IPv6 issue with Port-Channel

Hello All,

I am unable to enable ipv6 on port-channel and the interfaces that are part of port-channel. But its enabling IPv6 on the single interfaces that are not part of the port channel. 

I am using OS10 with switch Dell S5232-ON. Below is screenshots of the issues. 

 

Interface (which is part of port-channel) output :

    Hello, 

    Can you try like as below;

     

    pg 895  https://dl.dell.com/topicspdf/dell-emc-smartfabric-os10_users-guide13_en-us.pdf

     

    • IPv6 forwarding is enabled on physical Ethernet interfaces, VLANs, and port groups. IPv6 forwarding is disabled only when you enable IPv6 address autoconfiguration on an interface and set it in host mode using the ipv6 address autoconfig command.
    • IPv6 forwarding is permanently disabled on the management Ethernet interface so that it remains in Host mode and does not operate as a router regardless of the ipv6 address autoconfig setting.

    If necessary, you can manually disable IPv6 processing on an interface so that the configured IPv6 addresses do not take effect. The IPv6 addresses take effect again when you re-enable IPv6.

    If you disable IPv6 and configure a Layer (L2) interface in Layer (L3) mode, IPv6 is not automatically re-enabled on the interface. You must manually re-enable it.

    A link-local address automatically generates when you re-enable IPv6 on an interface with the ipv6 enable command.

    Disable and enabIe IPv6

    OS10(config)# interface ethernet 1/1/8
OS10(conf-if-eth1/1/8)# ipv6 address 2111:dddd:0eee::22/64
OS10(conf-if-eth1/1/8)# no ipv6 address autoconfig
OS10(conf-if-eth1/1/8)# no ipv6 enable
OS10(conf-if-eth1/1/8)# ipv6 enable
