Cisco Switching/Routing :: Could Not See RPS Status On WS C3750G 48PS

Dec 7, 2011

We recently connected a RPS 2300 to our switch WS-C3750G-48PS-E with IOS c3750-ipservicesk9-mz.122-53.SE2.bin.However i do not see any RPS details in the"show env" output.I believe i should get the RPS Name and its Serial and the port number in the output, but i am not finding it in the output. I did reload the switch but still couldnot get this udpated.

Cisco Switching/Routing :: Stacking WS-C3750-48PS-S With WS-C3750G-48PS?

Apr 17, 2013

I have production stack in the following config:
 
Switch   Ports  Model              SW Version              SW Image
------   -----  -----              ----------              ----------
*    1   52     WS-C3750-48P       12.2(25)SEE4            C3750-IPSERVICESK9-M
     2   52     WS-C3750-48P       12.2(25)SEE4            C3750-IPSERVICESK9-M
 
I want to add 3-rd switch to it:
 
Switch: WS-C3750G-48PS   12.2(25)SEE3           C3750-IPSERVICESK9-M
 
Will this configuration work? My main concern is IOS difference?

Cisco Switching/Routing :: WS-C3750G-48PS IOS Upgrade

Sep 11, 2012

I am in the process of upgrading our stack of 4 switches consist of WS-C3750G-48PS. Upon reading release notes found that there are two versions of release notes 1 day apart, the one 02 Sep 2012 saying that WS-C3750-48PS is not supported in this version. Then in release next day 03 Sep 2012 that note has been removed. Which one is correct. Is it supported with my model of switch or not. Also unable to update boot path in the stack switches, "switch all" is not supported in the current IOS. Any other way to update it. Master switch has new boot path but unable to change in slaves.

Cisco Switching/Routing :: ASA 5505 Connected To WS-C3560G-48PS

Nov 2, 2011

I recently removed a catalyst 2950 switch code version: c2950-i6q4l2-mz.121-13.EA1 ?I had an ASA 5505 connected as a switchport access to the 2950 on port 44.  We will call the VLAN that the ASA sits on: VLAN 404.  The 2950 had a trunk to our catalyst 6509 distribution switch carrying that VLAN 404.  We also have a another VLAN for computers that sits on: VLAN 129, this is a standard DHCP vlan and it accounted for the rest of the switchports.  The 2950 also has this trunked to our 6509 distribution switch.
 
Everything was working fine with that setup.After replacing the 2950 with a 3560 we started running into problems.  The 3560 was configured the same exact way as the 2950.  What was happening is that computers that sat on VLAN 129 started experiencing packet loss and were unable to work.  It's as though the ASA was taking over the switch. 
 
Is there a protocol that is enabled by defult on the 3560 that would do this?

Cisco Switching/Routing :: 3560G-48PS-S - PoE Lockout After Power Outage

Oct 27, 2011

We had some problems with 3560G-48PS-S switches and PoE for our phones. IOS is 12.2(50)SE3. There were some problems after power outage. The switches didn't reboot because we have two eletric circuits. But after the problems we had no PoE on all ports.
 
The switches logged to following syslog message:
 
%ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Gi0/17: Power Controller reports power supply VDD under voltage
 
I can't find any informations in the error message decoder for that. But there was another thread here with quiet the same message, but another problem regarding RPS2300.
 
After reloading the device all works fine again. The workaround with the commands "power inline never" and "power inline auto" I didn't know till today.
   
Some information about that syslog message?
 
My guess is that there was a voltage swing and the switch powered down its supply? Is that possible?

In my office we bought 7 cisco 3750X - 48PS switches. We configured Data Stacking between those switches. We also want to configure Power Stacking between those 7 devices.
 
I found in the Data Sheet that we can only configure 4 devices in power stacking at a time. If it is like that how to configure the rest of 3 devices. Need configuring power stacking between those devices in a better way..

power stack cable part no we have is

Cisco Switching/Routing :: Upgrading WS-C3750G-24TS-E1U To 15.0.1-SE2?

