transmit-interval (MACsec for MX Series)

 

Syntax

Hierarchy Level

Release Information

Statement introduced in Junos OS Release 15.1 for MX240, MX480, and MX960 routers.

Description

Specifies the transmit interval for MACsec Key Agreement (MKA) protocol data units (PDUs).

The MKA transmit interval setting sets the frequency for how often the MKA PDU is sent to the directly connected device to maintain MACsec on a point-to-point Ethernet link. A lower interval increases bandwidth overhead on the link; a higher interval optimizes the MKA protocol data unit exchange process.

The transmit interval settings must be identical on both ends of the link when MACsec using static connectivity association key (CAK) security mode is enabled.

We recommend increasing the interval to 6000 milliseconds in high-traffic and large scale configuration load environments.

Default

The default transmit interval is 2000 milliseconds.

Options

intervalSpecifies the transmit interval, in milliseconds.
