Scalability Support

The following table contains the details of scalability tested in this release:

100GE Flex Supported Transceivers

Operational Considerations

This section documents the operational considerations
related to Skylight Flex 100.

Access Control List Considerations

The order of operation/matching of ACL rules is based on the order of the ACL configuration; a separate field/configuration to specify priority of the ACL is not supported.

ACLs associated with the port, when requiring modification, will have to be deleted and reconfigured with updated field value.

Compatibility

Presently, Skylight Flex 100 has compatibility issues with the Vitex QSFP28, 100GBASE-ER4 transceiver; using this transceiver is not recommended.

RoadRunner Considerations

RoadRunner runs in a Docker container and is the software agent that monitors, polls, and transfers raw data files from Skylight Flex 100 to Skylight analytics.

In relation to PM telemetry, under some scenarios Skylight analytics does not present SLM or DMM data when two or more MEPs are configured. The latest version of Skylight analytics is required.

L2CP Tunneling Limitations

Under certain circumstances (port-based scenarios), MMRP and GMRP are not operational.

NETCONF Limitations

NETCONF management can only be made via the default credentials in the OS which are currently restricted to the admin username.

Addressed Issues

This section lists issues corrected in Skylight Flex 100 release 22.01.2.

Bandwidth regulator mechanism (Meter) exceeds CIR values

This issue has been fixed.

Unable to pass SOAM (CCM) forwarding when using port Customer Edge port configuration

This issue has been fixed.

Unable to pass tagged and untagged traffic on the same port if VLANs are not known

This issue has been fixed.

Test set traffic stops passing when destination IP is 0.0.0.0.

This issue has been fixed.

Device must be reloaded for the SFP to appear and the port to go up
When connecting a new SFP in any port, the Skylight Flex 100 must be reloaded in order for the SFP to appear and the port to go up.

This issue has been fixed.

Attempting SSH connections using SSH-1 (RSA) Keys will force Skylight Flex 100 to reboot

This issue has been fixed.

SSH connectivity failure due to a memory leak in the system

This issue has been fixed.

OAM IEEE 802.1ag / ITU-T Y.1731 DMM interval configuration is not supported

This issue has been fixed.

Output is showing all FD/FDV values as 0.000ms
When running the command show eth cfm proactive frame delaybuffer domain MD-L2 mpid 2 switch default, output is showing all FD/FDV values as 0.000ms.

This issue has been fixed.

The SLM Sent column is empty by design
The “Suspect” flag and associated column in the CSV file is introduced and used to determine whether the computed results (i.e. “Near end packet loss ratio (%)” and “Far end packet loss ratio (%)” columns) are valid (Suspect == False) or invalid (Suspect == True).

This issue has been fixed.

Telemetry reporter does not send the records if NTP is not properly set
The SSL certificate validation will fail; this is a normal behavior.

This issue has been fixed.

Users are prevented from using values higher than 2 for max-port
Despite this, configuring max-port to more than 2 is possible.

This issue has been fixed.

ESAT frames are not reflected if reflector Skylight Flex 100 is configured in Provider Edge Bridge mode
Without VLAN configurations, ESAT frames are not reflected if reflector Skylight Flex 100 is configured in Provider Edge Bridge mode (which is the default and recommended mode for Flex 100 units). When in Provider Edge Bridge mode, VLAN must be configured in order to reflect.

When the Skylight Flex 100 unit is configured in Customer Bridge Mode, no VLAN configuration is required on reflector Flex 100 Unit.

This issue has been fixed.

Unexpected value in the SNMP Traps generated for 802.1ag MEP defects

This issue has been fixed.

Inconsistency in displaying priority 7 in show running-config printouts
There is inconsistency in displaying priority 7 in show running-config printouts when configured in ethernet cfm proactive commands. There is no such issue when the priority is between 0 and 6.

This issue has been fixed.

LAG configuration is not allowed on CustomerEdgePort interface

This issue has been fixed.

“Loss of continuity" alarm is raised when the UNI port is down
When the UNI port is down, the “loss of continuity" alarm is raised despite there still being continuity between the two Skylight Flex 100 units.

This issue has been fixed. However, spanning-Tree (STP) must be disabled for correct ETH-CSF behavior to occur.

ETH-CSF over LAG (UNI interface) is not supported

This issue has been fixed.
