deny (for Standard IP ACLs)
To drop packets with a certain IP address, configure a filter.
Syntax
deny {source | any | host {ip-address}}[count [byte]] [dscp
value] [order] [fragments] [log [interval minutes] [threshold-
in-msgs [count]] [monitor]
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 {source [mask] | any | host ip-address}
command.
Parameters
source Enter the IP address of the network or host from which the
packets were sent.
any Enter the keyword any to specify that all routes are subject
to the filter.
host ip-address Enter the keyword host then the IP address to specify a host
IP address.
count (OPTIONAL) Enter the keyword count to count packets
processed by the filter.
byte (OPTIONAL) Enter the keyword byte to count bytes
processed by the filter.
dscp Enter this keyword dscp to deny a packet based on the
DSCP value. The range is from 0 to 63.
log (OPTIONAL) Enter the keyword log to enable the triggering
of ACL log messages.
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 did 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.
threshold-in
msgs count
(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.
