Network Elements

Starting in EFA v2.5.0, in addition to fabric and tenant service configurations, the following asset service configurations are persisted and included in Drift and Reconcile (DRC).

The support is on two levels:
  • Interface level configuration: Breakout mode, MTU, admin state, speed, FEC configuration, port dampening (link-error disable), and RME
  • Global or system level configuration: NTP, SNMP v2 and v3, prefix list, and route map

Interface-level Configuration

The following table captures the various attributes of interface for which DRC and idempotency is supported.

Note

Note

Clean up explicitly any conflicting configuration which could cause reconciliation of device to fail. For example, if EFA configures a port as breakout and if that configuration is drifted by adding Layer 3 configuration to a parent interface, the reconciliation fails. It is recommended to explicitly remove the conflicting configuration from the device through the SLX CLI and retry the DRC process.

The clear IP route command allows the user to clear a device's IPv4 and IPv6 routes. Users have the option to either clear an IPv4 or an IPv6 route.

The following CLI command is available for clearing IP route:
  • efa inventory device clear route-all
Note

Note

Drift and reconcile and idempotency configuration support is not applicable for clear IP route attribute.

NTP Configuration

The NTP commands let you configure NTP server configuration on the SLX device. The configuration you set is persisted in the EFA database. DRC is also supported.

The following table captures the various attributes of the NTP configuration interface for which DRC and idempotency is supported. A drift is identified if any of the following fields are modified by you through SLX CLI or other management tools. Reconcile operation pushes the intended configuration to SLX which makes the SLX configuration synchronize with EFA.

On idempotency for creating an entry which already exists in EFA, an error message is returned stating that user already exists.
