Network droping packets
Posted on 2016-08-02
My network was working fine, for instance pings to servers were not drop and under 1ms.
All of the sudden in a ping to a server in my LAN I'm seeing huge delays, for instance "time=152ms"
I have 3 main VLANs namely
VLAN 1: For all my users
VLAN 20: For VoIP
VLAN 50: For some video recording security cameras and server
VLAN 88: For all my servers. (The servers are in a VMware Cluster).
These are my tests using a host in VLAN 1: (10.10.70.53)
Reply from 10.10.70.4: bytes=32 time<1ms TTL=64
As a matter of fact any IP in this VLAN is under 1ms.
Reply from 10.10.88.10: bytes=32 time=149ms TTL=63
Reply from 10.10.50.10: bytes=32 time=150ms TTL=127
I just tested and the ping times are back to <1ms for everything.
As far as I can tell this lasted for about 1 hour.
It looks as if there is a program in a computer somewhere generating absurd quantities of traffic in the network.
If I'm right How can I identify the culprit?
One weird thing though is why there was no delay while pinging inside the VLAN 1?
Thanking you in advance,
