Description
Type in a unique identifier number for this access. This value can be set from 1 to 5.
Selecting this option instructs the Switch to examine the DiffServ Code part of each packet
header and use this as the criteria, or part of the criterion for forwarding.
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.
Select the option and enter the Source IP Address or the Destination IP Address. This will
be used as the criteria for forwarding decisions.
Tick IGMP to instruct the Switch to examine the Internet Group Management Protocol
(IGMP) field in each frame's header.
Tick IGMP Type to further specify that the access profile will apply an IGMP type value.
Tick TCP to use the TCP port number contained in an incoming packet as the forwarding
criterion. Ticking TCP requires specifying 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.
Tick UDP to use the UDP port number contained in an incoming packet as the forwarding
criterion. Ticking UDP requires specifying a source port mask and/or a destination port
mask.
Select ICMP to instruct the Switch to examine the Internet Control Message Protocol (ICMP)
field in each frame's header.
Select Permit to specify that the packets that match the access profile are forwarded by the
Switch, according to any additional rule added (see below).
Select Deny to specify the packets that match the access profile are not forwarded by the
Switch and will be filtered.
Tick the check box and enter the name of the Time Range settings that has been previously
configured in the Time Range Settings window. This will set specific times when this
access rule will be implemented on the Switch.
Enter a range of ports to be configured.
