Power but no network after upgrade to gigabit phones

whostheman — Wed, 23 Feb 2011 03:58:30 +0000

During a recent upgrade we went from 100 MB VoIP phones to Gigibit VoIP phones this caused some issues primary related to the wiring in the building. While all of it was either 5e or 6 we ended up having a lot of bad jacks that needed to be re-jacked due to damage from chairs, desks, cables, keystones pushed or pulled out, and general wear and tear. The big issue was everything was working fine prior to the upgrade but after the upgrade some ports would power the phones but they would show not connected to the network at all. These are steps I went thru on our Procurve 3500yl / 5400zl / 8200zl switches to identify the problem ports.

From a enable prompt

# show power-over-ethernet brief | include Delivering

This will show all ports actively giving power

# clear statistics all

This will clear the statistics on all ports

# show interface

This will show all the ports and the key is looking for a port that shows having power but has no Total Bytes or Total Frames.

This is most likely an issue of gigabit not being able to be negotiated on the cable. While the best solution is to identify the wiring problem that doesn’t help the users that phone/equipment isn’t working. The second best is to set the port to 10/100.

# conf

(config)# int 11

(eth-11)# speed-duplex auto-10-100

(eth-11)# exit

(config)# exit

Trust but verify

# clear statistics all

This will clear the statistics on all ports

# show interface

And of course while the best solutionis to have all the jacks checked that could take sometime so make sure you save and backup your config.

H3C Shortcut Keys

whostheman — Mon, 31 Jan 2011 23:45:56 +0000

Like many things in the H3C world shortcut keys are not well documented here are the one I use every day. I will add more as I find them.

Ctrl-K	display ip routing-table
Ctrl-O	undo debugging all
Ctrl-G	display current-configuration
Ctrl-A	Beginning of Command Line
Ctrl-E	End of Command Line
Ctrl-N	Next Command in the history buffer
Ctrl-P	Previous Command in the history buffer

WPA-WPA2 Radius setup for EAP using IAS with GUEST SSID on H3C Wireless Controller

whostheman — Sun, 30 Jan 2011 17:28:51 +0000

Since the even with the configuration guides I found and uploaded configuration of the Wireless Controller still has some details not in the guides. I thought I would upload my confguration of my wireless as an example. I am using EAP based WPA/WPA2 security to a Windows 2003 Radius Server specifically an internal PKI . This is based on an existing IAS Server infrastructure and just adding the Wireless Controller as a new Radius Client. I have two SSIDs one for guests called GUEST-WIFI on an internet access vlan (VLAN 80) and a SECURED-WIFI for end-users on VLAN 1 using WPA/WPA2.

On the controller the following needs to be configured:

domain default enable system

port-security enable

dot1x authentication-method eap

radius scheme ias

server-type extended

primary authentication IASSERVERIP

primary accounting IASSERVERIP

key authentication SHAREDKEY

key accounting SHAREDKEY

timer realtime-accounting 3

user-name-format keep-original

nas-ip ACCESSCONTROLLERIP

undo stop-accounting-buffer enable

accounting-on enable

domain ias

authentication default radius-scheme ias

authorization default radius-scheme ias

accounting default radius-scheme ias

access-limit disable

state active

idle-cut disable

self-service-url disable

wlan radio-policy rp

beacon-interval 500

wlan service-template 1 clear

ssid GUEST-WIFI

bind WLAN-ESS 0

user-isolation enable

service-template enable

wlan service-template 2 crypto

ssid SECURED-WIFI

bind WLAN-ESS 1

cipher-suite tkip

cipher-suite ccmp

security-ie rsn

security-ie wpa

service-template enable

interface WLAN-ESS0

port access vlan 80

interface WLAN-ESS1

port-security port-mode userlogin-secure-ext

port-security tx-key-type 11key

dot1x mandatory-domain ias

wlan ap autoap model 7760_2750 id 3

serial-id auto

radio 1

radio-policy rp

service-template 1

service-template 2

radio enable

On the IAS server a new radius client needs to be configured.

3CRUS2475 Discovery Process by H3C/3Com 7760 Access Point

whostheman — Sun, 30 Jan 2011 00:33:04 +0000

One of the issues I found with having H3C/3Com now HP products over the last few years is the lack of support for senarios that are described but never documented. While desciption of features exist configuration guides or FAQ seem non-existent. I recently purchased a S7500 controller blade at work for our new core to move over our existing 7760 series Access Points from 3CRUS2475 switches over to a more robust solution designed to handle our 70+ APs. I just wanted to take this time to document the way 7760 discovered the 3CRUS2475.

3Com Access Point sends a UDP port 42004 to broadcast searching for Wireless Switch with the model number of the access point

Detailed H3C WX Access Controller Discovery from a HP/3Com 7760

whostheman — Thu, 27 Jan 2011 18:54:20 +0000

One of the issues I found with having H3C/3Com now HP products over the last few years is the lack of support for scenarios that are described but never documented. While desciption of features exist configuration guides or FAQ seem non-existent. I recently purchased a S7500 controller blade at work for our new core to move over our existing 7760 series Access Points from 3CRUS2475 switches over to a more robust solution designed to handle our 70+ APs. The first step is to update the managed firmware in the device from the firmware that ships meant for management by the Unified Wireless Switch 3CRUS2475 to the H3C fit managed mode. I just wanted to take this time to document the differnet ways it seem you can configure these to discover the Access Controller.

IPv4 Broadcast Discovery 255.255.255.255 from/to port 12223: 3 packets detailing that it is a discovery packet and the model and serial number of the device.
DNS Discovery for hostname 3ComWLC: 1 DNS request stops if no name found
IPv6 Multicast Discovery FF02:1 from/to port 12223 : 3 Packets again detailing that it is a discovery packet and the model and serial number of the device.

This then repeats if no controllers are found. The additional options for manually configuring the device exist:

<7760_2750> sys

[7760_2750] wlan ac ip “ip address”

or

[7760_2760] wlan ac ipv6 “ipv6 address”

[7760_2750] quit

<7760_2750> save

Hope this helps….

Supported HP / H3C / 3Com Access Points on WX6000 Access Controllers

whostheman — Thu, 13 Jan 2011 02:32:08 +0000

I recently purchased a H3C Wireless Controller for the HP A7500 switch. One of the issues I found out was with the HP consolidation of the product lines from Colubris/3Com/H3C I couldn’t get a answer on what was supported. Here is a list of access points that should be supported:

JD446B - HP A-WA2110 Single Radio 802.11a/b/g Access Point

JD451A - HP A-WA2220 Dual Radio 802.11a/b/g Access Point

JD445A - HP A-WA2612 Single Radio 802.11n Access Point

JD472A - HP A-WA2620 Dual Radio 802.11n Access Point

JD452A - HP A-WA2610E Single Radio 802.11n Access Point

JD453A - HP A-WA2620E Dual Radio 802.11n Plenum Access Point

Ironically the following two are supported despite being some of the oldest and are not H3C. I anticipate these will soon be discontinued:

JD015A - HP A7760 Single Radio 802.11a/b/g Access Point

JD016A - HP A8760 Single Radio 802.11a/b/g Access Point

Discontinued but still should work:
3Com 3150

I am anticipating that some of the nicer E-Series Wireless will be supported hopefully the MSM317 would be sweet.

HP / H3C Hidden Commands
