We have a situation where a customer replaced their old Cisco switches
for new Cisco 7010. And now Sunray DTUs on one of the subnets do not
get DHCP addresses. While other DHCP clients (PC's) work well on this
subnet.
1 other subnet works fine even for Sunrays.
Anyone encountered anything like this before ?
Yes, although I don't know if the switch was to blame in our case (and I
don't know the switch model). University networking sometimes uses
"dynamic jacks" that assign networks by MAC. It appeared to affect all
35 Ray 2, although the Rays would sometimes work. Removing dynamic
eliminated the problem.
We did not debug sufficiently to understand why Rays are special. As in
your report, other systems connected. This list has said that Rays can
present multiple MACs at power-on, but networking was skeptical that
this was an explanation.
