General Routing

  • Channelized interfaces leds are not properly represented in show chassis led.PR1720502

  • Problem: Performing VC split and Merge operation causes traffic to be affected for Broadcast, Unknown-unicast and Multicast traffic. RCA: When the link is brought down, each FPC will try to re-synchronize the IFDs, in addition resources are busy with updating for the new role. This can cause some synchronization issues with for IFDs/IFLs and other such lists. Test: This can be seen by the VTY command show ifd brief and show ifl brief for all the FPCs Workaround: It is recommended to wait at least 240 seconds after splitting the VC ad merging it back again. This ensures that the system can get enough time to synchronize the IFDs/IFLs etc. from the kernel.PR1867979
