Cat Express 500 Slow Admin and keeps crashing

[gilbera]

Hi

I have a customer with 2x WS-CE500-24PC and 2x WS-CE500-24TT

They are brand new and most ports are set to IP Phone smartports with 2 as wireless access ports and 1 router port with an 1841 in it. They are all uplinked together.

When first rebooted http admin access is ok but after a couple of minutes it becomes un-usable and then eventually the switch reboots (does this 2 times a day).

i have 1x WS-CE500-24LC and this is fine never misses a beat, its also linked into the same network.

here is where it gets crazy, if i set all the ports to other its fine, but i cannot use any of the phones because it does not put them in the voice VLAN.

Any ideas it driving me and my customer mad.

Try to disable the arp inspection feature in the CE500's CLI.

This feature can sometimes introduce some disconnectivity on this particular switch.

Enter the following line in your browser:

http://10.0.0.1/exec/cli

ip arp inspection vlan 1-1024

ip arp inspection vlan 1-1024 logging acl-match none

ip arp inspection vlan 1-1024 logging dhcp-bindings none

If your switch uses a different ip address than please use that address. After you applied this, it will take about 15 till 20 minutes to decrease the cpu utlization.
