I need to support a bunch of security cameras mounted on poles in our parking lot and an IP intercom system mounted on some gates. Because of environmental factors the switches at the poles need to be hardened and the spec from the vendor installing the gear is for GarretCom Industrial unmanaged switches which would make sense.
However when Information Security got wind of this scheme they (probably correctly) are requiring me to secure the ports that these unmanaged switches connect to. I have 2 choices: port security w/ MAC filtering or 802.1x. Because all the devices at the poles and gates support 802.1x and because I may need to go out there to troubleshoot stuff (and will invariably forget to add the MAC of whatever device I am using) I would prefer 802.1X multi-auth mode.
Problem:
When I ran a quick test on a test 3560 running some 15.0.1 code I could get a laptop to connect via 802.1x EAP-TLS successfully if it was directly connected but when I connected the same laptop via a dumb Netgear switch I confiscated from a luser it would not connect. The 3560 error said that the laptop never responded.
Question:
Before I spend a whole lot of time on this, is this something that should work? I don't see any practical use for the feature if it won't however the documentation I am using specifically mentions downstream hubs but I am not sure if they mean real hubs (which I don't think are even made anymore) or if they mean unmanaged switches.
I plan to try a couple of different unmanaged switches tomorrow and digg a little but I would like to know if I am wasting my time on something that will never work or if there is a little gotcha somewhere.
I have a 5K with 5 downstream 3560's. I now have a new 5k that I would like to add to the existing 5K as a HA peer. What is the best way to accomplish this with the least amount of downtime for the downstream switches.On the 3560's, i plan setting up port-channels once HA is setup on the 5k's.
I am experiencing a problem on a Catalyst 4510 (cat4500-ipbasek9-mz.122-53.SG.bin) with 802.1x configured. Client PCs are connected via a mini desktop switch to a Cat 4510 switched port in multi-auth mode. The configuration of the port follows:
!interface GigabitEthernet2/34 switchport mode access ip arp inspection limit rate 30 authentication host-mode multi-auth authentication port-control auto authentication periodic authentication timer reauthenticate server dot1x pae authenticator dot1x timeout tx-period 5 dot1x max-reauth-req 6 spanning-tree portfast ip verify source vlan dhcp-snoopingend
It happens from time to time that the Cat 4510 port stops passing traffic. Reconnecting the mini switch recovers the communication. Client PCs connected to the mini switch seem to be authorized at the moment when the problem occures. The RADIUS Termination-Action attribute is set to RADIUS-Request. The problem is not present if "authentication periodic" is disabled.
I am doing an small project, I have to connect 4 cisco switches SF 302-08 (1 GBIC each one) to a core switch SGE 2000 (4 GBICs). Because of cable length I have go connect all 5 switches with fiber. The fiber termination is multimode LC duplex. My confusion is on the mini GBICs. There is compatibilities issues i been reading. [code]
I have a new building to add to our campus and I have been encouraged to run single mode fiber. All of my other buildings are connected with multi-mode fiber. I just want to make sure i will not have an issue if I run single mode to the new building with SM SFP's.
I have L3 switch 3560 v2 cisco switch. If i connect the switch via the console cable in XP system i am not getting any responce. I think i need to install via XY mode.
how can i install the ISO iamge via XY mode in cisco switch 3560 v2.Cisco Model: WS-C3560v2-48tS-S.
Is it possible to have ether-channel across 2 switches? As an example, having a server with 2 ports connect, 1 port to Switch-A and the other to Switch-B and then use those two links on the sepatate switches but to the same server to form an Etherchannel.
I got an ASA 5510 system currently in single context mode, with CSC SSM installed. Single ISP uplink to internet, no VPN. And now customer would like add another ISP uplink, without invest another box for HA.What come across my mind is make the current box into multi context. There's some area i need to concern and also need yours perspective on it.
Question 1: For making the firewall into multi context, am i need to do it from scratch, issue mode multiple command. Then rebuilt the current production config into one of the context, then another context meant for the new IPS uplink, and one admin context?
