White Papers

tcp Enter the keyword tcp to filter the Transmission Control protocol.
udp Enter the keyword udp to filter the User Datagram Protocol.
count (OPTIONAL) Enter the keyword count to count packets the filter processes.
byte (OPTIONAL) Enter the keyword byte to count bytes the filter processes.
dscp (OPTIONAL) Enter the keyword dcsp to match to the IP DCSCP values.
order (OPTIONAL) Enter the keyword order to specify the QoS priority for the ACL
entry. The range is from 0 to 254 (where 0 is the highest priority and 254 is the
lowest; lower-order numbers have a higher priority). If you do not use the keyword
order, the ACLs have the lowest order by default (255).
fragments Enter the keyword fragments to use ACLs to control packet fragments.
log OPTIONAL) Enter the keyword log to enable the triggering of ACL log messages.
threshold-in-
msgs
(OPTIONAL) Enter the threshold-in-msgs keyword followed by a value to
indicate the maximum number of ACL logs that can be generated, exceeding
which the generation of ACL logs is terminated with the seq, permit, or deny
commands. The threshold range is from 1 to 100.
interval minutes (OPTIONAL) Enter the keyword interval followed by the time period in minutes at
which ACL logs must be generated. The interval range is from 1 to 10 minutes.
monitor (OPTIONAL) Enter the keyword monitor when the rule is describing the traffic
that you want to monitor and the ACL in which you are creating the rule is applied
to the monitored interface.

deny udp (for IPv6 ACLs)
Configure a filter to drop user datagram protocol (UDP) packets meeting the filter criteria.
Syntax
deny udp {source address mask | any | host ipv6-address} [operator port
[port]] {destination address | any | host ipv6-address} [operator port
[port]] [count [byte]] [log [interval minutes] [threshold-in-msgs [count]]
[monitor]
To remove this filter, you have two choices:
● Use the no seq sequence-number command syntax if you know the filter’s sequence number
● Use the no deny udp {source address mask | any | host ipv6-address}
{destination address | any | host ipv6-address} command
Parameters
source Enter the IP address of the network or host from which the packets are sent.
mask 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.
any
Enter the keyword any to specify that all routes are subject to the filter.
