Cisco Switching/Routing :: Catalyst 3560-X IOS 15.0(2) IP Base?
Nov 29, 2012
We have observed increase of CPU utilization of 50% after upgrade from 15.0(1)SE3 to 15.0(2).The SDM template is "desktop default" template.The increase of CPU utilization in Switches with LAN Base after upgrade is about 10%.
How to find the cause for the 50% increase ?This is command is the output of 15.0(2). The calculated sum for 5min process-utilization is 21% plus 1% interrupt is 22 %. Where is the rest ?
switch#sh proc cpu sorted 5min | exc 0.00
CPU utilization for five seconds: 30%/1%; one minute: 29%; five minutes: 28%

I'm currently configuring per port policing on a 3560 and want to limit inbound traffic to 750mbit:
mls qos access-list 1 permit any class SET_IF match access-group 1 policy-map SET_QOS class SET_IF
When I test the setup with iperf I always get different results when I change the nummber of parallel connections.Isn't there a way to limit the throughput regardless of the number of conns (INGRESS!) like with srr-queue bandwith limit?
I have a 2504 WLC connected to a Catalyst 3560 which has multiple vlans and is connected to a 2800 series router. I know the catalyst is L3 but I am needing nat functions to get outside to the internet. From my 2800 series router I am able to ping out to the internet, also I am able to ping the vlan interfaces on the catalyst switch. Problem is from the catalyst switch I can ping the inside and outside address of the 2800 but I cannot get any further then that. I cannot ping the 2800 router gateway. Not sure what I am doing wrong as far as routing.
The 3560 switch is serving as an access and distribution layer switch. End devices are connected to it and it also implements IP routing via SVI and L3 ports.Auto qos voice cisco-phone has been implemented on applicable access layer ports. SRND4 is being used.
Question 1:Why is the auto qos generated policed-dscp map different on these two switches?The Cisco Smart Business Architecture LAN configuration files guide [URL] does not specifically use the 3560 in their examples, they use the 3750 but it's my assumption that the same techniques, configs apply with regard to my specific feature questions. When using a 3750 in the Access layer, the guide shows (page 15) the same auto qos generated policed-dscp map configuration that is on my 2960. The SBA LAN config guide shows that when using a 3750 as a Distribution layer switch (page 26), the policed-dscp map configuration is the same that I see on my 3560.In the configuration guide for the 3750 distro switch, there is no auto qos applied as there are no access ports, so the mls qos commands are manually input. Since my 3560 does have access ports, auto qos generated the mls qos commands, and the results are the same be it following the guide and manually entering (per distro switch guidelines) or using auto qos. This leads to question 2...
Question 2:Why is the mls qos map policed-dscp configuration different depending on use as an access vs. distribution switch?
Question 3: On the 3560, access ports that have "auto qos voice cisco-phone" applied are put into queue-set 2 (output). Queue-set 2 (output) uses default values (not configured). Is this correct and desirable? If so, why? The 2960 has all ports in queue-set 1, regardless of being an access device port or a trunk port connected to the 3560 (as per the SBA LAN config guide EgressQOS macro commands). The 3560 trunk ports are all also configured to use queue-set 1 (output), again as per the SBA LAN config guide EgressQOS marco commands.
I have one specific trouble with Catalyst 3560CG switch and Stardom reserved industrial controller. Controller has 2 processors, one of them after(!) negotiation become main with IP 192.168.1.1, other one stays in reserve with IP 192.168.1.129. If main one shuts down, spare one becomes main with IP 192.168.1.1. This perfectly works with DLINK and MOXA level 2 switches, but fails with Catalyst 3560, because spare one cannot even connect to switch port. I don't know the exact reason of it, but i suspect, that it happens because of before negotiation both controllers have ip 192.168.1.1 (i know, that it is wrong and weird, but so it goes). First of them correctly connects to switch port, which goes up and passes pings. Second processor tries to connect to switch port, which goes several times up and very soon down, then processor lefts his tries to connect to anybody and become idle. The switch seems to some way check IPs of 1-st and 2-nd port packets, and shuts down 2-nd port. I have connected via hyperterminal and tried to disable some level 3 functions and checks of the switch, but this wasn't useful. how exactly(or at least approximately) should i configure a switch to make this bundle work?
I've just installed 2 of these in my workplace on a PLC network.I'm now looking to set one of the ports up as my diagnostic port and would like to be able to mirror any of the other ports to this port.I believe it is called SPAN on Cisco switches.The only reference I can find to it is configuring via Telnet which I haven't got a clue about.On my old Wiedmuller switches it was just a few clicks away.
Scenario: Two buildings connected with a private leased fiber line, so it does operate as a LAN. There are several subnets and everyone at both buildings needs to be able to access all subnets. However the physical machines on those subnets are building specific:
The majority of the traffic between the subnets is specific to the buildings as well (i.e. most of the traffic is between 10.1 and 10.3 or 10.2 and 10.4).
