Deny Udp - Dell S6000 Reference Manual

range of ports is configured in the CAM based on bit mask boundaries; the space
required depends on exactly what ports are included in the range.
Example
An ACL rule with a TCP port range of 4000–8000 uses eight entries in the CAM.

S6000
Syntax
deny udp {source mask | any | host ip-address} [operator port
[port]] {destination mask | any | host ip-address} [dscp]
[operator port [port]] [count [byte] [order] [fragments]
To remove this filter, you have two choices:

Data
— assigns a filter to deny IP traffic.
— assigns a filter to deny UDP traffic.
Use the no seq sequence-number command if you know the filter's
sequence number.
Use the no deny udp {source mask | any | host ip-address}
{destination mask | any | host ip-address} command.
Enter the IP address of the network or host from which the
packets were sent.
Enter a network mask in /prefix format (/x) or A.B.C.D. The
mask, when specified in A.B.C.D format, may be either
contiguous or non-contiguous.
