By the way, where is the DHCP server, if your DHCP is located in the other
vlan, you need add ip-helper address in your router.
Hope this help

This is definitely a spanning tree issue. Enabling port fast on the access
ports will get rid of the problem.

Strongly in favour,
A similar problem occurs in an IPX environment.
Make sure all Servers/Clients are 'portfast' and
switch/switch disable 'portfast'.

What you were told sounds correct to me. If you have a port that is only
connecting to workstations or servers then turn on portfast for that
port. That will prevent you from having problems with DHCP.

A few comments. First, not being able to obtain a DHCP lease upon initial
boot isn't "a problem related to Cisco's Spanning Tree Protocol"
implementation. Cisco implements the IEEE 802.1D STP algorithm that
specifies
when a port becomes active, it must go through the blocking, listening, and

How exactly do you configure portfast on a 2924XL-EN? Just wanna try it

A similar problem happens with AppleTalk too. That's what we get for

Oh, speaking of AppleTalk. We've got a customer (not mine, but one of the
engineers working the account bounced this off me): They claim their new
Macs can't access the network if Spanning Tree is enabled. Supposedly this

It's the same old thing. You gotta turn on portfast.

If it really takes 15-30 seconds for a switch to forward even when portfast
is enabled, I can see why AppleTalk nodes would hate this. An AppleTalk
