deny icmp
Congures a lter to drop all or specic Internet Control Message Protocol (ICMP) messages.
Syntax
deny 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 IP address in hexadecimal format separated by colons.
• A.B.C.D/x — Enter the number of bits to match to the IP address.
• any — (Optional) Enter the keyword any to specify any source or destination IP address.
• host ip-address — (Optional) Enter the IP address to use a host address only.
• capture — (Optional) Capture packets the lter processes.
• count — (Optional) Count packets the lter processes.
• byte — (Optional) Count bytes the lter processes.
• dscp value — (Optional) Deny 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 congured
Command Mode IPV4-ACL
Usage Information OS10 cannot count both packets and bytes; when you use the count byte options, only bytes increment. The
no version of this command removes the lter.
The count, byte, and log options are not supported on the S5148F-ON platform.
Example
OS10(config)# ip access-list egress
OS10(conf-ipv4-acl)# deny icmp any any capture session 1
Supported Releases 10.2.0E or later
deny icmp (IPv6)
Congures a lter to drop all or specic ICMP messages.
Syntax
deny 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 to match to 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.
