The S-Series cannot count both packets and bytes, so when you enter the count byte options, only bytes are incremented.. Note: When ACL logging and byte counters are configured simultaneously, byte counters may display an incorrect value. Configure packet counters with logging instead. Related Commands deny tcp deny udp ip access-list extended Assign a filter to deny TCP packets. Assign a filter to deny UDP packets. Create an extended ACL. deny icmp z S6000 Configure a filter to drop all or specific ICMP messages.

Parameters source mask any host ip-address destination dscp count byte order fragments Enter the IP address of the network or host from which the packets were sent. 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 non-contiguous. Enter the keyword any to specify that all routes are subject to the filter. Enter the keyword host followed by the IP address to specify a host IP address.
