Cat Express 500 & 2950 RSTP & PVST

Hi,
I have a Cat 500 connected to a 2950,
on a 802.1q trunk.
The Cat 500, seems to be running RSTP and the 2950, is capabale of only pvst.
The port seems to go into blocking state in the Cat 500.
After changing the Cat 500 to run IEEE STP, the problems I was having with ports being blocked disappeared.
Can anyone suggest what is the best approach when running a Cat 500, connected to a Cat 2950 ?
Do I need to enable MST on the Cat 500, so that it can interop with 2950 ?
If I have only thses 2 switches, is the best option just setting both switches to use the same STP mode ?
Thanks

YES,
the best option is to use the same STP type/mode throughout your environment.
rapid-PVST+ is interoperable with PVST+. when the two exist, the rPVST+ switch reverts to PVST+ unless you are running dual STP instances, one for rPVST+ and one for PVST+.
again, if you can run the same STP mode, please do.
please see the following link for much more STP info:

802.1X and CAT Express 500

Hi guys,
I want to know if the Cat Express 500 support dynamic vlan assigment through 802.1X.

Hi,
You can do the vlan arrisgnment using 802.1x on CE500. The configuration for 802.1X and Radius authentication server can be done with the help of Cisco Network Assistant (CNA). In the menu Network Security Settings you have to put the
security level on high. There is the possibility to configure the IP address of the RADIUS server and the RADIUS key.
In case you don?t have the CNA, you can download it for free from:

Cat express 500 and AP´s

I have 1 1200 AP, 1 Cat express 500, 1 7920 ip phone and a notebook. How do i configure the switch port so that i can have different wireless vlans for voice and for data?
For the phone to join an ssid it must be an infrastructure one. For the ssid to be infrastructure, the vlan must be native. I can´t choose the native vlan in the cat express 500, only the vlan 1 can be native and that is not my voice vlan!
With other switches this works just fine......Any suggestions of how to configure it????

Basically at this stage with the Cat 500, there is no way to assign a port natively to the "Cisco-Voice" VLAN. Basically cisco screwed up completely here, and I believe will fix this in a future software update.
However as a workaround you can ignore completely the Cisco-Voice VLAN, create a new VLAN (I used VLAN3) and assign this to the port for the 1200AP. Change the smartport role for each "IP phone & Desktop" to "Switch" - this allows a trunk between phone & Cat500 and will allow the phone to communicate on VLAN3 with the AP (if you set phone to VLAN3)
EDIT - Sorry I just re-read your message and it sounds like you need to set-up the port to the AP as a SWITCH, because you want multiple VLANS on the wireless - sorry not familiar with this AP, but using 'switch' should trunk the VLANs no bother as long as the AP supports it.

Cat Express 500 Auto-MDIX

I am trying to connect a Cat 500 Express to a 2950, using a stright-through cable.
If I enable auto-mdix on the Cat 500, I have to enable auto speed and duplex settings.
If I do this, I get a duplex mismatch.
Can i set the auto-mdix to work, without having to auto-negotiate the speed and duplex settings ?
On the 2950, the settings are 100/full
Thanks

BY default CE-500 is auti-mdix & u need not make any changes on duplex settingz. bcoz i never faced such problem by connecting my CE-500 to 2950, juz a straight cable connecting from CE-500 gigabit to 2950 gigabit. thatz it, i didn't get any duplux mismatch, try to check once again in 2950 that every thing is set auto(duplex & speed)

Cat Express 500 Slow Admin and keeps crashing

Hi
I have a customer with 2x WS-CE500-24PC and 2x WS-CE500-24TT
They are brand new and most ports are set to IP Phone smartports with 2 as wireless access ports and 1 router port with an 1841 in it. They are all uplinked together.
When first rebooted http admin access is ok but after a couple of minutes it becomes un-usable and then eventually the switch reboots (does this 2 times a day).
i have 1x WS-CE500-24LC and this is fine never misses a beat, its also linked into the same network.
here is where it gets crazy, if i set all the ports to other its fine, but i cannot use any of the phones because it does not put them in the voice VLAN.
Any ideas it driving me and my customer mad.
Andy

