Bandwidth?

[rwhall51]

Is there a command to see what the bandwidth on a particular interface is?

 

[Saeed42]

Show interface (and the interface i.e e0)

Bolew is example of show int d1 and as you can see it shows the BW

sho int d1
Dialer1 is up (spoofing), line protocol is up (spoofing)
Hardware is Unknown
Interface is unnumbered. Using address of Ethernet0 (194.126.71.41)
MTU 1500 bytes, BW 56 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation PPP, loopback not set
Keepalive set (10 sec)
DTR is pulsed for 1 seconds on reset
Last input never, output never, 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: fifo
Output queue :0/40 (size/max)
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
0 packets input, 0 bytes
0 packets output, 0 byt
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Don't be content with being average. Average is as close to the bottom as it is to the top

I guess I am looking for the amount of bandwidth that is been used on a port. I know what the total bandwidth is. Thanks for the reply. Any help with this?

Look at the previous post. It shows five minute input and output rate. If you need something a little more functional, you can look into Multi Router Traffic Grapher (MRTG). It's free but takes some effort to get it configured.

Hi,
You can also reference the txload and rxload, they are a little confusing as Cisco like to talk in terms of x/255 rather than in a percentage. MRTG is an excellent tools for looking at general Bandwidth usage. Ther are other methods too, like Cisco's NetFlow, but you need an expensive server to do that on - but it does give you real time stats rather than the (default but configurable) 5 minute counton MRTG.