Question 2: For CSC -SSM licensing requirement, model ASA 5510 with security plus license is able to support 2 context. So if i split my firewall like what i mention in question, what exactly number of context do i own (admin, context A, context B)?
Question 3: For CSC-SSM module in multi context mode, so the management port of CSC SSM must attach at admin context?
Question 4: After configured all the policy and traffic to scan, how exactly i should do in order apply this policy to the interface? Should i only enable at admin context, then firewall service-policy rules, and apply it global, OR should i also do the same action on context A and Context B?
Was building a small network in Cisco Packet Tracer and ran in to an issue. I have 4 routers running OSPF, and off one of the routers I have 5 3560 Multilayer switches. The router that the switches hang off of, I have a sub-interface with dot1q encapsulation, set for vlan 10 and an IP Address. 10.14.16.1/24. The switches have interface vlan 10 configures, and have IPs in the same subnet. From that router, I can ping/telnet to all the switches without issue. My problem arises when I try and reach those switches from any other router. OSPF is set to redistribute static and connected subnets.The routing table is populated correctly on all the routers. When I ping and trace the packet, it looks like it makes it all the way to the respective switch, but the packet never makes it back. I've played with the default route on the switches to no avail. Am I trying to implement this incorrectly, or am I just missing something?
whether VSS technology support on 3560 switches.I'm planning to intergrate new Cisco 2x6509 with VSS and all the access swtiches 3560's uplink to core 6509..if not support, what will be the solution or any bug fixing or new IOS releasing
In cisco documentation for the 3560 it is mentioned that blocking appletalk will not work .It shows up in command line but it is not working due to hardware limitation.Is there any other way to block appletalk on 3560 swiitches.
I have a question about RSPAN, is this feature only supported on 6500 and 4500 switchs?
we have 2 3560 switches and want to use RSPAN to monitor different source ports.I checked thorugh the cisco feature navigator and the IOS we have on 3560 has the RSPAN fature listed in them.
We have several DMVPN-connected sites that are connected to our 2821 ISR pair.They're all configured as eigrp stub connected summary. Yesterday, a few of the sites went inaccessible, but the VPN tunnels were still up and running. Upon further investigation, we noticed that the remote sites stopped receiving routing updates from our 2821's. As a quick fix, we added static routes to bring the sites back up.Later that night, we removed the static routes and cleared the eigrp neighbors, hoping it would fix the problem. When it didn't, we cleared them two more times.Suddenly, the router lost all downstream adjacencies. While we were adding statics to at least bring the sites back up, all of the adjacencies came back.
OSPF normally only comes with IPservices image and not IP Base image. The 3560-C series data sheet says that it only suport IP Base image, yet it mentions that support for OSPF in included. Are there any restictions in the OSPF support?.
We have 7 3560's in 7 different locations connected to our providor for wan access. Our provider has given us a copper cable at each point and we have connected it directly to our 3560 switch at each location. Each port is configured the same way at each location. Each switch is running eigrp.All of the switch ports on each switch are configured as a trunk and vlan 299 had the ip address for the eigrp connection: [code] This setup is working as each switch see's all of the other switches as an eigrp neighbor. We have also made sure that the switch at our head office has spanning tree priority for vlan 299.
So the problem is, if there is a change in the topology at one of the locations it usually causes one or more of the other connections to go down for some reason. We just cannot pinpoint what is causing this change. There are no log's or anything other than an eigrp hold time expired message.?
We have a couple of Cisco switches and connected a (Windows 7) laptop to one of them and it gets its IP address from a DHCP server.I can now ping the IP from all of the switches, no problem, also not when I log on to the core switch in the same VLAN as both notebooks. But from my (Windows 7) laptop, which is in the same VLAN as the target laptop, I cannot ping it.
I checked, default gateway is good on both sides, as are DNS servers.
For some special arrangement, I would like to connect 2 access ports from a 3550 switch to 3560 switch.1 port for vlan 200, another port for vlan 201.Will this introduce bad thing to the switches?
