Usage Information

Field

Description

TCP src=

Displays the source and destination ports, the sequence

 

number, the acknowledgement number, and the window

 

size of the packets in that TCP packets.

UDP src=

Displays the source and destination ports for the UDP

 

packets.

ICMP type=

Displays the ICMP type and code.

IP Fragment

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 the original datagram.

To stop packets from flooding the user terminal when debugging is turned on, use the count option.

The access-groupoption 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 (refer to the following example). ARP packets (arp) and Ether-type (ether-type) are also not supported in the access- group option. The entire rule is skipped to compose the filter.

The access-groupoption pertains to:

•IP protocol number: from 0 to 255
