Baseline 2948 IP address not responding
My problem is this, my 2948 switch has been working for the last 6 months, I can access web interface and ping the management IP. Now suddenly I am not able to ping or access the web interface.I connected via console cable changed the IP to auto, it immediately got a new IP from DHCP but I am still unable to ping/access it. I then changed it back to static and still no change.
The switch has VLAN's configured and is working in that aspect. Only thing is I cannot manage it at all.
Any assistance will be greatly appreciated.
Kind Regards,
Jvrs

Re: Baseline 2948 IP address not responding
Thanks for the reply. I have tested it in both scenarios, from the same IP range as the management IP and from the VLAN IP range. That has not made a difference.
Kind Regards,

Re: Baseline 2948 IP address not responding
In addition, to losing the ip addess this switch becomes increasingly unstable over time. After a period of several months, I have to take the switch offline, restore to factory default and rebuild. It works well for a few months and then we start over.
At this point, I have taken the switch out of production and replaced it with the 2 older 2824 models. These have performed very well for the last 3 or 4 years.
I am Currently evaluating Cisco 2960 to replace the 2948

Re: Baseline 2948 IP address not responding
I've seen similar loss of IP address on some of these switches. Connecting to the console and running summary shows that the configuration isn't lost, just the functionality. Resetting the IP address via the command line fixes - but sometimes only temporarily! I've also experienced the IP connectivity coming back.
We've had other 2948s running for years and not show the problem.
Don't understand. Is it related to the ARP table getting full - I notice it is limited to the very small value of 256?
I wish there was a fix, as we have dozens of the things! They seemed such good value for money at the time ...
