Cisco Infrastructure :: 3560x Switches Died After Working Normally
Dec 5, 2012
We just got many 3560x switches for a project. Curiously and in a very rate event (at least for me ) 4 of them died after workijg normally. 3 for some days and the last one for 3 weeks.Power supplies are ok and light up, they work on other switches, fans dont start kn the damagdd switch but work in ither switches.Syslog server doesnt show anything. It just goes puff. They are brand new switches biught one month ago from official channek distributor.

I applied command "auto qos voip trust" to the uplink interface. But I found that the interface shown command "auto qos trust" was applied when i show running-config. Could the command "auto qos voip trust" show in the configuration after i applied? If not, how can i check the interface that applied "auto qos voip trust"?

I am trying to connect tow 3560X using a fiber cable (MM)I have C3KX-NM-10G in both switches (4 ports module)I have GLC-SX-MM in both switches (connected to G1/1)both switches are able to see & recognize the NM as well as the SFP.
Fiber Cable is tested Fiber Patch Cord also tested both ports configured as a trunks but also the switches are not able to see each other (even when I removed the trunks configuration from both of them)CDP neibour is showing nothing no links & no LED blink in any switch both switches are running c3560e-universalk9-mz.122-55.SE3 IOS?
There is no any other configuration in both switches.

In one of my client location I have deployed one Cisco 3560X (core switch) and one SG-200-18 (access switch). I’ve configured three vlans (vlan 2, vlan 3 and management vlan 1), relevant trunking and I’ve connected two pc to the access switch to vlan 2 and 3 respectively. So far everything (including inter-vlan communication) works fine, except that I couldn’t reach the vlan 1 (management vlan) devices (access switch and core switch) from any pc which is connected to either vlan 2 or 3.
I’ve configured the “port VLAN membership” settings in SG-300 as follows,
Interface mode Administrative vlans Operational vlans
GE 2 Access 2UP
[Code].....

We recently upgraded the switch to which an old security device was connected. It worked fine on the old switch's FastEthernet port, which was configured for speed 10 and duplex half, as that is what the device required. The new switch is a 3560X with all Gigabit ports, but the security device's port, also configured with speed 10 and duplex half, does not connect properly.As a temporary test, we daisychained another switch that has FastEthernet ports, and the security device works again.Is there anything else that needs to be added to the configuration, when using Gigabit ports at 10/half?

We are using 18 numbers of 3560X -Lan base series switches in our network(Access layer). We have 400 users and created vlans in access switches. we are planning to purchase Two numbers of 4900 M as Core layer switch and for redundancy. The uplink would be on 10 gig copper cable (CAT 7) between the access layer switches and core switches. I like to know whether 4900M can take the load of 18 access switches.

I have been with AT&T Uverse at the current place I'm living for almost a month. The connection has been satisfactory for the first three weeks, but this last week my PC's connection has gone diggin through the Earth cause it sure as hell can't penetrate clearly.I personally have three devices, and the two roommates have their own and they have not mentioned any issues with theirs-if they've even noticed.My Devices:PC - OMG FML KMN, Mainly cause I want my EVE (crack)PS3 - No ProblemsTablet - No ProblemsSpeeds have been testing in ranges from 0.09 kbps to 8.25 mbps over five samplings this morning while the tablet's been testing standard speeds consistently.
During Xirrus' "Ping" testing (Yes, I Googled the hell out of and troubleshot this irritation for now almost two days first) my PC's connection died and was unable to locate my connection for at least 30 seconds. This had happened several times yesterday as well with the following instances :EVE Online x 2 clients I lost a thorax cause of itFive peripheral programs: Mumble, Pidgeon, Pyfa, EVEHQ, Garpa At least five tabs open on ChromeMisc software.In the past few days my PC's connection has been highly intermittent-and that's at best. First I thought it has something to do with my video drivers which I updated to no effect. Then I thought it might have something to do with some of the software I use for EVE Online which had me trying variations of running programs to still no useful effect.
I've also switched from the internal wireless device to a NetGear Dual Band adapter, but unfortunately it still produces the same results. This put me at a loss. If my other devices are staying connected, but two independent network devices produced the same failing result on the same PC...wth maaaan. Software? Hardware?

