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
❑ URG - Urgent
❑ ACK - Acknowledgement
❑ RST - Reset
❑ PSH - Push
❑ SYN - Synchronization
❑ FIN - Finish
