Two thing to check :
1. Have you enabled portfast on the user interfaces. The chipset that
Cisco and most switch vendors use takes to long in checking for spanning
tree loops that the IPX logins timeout.
2. The 4006 creates port groups for every 4 ports. Even if all the
ports are in VLAN1 and PORTFAST is turned on devices that are more that 4
ports from each other can't see each other. Check the set port channel
statements. It looks like from the config that I have we had to do a set
port cannel 2/1-48 mode off. To resolve this issue last year.

Subject: Cisco 4006
I have a scenario where a 3com Netbuilder Router has
been replaced by a Cisco 4006 switch without a routing
feature card. The routing from the 3com Netbuilder
has been moved to an existing 6509 with an MSFC.
Users who now traverse the 4006 to get to Citrix and
AS400/Notes servers off of the 6509 are unable to
connect or login. They either hang or timeout. Ip
connectivity (pings, traceroutes) to those servers
works fine. The 3com Netbuilder was also configured
with ip forwarding for udp ports 67, 68, 137, 138.
This is on by default on the 4006. Ip helper
addresses have also been configured on the 4006. Any
ideas?
