Table 1 describes the significant fields shown in the display.

 

Table 1 show interface loopback Field Description

Field
Description

Loopback is ...

Whether the interface hardware is currently active (whether carrier detect is present), is currently inactive (down), or has been taken down by an administrator (administratively down).

Hardware

Hardware is Loopback.

MTU

Maximum transmission unit (MTU) of the interface.

BW

Bandwidth (BW) of the interface in kilobits per second.

DLY

Delay (DLY) of the interface in microseconds.

reliability

Reliability of the interface as a fraction of 255 (255/255 is 100 percent reliability), calculated as an exponential average over 5 minutes.

txload

Load on the interface for transmitting packets as a fraction of 255 (255/255 is completely saturated), calculated as an exponential average over 5 minutes.

rxload

Load on the interface for receiving packets as a fraction of 255 (255/255 is completely saturated), calculated as an exponential average over 5 minutes.

Encapsulation

Encapsulation method assigned to an interface.

LOOPBACK

Whether loopback is set.

packets input

Total number of error-free packets received by the system.

bytes

Total number of bytes, including data and MAC encapsulation, in the error-free packets received by the system.

multicast frames

Total number of multicast frames enabled on the interface.

compressed

Total number of multicast frames compressed on the interface.

input errors

Sum of all errors that prevented the receipt of datagrams on the interface being examined. This number might not balance with the sum of the enumerated output errors, because some datagrams might have more than one error and others might have errors that do not fall into any of the specifically tabulated categories.

frame

Number of packets received incorrectly that have a CRC error and a noninteger number of octets. On a serial line, the problem usually the result of noise or other transmission problems.

overrun

Number of times the serial receiver hardware was unable to hand received data to a hardware buffer because the input rate exceeded the receiver’s ability to handle the data.

fifo

Number of First In, First Out (FIFO) errors in the receive direction.

packets output

Total number of messages transmitted by the system.

bytes

Total number of bytes, including data and MAC encapsulation, transmitted by the system.

underruns

Number of times that the far-end transmitter has been running faster than the near-end router’s receiver can handle. This condition might never happen (be reported) on some interfaces.

output errors

Sum of all errors that prevented the final transmission of datagrams out of the interface being examined. Note that this might not balance with the sum of the enumerated output errors, because some datagrams might have more than one error, and others might have errors that do not fall into any of the specifically tabulated categories.

collisions

Loopback interface does not have collisions.

fifo

Number of First In, First Out (FIFO) errors in the transmit direction.

This example shows how to display WCCP global statistics:

switch# show ip wccp 90

 

Global WCCP information:
Router information:
Router Identifier: 1.104.217.34
Protocol Version: 2.0
 
Service Identifier: 61
Number of Service Group Clients: 1
Number of Service Group Routers: 1
Service mode: Open
Service Access-list: -none-
Redirect Access-list: red1
Service Identifier: 62
Number of Service Group Clients: 1
Number of Service Group Routers: 1
Service mode: Open
Serivce Access-list: -none-
Redirect Access-list: red1
 

The following table entries describe the significant fields shown in the display:

 

Field
Description

Router information

List of routers detected by the current router.

Protocol version

Version of WCCP used by the router in the service group.

Service identifier

Service is detailed.

Number of service group clients

Number of clients visible to the router and other clients in the service group.

Number of service group routers

Number of routers in the service group.

Service mode:Closed

WCCP service mode. Options are open or closed.

Service access list

Named extended IP access list that defines the packets that will match the service.

Redirect access list

Name or number of the access list that determines which packets will be redirected.

This example shows how to display the other members of a service group:

switch# show ip wccp 10 view
 
WCCP Router Informed of:
10.168.88.10
10.168.88.20
 
WCCP Cache Engines Visible
10.168.88.11
10.168.88.12
 
WCCP Cache Engines Not Visible:
-none-
 

Note The maximum number of service groups that can be configured is 256.


If any cache engine is displayed under the WCCP Cache Engines Not Visible field, the router needs to be reconfigured to map the cache engine that is not visible to it.

The following table describes the significant fields shown in the display.
