Hi, all
I am relatively new to this field. We have full T1
but the internet speed is very slow.
Sometimes it's even slower than dial-up speed when
downloading files.
E1 E0 E0 s0
Switch --- PIX ------Cisco 2600 Router------Internet
(E1 and E0 are Ethernet Interface and S0 is serial
interface) (please see the following status on s0)
Serial0/0 is up, line protocol is up
Hardware is QUICC Serial
Internet address is X.X.X.X/30
MTU 1500 bytes, BW 2048 Kbit, DLY 20000 usec,
reliability 255/255, txload 26/255, rxload
188/255
Encapsulation HDLC, loopback not set
Keepalive set (10 sec)
Last input 00:00:02, output 00:00:00, output hang
never
Last clearing of "show interface" counters never
Input queue: 0/75/9199/0 (size/max/drops/flushes);
Total output drops: 3307
Queueing strategy: weighted fair
Output queue: 0/1000/64/3307 (size/max
total/threshold/drops)

0 carrier transitions
DCD=up DSR=up DTR=up RTS=up CTS=up
I checked the S0 interface status on the internet
router. What info does the above indicate?
What does input and output packets mean in case
internal users download files from internet?
I really do not know how to find out where all traffic
are from? I bet there are lots of downloads
from internet. Where should I start?
BTW, we have one block class C public address. But
the PIX only use 30 for NAT and one
global pool address:
global (outside) 1 x.x1.x2.201-x.x1.x2.230
global (outside) 1 x.x1.x2.200
Could this cause the slowness on internet speed also?
Thanks in advance,
Jane
