Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

    Introduction

    This document describes the usage and limitations of the CVR-QSFP-SFP10G adaptor on the C9600-LC-24C line card on the Catalyst 9600 platform.

    Usage

    C9600-LC-24C line card on the C9600 platform has 24 QSFP ports that support 40G & 100G optics. You cannot directly insert an SFP-based 10Gbps or 1Gbps optics on these ports.

    CVR-QSFP-SFP10G adaptor gives the flexibility to use SFP based 10Gbps or 1Gbps optics on QSFP based ports of C9600-LC-24C line card on the C9600 platform.

    These CLI's can be used to check the port mapping. Their operational speed mode and physical to virtual port numbering (for 100Gbps interfaces):

    show hw-module subslot x/0 port-group mapping

    show hw-module subslot x/0 port-group operation-mode

    show hw-module subslot x/0 port-group port-numbering

    where x is the Linecard slot number.

    Sample Output:


    Switch#show hw-module subslot 1/0 port-group mapping 
    Port Group Mapping for slot 1

    Limitations with CVR-QSFP-SFP10G Adaptor

    • CVR-QSFP-SFP10G adapter must not be installed on an even-numbered port where the corresponding odd-numbered port has 40GE optics. For example, if port 1 has 40GE optics, CVR-QSFP-SFP10G must not be installed in port 2.

    • CVR-QSFP-SFP10G adapter must not be installed on any port that has an enable config. For example, CVR-QSFP-SFP10G adapter must not be installed on a port configured to operate in 100GE.
