Standard IP ACL Commands
When you create an ACL without any rule and then apply it to an interface, the ACL behavior reflects an implicit permit.
The C-Series and S-Series platforms (except the S4810) support Ingress IP ACLs only.
The S4810 and Z9000 support both Ingress and Egress IP ACLs.
NOTE: Also refer to the Commands Common to all ACL Types and Common IP ACL Commands sections.
deny
Configure a filter to drop packets with a certain IP address.
C-Series, E-Series, S-Series, Z-Series, S4810
Syntax deny { source [ mask ] | any | host ip-address } [count [byte] |
log] [dscp value ] [order] [monitor] [fragments]
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 in dotted decimal format of the network from
which the packet was sent.
mask (OPTIONAL) 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 (discontiguous).
any Enter the keyword
any
to specify that all routes are subject to the
filter.
host
ip-address
Enter the keyword
host
and then enter the IP address to specify a
host IP address only.
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.
log (OPTIONAL, E-Series only) Enter the keyword
log
to enter ACL
matches in the log.
dscp (OPTIONAL) Enter the keyword
dcsp
to match to the IP DCSCP
values.
order (OPTIONAL) Enter the keyword
order
to specify the QoS order of
priority for the ACL entry. The range is 0 to 254 (where 0 is the highest
priority and 254 is the lowest; lower order numbers have a higher
priority). The default is, if you do not use the keyword
order
, the
ACLs have the lowest order by default (255).
