D-Link DES-3250TG Standalone Layer 2 Switch Dscp Ethernet type (for Ethernet Access Profiles only) Protocol (for IP address Access Profiles only) 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. Selecting this option instructs the switch to examine the Ethernet type value in each frame's header. 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 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. 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). 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 81

D-Link DES-3250TG Standalone Layer 2 Switch
each packet header and use this as the,
or part of the criterion for forwarding.
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.
Ethernet type
(for Ethernet
Access Profiles
only)
Selecting this option instructs the switch
to examine the Ethernet type value in
each frame’s header.
Protocol
(for IP address
Access Profiles
only)
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 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.
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).
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
