Validated SFPs for CSG700 Series Appliances

This article lists the small form-factor pluggable (SFP/SFP+) optics supported on the CSG700 series appliance fiber interfaces, and it describes the remote switches that have been tested with the SFPs.

Supported 1-Gigabit Ethernet SFP Tranceivers

The following table describes the 1-Gigabit Ethernet SFP transceiver modules supported on the CSG700 series appliances.

Type Manufacturer Part Number Transceiver Description
Short reach (SR) Finisar FTLF8519P3BNL 1000BASE-SX Ethernet SFP optical transceiver, 500-m extended temperature
Long reach (LR) Finisar FTLF1318P3BTL 1000BASE-LX Ethernet Gen 3 SFP optical transceiver, 10-km industrial operating temperature

Compatible Remote Switches

The following switches have been tested with a 1-Gigabit Ethernet link connection to CSG700 series appliances:

  • Cisco Nexus 3048T
  • Dell S3048 and S4128F
  • Juniper EX2200

Connection Recommendations

The following are recommendations for connecting at 1-Gigabit Ethernet speeds:

  • After you dynamically insert an SFP or change the SFP speed, you must disable and then reenable the VNI interface on the CSG700 appliance.
  • If the configuration on the remote device changes, you must disable and then re-enable the VNI interface on the CSG700 appliance.
  • Ensure that you have enabled the 1-Gigabit Ethernet interface in the Versa Operating SystemTM (VOSTM) software.
  • For 1-Gigabit Ethernet SFPs, you must turn off autonegotiation on the remote device, and you must set the connection speed 1-GE. For example, for Cisco switches, in the interface configuration, configure the speed to 1000:
interface Ethernet 1/25
speed 1000

For Juniper switches, configure no-auto-negotiation on the interface:

enable;
ether-options {
    no-auto-negotiation;
    link-mode full-duplex;
    speed {
        1g;
    }
}

Note: Before you order units in bulk, validate connections with the target remote device in a lab or testing environment to ensure that there are no compatibility or link issues.

Compatibility Issues

  • Link flap issues may occur if the remote device is an older Cisco Nexus 3064 switch (2012).
  • After you reboot CSG700 appliances, the link error "DCX-NO Ack in 100 PDUs" may occur on Cisco Nexus switches. As a workaround, issue the shutdown command followed by a no shutdown on the Cisco switch interface that is used for link detection.
  • BASE-T SFP modules for Denverton-based boards are not supported.
