To drop user datagram protocol (UDP) packets meeting the filter criteria, configure a filter.
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] [monitor [session-ID]] [no-drop]

deny — assign a filter to deny IP traffic.
deny udp — assign 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.
Enter the keyword any to specify that all routes are subject to the filter.
Enter the keyword host then the IP address to specify a host IP address.
Enter this keyword dscp to deny a packet based on the DSCP value. The range is from 0
