Output of "dbget :cluster_ip:interface:IF_NAME" command on cluster member returns wrong subnet mask
Symptoms
  • Output of "dbget :cluster_ip:interface:<IF_NAME>" command on cluster member returns wrong CIDR subnet mask.

    Example:

    1. On a cluster interface, define an IP address (X.X.X.X) in subnet with CIDR=29 (255.255.255.248)
    2. Install policy
    3. On cluster member, run the command:
      [Expert@HostName:0]# dbget :cluster_ip:interface:<IF_NAME>
    4. The output shows X.X.X.X/0 instead of X.X.X.X/29
  • Output of "ifconfig" command does not show Broadcast address and Subnet Mask.

    Example:

    eth1        Link encap:Ethernet  HWaddr XX:XX:XX:XX:XX:XX 
                inet addr:192.168.191.134  Bcast:  Mask: 
    
Cause

Incorrect calculation of CIDR from network mask.
