Is it correct to calculate the load as I showed above?
I found also the following information on the interface from the CLI`csr1000v#sh interfaces gigabitEthernet1`:
csr1000v#show interfaces gigabitEthernet 1 GigabitEthernet1 is up, line protocol is up ... reliability 255/255, txload 3/255, rxload 1/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full Duplex, 1000Mbps, link type is auto, media type is Virtual output flow-control is unsupported, input flow-control is unsupported ... Queueing strategy: fifo Output queue: 0/40 (size/max) 30 second input rate 1000 bits/sec, 3 packets/sec 30 second output rate 4000 bits/sec, 1 packets/sec 1003836 packets input, 174201781 bytes, 0 no buffer Received 0 broadcasts (0 IP multicasts) ... 169446 packets output, 80281698 bytes, 0 underruns ....
There is this txload and rxload values, would be used somehow to measure the loads?
Re: What are metrics to measure the load in Cisco Routers
on the physical interface the txload/rxload refers to the speed of the interface
Full Duplex, 1000Mbps, link type is auto, media type is Virtual
For the GRE tunnel that is a logical interface, setting a bandwdith of 256 kbps as you have done does not mean that traffic over the tunnel will be limited up to that bandwidth limit. Effective traffic can be more then configured bandwidth.
However, being a logical interface there is no concept of current actual speed of the interface so yes txload/rxload should refer to the stated bandwidth, but all traffic near to 256 kbps or greater will give you a 255/255 txload measure. As this is just a conversion of a percentage where 255/255 means 100%.
Also notice that the calculation is actually an average made based on the 30 seconds load interval, it takes 4 time intervals for the average to reach the value of traffic with a constant speed.
With default 5 minutes load interval it takes 20 minutes for the average to reach the offered rate.
