4507R+E will let clients communicate, but if someone needs to renew their lease on DHCP, it will not renew the IP. All other clients in other areas/switches/subnets are using DHCP with no problem.
The configuration I've seen that appears "flaky" is...
I have some clients that are permanently remote. I want their laptop to log into ASA VPN using machine authentication without the user, base on a scheduled task that I will create.
Is this possible?
We just completed the packet capture on the bad switch and a known good switch.
On the bad switch we see a DHCP Discover go out and DHCP Ack come back. No Offer or Request.
We see all packets on the known good switch.
I have another switch with the same symptoms and it also shows the same abnormal etherchannel detail.
Ports in the group: -------------------Port: Te3/1------------
Port state = Up Mstr In-Bndl Channel group = 1 ...
I haven't had a chance to do a packet capture yet. But I will.
It is a layer 2 trunk to the distribution layer.
The DHCP server is on another VLAN and has the ip-helper configured on the VLAN interface.
