Hi all,

I have Solaris 8 system with two-network interface configured. ce0 & ce4. ce4
has host IP address, ce0 has backup network IP address. When system comes up
ce4 interface gets wrong netmask (255.255.0.0).

I have to run ifconfig command to correct this problem..

Ifconfig ce4 netmask 255.255.254.0

I would like to know why its picking up wrong netmak and how to resolve it.

/etc/inet/netmasks

172.31.215.0 255.255.254.0

172.31.199.0 255.255.255.0

ifconfig output

ce0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2

        inet 172.31.199.231 netmask ffffff00 broadcast 172.31.199.255

ce4: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3

        inet 172.31.215.231 netmask ffff0000 broadcast 172.31.215.255

Thanks

Sundaram
