Table 213: IP ACL Rule Configuration Fields (Cont.)
Description
Requires a packet's source port IP address to match the address listed here.
Click Configure, and then enter an IP Address in the appropriate field using
dotted-decimal notation. The address you enter is compared to a packet's
source IP Address. You also configure the Source IP Mask on the page.
Specifies the source IP address wildcard mask. Wild card masks determines
which bits are used and which bits are ignored. A wild card mask of
255.255.255.255 indicates that no bit is important. A wildcard of 0.0.0.0
indicates that all of the bits are important. Wildcard masking for ACLs
operates differently from a subnet mask. A wildcard mask is in essence the
inverse of a subnet mask. With a subnet mask, the mask has ones (1's) in the
bit positions that are used for the network address, and has zeros (0's) for the
bit positions that are not used. In contrast, a wildcard mask has (0's) in a bit
position that must be checked. A '1' in a bit position of the ACL mask indicates
the corresponding bit can be ignored. This field is required when you
configure a source IP address. After you enter the desired information for the
Source IP Address and Source IP Mask, click Submit or Cancel to return to the
Rule Configuration page.
Requires a packet's TCP/UDP source port to match the port listed here. Click
Configure access the configuration page, then complete one of the following
fields:
• Source L4 Keyword: Select the desired L4 keyword from a list of source
ports on which the rule can be based. If you select a keyword other than
Other, the screen refreshes and the Source L4 Port Number field
disappears.
• Source L4 Port Number: If the source L4 keyword is Other, enter a user-
defined Port ID by which packets are matched to the rule.
Requires a packet's destination port IP address to match the address listed
here. Click Configure, and then enter an IP Address in the appropriate field
using dotted-decimal notation. The address you enter is compared to a
packet's destination IP Address. You also configure the Destination IP Mask on
the page.
Specify the IP mask in dotted-decimal notation to be used with the
Destination IP Address value.
Requires a packet's TCP/UDP destination port to match the port listed here.
Click Configure access the configuration page, then complete one of the
following fields:
• Destination L4 Keyword: Select the desired L4 keyword from a list of
destination ports on which the rule can be based. If you select a keyword
other than Other, the screen refreshes and the Destination L4 Port
Number field disappears.
• Destination L4 Port Number: If the destination L4 keyword is Other, enter
a user-defined Port ID by which packets are matched to the rule. The valid
range is 0 to 65535.
