Network Elements

Starting 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 and SNMP v2 and v3

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.
Table 1. Interface attributes supporting DRC and idempotency
Field Identify Drift Reconcile configuration Idempotency
Admin-state Yes Yes Yes
Breakout mode Yes Yes No
Speed Yes Yes Yes
Layer-2 MTU Yes Yes Yes
IPv4 MTU Yes Yes Yes
IPv6 MTU Yes Yes Yes
FEC mode Yes Yes Yes
Link error disable Yes Yes Yes
Toggle-threshold Yes Yes Yes

RME enable Yes Yes Yes
The following CLI commands are available:
  • efa inventory device interface redundant-management
  • efa inventory device interface set-fec
  • efa inventory device interface set-link-error-disable
  • efa inventory device interface unset-fec
  • efa inventory device interface unset-link-error-disable

Global or System-level Configuration

The following tables capture the various attributes of SNMP and NTP for which DRC and idempotency is supported.

  • A drift is identified if any of the fields below is modified through the SLX, CLI command, or other management tools.
  • A reconcile operation pushes the intended configuration to SLX, so bringing the SLX configuration in sync with EFA.

SNMP Configuration

Note

Note

Regarding idempotency for creating an entry which already exists in EFA, an error message is returned stating that the user already exists.
Table 2. SNMP attributes supporting DRC and idempotency

Modify read review or write view or notify view associated with group Yes Yes Not Applicable
Modify group name associated with SNMP user Yes Yes Not Applicable
Modify authentication protocol associated with SNMP user Yes Yes Not Applicable
Modify authentication password associated with SNMP user Yes Yes Not Applicable
Modify privacy protocol associated with SNMP user Yes Yes Not Applicable
Modify privacy password associated with SNMP user Yes Yes Not Applicable

Modify encrypted keyword associated with SNMP user Yes Yes Not Applicable
Modify authentication type associated with group, that is, auth, noauth, notify Yes Yes Not Applicable
Delete SNMP host entry Yes Yes No A valid error message is shown when a non-existent host is deleted
Update SNMP host severity level Yes Yes Not Applicable Any drift observed from EFA configured default severity level is reconciled
Update SNMP host source interface Yes Yes Not Applicable Any drift observed from EFA configured default source interface is reconciled
Update SNMP host UDP port Yes Yes Not Applicable Any drift observed from EFA configured default UDP port is reconciled
Update SNMP host VRF Yes Yes Not Applicable Any drift observed from EFA configured default VRF is reconciled
Update SNMP host engine id Yes Yes Not Applicable
Update of SNMP host notification type (traps, informs) Yes Yes Not Applicable
Update of SNMP view MIB OID access (included, excluded) Yes Yes Not Applicable
The following CLI commands are available for operations on SNMP interfaces:
  • efa inventory device snmp community create
  • efa inventory device snmp community delete
  • efa inventory device snmp community list
  • efa inventory device snmp user create
  • efa inventory device snmp user delete
  • efa inventory device snmp user list
  • efa inventory device snmp host create
  • efa inventory device snmp host delete
  • efa inventory device snmp host list

For more information, see the Extreme Fabric Automation Command Reference, 2.5.0 .

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.

Table 3. NTP attributes supporting DRC and idempotency
Field Identify Drift Reconcile configuration Idempotency Comments
NTP auth key ID associated with NTP serer is modified Yes Yes Not Applicable
NTP auth key name associated with NTP serer is modified Yes Yes Not Applicable
NTP server deleted Yes Yes No A valid error message is shown when a non existent NTP server is deleted.
Encryption type is modified Yes Yes Not Applicable
Trusted key is modified Yes Yes Not Applicable
Encryption level is modified Yes Yes Not Applicable
NTP server disable modified Yes Yes Not Applicable
The following CLI commands are available for operations on NTP interfaces:
  • efa inventory device ntp server create
  • efa inventory device ntp server delete
  • efa inventory device ntp server list
  • efa inventory device ntp disable-server

For more information, see the Extreme Fabric Automation Command Reference, 2.5.0 .

Time Zone Configuration

By default, SLX devices come up with the GMT timezone. Using the efa inventory device timezone command, you can set the timezone per device.