I have a Cisco 3560 connected via fiber to a Nortel 1612G. The connection is up/up, the V LAN's on the switch work as needed, but I can not ping the switch from the Nortel, and as a result I can not remote into the Cisco for management. I see in the configuration for the trunk that it is configured for a native v LAN, but I don't see it defined which v LAN's are allowed, could this be the issue? I will provide some of the config information for the Cisco side, I understand the issue may be on the Nortel end but if the Cisco part looks OK?
Port config for the trunk:
interface GigabitEthernet0/49 description port_6_1612G switch port trunk encapsulation dot1q switch port trunk native v LAN 120 switch port mode trunk
I have a connection between switches, There are a 3560 (Gi0/37) and a 2960 (Gi0/1), the problem is in the port Gi0/37 of the 3560 switch and this is the log. [code]
I dont understand what is the problem, actually i have added the command power inline never on the port and the problem is solved, but we haven´t changed configuration.
We have two Cisco switches with one 3560 and one 3750 we have created a new Vlan 4 with IP 10.1.3.x 255.255.255.0 - no shut then assigne to gi 2/0/46 on the 3560 Vlan 4 ip address 10.1.3.x 255.255.255.0 no shut then assign to FA0/45. All interfaces are up up along with the Vlan up up, we can ping the local IP address bu not able to pint the other switch.
We are in the process of rolling out iPads to our offices. As part of this implementation, we need to print from the iPads to our network printers. Our network printers are mostly HP and Xerox and do not have native Apple AirPrint capabilities. As such, we have been using the FingerPrint software to share out the network printers as Apple AirPrint printers. We have a mixture of switches at our offices. Most offices utilize a 3550 PoE switch. In these offices the AirPrint traffic is being transferred successfully and everything works great. In the offices which are using 3560 PoE switches, the traffic is never seen at the iPads. We are using EnGenius EAP300 access points connected into the Cisco switches to provide wireless access to the iPads. Both 3550 and 3560 switches are running iOS 12.2(25). What might be stopping/blocking the AirPrint traffic on the 3560 switches?
I have a couple of 3560 switches running c3560-advipservicesk9-mz.122-44 and they are randomly experiencing the following:
- The switch locks up with no preceding error message in the log (I am forwarding syslog to Splunk).
- Upon reboot, the switch goes through the normal startup sequence with no error messages, then for some reason reloads the flash and starts all over again. (refer to doc)
This could happen after days or weeks. Sometimes they will go through two of these reloads on boot and be fine for awhile, and other times they will be stuck in the loop infinitely. I am using this same image with all of our 3560s, but am only having this issue with two of them.
I have 3 3560 switches which are configured with trunks between them. They run vlan 10, 11 & 12. I have a 'core' switch (switch 1) of these 3 to which an MPLS router is connected on vlan12. I in addition have another switch hanging off the 'core' switch via a routed link (switch 4). I have EIGRP configured as a stub and as such the IP address on the routed link at the core switch end is of a /24 from v lan 1 on the other switch. This makes the route directly connected and therefore distributed via EIGRP stubs. Switch 1 is then exchanging routes with the MPLS router (via EIGRP).
The problem I have is that from any sub net on any switch (switch 1, 2 or 3) I can ping 192.168.13.1 (switch 4). When I try and ping switch 4 from over the MPLS I am unable to. If I trace to the switch I see it reaches the outside of the MPLS router, but is then unresponsive. The same applies if I try to ping switch 1 on 192.168.13.2. Any of the other IP addresses of switch 1 respond.
The MPLS network is a managed solution to which I have no access. I'm told that the MPLS provider is able to ping switch 1 & switch 4 on the 192.168.13.x addresses from a remote router (192.168.32.2). I have tried from a switch on the same L2 sub net (192.168.32.1) and I don't get a response.
From switch 4 I am able to ping the switch on 1 of it's interfaces (192.168.19.1), but not the interface I mentioned above 192.168.32.1. There are no access lists in place on the switches and no firewalls between the sites.
