D-Link DWS-1008 CLI Manual 5
MAC Address Notation
MSS displays MAC addresses in hexadecimal numbers with a colon (:) delimiter between bytes—for
example, 00:01:02:1a:00:01. You can enter MAC addresses with either hyphen (-) or colon (:) delimiters,
but colons are preferred.
For shortcuts:
• You can exclude leading zeros when typing a MAC address. MSS displays of MAC addresses
include all leading zeros.
• In some specified commands, you can use the single-asterisk (*) wildcard character to represent
from 1 byte to 5 bytes of a MAC address. (For more information, see “MAC Address Globs” on
page 7.)
IP Address and Mask Notation
MSS displays IP addresses in dotted decimal notation—for example, 192.168.1.11 MSS makes use of
both subnet masks and wildcard masks.
Subnet Masks
Unless otherwise noted, use classless interdomain routing (CIDR) format to express subnet masks—
for example, 192.168.1.112/24. You indicate the subnet mask with a forward slash (/) and specify the
number of bits in the mask.
Wildcard Masks
Security access control lists (ACLs) use source and destination IP addresses and wildcard masks to
determine whether the DWS switch filters or forwards IP packets. Matching packets are either permitted
or denied network access. The ACL checks the bits in IP addresses that correspond to any Os (zeros) in
the mask, but does not check the bits that correspond to Is (ones) in the mask. You specify the wildcard
mask in dotted decimal notation.
For example, the address 10.0.0.0 and mask 0.255.255.255 match all IP addresses that begin with 10
in the first octet.
The ACL mask must be a contiguous set of zeroes starting from the first bit. For example, 0.255.255.255,
0.0.255.255, and 0.0.0.255 are valid ACL masks. However, 0.255.0.255 is not a valid ACL mask.
