bad mask /24 for address

Why can't I add this address to int vlan 10?

int vlan 10

ip address 10.1.10.0 255.255.255.0

result is "Bad mask /24 for address 10.1.10.0"

I added "ip subnet-zero" and it still won't work. Any ideas? This is a 4506 with a Sup4.

Thanks,

Patrick

Re: bad mask /24 for address

The valid range for the /24 is 10.1.10.1-254. 10.1.10.0 is your network address and 10.1.10.255 is the broadcast address.

Hope this help,

It´s a trivial issue because

It´s a trivial issue because we usually set the network address instead of port address.

  • 10.1.10.0  network address.
  • 10.1.10.1 port address
