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 icmp
Configure a filter to allow all or specific ICMP messages.
Syntax
permit icmp {source mask | any | host ip-address} {destination mask | any |
host ip-address} [type] [dscp] [message-type] [count [byte] | log] [order]
[monitor] [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 icmp {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 noncontiguous.
any Enter the keyword any to match and drop specific Ethernet traffic on the
interface.
host ip-address Enter the keyword host and then enter the IP address to specify a host IP
address.
destination Enter the IP address of the network or host to which the packets are sent.

For IPv4:
echo count
