header.
Selecting this option instructs the Switch to examine the VLAN part of each packet
header and use this as the, or part of the criterion for forwarding.
Selecting this option instructs the Switch to examine the DiffServ Code part of each
packet header and use this as the, or part of the criterion for forwarding.
Enter an IP address mask for the source IP address, e.g. 255.255.255.255.
Enter an IP address mask for the destination IP address, e.g. 255.255.255.255.
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 0x0-
0xffff), 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 0x0-
0xffff).
dst port mask - Specify a UDP port mask for the destination port in hex form (hex 0x0-
0xffff).
Select Protocol ID - Enter a value defining the protocol ID in the packet header to
mask. Specify the protocol ID mask in hex form (hex 0x0-0xff).
Protocol ID Mask – Specify that the rule applies to the IP Protocol ID Traffic.
User Define – Specify the L4 part mask.