Try to disable the arp inspection feature in the CE500's CLI.
This feature can sometimes introduce some disconnectivity on this particular switch.
Enter the following line in your browser:
http://10.0.0.1/exec/cli
ip arp inspection vlan 1-1024
ip arp inspection vlan 1-1024 logging acl-match none
ip arp inspection vlan 1-1024 logging dhcp-bindings none
If your switch uses a different ip address than please use that address. After you applied this, it will take about 15 till 20 minutes to decrease the cpu utlization.

Express 500 - IP Telephony problem

Hi, i have a problem in a site that is in a mine, there are under extreme conditions, the site is 3000 meters over the sea level. There are deployed 9 catalyst express 500 and unti yesterday all was ok, suddenly the calls begin to drop down between calls in the site and over the link (satellite) to the other site. Also, the ip phones can not stay registered to the call manager, they are booting continuosly.
Any suggestion or maybe you need more inforation.
Thanks in advanced ...
Jose

What's the IOS version you're using on the CAT 500? Have you configured a flat VLAN for everything or used the Cisco-Voice VLAN for the PC+IP Phone smartports??
I'd also check the 'status' to which you've assigned the Call Manager Server (Should be set to Trusted to give it the necessary QoS).

I need online Configuration Guide for Catalyst Express 500 Series Switches

Hi Mates,
Please is there an online help page for 500 series catalyst
I have this one for IOS 12.2(25)FY http://www.cisco.com/en/US/products/ps6545/products_configuration_example09186a00806da6c9.shtml
but I need more detailes like IOS 12.3(7)JA for Aironet 1300 http://www.cisco.com/en/US/products/ps5861/products_configuration_guide_book09186a00804ebd50.html
Regards
Saher

I'm afraid there is not such document for IOS 12.2(25)FY since the Catalyst Express 500 Series switches are manageable through the GUI Device Manager or Cisco Network Assistant.
I have also found key features and standards supported for that release:

Hope this helps

Catalyst Express 500 Series WS-CE500-24PC PoE

Inline power (PoE)
Can some one confirm PoE Spec's and a little confused reading the spe'c
the spec say
●All 24 PoE ports on the Cisco Catalyst Express 500-24PC can supply up to 15.4W
(IEEE 802.3af standard maximum) of power over Category 5 cable, for a total of 370W
of inline power.
● Both the IEEE 802.3af PoE standard and Cisco prestandard inline power are supported
I have cisco 7940G witch are Prestandard so this switch will power the Phones on PoE ?
does not say it will supply PoE for Prestandard Phones just say its Supported
Thanks

Hi Colin,
Yes, the switch will power prestandard 7940s. Specs state it works on both 802af and cisco prestandard poe.
Best,
David

Vlan 1 in cat exp 500

What is the real name for the vlan 1 in the Catalyst Express 500 switch?.
im receving vlan name mismatch between an ASA5505 and a CE500.

The switch ships with a default VLAN to which all the switch ports initially belong. The switch supports a maximum of 32 VLANs, including the default VLAN. Using only the default VLAN might be sufficient based on the size and requirements of your network. We recommend that you first determine your VLAN needs before you create VLANs.
Cisco Catalyst 500 series switches work in VTP Transparent mode. VLAN creation, modification, or deletion done on this switch does not affect the other switches in the domain.

Stacking a non-Cisco Switch with a Catalyst Express 500 switch

We are using a Cisco Catalyst Express 500 Ethernet switch and need to add another switch to get a few more ports. Is is possible to stack a Catalyst Express 500 Ethernet switch with a non-Cisco Ethernet switch. If so, is there any Cisco documentation telling how to do this?

If by stack, you mean connect the two switches via Ethernet ports, yes you should be able to do that. Depending on the port capabilities of the switches, and whether they have any special uplink ports, you might need to use a different Ethernet connecting cable (cross-over vs. straight thru).