after an upgrade of NCS 1.1.1.24 to CPI 1.2 on green field, it was not possible to reuse the GUI. During the upgrade, I''ve shortly seen an oracle DB error, but the upgrade was going through, without problems.At the end, it was not possible to use the GUI, and every trial to start the services was stopped with errors.I've found the following severe Bug ID's in the support forum: Bug CSCuc29378 Prime Infrastructure 1.2 won't start after a db restore/Upgrade from NCS1.1.1.24 Oracle DB bug as well: CSCtw59460.I see only a new installation from scratch (1.2) as solution, but the bug is not resolved in V1.2, as seen in the bug tool.
- As the customer has an v.1.0 license who worked with NCS 1.1.1, do I need an upgrade order to be able to activate an installation from the v 1.2 ova (new PAK)??
- I'm searching for a one year CPI partner license, because I heard about in some Cisco Live sessions, but I did not find a way to acces´s to it.

We have a 6509 running 5.4(2). We have set up a hyperterm session and connect to multiple devices, then we get to the 6509 and it will not work. When we reload the 6509 and we are consoled into it, we get data until it is finished reloading. Then the console connections is no longer there.

Steps to repeat the bug:
1) Physical Reset of SR520-FE to factory defaults
2) Run CCA 3.1(1) and connect to 192.168.75.1 using the default cisco/cisco login
3) Under the Home Menu, click the Device Setup Wizard
4) In Step 1, sellect the SR520 and observe that there is also a photograph of the SR520-FE(W) model displayed as feedback for Step 1
5) Try variations of Steps 2 through 4
Note: Step 4 has a problem because it says to plug the power into the device, but if the power was not already plugged in to begin with, we could not run the Device Setup Wizard in the first place.
6) Step 5 prompts for a user name and password.
BUG: No permutations of the documented default usernames and passwords "cisco" or "admin" work. The result is always the error dialog:Device Connectivity Status - "Failure: Not Connected.""Return to Step 1. Make sure that your PC is not connected to a network and you follow all the instructions."A search of the web indicates others are also had this unresolved issue with previous CCA releases.

A customer is expanding their network into another wing, and they have a good number of existing Small Business switches (specifically the SGE-2010P - [URL] that they're interested in possibly deploying. They have a full-blown Cisco infrastructure and voice deployment (Cat 6500 core switches, 3750 switch stacks, Communications Manager w/ over 1,000 phones, etc.).
The general concern is whether there is ANY known issues or concerns with trying to mix/integrate the Small Business equipment with non-SMB infrastructure. Looking at the datasheet for this switch, it's clearly PoE, supports QoS, although it doesn't specifically indicate it can provide a voice/auxiliary VLAN for a phone detected by CDP - that would be a big deal. So basically, "a switch is a switch", and I'm just posing this question to make sure there's no reason (technically or from a support standpoint) that we would not recommend integrating these.

WS-C2960G-24TC-L 12.2(25)SEE3 C2960-LANBASE-M
I would like to get the temperature status from this 2960 switch (and several other models. Normally this OID should be:.1.3.6.1.4.1.9.9.13.1.3.1.6 But it does not return anything.
The termperature status can be found from the command line by running:"sh env temp" This reports back ok, so I assume there is a temperate gauge in the switch.
This oid is part of the "CISCO-ENVMON-MIB" mib and accouding to the Cisco MIB selector it is supported on my switch and IOS - 12.2(25).
(Another thing I woudl like to monitor and should be supported is the fan status oid (.1.3.6.1.4.1.9.9.13.1.4.1.3). That doesn't return anything either.
What do I need to do to get the temperature environment status from SNMP query?

We were unable to login to a 3825 with a known good password, so we used Cisco's Password Recovery Procedure for that device. We were successful in resetting the password, and had access to the CLI. However, when we logged out of the router, then attempted to log back in, the 'Invalid Password' prompt again came up.We have to use password recovery each and every time we need to access the CLI. Might this be an NVRAM problem?
Show version for this device is: C3825-advsecurityk9-m 12.4(3a).

