The S-Series cannot count both packets and bytes, so when you enter the count byte options, only
bytes are incremented..

Commands
deny icmp
z
Configure a filter to drop all or specific ICMP messages.
Syntax
deny icmp {source mask | any | host ip-address} {destination mask | any | host ip-address}
[dscp] [count [byte]] [order] [fragments]
To remove this filter, you have two choices:
• Use the no seq sequence-number command syntax if you know the filter’s sequence number or
• Use the no deny icmp {source mask | any | host ip-address} {destination mask | any |
host ip-address} command.

any Enter the keyword any to specify that all routes are subject to the filter.
host ip-address Enter the keyword host followed by the IP address to specify a host IP address.
destination

dscp
Enter this keyword to deny a packet based on DSCP value.
Range: 0-63
count (OPTIONAL) Enter the keyword count to count packets processed by the filter.
byte (OPTIONAL) Enter the keyword byte to count bytes processed by the filter.
order (OPTIONAL) Enter the keyword order to specify the QoS priority for the ACL
entry.
Range: 0-254 (where 0 is the highest priority and 254 is the lowest; lower order
numbers have a higher priority)
Default: If the order keyword is not used, the ACLs have the lowest order by default
(255).
fragments Enter the keyword fragments to use ACLs to control packet fragments.
