Subject: pxe & spanning tree
Date: 13 Jun 2003 14:38:08 +0200
Hi
I've recently installed an LTSP on RedHat 9. I'm using Via Eden based
"thin clients" with PXE booting, which in turn boot Etherboot to boot an
LTSP kernel. The onboard NIC on the Via's are Realtek's 8139.
When I boot the thin client over a crossover link everything is working
just fine. However, when I use our Cisco Catalyst 2900 Switch I don't
even get an IP address and get the following error message: "PXE-E51: No
DHCP or proxy DHCP offers were received. PXE-M0F: Exiting PXE ROM" and
subsequently it attempts to boot from disk which isn't there.
According to previous posts this means I should enable spanning-tree on
the switch, but it already is, as you can see here:
Switch>sh sp s
UplinkFast is disabled
PortFast BPDU Guard is enabled
Name Blocking Listening Learning Forwarding STP Active
-------------------- -------- --------- -------- ---------- ----------
VLAN1 4 0 0 8 12
-------------------- -------- --------- -------- ---------- ----------
1 VLAN 4 0 0 8 12
I don't see any DHCP requests on the server either.
Does anyone have any suggestions?
tnx
tom
