permit
To permit packets from a specic source IP address to leave the switch, congure a lter.
Syntax
permit {source [mask]| any | host ip-address} [no-drop]
To remove this lter, you have two choices:
• Use the no seq sequence-number command if you know the lter’s sequence number.
• Use the no permit {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 /prex format (/x) or A.B.C.D. The mask,
when specied 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 lter. You can
enter any of the following keywords to specify route types.
• bytes — Enter the keyword bytes to count bytes processed by the lter.
• count — Enter the keyword count to count packets the lter processes.
• dscp — Enter the keyword dcsp to match to the IP DCSCP values.
• fragments — Enter the keyword fragments to match to non-initial
fragments of a datagram.
• order — 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).
host ip-address Enter the keyword host then the IP address to specify a host IP address or
hostname.
no-drop Enter the keywords no-drop to match only the forwarded packets.
Defaults Not congured.