Currently I have a Catalyst 3560 at Building 1 operating as the single "core" L3 router (and then a variety of switches connected to that). I have another 3560 at Building 2 that I'd like to turn in to the "master" L3 router for the two subnets primarily used by Building 2. In other words, make it so traffic from 10.1 to 10.3 doesn't have to run to building 1 just to get back to building 2.
I've got a basic knowledge of adding VLANs, VLAN interfaces and a static routes. The part that I'm getting confused on is that the Building 1 core router needs to make its default route to the firewall (and on to the internet) but "know" that traffic on vlans 10 and 30 gets sent across the fiber line to the other router. So I'm assuming this gets done with some combination of vlan definitions, vlan interfaces and static ip routes on each router.
2. there are multiple mobile sets of equipment(servers and catalyst 3560 switch) which i need to connect at different sites. (i cant use repeated subnets)
3. i cant change the ip address/subnets/configuration of the servers and switch, when deploying at different sites. (big problem to me)
i was previously looking at IP unnumbered + OSPF to apply on the mobile sets of equipment. but noticed that IP unnumbered on non pt-to-pt interfaces (which happens to be a 3560) does not work with dynamic protocols. is there any solutions/alternatives which i can achive mobility on equipment?
I am currently deciding which IOS to use for various catalyst 3560 models. Version 12.2(55)SE3 seems fitting for this case, but I cant find out when the 12.2SE reaches End of Software Maintenance. I have checked this link: urls...
I just recieved a new 3560-x switch with the C3KX-PWR-715WAC. It looks like Cisco is now using a different AC power cable. Not the StackPower connector, but the standard AC power cable. My data center is setup to supply 208v using C13 power cables. The switch uses a C15 power cable, and comes with a standard NEMA 5 to C13 power cable. Does Cisco make, or officially support a C13 to C15 power cable? Can I still use a 208v power supply with these switches? I'm using an APC AP8861 power distribution unit, see [URL]
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.
I'm configuring two etherchannel groups (2 ports in each) on a 3560 switch. I need to trunk multiple vlans over each channel group.
I created the vlan trunks and allowed vlans on each physical interface. I notice that I can also configure the vlan trunks on the port-channel interfaces that were created. Should I configure them under those interfaces, or leave them on the physical interfaces? Relevant config is below:
I'm attempting to configure a Catalyst 3560-X Switch to act as a DHCP Server. There is documentation that supports this feature. Below is my config procedure however after the completed procedue no IPs are handed out to clients. [code]
We have quite a few 3560 & 2960 on our edge network - what I have been looking at was to access switches via web-interface i.e. web-browser. Only problem with this is it always gives you access on privilige level 15 which is not ideal as not all who we decide to give access to these switches will be admin and allowed to configure these swicthes - In the 3560/2960 data-sheet states:
"Alternatively, a local username and password database can be configured on the switch itself. Fifteen levels of authorization on the switch console and two levels on the Web-based management interface provide the ability to give different levels of configuration capabilities to different administrators"
Where as there is no mention of how to configure these two levels of Web-based management in the configuration guide.
Im trying to access the switch to reset the password to factory defaults (please see switch output Astrix has removed customer identifying information for security purposes.) Each time I reboot the switch and try and access the password recover mode this same output below starts and im still not able to access the recovery area of the switch

I have some Ethernet-connected cameras that all have the same Ethernet MAC address FF:FF:FF:0A:0A:0A. They were originally designed to directly connect to a Windows PC, but they can also connect through a simple unmanaged switch.A Catalyst 3560 switch won't forward packets to or from anything with that MAC address, at least not by default. Is there a way to convince the switch to do so?
It was my hope to replace the dedicated connections we have for these cameras with a separate VLAN for each camera, and switch them through our existing switch network. Given that all of the cameras use the same MAC address, putting them on the same network is out of the question, but different VLANs, where the only two devices on each VLAN were the camera and the PC that uses it, would be fine.
The switches run IOS 12.2(55) SE through SE3. I learned the camera MAC address from the PC's ARP table while the camera software runs; it turns out the cameras don't have a full IP stack either and don't even do ICMP.
A check out a network segment and want to know why SwA has a static route to SwB if SwA already has a Default GW to Core?
(SwA, SwB - Catalyst3560, Core - Catalyst4948)Note, there are distribute list on SwA - it does not has any OSPF route (exclude O*IA).
Does this mean when SwA send out packet with DA 10.5.64.0/26, Core will use only L2 switching (instead of L3)? Is this more effectively for Core Switch?
Pleace check my reasoning: 1. When use a static route: SwA receive packet from Vlan 20 with DA 10.5.64.0/26 it will strip out Dest. MAC and replace it with MAC of SwB. Core will switch this packet to SwB based on mac add. table (l2 switching)
2. When SwA has only Default gateway and receive packet from Vlan20 with DA 10.5.64.0/26 it replace Dest. MAC with Core MAC. Core receive this packet, lookup route table for 10.5.64.0 entry and forward packet base on this.
