How to connect X440G2-24t-G4

[Alex_audv]

We have a problem whit two switches X440G2-24t-G4, after to connect by port 24 the connection is lost.

It is possible to connect them two switch X440G2-24t-G4 in cascade mode by any ethernet port?

Thanks for yous help

I'll give it a try tomorrow in my lab, maybe I'll get a hint.
Did you try the software-update?

Regarding duplicate MAC-Adresses you could try the command from https://community.extremenetworks.com/extremeswitching-exos-223284/how-can-i-detect-a-new-entry-in-the-fdb-table-7823038

code:

configure log filter defaultFilter add events FDB.MACTracking.MACAdd
configure fdb mac-tracking add ports all

and take a look into the logs if there is a mac-adress flapping.

For the unlikely event of your cable being damaged you could try the command

code:

run script cablediag.py -p 24

Hi Rahman

If I connect the pc directly to firewall is work perfectly.
If connect only one switch witht the firewall, the network is work perfectly.
The problen is begin when two swiches are conected bouth switches with rj45-ports (24), W e can access to internet, but we can't access to other to devices in the network.

Thanks.

Hi Alex,

You have only one vlan (default/vlan 1) so it does not matter if you tag it or not between switches. Your config looks ok but there are a lot of dark point about your setup. As I asked before, if you disconnect the switches completely from your firewall and connect one of the PC to flrewalls port, does it work? Does it get correct up setting from DHCP? What does PC's use as their gateway?

Regards,
Rahman

Hi CFaber

I'll check all MAC addres, but I think is dificult to see duplicated.

Thanks.

Hi CFaber

We conected bouth switches with rj45-ports (24), after your recomendation:
"Using an untagged (=> Access port!) VLAN between two switches shouldn't be used in favor to using tagged vlans (=> trunk).
If you still want to use it you should configure:
code:
configure vlan Default delete ports 24
configure vlan Default add ports 24 tagged"

The network behavior is unstable.

I attached logs,
