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

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

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:

Catalyst Express 500 series connection problems

Hello! our company is currently using two 500 series switch connected to eachother using the g1/1000mbits port, a cisco router is also plugged in to one of the switches for broadband internet access. After deployment the following problems came up, we are unable to use our wireless access point even when the port is set up as being "access point" using the smartports feature, we simply cant ping the access point no matter what port type we set on the switch and we keep having the error message on the router that it has denied connection from that device, my feeling is that for some reason i'm not aware of the router is blocking certain devices to transfer data no matter what type of port we define on the smartports feature. I cant find anyway or option on the router software to disable this blocking or filtering of the data in order to connect any devices i want normally without any restrictions. for some reason the switch is not accepting connections from the access point...
Any help would be much appreciated.

Hi, well, i did disabled STP but it didnt help, i'm going to post the network topology more exactely and the settings being used so its easier to get any help as i think i missed some points about our network :) ....so here it goes :
1. All the devices and client computers are using fixed ip addresses on the range 192.168.254.x
2. Topology :
Switch number 1 connected devices:
17 client computers connected
1 printer
1 cisco router (with dhcp disabled and using fixed ip too)
1 Netgear AP using set with DHCP
Switch number 2 connected devices:
10 client computer connected
Switch 1 and 2 are connected using the G1/1000mbits uplink port
Settings being used on BOTH switches (they are both catalyst 500,same software version) :
- default vlan1 is set and enabled
- STP enabled
- IGMP snooping enabled
- all ports are enabled and set to auto mode for speed and duplex
- port Gi1 that is used to connect both switches is set as "Switch" type with smartports.
- gateway (cisco router) ip address set
- security set to "low"
- STP settings on switch 1:
currents roots: VLAN1 , priority:32768 , root port: fa24 (where the router is connected), route path:38
- STP settings on switch 2:
currents roots: VLAN1 , priority:32768 , root port: Gi1 (uplink to switch 1), route path:42
switch 1 specific settings:
- the port where the AP is connected is set using smartports as "Access Point" and the port where the printer is connected is set as "Printer" also using smartports on the switch device manager software.
- the port where the cisco router is connected is set as "router" with smartports
Facts:
- I am able to ping all the devices on the network from any computers connected to both switches.
- I am able to ping the printer from any computer connected to both switches as well.
- When AP is connected directly to the cisco router wireless clients have access to internet with no problems
- all wired client computers on both switches connect to the internet using the router without problems.
Issues:
- Cannot ping the AP from any client computer on the network
- When printing from Switch 1 clients everything goes well, but when i print from clients on Switch 2 i am unable to print as its unable to connect to the printer, however i can ping the printer on the command-line !
- When i try to plug in the network cable from the AP to its designated port on Switch 1 the network crashes !
Error messages:
When trying to print from clients on Switch 2 or when try to connect and use AP on switch 1 i get or "access denied to device connecting to portxx" or i get an STP blocking error .
Hope the picture is clearer now.
thanks once more.
Fernando.

Change default VLAN on a catalyst express 500 series.

Hi. On one of our networks we have a CE 500 series 24 port switch (the one with just 4POE ports). As it hasnt got a proper console interface, is there a way of changing the default data vlan from 1 to 2 without having ro reset it?
I've logged into the web page on it but I cant change my default data vlan ID because its greyed out.. Does the default data VLAN ID need to be specified on installation?
Thanks

Catalyst Express 500 series trunking problem

We have a cisco 2801 router and CExpress500 switch. The router is connected to switch over the port role "switch" and native vlan no is 1. The router is configured as this:
interface FastEthernet0/0
no ip address
duplex auto
speed auto
interface FastEthernet0/0.1
encapsulation dot1Q 1 native
ip address 192.168.110.4 255.255.255.0
no snmp trap link-status
interface FastEthernet0/0.184
description vlan184
encapsulation dot1Q 184
ip address 192.168.184.1 255.255.255.0
no snmp trap link-status
Users can reach the native vlan but they cant reach other vlan. Any comment?

The port on the CE500 should be set as a router, otherwise DHCP from/through the router will not work. Setting the port as "trunking" is not possible on a CE500 switch; you must choose predefined smartport types.
Set up your router port as a Dot1Q interface with sub-interfaces and make sure the native VLAN matches on both devices.

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.

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 ?

Need that a Cisco Catalyst Express 500 behaves as cheap switch

Need that a Cisco Catalyst Express 500 behaves as cheap switch.
I happen to have a surplus of CE500 and i need to use one as a layer 2 cheap switch (unaware of lan and with port protection off).
How can i achive this?

That's the thing, i'm sitting on several CE500, i'm not allowed to buy a cheap one right now, i have to use what i have, i know is too much but it should work and i read that it does, there is only one problem, i need to plug a access point to the CE500 that connect this section of my network to the rest.
I can't make the CE500 to work with this AP, a cheap switch i had there before worked properly.

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).

Catalyst Express 500 Switch and wlan roaming problem.

Hi everybody.
We are using Catalyst Express switches and air-1121G for a wlan network covering a hotel. When we set the smartport-setting on switch to "access-point" users cannot move from one access-point to another. Setting the smartport-role to "other" solves the problem.
Has anybody made the same experience ?

Hi
This is a known issue and the workaround you have used is the best but
this issue has been solved in the new IOS release
i would suggest you to upgrade the IOS for the Catalyst 500 and this should solve the problem
the IOS code is CE500 IOS 12.2.20.SEG
Hope this help

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 complains about undersize frames

Hi,
The exact switch model is WS-CE500-24PC.
It claims, that devices connected to its ports are generating undersize frames. The connected devices are IP phones with PCs. Moreover I've got messages about undersize frames on Gigabit ports, which are configured as GigaChannel and are connected to another WS-CE500-24PC. The interface counters are showing, that a lot of undersize frames are received, not send. I think, that such big count of undersize frames severely degrades the performance of the switch. Is there any way to diagnose this problem?
PS When the same endpoints are connected to a "normal" switch, like 2950 or 3500, there is no any problematic frames counted in the output of the "sh controllers ethernet-controller" command.
Thanks and regards,
Denis

When the switch receives a 60-63-byte dot.1q encapsulated frame, it counts it as an undersize frame, but it will forward the frame correctly. There is not workaround for this issue, since the problem is not in the switch, the switch is only reporting that it is receiving this frames in the interface, the frames are generated by the connected device and not by the switch. If you do not experience network connectivity issues in the interface reporting this issue I believe that the issue can be consider as a cosmetic.
