Support for this command was introduced on the Cisco 7600 series routers.

Usage Guidelines
The show cable-diagnostics prbs command is supported on the 1-port 10GBASE-E serial 10-Gigabit Ethernet module (WS-X6502-10GE) only.
You can view the PRBS error counters only while the PRBS test is in progress. If the PRBS test has stopped running, N/A is displayed in the Error Counter field.
The PRBS error counter measures the reliability of the cable. The error counter range is 0 to 255. A value of 0 signifies a perfect link connection. A value of 255 signifies that the port is faulty or not connected or that there is no communication through the link. If the counter does not remain at zero for a predetermined length of time, the link is faulty. For example, for a baud error rate (BER) of 10^-12, the counter should remain at zero for 100 seconds.
Each time you access the PRBS counter by entering the show cable-diagnostics prbs command, the PRBS error counter value is reset to 0, and the counter begins to accumulate errors again.
Note
The PRBS counter is a "read and clear" register. The first reading in a sequence is usually unreliable and serves primarily to purge the counter; successive readings are accurate.
You must start the PRBS test on both ends of the cable and then read the error counter. If you start one end and read the error counter, a nonzero value counter is displayed, and a false alarm is generated.
Table 2-22 describes the fields in the show cable-diagnostics prbs command output.

|
Usage Guidelines
The number of valid values for channel-group depends on the software release. For releases prior to Release 12.1(3a)E3, valid values are from 1 to 256; for Releases 12.1(3a)E3, 12.1(3a)E4, and 12.1(4)E1, valid values are from 1 to 64. Release 12.1(5c)EX and later support a maximum of 64 values ranging from 1 to 256. Release 12.1(13)E and later support a maximum of 64 values ranging from 1 to 282; values 257 to 282 are supported on the CSM and FWSM.
If you do not specify a channel-group, all channel groups are displayed.
In the output, the Passive port list field is displayed for Layer 3 port channels only. This field means that the physical interface, which is still not up, is configured to be in the channel group (and indirectly is in the only port channel in the channel group).
In the show etherchannel protocol output if the interface is configured as part of the channel in mode ON, the command displays Protocol: - (Mode ON).
In the output of the show etherchannel summary command, the following guidelines apply:
•
In the column that displays the protocol used for the channel, if the channel mode is ON, a hyphen (-) is displayed.
•
For LACP, multiple aggregators are supported; for example, if two different bundles are created, Po1 indicates the Primary aggregator, and Po1A and Po1B indicate the secondary aggregators.
Examples
This example shows how to display port-channel information for a specific group:
Router> show etherchannel 12 port-channel

12.1(8a)E3
|
Support for this command was introduced on the Supervisor Engine 2.
|
12.1(11b)E
|
This command was changed to include switching mode information.
|
Usage Guidelines
The show fabric utilization command is supported on switches configured with a Supervisor Engine 2 only.
To display all related crossbar fabric information, enter the show fabric command without keywords.
If you specify slot, the information is displayed for the specified slot. If you specify all, the information for all slots using the crossbar fabric is displayed. If you do not specify slot or all, the display is the same as if you entered all.
A fabric channel is each connection between a module and the crossbar fabric module. Each module can have zero, one, or two fabric channels. The more fabric channels a module has, the more overall bandwidth is available to the module.
The following errors are associated with crossbar fabrics:
•
Synchronization errors—General errors are the most common types of errors.
•
Heartbeat errors—The supervisor engine sends out periodic heartbeat packets to each of the modules using the crossbar fabric as well as the crossbar fabric module itself. If any of these modules or the crossbar fabric fail to detect heartbeat packets for a period of time, this error is reported.
•
CRC errors—All packets crossing the crossbar fabric are CRC protected. If any of the ASICs between a module and the crossbar fabric module detect a CRC error, this error is reported.
The three types of fabric switching modes are as follows:
•
Bus—Packets travel across the traditional backplane shared by all modules to be switched by the supervisor engine. Modules without the crossbar fabric connectors are restricted to this mode. The 48-port 10/100TX RJ-45 module is an example of this module type.
•
Crossbar—Packets with headers only travel across the traditional backplane to be switched by the supervisor engine, and then these packets travel across the crossbar fabric. The 16-port Gigabit Ethernet GBIC switching module is an example of this module type.
•
dCEF—Packets are switched by the module itself and these packets travel across the crossbar fabric. The 16-port Gigabit Ethernet GBIC switching module and the 16-port Gigabit Ethernet module are examples of this module type. The 16-port Gigabit Ethernet GBIC switching module can be in any of these three modes, but the 16-port Gigabit Ethernet module can only be in dCEF mode.
Threshold information is shown only when you enter the no fabric switching-mode allow truncated command.
Examples
This example shows how to display the module switching mode:
Router> show fabric switching-mode
Fabric module is required for system to operate
Modules are allowed to operate in bus mode
Truncated mode is not allowed unless threshold is met
Threshold for truncated mode operation is 2 SFM-capable cards
Module Slot Switching Mode
This example shows the display if you previously entered the fabric switching-mode allow truncated command:
Router> show fabric switching-mode allow truncated
Fabric module is required for system to operate
Modules are allowed to operate in bus mode
Truncated mode is allowed

Usage Guidelines
If you can configure a VACL on the port before you configure CBAC, the status displayed is INACTIVE; otherwise, it is ACTIVE. If PFC resources are exhausted, the command displays BRIDGE followed by the number of failed currently active NetFlow requests that have been sent to the MSFC2 for processing.
The show fm insp command output includes this information:
•
interface:—Interface on which the IP inspect feature is enabled.
•
(direction)—Direction in which the IP inspect feature is enabled (IN or OUT).
•
acl name:—Name used to identify packets being inspected.
•
status:—(ACTIVE or INACTIVE) tells you if HW-assist is provided for this interface+direction (ACTIVE=hardware assisted or INACTIVE).
The detail option also displays the ACEs that are part of the ACL used for IP inspect on the given interface direction.

|
Usage Guidelines
The interface-number argument designates the module and port number. Valid values for interface-number depend on the specified interface type and the chassis and module used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module installed in a 13-slot chassis, valid values for the module number are from 2 to 13 and valid values for the port number are from 1 to 48.
The number of valid values for port-channel number depends on the software release. For releases prior to Release 12.1(3a)E3, valid values are from 1 to 256; for Releases 12.1(3a)E3, 12.1(3a)E4, and 12.1(4)E1, valid values are from 1 to 64. Release 12.1(5c)EX and later support a maximum of 64 values ranging from 1 to 256. Release 12.1(13)E and later support a maximum of 64 values ranging from 1 to 282; values 257 to 282 are supported on the CSM and FWSM.
If your system is configured with a Supervisor Engine 1, valid values for vlan-id are from 1 to 1005. If your system is configured with a Supervisor Engine 2, valid values for vlan-id are from 1 to 4094. Extended-range VLANs are not supported on systems configured with a Supervisor Engine 1.

Usage Guidelines
The interface-number argument designates the module and port number. Valid values for interface-number depend on the specified interface type and the chassis and module used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module installed in a 13-slot chassis, valid values for the module number are from 2 to 13 and valid values for the port number are from 1 to 48.
If your system is configured with a Supervisor Engine 1, valid values for vlan-id are from 1 to 1005. If your system is configured with a Supervisor Engine 2, valid values for vlan-id are from 1 to 4094. Extended-range VLANs are not supported on systems configured with a Supervisor Engine 1.
Statistics are collected on a per-VLAN basis for Layer 2-switched packets and Layer 3-switched packets. Statistics are available for both unicast and multicast. The Layer 3-switched packet counts are available for both ingress and egress directions. The per-VLAN statistics are updated every 5 seconds.
In some cases, you might see a difference in the duplex mode displayed between the show interfaces command and the show running-config commands. In this case, the duplex mode displayed in the show interfaces command is the actual duplex mode the interface is running. The show interfaces command shows the operating mode for an interface, while the show running-config command shows the configured mode for an interface.
If you do not enter any keywords, all counters for all modules are displayed.

12.1(12c)E
|
This command was changed to support the multicast and unicast keywords.
|
12.1(13)E
|
This command was changed to support the etherchannel keywords.
|
Usage Guidelines
The show interfaces [interface] counters command displays the number of all of the packets arriving and includes the number of packets that may be dropped by the interface due to the storm-control settings.
If you do not enter any keywords, all counters for all modules are displayed.
When you enter the interface, these formats can be used:
•
card-type {slot}/{first-port} - {last-port}
•
card-type {slot}/{first-port} - {last-port}
You can define a single port range per command entry. If you specify a range of ports, the range must consist of the same slot and port type.
When you define a range, you must enter a white space between the first port and the hyphen (-) as follows:
show interfaces gigabitethernet7/1 -7 counters
The module number keyword and argument designate the module number and limits the display to interfaces on the module. Valid values depend on the chassis used. For example, if you have a 13-slot chassis, valid values for the module number are from 2 to 13.
Valid values for card-type are as follows:
•
ethernet
•
fastethernet
•
gigabitethernet
•
tengigabitethernet
•
port-channel interface-number
The module number keyword and argument designate the module and port number. Valid values for number depend on the chassis and module used. For example, if you have a 48-port 10/100BASE-T Ethernet module installed in a 13-slot chassis, valid values for the module number are from 2 to 13 and valid values for the port number are from 1 to 48.
The outputs of the show interfaces {counters {broadcast | multicast | unicast} commands display the total discard count for all three suppression modes, not the discard count for each suppression mode.
If you enter the show interfaces [interface_id] counters command without entering the broadcast, multicast, or unicast option, the discard count is not displayed.
When you enter the show interface interface counters etherchannel command, follow these guidelines:
•
If interface specifies a physical port, the command displays this message, "Etherchnl not enabled on this interface."
•
If interface is omitted, the command displays the counters for all port channels (in the system) and for their associated physical ports.
Examples
This example shows how to display error counters for a specific module:
Router> show interfaces counters errors module 1
