deny icmp (IPv6)
Configures a filter to drop all or specific 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.
• capture — (Optional) Capture packets the filter processes.
• count — (Optional) Count packets the filter processes.
• byte — (Optional) Count bytes the filter 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 configured
Command Mode IPV6-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 filter.
Example
OS10(config)# ipv6 access-list ipv6test
OS10(conf-ipv6-acl)# deny icmp any any capture session 1

deny ip
Configures a filter to drop all or specific packets from an IPv4 address.
Syntax
deny ip [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 [byte] | dscp value | fragment]
Parameters
• A.B.C.D — Enter the IPv4 address in dotted decimal format.
• A.B.C.D/x — Enter the number of bits to match to the dotted decimal address.
• any — (Optional) Set all routes which are subject to the filter:
• capture — (Optional) Capture packets the filter processes.
•
count — (Optional) Count packets the filter processes.
• byte — (Optional) Count bytes the filter processes.
• dscp value — (Optional) Deny a packet based on the DSCP values, from 0 to 63.
• fragment — (Optional) Use ACLs to control packet fragments.
• host ip-address — (Optional) Enter the IPv4 address to use a host address only.
Default Not configured
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 filter.
Example
OS10(config)# ip access-list testflow
OS10(conf-ipv4-acl)# deny ip any any capture session 1 count
