Cisco Interface Saturation - Top Talker Script Interpretation
Hello Community,
We've been experiencing high utilisation on our interface, to the point where the rx is full saturated, see below:
ukxxxx-rm01-xx#show int atM 0/1/0
ATM0/1/0 is up, line protocol is up
Hardware is MPC ATMSAR, address is 6073.5cd8.95a6 (bia 6073.5cd8.95a6)
Description: Internet Connection
MTU 1600 bytes, sub MTU 1600, BW 448 Kbit/sec, DLY 820 usec,
reliability 255/255, txload 137/255, rxload 255/255
I decided to apply the attached script to determine what might be causing the saturation. I have also attached an explanation of how the script works.
Can someone please help me interpet the output?
The culprit is the source ip 194.75.x.x to 80.229.x.x with prot ESP and AvgBits/s 1.19M and AVGpkt/s 175.
I don't know how to interpret the results...
Any explanation would greatly appreciated.
Cheers
Carlton

ESP is typically used for VPN tunnels. Do you have a site to site VPN tunnel?

Routers
A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
