● show config — display the current configuration.
permit
To pass IP packets meeting the filter criteria, configure a filter.
Syntax
permit {source mask | any | host ip-address} {destination mask | any | host
ip-address} [ttl operator] [count [bytes]] [dscp value] [order] [fragments]
[monitor] [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 deny {source mask | any | host ip-address} {destination 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.
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 or
hostname.
destination Enter the IP address of the network or host to which the packets are sent.
ttl Enter the keyword ttl to permit a packet based on the time to live value. The
range is from 1 to 255.
operator Enter one of the following logical operand:
● eq(equal to) — matches packets that contain a ttl value that is equal to the
specified ttl value.
● neq(not equal to) — matches packets that contain a ttl value that is not equal
to the specified ttl value.
● gt(greater than) — matches packets that contain a ttl value that is greater
than the specified ttl value.
● lt (less than) — matches packets that contain a ttl value that is less than the
specified ttl value.
● range(inclusive range of values) — matches packets that contain a ttl value
that falls between the specified range of ttl values.
count (OPTIONAL) Enter the keyword count to count packets processed by the filter.
bytes (OPTIONAL) Enter the keyword bytes to count bytes processed by the filter.
dscp (OPTIONAL) Enter the keyword dcsp to match to the IP DCSCP values.
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 do 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.
monitor (OPTIONAL) Enter the keyword monitor to describe the traffic that you want
to monitor and the ACL in which you are creating the rule is applied to the
monitored interface. For more information, see “Flow-based Monitoring” in the Port
Monitoring section of the Dell EMC Networking OS Configuration Guide.
no-drop Enter the keywords no-drop to match only the forwarded packets.
Defaults Not configured.
