DES-3028 DES-3028P DES-3028G DES-3052 DES-3052P Layer 2 Fast Ethernet Managed Switch
Des
tination IP Mask
Enter an IP address mask for the destination IP address.
DSCP
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.
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 Messages Protocol (ICMP)
field in each frame's header.
Select IGMP to instruct the Switch to examine the Internet Group Management Protocol
(IGMP) field in each frame's header.
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 mask - Enter a value defining the protocol ID in the packet header to mask. Specify
in hex form (hex 0x0-0xf).
The window shown below is the Access Profile Configuration window for Packet Content Mask.
