bandwidth rate

The following is the Gateway Router external interface counters::::

stEthernet0/1 is up, line protocol is up

Hardware is Gt96k FE, address is 0013.c3c2.6c8b (bia 0013.c3c2.6c8b)


Internet address is

MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,

reliability 255/255, txload 1/255, rxload 5/255

Encapsulation ARPA, loopback not set

Keepalive set (10 sec)

Full-duplex, 100Mb/s, 100BaseTX/FX

ARP type: ARPA, ARP Timeout 04:00:00

Last input 00:00:07, output 00:00:00, output hang never

Last clearing of "show interface" counters never

Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0

Queueing strategy: weighted fair

Output queue: 0/1000/1024/0 (size/max total/threshold/drops)

Conversations 0/2/256 (active/max active/max total)

Reserved Conversations 0/0 (allocated/max allocated)

Available Bandwidth 75000 kilobits/sec


30 second input rate 1984000 bits/sec, 308 packets/sec

30 second output rate 757000 bits/sec,

-------------------------------------- 271 packets/sec

7297947 packets input, 2758474231 bytes

Received 1108 broadcasts, 0 runts, 0 giants, 0 throttles

1 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored

0 watchdog

Please, do look at the input rate and output rate.

My company is having 2Mbps link intranet link , I haven't set any bandwidth on this interface:

My doubt is the total bandwith utlization on the link would be the sum of

out put rate and input rate... OR only output rate,and only input rate... I just completed my CCNA .. I am total confused with this.. I would be grateful ,, If any one can give a reliable answer for that....


Re: bandwidth rate

The "Bandwidth" statement does not affect the actual throughput, it is there for some routing protocols (like EIGRP and OSPF) to become part of the "best path" determination. Some monitoring and management software will also use that number to establish the 100% baseline.

You can edit that statement for each interface independently. Fast Ethernet will automatically default to 100,000 Kbit (like T1 will default to either 1544K or 1536K depending on the hardware).

The bandwidth provided by the ISP / carrier would be full duplex (usually), so that you are likely getting 2 Meg down as well as 2 meg up (at the same time ... "4 meg" in marketing-speak ;-} )

Re-post if you have any other questions ...

Good Luck
