Latency

[ricfsantos]

Hi all,

I'm doing my first lab using Nokia VSRs, and I'm seeing that the latency between directly connected interfaces looks too high. I'm using the EVE-PRO 2.0.5 and Nokia VSR 16.0.R6

Here is an example:

A:PE1-R6# show router interface

Interfaces : 4

Ping to P1-R2 :
A:PE1-R6# ping 10.1.100.26
PING 10.1.100.26 56 data bytes
64 bytes from 10.1.100.26: icmp_seq=1 ttl=64 time=9.33ms.

And here is a ping from my test PC to a GW with 4 hops of distance :

VPCS> ping 10.5.10.1

84 bytes from 10.5.10.1 icmp_seq=1 ttl=64 time=30.466 ms
84 bytes from 10.5.10.1 icmp_seq=2 ttl=64 time=52.372 ms
84 bytes from 10.5.10.1 icmp_seq=3 ttl=64 time=25.633 ms
84 bytes from 10.5.10.1 icmp_seq=4 ttl=64 time=42.401 ms
84 bytes from 10.5.10.1 icmp_seq=5 ttl=64 time=22.774 ms


Is this the expected behavior?

My EVE-VM is installed in an ESXi 6.7 Server.

You can change your network driver adaptor at the template, you must test with another and it will hopefully work better

Thank you for this suggestion... I tried all types of interfaces but the result remains the same.
