  • Network OS
  • VDX series
  • VRRP
This issue is observed only when an invalid address 0.XXX/X is entered on the switch.  
The cli leads to DCMD termination instead of blocking it with "invalid Ip address/mask" informational message to user.
  • Workaround
    • Do not use as it is not valid address.
  • Permanent Solution
    • Upgrade to NOS 7.1.0a, 7.0.2a, 7.2.0 or any release that has the fix for DEFECT000633219