I have 3560's in my current environment, operating in the core/distro/access layers. The switches are in a star configuration, performs only layer 2 switching, and utilizes copper (no plans on moving to fiber).
With a fairly limited budget, I've been contemplating on upgrading the central node to a stacked 3750X to eliminate that single point of failure, and trunk the rest of the 3560's to the stacked switch. I wanted to be sure that the 3750X switches will be right for my environment (90-100 hosts), and if what I explained above is a good solution.
I'm also looking like to upgrade 6-7 of my servers (and SAN) with 10GB network cards. Do the ports on the 3750X have port densities capable of 10GB? If not, what switches provide that capability?
Does a portable RPS device either from Cisco or another manufacturer exists, that would allow you to move primary power for a switch without causing an outage? I realize that for the Catalyst 3560 for example, you can get an RPS 2300 or 675, but my understanding is that these are made for a more permanent installation, not to mention rather costly.
It looks like the RPS 675 is rather inexpensive after all, especially in the secondary market, but still rather large for toting around.
I've been fighting what seems to be an increased number of outqueue drops on our core stack and edge switches for the last 3 or 4 weeks.(The core consists of a stack of 5 3750s in 32-gig stack mode. The wkgrp switches are 3560s. all are at 12.2.52) The wkgrp switches are directly connected to users. We use Nortel IP phones with the phone inline with the user PC. auto-neg to 100/full. [code] However I have tried turning off QOS on a couple of workgroup switches (no mls qos, but left individual port configurations the same) but am still seeing drops.Since I have disabled qos on the switches in question (no mls qos) (not the core tho) I am presuming these commands have no affect on the switch operation and therefore cannot be related to the problem. With QOS turned off one would presume that it is general congestion - especially at the user edge where busy PC issues might contribute. So I wanted to see if I could see any instances of packets in the output queues building up.
I wrote some scripts and macros that essentially did a snapshot of 'show int' every 20 seconds or so, and looked for instances of 'Queue: x/' where x was greater than zero.What I found after several days of watching the core stack, and a few of the workgroup switches that are most often displaying the behavior, was that I NEVER saw ANY packets in output queues. I often saw packets in Input queues for VLAN1, once in a great while I would see packets on input queues for fa or Gi interfaces, but NEVER on output queues. [ code] Additionally, when I look (via snmp) at interface utilization on interfaces showing queue drops (both core and wkgroup), they are occurring at ridiculously low utilization levels (as low as 4 to 8%). I've tried to look for microbursts between the core and a wkgroup switch where the core interface was experiencing drops, but haven't seen any (using observer suite). [code] While the queue-drop counts aren't critically high at this point, they are happening more frequently than in the past and I would like to understand what is going on... In most cases, no error counters are incrementing for these interfaces. Is there some mechanism besides congestion that could cause output queue drops?
I have a stack of 8 3750x switches connected via Stackwise. In addition, I have these switches configured as two Powerstacks. When I look at the Powerstacks, they are showing as being in power-sharing mode. When I look at the individual switches, they show as standalone. Right now, I have 1 switch in each powerstack that has two power supplies, and then the other three have a single power supply. Below is the output for "Show stack-power detail" as well as the Powerstack configurations.

I'm looking for switches that support single mode fiber connections and would like to know if "WS-C3750-FS-S Catalyst 3750 24 100BaseFX + 2 SFP" and "WS-C3750G-12S-S Catalyst 3750 12 SFP" can serve the purpose?
I faced with a strange behavior of ME3600.For testing purposes I linked Cat3550 and ME3600 switches via trunk mode. All interfaces are in Up state. But I couldn't ping SVI200 of Cat switch from ME3600 and vice versa. [cde]
This scheme perfectly works with another L3 swithes. For example Catalist3750. I know that ME doesn't support VTP, DTP and so on. Also, I've tried latest software.
I am troubleshooting a fiber connectivity issue.Now I have two switches, one is 3750, and another is small biz 300 series switch. Both switch has a single mode smf gbic. Now I have two swtiches face to face and connect with a single mode cable. Do you think if I would get a link light on? Both ports are no shutdown.
