Hello everyone,<br />
I have a question about monitoring switchports. I am working with Cisco 3560 switches. but, I would suspect this would apply to all Cisco Switches and routers.<br />
<br />
I have used various snmp monitoring tools. Currently I am using Cisco NetManager and Cisco Network Assistant. These tools display the interface utilization of a giving interface. However, it does it in percentages. So, my question is, how does it calculate that value?<br />
<br />
Specifically, I have a gigabit interface that is running at 100mbps (becuase it's connected to a 100mbps device) and the switch is telling me that the interface is at %10 utilization, is that %10 of 1Gbps or %10 of 100Mbps?<br />
<br />
Does the bandwidth command on the interface affect this calculation?<br />
<br />
Thanks!

How does a Cisco switch calculate interface utilization

Network Operations includes asset management, help-desk supervision, security and user policies, infrastructure administration and anything else that affects the operation of your network. Discussions will include those of best practices in platforms, configurations, performance, security and accounting.

Network Operations

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

Networking Hardware-Other

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
