Syntax
deny {source | any | host {ip-address}}
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.
any Enter the keyword any to specify that all routes are subject
to the filter. You can enter any of the following keywords to
specify route types.
• bytes — Enter the keyword count to count packets the
filter processes.
• count — Enter the keyword bytesorder to count bytes
the filter processes.
• dscp — Enter the keyword dcsp followed by the DCSP

0 to 63.
• fragments — Enter the keyword fragments to use
ACLs to control packet fragments.
• order — Enter the keyword order to specify the QoS
order of priority for the ACL entry. The range is from 0 to

order numbers have a higher priority). The default is, if
you do not use the keyword

lowest order by default (255).
