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 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 cod value.
Select IGMP to instruct the Switch to examine the Internet Group Man-

’ s header.
„h * Select type to further specify that the access profile will apply an IGMP

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, a destination port mask or a flag bite.
* 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).
* flag bit - Specify a flag bite in the TCP header.
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 - Specify a TCP port mask for the destination port in hex form
(hex 0x0-0xffffffff).
Port The user may set the Access Profile Table window on a per-port basis by
