permit icmp
Configures a filter to permit all or specific ICMP messages.
Syntax
permit icmp [A.B.C.D | A.B.C.D/x | any | host ip-address] [[A.B.C.D |
A.B.C.D/x | any | host ip-address] [capture | count | dscp value | fragment
| log]
Parameters
● A.B.C.D — Enter the IPv4 address in dotted decimal format.
● A.B.C.D/x — Enter the number of bits that must match the dotted decimal address.
● any — (Optional) Enter the keyword any to specify any source or destination IP address.
● host ip-address — (Optional) Enter the IPv4 address to use a host address only.
● capture — (Optional) Capture packets the filter processes.
● count — (Optional) Count packets the filter processes.
● byte — (Optional) Count bytes the filter processes.
● dscp value — (Optional) Permit a packet based on the DSCP values, from 0 to 63.
● fragment — (Optional) Use ACLs to control packet fragments.
● log — (Optional) Enables ACL logging. Information about packets that match an ACL rule are logged.
Default Not configured
Command Mode IPV4-ACL
Usage
Information
OS10 cannot count both packets and bytes; when you enter the count byte options, only bytes
increment. The no version of this command removes the filter.
Example
OS10(config)# ip access-list testflow
OS10(conf-ipv4-acl)# permit icmp any any capture session 1
Supported
Releases
10.2.0E or later
permit icmp (IPv6)

Syntax
permit icmp [A::B | A::B/x | any | host ipv6-address] [A::B | A:B/x | any |
host ipv6-address] [capture | count | dscp value | fragment | log]
Parameters
● A::B — Enter the IPv6 address in hexadecimal format separated by colons.
● A::B/x — Enter the number of bits that must match the IPv6 address.
● any — (Optional) Enter the keyword any to specify any source or destination IP address.
● host ipv6-address — (Optional) Enter the IPv6 address to use a host address only.
● capture — (Optional) Capture packets the filter processes.
● count — (Optional) Count packets the filter processes.
● byte — (Optional) Cunt bytes the filter processes.
● dscp value — (Optional) Permit a packet based on the DSCP values, from 0 to 63.
