Q standard. Valid values are 1000 - 4294967295. The default value is 1000 centiseconds (10 seconds).
periodic enable| disable Enables or disables the periodic events timer. The periodic timer has a fixed value of 1 second.
port-string Specifies one or a range of ports the MRP timer settings are applied to. For a detailed description of possible port-string values, refer to the S-, K-, and 7100 Series Configuration Guide.

Defaults

The MRP timers default to:

  • join – 20 centiseconds
  • leave – 60 centiseconds
  • leaveall – 1000 centiseconds
  • periodic – fixed at 1 second and disabled on all ports

Mode

All command modes.

Usage

You must enter at least one timer parameter for this command.

The setting of MRP timers is critical and should only be changed by personnel familiar with the 802.1Q standards documentation. If the default timer values are modified, the following relationships must be maintained:

  • The Leave timer should be at least twice the Join timer plus 30 centiseconds.
  • The LeaveAll timer should be large relative to the Leave timer.

Setting the LeaveAll timer to a value greater than the Leave timer helps to minimize the volume of rejoining traffic following a LeaveAll message.

MRP timers should be set to the same values on all linked devices.

Examples

This example shows how to set the MRP leave timer to 1 second on ports 1 through 24 for slot 1:

System(rw)->set mrp timer leave 100 ge.1.1-24

This example shows how to enable the MRP periodic timer on ports 1 through 24 for slot 1:

System(rw)->set mrp timer periodic enable ge.1.24