POE for Aironet 1131 on Catalyst Express 500

Hi all,
we are using 3 AP Aironet 1131 (Version 12.4(10b)JA3) in a WDS. All are connected to a Switch Catalyst Express 500 to receive their Power. The Problem is they work for some time and the the AP reloads without further errormessage.
Speed and Duplex mode are fixed on Switch and AP-Side. Does anybody now this problem or can give me a hint?
Thanks in Advance
Alex

This can happen if power settings are configured incorrectly on the AP. Ensure that the correct parameters are configured. Here is a link which explains how to configure power on APs.
http://www.cisco.com/en/US/docs/wireless/access_point/12.3_2_JA/configuration/guide/s32frst.html#wp1103896
Also, try disabling CDP and check if you are seeing the issue again.

AP1200 and Switch Cisco Express 500

Hi,
We have an AP1200 (port 1) attached to a switch cisco express 500,in this switch we are using a Vlan and we have a DHCP server.
The problem is when a new PC tries to connect to this AP, it takes to much time to assign the IP address, and in other cases the PC is disconnected from the System constantly. Do you know wich could be the problem ?

It sounds like it could be a problem with your wireless signal - have your tried doing a carrier busy test on the AP to check for interference?

Catalyst Express 500 24TT linked to an unmanaged switch

I'm trying to hang an unmanaged switch (netgear FS108)off this switch but with little success. I've configured the port on the Express 500 as a switch port but nodes connecting through the unmanaged switch can't fully browse nor can they receive DHCP addresses. Is there someway to make this work or are these Netgear switches simply not supported and won't work period?

Yup, that worked. I assume the same issue applies to the 'server' port setting. If I've created multiple virtual servers each with their own unique IP address, the 'server' port settings spits back an error not allowing multiple connections through the same port.

Catalyst Express 500 802.1q with non-Cisco Phones

This weekend we spent hours trying to get 802.1q tagging to work on a VLAN with ShoreTel phones. The user interface on this switch seems to only allow "Cisco-Voice" VLAN, without any specifics. This didn't work. The specs on this switch say that the .1q is supported, but we couldn't figure it out. The more expensive switches were easier to configure for Voip QoS.
Can anyone advise me on the tricks to getting this to work with the lower end Catalyst Express 500? Or does this switch only support 802.1q with Cisco phones?

Cisco IP Phone uses CDP to let the ip phone know what vlan it's suppose to be (via voice-vlan). shore tel would definitely not use CDP since CDP is cisco proprietory, so it's voice vlan must be defined on it, I rememer Avaya being the same way. So, having said that, just make sure that the Shore tel Ip phone are in the right vlan. what does not work anyway? shore Tel IP Phone will not come up? Will not get it's configuration from it's software PBX? Use the smartport configuration on CE500.

Catalyst Express 500 - Cannot configure

I just reset the Catalyst Express 500 (WS-CE500-24TT V01) switch back to factory default by using the directions Recover the Switch Software in the manual.
After rebooting I cannot get to into the Setup Windows. It does not come up, either automatically or typing a URL in Internet Explorer. I went thru the trouble shooting section on the manual and I am having no luck.
Originally when I set up the switch and I was able to get to the Setup window thru Internet Explorer, however the configuration did not save properly or seemed so. After I configured and rebooted I could not access the management screen using IE.
I rebooted hit the setup button and then could not get in, I even typed a domain name such as cisco.com, this also did not work. I reset the switch as stated above to factory default. I have Pop-up blocker off, no firewall is on.
Do you have any ideas on how to resolve the problem? Bottom line I cannot get into the management console to configure the switch.

Hello,
this is just a guess, but if you are using IE6, you might want to install the Microsoft Virtual Machine, you can download it at
www.craftof.com/VirtualMachine.asp
Uncheck the Sun Java VM in IE6...
Regarding the recovery procedure, did you use exactly the one described below ?
