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] To remove this filter, you have two choices: • 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. Parameters source mask any host ip-address dscp operator 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 to 63. (OPTIONAL) Enter one of the following logical operand: • eq = equal to • neq = not equal to • gt = greater than • lt = less than • range = inclusive range of ports (you must specify two ports for the port command) port port Enter the application layer port number. Enter two port numbers if using the range logical operand. The range is from 0 to 65535. 216 Access Control Lists (ACL)
