Were people on other VLANs able to get addresses assigned? Is there a
filter preventing the return packet assignment? Try shutting/no-shutting
the interface.
However...
Sounds like that bug is hit on the head by the description... upgrade your
IOS version.

Subject: vlan and dhcp-------help
at our site we provide ip adresses to workstations via dhcp. We ahve around
10 Vlans . I have the vtp domain on a CAT 6509. RUNNING IOS 12.0(7)XE. on
its msfc's (2). The Core switch trunks to various Cat 4006's. Users on a
certain vlan 106 coamplained that they could not get network connectivity
as they were not agetting an IP adress. I connected my laptop to the switch
on wich the ports were assigned for valn 106 and was unable to get an IP
address. Hower when I configured my laptop with a static IP I was connected
to the network. I configured a port for vlan 106 on another cat4006 and got
the same result.
I have
* Portfast enabled,
* port channel mode disabled
* and trunking for ports disabled.
* Also I did not see any mismatches. of ports.
* also ther ip-helper address is setup on my MSFC's
Cisco believes that there is a bug in ios ver 12.0(7)xe and told me to
download the new config 12.1(5) that has the fix---as explained below
Release Notes
Forwarding of bootp/dhcp address request UDP packets fail
because of
encapsulation failure.
Workaround: Use Cisco IOS Release 12.0(5)T.
Does anybody have any suggestions?
