WRP interfaces and associated routes disappear from Virtual Systems on VSX with Kernel 3.10 Technical Level
Symptoms
  • No WRP interface is seen on VS's on VSX with Kernel 3.10.
    This can be checked with the command:
    # for i in `cpstat vsx -f stat | grep "Virtual System" | cut -f 2 -d "|"`; do vsenv $i; ifconfig | grep wrp; done; vsenv 0

    Note: On R80.40 run:

    # for i in `vsx stat -v | egrep -v "Not Applicable|SIC"| grep Trust| awk '{print $1}'`; do vsenv $i; ifconfig | grep wrp; done; vsenv 0

  • No routes relevant for WRP interfaces are seen on VS's on VSX with Kernel 3.10
    This can be checked with the command:
    # for i in `cpstat vsx -f stat | grep "Virtual System" | cut -f 2 -d "|"`; do vsenv $i; route -n; done; vsenv 0

    Note: On R80.40 run:

    # for i in `vsx stat -v | egrep -v "Not Applicable|SIC"| grep Trust| awk '{print $1}'`; do vsenv $i; route -n; done; vsenv 0
