Hi,
I've experience a very strange behaviour with Cat4500E-SUP6L switches.
The switches are making only L2 forwarding.
When port-security is activated some of the clients are stop receiving DHCP addresses.
The interfaces where the clients connected to not reaching the maximum MAC address limit.
Static IP configuration is working, after deactivating port-security the problem resolves.
Removing DHCP snooping which is activated as well not resolving the issue.
Most of the issued clients are Cisco IP Phone, but not only.
Anyone has an idea ?
Thanks,
