VLAN 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.
Source IP Mask Enter an IP address mask for the source IP address.
Destination IP 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 Message 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 specification of a source port mask and/or a destination port
mask. 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).
Select UDP to use the UDP port number contained in an incoming packet as the forwarding
criterion. Selecting UDP requires specification of a source port mask and/or a destination port
mask.
protocol id - Enter a value defining the protocol ID in the packet header to mask. Specify the
protocol ID mask in hex form (hex 0x0-0xffffffff).
