Deny Udp (For Ipv6 Acls) - Dell S4810 Reference Manual

ingress and egress interfaces are examined and, appropriate ACLs can be applied in
both the ingress and egress direction. Flow-based monitoring conserves
bandwidth by monitoring only specified traffic instead all traffic on the interface.
This feature is particularly useful when looking for malicious traffic. It is available for
Layer 2 and Layer 3 ingress and egress traffic. You may specify traffic using
standard or extended access-lists. This mechanism copies all incoming or outgoing
packets on one port and forwards (mirrors) them to another port. The source port
is the monitored port (MD) and the destination port is the monitoring port (MG).

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:
•
•
Parameters
log
threshold-in
msgs count
interval
minutes
monitor
Defaults By default, 10 ACL logs are generated if you do not specify the threshold explicitly.
The default frequency at which ACL logs are generated is five minutes. By default,
flow-based monitoring is not enabled.
Command ACCESS-LIST
Modes
Access Control Lists (ACL)
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
(OPTIONAL) Enter the keyword log to enable the triggering
of ACL log messages.
(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.
(OPTIONAL) Enter the keyword interval followed by the
time period in minutes at which ACL logs must be generated.
The threshold range is from 1 to 10 minutes.
(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.
