The Redundant Management Interface feature provides fault tolerance for the management path.
Note
Redundant Management is supported on the SLX 9250 and the SLX 9740.eth0 is a logical virtual bridge interface serving both SLX-Linux and TPVM. It has a secondary interface bond0, which is a Linux LAG inActive-Standby mode, providing fault-tolerance on the Management Path. bond0 has a preconfigured Primary-Active member, eth3. Primary implies this member is used and active whenever available. The eth3 interface represents the physical management interface RJ45 port available on the front panel. For fault tolerance, you can select a standby member from any of the front panel ports, with any native speed.
When selecting a standby port, use a port that supports 1Gbe speed and a Mellanox Adaptor with 1Gbe Cu SFP. The standby member is used only if the active member becomes disconnected.
To configure Redundant Management, define eth3 as the Active-Primary management port, and configure a physical port on the device (for example, eth0/15) as a standby management port. This port is configured to in-band mode, making it available as part of the mgmt-vrf. Both the configured port (eth0/15) and eth3 are physically connected to different Layer two management switches with the same default gateway.
