The show qcn statistics command is used in the Privileged EXEC mode to show the statistics of the
CNM and the data frames of all the ports or of a specific CP of the given port.
show qcn statistics {slot/port cp-index cp-index}
Parameters
interface slot/port Display CP information for interface in slot/port format.
cp-index cp-index Display the CP index for the interface.
Default
The default is None.
Command Mode
Privileged EXEC
Example
The following data is shown in a tabular format as the output for this command.
(Routing)#show qcn statistics interface 0/1 cp-index 1
Interfax Cp Index CNMs transmitted

FIP Snooping Commands
The Fibre Channel over Ethernet (FCoE) Initialization Protocol (FIP) is utilized in order to perform the
functions of FC_BB_E device discovery, initialization, and maintenance. The FIP uses a separate
EtherType from FCoE in order to enable the capacity to distinguish discovery, initialization, and
maintenance traffic from other types of FCoE traffic. With only one exception, FIP frames are of the
standard Ethernet size (that is, 1518 Byte 802.1q frame), while FCoE frames have a maximum size of
2240 bytes.
This document describes FIP snooping. FIP snooping is a frame inspection method that is used by FIP
Snooping Bridges in order to monitor FIP frames and to apply policies based upon the L2 header
information included in those frames, following the recommendations in Annex C of FC_BB_5 Rev 2.00.
This makes the following actions possible:
1. The auto-configuration of Ethernet ACLs according to information included in the Ethernet
headers of FIP frames.
2. The emulation of FC point-to-point links within the DCB Ethernet network.
3. The enhancement of FCoE security/robustness through the prevention of FCoE MAC spoofing.
In D-LINK OS, the FIP Snooping Bridge solution supports configuration-only of the perimeter port role and
the FCF-facing port roles and is intended only for use at the edge of the switched network.
The roles of FIP Snooping-enabled ports on the switch are categorized under one of the following types:
1. Perimeter or Edge port (that is, connected directly to ENode).
