mvrp timer

Sets the MVRP join, leave, and leave-all timer values on an Ethernet or port-channel interface.

Syntax

mvrp timer join cs leave cs leave-all cs
no mvrp timer join cs leave cs leave-all cs

Command Default

The join timer default value is 20 centiseconds (cs).

The leave timer default value is 100 cs.

The leave-all timer default value is 1000 cs.

Parameters

join cs
Specifies the join timer in centiseconds. Enter an integer from 20 to 10000000.
leave cs
Specifies the leave timer in centiseconds. Enter an integer from 100 to 10000000. The leave timer setting must be greater than or equal to twice the join timer setting plus 30 centiseconds.
leave-all cs
Specifies the leave-all timer in centiseconds. Enter an integer from 1000 to 10000000. The leave-all timer setting must be a minimum of three times the value of the leave timer setting.

Usage Guidelines

MVRP is supported on the Extreme 8820, SLX 9740, SLX 9640, and SLX 9540 devices only.

The no form of this command resets the timers to the global timer configuration. If the global timers have not been configured, the timers are reset to the default values.

Before configuring this command, you must configure the interface as switchport and globally enable MVRP on the device and on the interface to allow the MVRP-enabled interface to participate in the protocol.

This command requires that you configure the timer values in the specified order and you must configure all values.

When the network radius is large or the expected system load is higher normally, and since the default timer values are aggressive, Extreme recommends that you change the timer values to higher numbers to reduce the MVRP message exchanges and load on the system.

The configured timer settings on the individual MVRP-enabled interfaces override the global timer configuration.

The join timer is not run periodically but is triggered by the MVRP events and the device state changes. However, the leave-all timer is periodic required for garbage collection purposes.

Examples

The following example configures the MVRP timers on an Ethernet interface.

device# configure terminal
device(config)# protocol mvrp
device(config-mvrp)# exit
device(config)# interface ethernet 1/1
device(conf-if-eth-1/1)# switchport
device(conf-if-eth-1/1)# mvrp enable
device(conf-if-eth-1/1)# switchport mode trunk
device(conf-if-eth-1/1)# switchport trunk allowed vlan add 20-24
device(conf-if-eth-1/1)# mvrp timer join 40 leave 200 leave-all 2000
device(conf-if-eth-1/1)#
