User Specified IP Protocol
Defines a traffic flow of a Layer 3 protocol by its protocol number. The
number can be entered in either decimal or hexadecimal format. If you
use the latter, precede the number with “0x”. To set this parameter, the
IP Protocol parameter must be set to User Specified.
Source IP Address
Source IP Mask
Defines a traffic flow by a source IP address. The address can be of a
specific node or a subnet.
You do not need to include a source IP mask if you are filtering on the
IP address of a specific end node. A mask is required, however, when
filtering on a subnet. A binary “1” indicates the switch should filter on
the corresponding bit of the IP address, while a “0” indicates that it
should not. For example, the Class C subnet address 149.11.11.0
would have the mask “255.255.255.0”.
Destination IP Address
Destination IP Mask
Defines a traffic flow by its destination IP address. The address can be
of a specific node or a subnet.
You do not need to include a source IP mask if you are filtering on the
IP address of a specific end node. A mask is required, however, when
filtering on a subnet. A binary “1” indicates the switch should filter on
the corresponding bit of the IP address, while a “0” indicates that it
should not. For example, the Class C subnet address 149.11.11.0
would have the mask “255.255.255.0”.
TCP Source Port
Defines a traffic flow by source TCP port. To set this parameter, IP
Protocol must be set to TCP.
TCP Destination Port
Defines a traffic flow by destination TCP port. To set this parameter, IP
Protocol must be set to TCP.
TCP Flags
Defines a traffic flow by TCP flag. To set this parameter, IP Protocol
must be set to TCP. Options are
ˆ URG - Urgent
ˆ ACK - Acknowledgement
ˆ RST - Reset
ˆ PSH - Push
ˆ SYN - Synchronization
ˆ FIN - Finish
