Usage
Information
The order option is relevant in the context of the Policy QoS feature only. For more information, see the
“Quality of Service” section of the Dell Networking OS Configuration Guide.
The software cannot count both packets and bytes; when you enter the count byte options, only bytes
are incremented.

Commands
● ip access-list extended — create an extended ACL.
●
● permit tcp — assign a permit filter for TCP packets.
● permit udp — assign a permit filter for UDP packets.
permit tcp
To pass TCP packets meeting the filter criteria, configure a filter.
Syntax
permit tcp {source mask | any | host ip-address} [bit] [operator port
[port]] {destination mask | any | host ip-address} [bit] [dscp] [operator
port [port]] [count [byte] [order] [fragments] [no-drop]
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 permit tcp {source mask | any | host ip-address} {destination
mask | any | host ip-address} command.
Parameters
source Enter the IP address of the network or host from which the packets were sent.
mask 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.
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.
