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.
Enter an IP address mask for the source IP address.
Enter an IP address mask for the destination IP address.
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.
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 that you specify a source port mask and/or a destination port
mask. The user may also identify which flag bits to deny. Flag bits are parts of a packet that
determine what to do with the packet. The user may deny packets by denying 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 deny.
dest port mask - Specify a TCP port mask for the destination port in hex form (hex
•
0x0-0xffff) which you wish to deny.
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 TCP port mask for the source port in hex form (hex 0x0-
•
0xffff).
dest port mask - Specify a TCP port mask for the destination port in hex form (hex
•
0x0-0xffff).
protocol id - Enter a value defining the protocol ID in the packet header to mask. Specify up to
5, Layer 4 port masks for the destination port in hex form (hex 0x0-0xffffffff).
