| Destination IP Mask |
| Enter an IP address mask for the destination IP address. |
|
| Protocol |
| Selecting this option instructs the Switch to examine the protocol type value in each frame's |
|
|
|
| header. You must then specify what protocol(s) to include according to the following |
|
|
|
| guidelines: |
|
|
|
| Select ICMP to instruct the Switch to examine the Internet Control Message Protocol (ICMP) |
|
|
|
| field in each frame's header. |
|
|
|
| Select Type to further specify that the access profile will apply an ICMP type value, or |
|
|
|
| specify Code to further specify that the access profile will apply an ICMP code |
|
|
|
| value. |
|
|
|
| Select IGMP to instruct the Switch to examine the Internet Group Management Protocol |
|
|
|
| (IGMP) field in each frame's header. |
|
|
|
| Select Type to further specify that the access profile will apply an IGMP type value. |
|
|
|
| Select TCP to use the TCP port number contained in an incoming packet as the forwarding |
|
|
|
| criterion. Selecting TCP requires a source port mask and/or a destination port mask is to be |
|
|
|
| specified. The user may also identify which flag bits to filter. Flag bits are parts of a packet |
|
|
|
| that determine what to do with the packet. The user may filter packets by filtering certain flag |
|
|
|
| bits within the packets, by checking the boxes corresponding to the flag bits of the TCP field. |
|
|
|
| The user may choose between urg (urgent), ack (acknowledgement), psh (push), rst (reset), |
|
|
|
| syn (synchronize), fin (finish). |
|
|
|
| src port mask – Specify a TCP port mask for the source port in hex form (hex |
|
|
|
| which you wish to filter. |
|
|
|
| dst port mask – Specify a TCP port mask for the destination port in hex form (hex 0x0- |
|
|
|
| 0xffff) which you wish to filter. |
|
|
|
| Select UDP to use the UDP port number contained in an incoming packet as the forwarding |
|
|
|
| criterion. Selecting UDP requires that you specify a source port mask and/or a destination |
|
|
|
| port mask. |
|
|
|
| src port mask – Specify a UDP port mask for the source port in hex form (hex |
|
|
|
| dst port mask – Specify a UDP port mask for the destination port in hex form (hex 0x0- |
|
|
|
| 0xffff). |