I am trying to test (if possible) the idea of having 2 6509-E switches connected directly to each other while using VRF-lite (Sup 2T). The idea is to have 3-4 separate networks. For example Net-A, Net-B,Net-C, Net-D. There is no PE router*, just these two switches. Also, there sin't any other access layer switches. All users connect directly to the 6509-E's via switch 48 port switch blades.
Net-A and Net-B on separate VRF's, but able to talk to each other. Net-C and Net-D* on separate VRF's without being able to talk to any other. Net-D* will have a PE since it comes from an external network. This is something I would like to test in a lab environment, but I am not familiar with VRF's.

I have a 100mbps internet connection from my ISP but once the connection hits the ASA the download speed gets reduced to 15mbps. My network is setup as follows: ISP Modem ---- Edge Switch ----- ASA --- Internal Cisco Switches
If I plug my computer into an extra port on the Edge Switch I get speeds around 92mbps with normal traffic still going to the ASA. But when I plug into the ASA and internal switches I have speeds of 15mbps.
I have made sure that duplex/speed match on the links. I have done packet captures and within two minutes I do have several dup acks and retransmissions. The retransmissions don't seem to match the dup acks. (The retransmission is not for the dup ack requested so the dup ack keeps being resent)
The only interface error is on the inside interface which includes 700 overruns in a weeks worth of time.I am not using an IPS/IDS. I do have several vpns on it but was not going through a vpn tunnel. I am also using NAT.I am using an ASA 5510 8.2(1)

I'm working for KOREA TELECOM, and currently providing MPLS VPN.We're planning to provide our customer with traffic report using NetFlow..
I read some documents which reads Netflow ver.9 can be enabled on Cisco GSR 12000 Series, but no mention about catalyst switches. Netflow ver 9 can be activated on catalyst 6500 series.. because the point where switch is located already have mpls encapsulated packet ( mpls vpn packet).

I want to connect a 6911 IP Phone to a SG 300 switch. This is my scenario: vlan 3 data, vlan 9 voice, vlan 10 admin.I have a trunk on port 10 of the SG 300 (vlan 1 untagged, vlan 3,9,10 tagged) and it is connected to a switch 3560, this switch has all the L3 configuration of the vlans and the SG 300 switch has an IP on the admin vlan (10).Also i added the OUI of my IP phones an created an LLDP Policy. Right now I have a 7941 IP Phone working but 6911 is not working. Iam using the new version 1.1.0.73 that supports CDP.
Also I noticed that even when my PC and IP phone receive IP address they can not ping each other nor the SG 300. They only can ping the default gateway or IP addresses in diferent vlans but connected on 3560 switch.

We just purchased 8 managed switches POE to swap out our existing in preparation for our new phone system. We installed them all after configuring with static IP. Deployed... and all but two work fine. Any tips for troubleshooting why two of them do not work? There are a couple other switches in the building. Could it be that a switch "upstream" from the two non-functioning switches is causing an issue? If so, how do I find out? When we put back the two "dumb" switches all was fine.

We have two Web Servers and configured as Network Load Balancing in a cluster for failover.
WEB1 IP: 192.168.1.50
WEB2 IP: 192.168.1.51
Both configured with Cluster IP: 192.168.1.100 on Multicast mode.
TEST ON LAB USING ORDINARY 10/100 UNMANAGED SWITCH I can ping all the IP addresses on the LAN and when I http://192.168.1.110 on any PC on the LAN works no problem.
TEST ON PRODUCTION USING CISCO SG200 50/50 PORT SWITCH I can ping all the IP addresse on the LAN and when I http://192.168.1.110 on a different machine i did not work, but on the server itself will work as expected.
NOTE: Both tests are on LAN only.
I wonder if this is something to do with the switch because of Cluster IP MAC address. Do I need to configure something on the switch?

We have a single SGE2010 in layer 3 mode switch with a Server 2008 DHCP server.
We will be implimenting a Voip netowork where the PC's connect to the voip phone. I would like to create another vlan - 10. I have created the vlan and assigned the IP on the swtich.
Routing seems to be working. I can ping both IP addresses of the switch on either vlan.
I cannot get DHCP working. In the SGE switch I have enabled DHCP Relay, enabled option 82, set my DHCP Interface as VLan1, and specified the DHCP servers IP address. On the ports I have set the port where the DHCP server connects to as a trunk port with Vlan 1 untagged and vlan 10 tagged. I have set the ports where the phones connect as a trunk port with vlan1 untagged and vlan 10 tagged.
