Comware

Hello,

Last day i had a case that, i couldn't communicate 2 switches with eachother.

The topology is the most simple u may think of, such as;

Procurves running om the topology, on default configuration (Vlan1), and i tried to connect a Comware switch to one of them. Comware (51xx) is also running on default configuration. 

On both switchs vlan 1 (comware int vlan 1) have IP on the same subnet,  all ports on default (means " access vlan 1 " as you know ). But can not ping each other.

Also tried  " vlan X " on both switches and trunk on uplink ports. But, couldn't ping eighter.

What could I miss on this situation? Was there any trick on comware?

Kind Regards..

From where are you trying to ping? from the switch or from your pc ?

If it is from your pc, try to disable your firewall.

Hello,

I am trying it from switch to switch, i can ping it from laptop. The problem is, i just can not make uplink work.

Hi,

Are the switches directly connected?

I.e on the comware switch

Hi,

What address are you pinging?

The procurve 2530, says it has: "Management address : 10.3.4.124", but you wrote it as if you configured 10.3.1.20.

You can do a "display interface brief | incl ^Vlan" to see what address it has assigned to interface vlan1

Regards

Hi,

Thank you for your attention. Don't mind ip addresses, the outputs has taken in different times, its the reason that ip address shown diffrent, i was trying something. Consider as there is no ip address configuration problem.

Just curious, if is there any little trick or something for communicate between comware and procurve switches.

Regards.

Hello

The fact you can ping everything from your client, means that your uplink works fine. 

Can you try to do following commands on your comware switch, and check again if you can ping or not.

 ip ttl-expires enable
 ip unreachables enable

I think one of the switches is just blocking pings.

Hi,

Is the problem asymmetric? (I mean can you ping from the Aruba, but not from the Comware, or vice versa)

Anyways, you can try to explicitly allowing ping on the Aruba device.

# ip icmp echo broadcast-request

 Regards
