CPU Load on a 2600 |
|
|
Hi everyone,
I'm pretty new cisco gear so I'm not too sure about it. But anywho. I
have a cisco 2651 running my 1.5mbit (256kbit up) adsl internet
connection and I am interested in the cpu load.
The 72 hour graph seems to be pretty high, it seems to spike to 100%
every few hours.
I hope this comes out (sorry not used google groups before either):

CPU% per hour (last 72 hours)
Now it shouldn't be doing too much. I has a PPPoE connection to an
external modem, an IPv6 tunnel and a basic PPTP server which doesn't
get used much. It nats traffic to the internal computers and does some
basic port forwarding.
Does the CPU load look okay for such a connection? Let me know if I
need to post config etc! |

The first thing is; what does this graph actually tell you.
I suggest that you use snmp (getif is free) to chart the
CPU properly.
Alternatively use "sh proc cpu" when it is high
and post that.
A 2651 is a pretty decent router for an ADSL,
however there are a number of possible issues.
Tunneling is pretty costly for the router. If it is having to
fragment packets to get them into the tunnel then that
is costlier still.
As usual, have you got fast switching on? "ip route-cache".

You are right, the CPU load does seem to be high given the interfaces
and speeds you are using. As there is no config to base this on a
simple guess would say you are probably process switching all traffic
and not using fast switching or cef switching. If the statement -
ip cef
is NOT present in your config, try adding it in global config mode and
see if it has any affect. if no change then a post of your config
would help heaps to understandng what your Router is doing. I am also
not sure what IPV6 might do to things either, but adding CEF (if it is
not present) is probably a good start.
Cheers.................pk.

CEF is enabled which is good, howeve,r quite a few packets are still
being process-switched as seen in the output of sh int stats
Most of the CPU time is being consumed by process "Key Proc" (I assume
this is encyption procesing) and "process "IP input" which is the
process-switching of IP packet (i.e non-CEF switched):
PID Runtime(ms) % CPU Invoked Process
109 687348 36.3% 3434 Key Proc
43 517351 27.3% 345267 IP Input
6 315647 16.6% 59122 Check heaps
35 297561 15.7% 9717 Per-minute Jobs
I would suggest you try a different IOS image to see if you get a
better result.

All of the encryption is done in software and a can be very CPU intensive.
If you are able to get some SNMP monitoring I would bet that CPU utilization
mirrors bandwidth utilization. If this is the case, and encryption AIM would
bring down the CPU utilization (it would offload the encryption from the
CPU). 1.5 Mbs, 256 kbs is a lot of encrypted data to push without an
encryption AIM anyway.

Thanks for the reply.
The only time encryption should happen is when I'm connected to the
PPTP VPN, which would only be a few hours during the day.
The load seems to happen throughout the day and night. |

This is a very neat analysis which is a new method to me.
It is however in this case I believe not of much assistance.
Total runtime above it 700 + 500 + 300 + 300 secs
1800 secs or half an hour.
Router has been up for:
6 days, 17 hours, 45 minutes
, say 200 hours.
so stats represent only 1/400 of the routers uptime.
As mentioned already, the crude histograms
from sh proc cup hist tell you basically nothing at all.
If that is all you have to go on, I wouldn't worry.
If you are still concerned get some decent numbers
with say snmp and getif and post them here.
Sample the CPU every second or two
and post the results.
I will however take a stab myself:-
It looks as if the peaks may be due to some periodic
crypto operation such and perhaps key exchanges.
Good luck. |