Feb 17, 2012

I have the following switch:

#show version
Cisco IOS Software, C3750 Software (C3750-IPSERVICES-M), Version 12.2(52)SE, RELEASE SOFTWARE (fc3)
Copyright (c) 1986-2009 by Cisco Systems, Inc.
Image text-base: 0x01000000, data-base: 0x02C00000

BOOTLDR: C3750 Boot Loader (C3750-HBOOT-M) Version 12.2(44)SE5, RELEASE SOFTWARE (fc1)
 
 [code]...

I have downloaded c3750-ipservicesk9-mz.150-1.SE2.bin and I want to upgrade iOS to this image.
 
I have a few questions related to this:
 
1. Is my switch model compatible with this iOS version?

2. Do you recommend the upgrade? Does it bring some notable features?

3. Can I upgrade for free or do I need to buy some license?

4. I also want to upgrade/add the crypto image, can I add crypto for free or some license is required?

5. I have remote access to my switch via the console cable which plugged into machine1. But machine1 is connected to network via the same switch. I am accessing machine1 via SSH, and then the switch via console cable (minicom on CentOS). Is there an upgrade procedure for this kind of situation that also has some fall back (like reboot in X minutes and load the previous image) if the upgrade goes wrong?

Cisco Switching/Routing :: WS 3560G 48PS Invalid Dhcp Options And Unable To Parse

Jan 13, 2013

I have configured DHCP snooping on a WS-3560G-48PS running IOS 12.2(58)SE2 ipservicesk9 variant.When I enable DHCP snooping clients don't get IP addresses, when DHCP snooping is disabled, everything works fine.I have set up a SPAN port and run a capture (attached) on the traffic. Wireshark notes the Seconds elapsed field appeared to be encoded in little-endian but only on some packets. Apart from that, I can see nothing wrong with the DHCP Offer responses from my DHCP server.Attachment config.txt contains the interesting parts of the  configuration. Please note g0/32 has been set to ARP inspection trust as  without working DHCP snooping it would require a static bind.Is there any way of figuring out which option can't be parsed? Is there a way to force forwarding of unparsable DHCP packets while still running DHCP snooping?

Cisco Switching/Routing :: Inter Access Switch Fiber Connectivity 2960-48PS

Jan 16, 2012

I had a strange issue yesterday when onsite installing a new access switch.Port capacity full on a two switch stack of 3750 x48 PS switches (WS-C3750- 48PS-E)- New 2960 x48 PS - WS-C2960S-48FPS-L racked, with the plan of using it just as an edge switch via SFP Stacking cable.Setup the two connecting ports with simple initial config: - switchport mode trunk- no encapsulation option on the 2960, default dot1q- dot1q set on 3750 port- no shut on both sides.Connected the SFP Stacking cable but it didnt work:- %PHY-4-SFP_NOT_SUPPORTED: The SFP in Gi1/0/1 is not supported
 
This is ok as I had a backup:- Next step tried using 2 x Short Haul SFP SX GBIC's with LC - LC OFNP 50/125 fibre patch lead  - no joy- Extra backup of 2 x Long Haul SFP LX GBIC's with the same fibre patch - no joy- Checked the fibre and it was not a cross over so transmit and receive going down the same side, switchedand still would not come up.- Used Fibre as a straight through and still the same.In all cases there was no indication of any life in the connection.It is pointing to a faulty fibre patch lead but I know it has worked in the past. Could it be something to do with the config or device incompatibility? Or any setting I need to activate?

Cisco Switching / Routing :: C3560 - 48PS Port / Get Any Device To Talk To DHCP Server?

Sep 11, 2011

I have a c3560 that on Port 1 I can not get any device to talk to the DHCP server.Previously there was a client connected to this port however over the weekend he stated he lost connectivity.

In my troubleshooting I have connected that client to another port and now he is good to go...I connected my laptop and tried to connect to the network however I could not.I checked the logs and did not see anything that lead me to think it was having problems.

Is there another way to shut this down and hopefully start it back up without having to restart the entire switch?

WS-C3750X-48T-S or WS-C3750X-48T-E will be used.
  
The question is: Will the new SKU works together in a stack with the old ones?  Will there be no changes on the type of stacking cable to be used?
