Z9500
Syntax permit icmp {source mask | any | host ip-address} {destination
mask | any | host ip-address} [dscp] [count [bytes]] [order]
[fragments] [log [interval minutes] [threshold-in-msgs [count]]
[monitor]
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.
dscp Enter the keyword dscp to deny a packet based on the
DSCP value. The range is 0 to 63.
count (OPTIONAL) Enter the keyword count to count packets the
filter processes.
bytes (OPTIONAL) Enter the keyword byte to count bytes the filter
processes.
order (OPTIONAL) Enter the keyword order to specify the QoS
priority for the ACL entry. The range is 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.
log (OPTIONAL) Enter the keyword log to include ACL
messages in the log.
