2510-24 erratic ping response

[PhilUK]

Hi,

I have just received delivery of two new HP 2510-24 switches and given them an IP address and enabled Spanning Tree.

When I ping the switches I'm getting the following responses.

I have changed all network cables and upgraded the firmware to Q.11.57.  There are no other devices connected. All other switches are ping at 1 ms or <1ms.  These are 3400cl's and 2810's and 2650's.

Does anyone have any idea why I'm receiving these ping responses from the 2510.

Thanks

Hi

There's nothing strange, or alarming. Here's a document concerning erratic ping times:

Thanks for the quick reply.

That said, there is usually not a huge variation in ping times in a non-congested network.  Here's a graph of ping times from my management server to my 3400cl on the same VLAN:
