address {ip_address ip_mask | ip_address/bitmask} [ secondary | srp-activate ]
Configures the IP address and network mask for the interface.
Enter an
Enter an
ip_address ip_mask
to specify an IP address and the subnet mask pair that identifies the IP
address of the interface.
ip_address
is entered in IPv4 dotted-decimal or IPv6 colon-separated-hexadecimal
notation. Currently, the only value accepted for
ip_mask
is 255.255.255.255 (IPv4) or 120 (IPv6) .
For the network mask,
ip_address/net_mask
, enter the IP address and the length in bits of the network
mask, For example, 192.168.1.0/32 (IPv4) or fe80::c0a8:100/32 (IPV6). Currently, the only value accepted
for bit_mask is 32.
