100VG-AnyLAN Port Adapter

Description

The 100VG-AnyLAN port adapter (PA-100VG) is available on Cisco 7200 series routers, Cisco 7500 series routers, and on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI).

The PA-100VG provides a single interface compatible with and specified by IEEE 802.12 to support 100 Mbps over Category 3 or Category 5 unshielded twisted-pair (UTP) cable with RJ-45 terminators. The PA-100VG supports 802.3 Ethernet packets and can be monitored with the IEEE 802.12 Interface MIB.

Platforms

This feature is supported on these platforms:

•Cisco 7200 series

•Cisco 7500 series

•Cisco 7000 series with the RSP7000 and RSP7000CI

Configuration Task

To configure the PA-100VG port adapter, perform the following tasks beginning in global configuration mode:

Task

Command

Step 1 Specify a 100VG-AnyLAN interface and enter interface configuration.

interface vg-anylan slot/port-adapter/port (Cisco 7000 and Cisco 7500)

interface vg-anylan slot/port (Cisco 7200)

Step 2 Specify the IP address and subnet mask to the interface.

ip address ip-address mask¹

Step 3 Configure the frame type. Currently, only Ethernet frames are supported. The frame type defaults to Ethernet.

frame-type ethernet

¹This command is documented in the "IP Commands" chapter of the Network Protocols Command Reference, Part 1.

Note The port number for the 100VG-AnyLAN port adapter is always 0.

Configuring the PA-100VG interface is similar to configuring an Ethernet or Fast Ethernet interface. For information on other configuration tasks for the PA-100VG port adapter, refer to the "Configure an Ethernet or Fast Ethernet Interface" section in the "Configuring Interfaces" chapter of the Configuration Fundamentals Configuration Guide.

For information on other commands that can be used by the PA-100VG interface, refer to the Cisco IOS Release 11.2 configuration guides.

To display information about the 100VG-AnyLAN port adapter, use the show interfaces vg-anylan EXEC command.

Configuration Examples

Following is an example of a basic configuration for the PA-VG100 port adapter interface in slot 1 on a Cisco 7500 series router. In this example, IP routing is enabled on the router, so an IP address and subnet mask are assigned to the interface.
router# configure terminal
router(config)# interface vg-anylan 1/0/0 
router(config-if)# ip address 1.1.1.10 255.255.255.0 
router(config-if)# no shutdown 
router(config-if)# exit
router(config)# exit
router#

Table 31 Show Interfaces VG-AnyLAN Field Descriptions

Field

Description

VG-AnyLAN3/0/0 is up, line protocol is up

Indicates if the interface hardware is currently active and can transmit and receive or if it has been taken down by an administrator.

Hardware is cyBus VG-AnyLAN

Hardware type.

Frame type is 803.2

Currently the frame type supported is 803.2.

Internet address

Internet address and subnet mask.

MTU

Maximum transmission unit of the interface.

BW

Bandwidth of the interface in kilobits per second.

DLY

Delay of the interface in microseconds.

rely

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

load

Load on the interface as a fraction of 255 (255/255 is completely saturated), calculated as an exponential average over 5 minutes. The calculation uses the value from the bandwidth interface configuration command.

Encapsulation

Encapsulation method assigned to the interface.

loopback

Indicates if loopbacks are set.

keepalive

Indicates if keepalives are set.

ARA type

ARP type on the interface.

Last input

Number of hours, minutes, and seconds since the last packet was successfully received by an interface. Useful for knowing when a dead interface failed.

output

Number of hours, minutes, and seconds since the last packet was successfully transmitted by an interface.

output hang

Number of hours, minutes, and seconds (or never) since the interface was last reset because of a transmission that took too long. When the number of hours in any of the "last" fields exceeds 24 hours, the number of days and hours is printed. If that field overflows, asterisks are printed.

last clearing

Time at which the counters that measure cumulative statistics (such as number of bytes transmitted and received) shown in this report were last reset to zero. Variables that might affect routing (for example, load and reliability) are not cleared when the counters are cleared.

*** indicates the elapsed time is too large to be displayed.

0:00:00 indicates the counters were cleared more than 231ms (and less then 232ms) ago.

Queueing strategy

First-in, first-out queuing strategy (other queueing strategies you might see are priority-list, custom-list, and weighted fair).

Output queue, drops
input queue, drops

Number of packets in output and input queues. Each number is followed by a slash, the maximum size of the queue, and the number of packets dropped because a queue was full.

5 minute input rate
5 minute output rate

Average number of bits and packets received or transmitted per second in the last 5 minutes.

packets input

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

bytes (input)

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

no buffer

Number of received packets discarded because there was no buffer space in the main system. Compare with ignored count. Broadcast storms on Ethernets and bursts of noise on serial lines are often responsible for no input buffer events.

broadcasts

Total number of broadcast or multicast packets received by the interface.

runts

Number of packets that are discarded because they are smaller than the medium's minimum packet size.

giants

Number of packets that are discarded because they exceed the medium's maximum packet size.

input errors

Total number of no buffer, runts, giants, CRCs, frame, overrun, ignored, and abort counts. Other input-related errors can also increment the count, so that this sum might not balance with the other counts.

CRC

Cyclic redundancy checksum generated by the originating LAN station or far-end device does not match the checksum calculated from the data received. On a LAN, this usually indicates noise or transmission problems on the LAN interface or the LAN bus itself. A high number of CRCs is usually the result of collisions or a station transmitting bad data. On a serial link, CRCs usually indicate noise, gain hits or other transmission problems on the data link.

frame

Number of packets received incorrectly having a CRC error and a noninteger number of octets. On a serial line, this is 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.

ignored

Number of received packets ignored by the interface because the interface hardware ran low on internal buffers. These buffers are different than the system buffers mentioned previously in the buffer description. Broadcast storms and bursts of noise can cause the ignored count to be incremented.

abort

Illegal sequence of one bits on the interface.

input packets with dribble condition detected

Dribble bit error indicates that a frame is slightly too long. This frame error counter is incremented just for informational purposes; the router accepts the frame.

packets output

Total number of messages transmitted by the system.

bytes (output)

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.

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, as some datagrams can have more than one error, and others can have errors that do not fall into any of the specifically tabulated categories.

collisions

Number of messages retransmitted due to an Ethernet collision. This is usually the result of an overextended LAN (Ethernet or transceiver cable too long, more than two repeaters between stations, or too many cascaded multiport transceivers). A packet that collides is counted only once in output packets.

interface resets

Number of times an interface has been completely reset. This can happen if packets queued for transmission were not sent within a certain interval. If the system notices that the carrier detect line of an interface is up, but the line protocol is down, it periodically resets the interface in an effort to restart it. Interface resets can also occur when an unrecoverable interface processor error occurred, or when an interface is looped back or shut down.

output buffer failures

Number of times that a packet was not output from the output hold queue because of a shortage of MEMD shared memory.

output buffers swapped out

Number of packets stored in main memory when the output queue is full; swapping buffers to main memory prevents packets from being dropped when output is congested. The number is high when traffic is bursty.

vg alignment error

Number of non-octets received.

vg balance error

Number of incorrect balanced symbols received.

vg invalid ipm error

Number of packets received with an invalid packet marker (IPM).

vg symbol error

Number of symbols received that were not correctly decoded.

vg skew error

Number of skews between four pairs of twisted-pair wire that exceeded the allowable skew.

vg frame delimit error

Number of start-of-frame errors or false-start errors received.

vg high priority packets

Number of high-priority packets received.

vg high priority octets

Number of high-priority octets received.
