Hi
With our lab, on N3 with 1 DFE Platinium 48 ports :
Netsight 4.2 : with redirection – between 5 and 10 s
Without redirection – 15s
Netsight 4.3 : with redirection – between 30 and 45 s
Without redirection – 15 s
We are testing the 4.3 on a production network with 52 switchs (1 N3, 1 N1, 2
SSA, 48 G3) and with compass, it take between 3 and 5 minutes to retrieve an ip
adress with the redirection and 1 minute without redirection.
The 4.2 take 1 minute with and without redirection.

Hi,
The netsight latency with snmp redirection appeared with netsight 4.3.
All comparative tests do not show any problem with earlier versions, this is
why some people are complaining about this new behaviour.
I have a case about this situation if you want to a look into this problem.
Cordialement,
Sylvain CONTI.

Sylvain,
Did you had the problem before as well, I mean for example with versions 3.3,
4.0, 4.1, 4.2? Just asking because I've seen your name for many years I think
on here in the newsgroup and I think you also have experience with a lot of
netsight versions from the past.
Or did the problems just started now with 4.3, like at Geoffrey?
I have just very few customers which are using snmp redirection, but all with
high latency WAN/VPN networks, where I thought it is normal.
Thanks in advance.
Kind regards,
Markus

Hi,
In my lab.
Server (virtual appliance) and remote desktop on the same vlan/ip
network.
A 24ports switch same vlan/ip network, flexview interface summary :
- with redirection : 30secondes
- without redirection : 2secondes
Can you explain the difference with your formula ?
At customer site with 30 chassis dfe with 5-7 boards it is unusable.
Policy Manager is affected ...

Hello,
how long is the round-trip time between you or the netsight server and
the device?
There are many snmp requests going on if you try to retrieve port
information from a switch for many ports.
Let's say 480 snmp requests for 10 stats about 48 ports.
480x 1ms = 480 ms to get the information from switches within a LAN.
If your client is remote with a round-trip time of 120ms to netsight or
netsight to device, that makes
480x 120ms = 57,6 seconds until information is retrieved.
This is not a problem or issue of netsight.
Hope this helps.
Kind regards,
Markus

Hello,
We are testing the latest Netsight (4.3.0.94). When we enable the SNMP
redirection, the display for ports or Vlan information of a switch is very
long. When we disable the SNMP redirection, all is coming as usual.
Has everyone seen the same problem ?
