Lists the destination address of the packet and the name of the interface (in parentheses) through which the packet is being sent out on the network. Displays the packet's length. The last part of each line lists the status of the packet. Displays the source and destination ports, the sequence number, the acknowledgement number, and the window size of the packets in that TCP packets. Displays the source and destination ports for the UDP packets. Displays the ICMP type and code. States that it is a fragment and displays the unique number identifying the fragment (Ident) and the offset (in 8-byte units) of this fragment (fragment offset) from the beginning of original datagram. Usage Information Use the count option to stop packets from flooding the user terminal when debugging is turned on. The access-group option supports only the equal to (eq) operator in TCP ACL rules. Port operators not equal to (neq), greater than (gt), less than (lt), or range are not supported in access-group option (see Figure 24-4). ARP packets (arp) and Ether-type (ether-type) are also not supported in access-group option. The entire rule is skipped to compose the filter. The access-group option pertains to: • IP Protocol Number 0 to 255 642 | IPv4 Routing
