Configuring Switch Information 197
• Source IP Address—Matches the source IP address to which packets are addressed to
the ACE.
• Wild Card Mask—Indicates the source IP Address wild card mask. Wild cards are
used to mask all or part of a source IP Address. Wild card masks specify 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 00.00.00.00 indicates that all bits are important. For
example, if the source IP address 149.36.184.198 and the wildcard mask is
255.36.184.00, the first two bits of the IP address are ignored, while the last two bits
are used.
• Dest. IP Address—Matches the destination IP address to which packets are addressed
to the ACE.
• Wild Card Mask—Indicates the destination IP Address wild card mask. Wild cards are
used to mask all or part of a destination IP Address. Wild card masks specify 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 00.00.00.00 indicates that all bits are important.
For example, if the destination IP address 149.36.184.198 and the wildcard mask is
255.36.184.00, the first two bits of the IP address are used, while the last two bits are
ignored.
• Match DSCP—Matches the packet DSCP value to the ACE. Either the DSCP value
or the IP Precedence value is used to match packets to ACEs.
• Match IP-Precedence—Matches the packet IP Precedence value to the ACE. Either
the DSCP value or the IP Precedence value is used to match packets to ACEs.
• Action—Indicates the ACE forwarding action. The possible field values are:
– Permit—Forwards packets which meet the ACE criteria.
– Deny—Drops packets which meet the ACE criteria.
– Deny and Disable Port—Drops packet that meet the ACE criteria, and disables
the port to which the packet was addressed. Ports are reactivated from the Port
Configuration; see "Defining Port Parameters".
