comment VTP trunking not working for Cisco 4948 switch
@JohnP, it shouldn't be. I don't recall for the 4948, but the 3750 does have auto-MDIX and only one side needs it. Did you try a different cable and different ports on each switch? You could also try entering switchport on each interface to ensure it isn't operating as a L3 interface.

Looks like you may not have an active link connecting the two.

@JohnP, can you add the output from sh cup neighbor? Since you mentioned the one interface is down, need to check if you have a link between the two.

John, you state that you are connecting the 4948 to 3500s, but your VTP server is running a 3750 image. Is this really a 3750 or a 3500 as indicated in your post?

@joeqwerty, he already stated he verified the password is correct on both switches and the coding revision is clearly indicated as 0.

comment cisco ip helpder-address not working
Why are you configuring a DHCP pool locally on the switch? You shouldn't have DHCP running on the switch unless you want it to provide DHCP services. Also, your debug doesn't show a DHCPDISCOVER, so there was nothing to start the relay process. AFAIK, a Cisco device won't relay a DHCPREQUEST for an IP it is configured to provide by DHCP.

comment Same number of clients - multiple WAPs vs Single WAP
In basic terms, an RF channel can only have one 802.11 device communicating on it at a time in the same area. As such, it is a finite resource that is shared among all devices. Air time generally refers to the channel utilization, either in total, in use by a device (or group of devices), or type of traffic and is often used when trying to make more efficient use of the RF medium.

comment How can I avoid Mac OS X temporarily setting its IP in the “link-local” range (169.254.x.x) at boot time?
@Pickles, the problem with falling back to its "last-good" address is that the last address may now be in use by another device and then cause an IP conflict on the network, which is potentially far worse.

So, to paraphrase your answer and comment, using the reserved addresses is a violation and using a manual assignment from the generated range is a violation. So then the answer should be "No, this is a bad idea. You need to find a better solution." If people were to just ignore the standards and specifications when they are inconvenienced by them, then the standardization, inter-operation, and the whole foundation of networking/the Internet are all at risk..

Why would you suggest using the two ranges that IANA has reserved for future use? That seems to be bad advice in case the IANA chooses to make use of those reserved ranges for some reason.

If they are only used to communicate from service to service within the same host, is there any reason you wouldn't use a loopback address?
