2-8 Command Line Interface Commands Reference
preferences output mask { bits | dotted-quad }
show preferences output mask
The preferences output mask command affects the format of the output from those show commands that
display an IP address together with a subnet mask. When set to bits (the default), the IP address and subnet
mask are output in prefix notation – i.e., an IP address in dotted-quad notation followed by a slash followed by
the number of consecutive ones-bits in the subnet mask – whereas when set to dotted-quad, the IP address
and subnet mask are output as two consecutive dotted-quads.
Example:
#preferences output mask bits
#show interface ethernet 0 ip address
interface ethernet 0 ip address 192.168.1.1/24
#preferences output mask dotted-quad
#show interface ethernet 0 ip address
interface ethernet 0 ip address 192.168.1.1 255.255.255.0
