1142N NON_CISCO-NO_CDP_RECEIVED with 3560 switch
I thought the 3560 switches, the 8 port and 24 port are 802.3af standard switches? When I connect 1142N radios to them I get the no cdp error and the radios are disabled. I have 17 of these that I converted to LAP, and I got the issue both before and after upgrading to LAP from AP. It's not like I disabled CDP on the switches.
I may have found the problem. I thought I had initially connected to a switchport that was just setup as a switchport access vlan, with no other configurations on it, and after looking at the port found it was a trunk port, which should work, and does for the other AP's I worked with, but not the 1142N.
I took one of the other AP's that is connected to the test switch I am using to setup the WLC and AP's and connected that to one of the unconfigured ports, with default settings and the radios both powered up and I saw CDP neighbor detail,
I removed spanning-tree portfast from the trunk port, and reconnected the AP to that port, I saw it negotiated full power, but I dont see neighbor information. I had to console in and do a no shut on dot11radio 0 for it to come up on all 3 of them.
I went back and pulled that new one out of the box and reconnected to the interface I used before after removing portfast, still had the same problem, then removed the trunk configuration, and rebooted. Now I see
*Mar 1 00:14:19.266: %CDP_PD-2-POWER_LOW: All radios disabled - NEGOTIATED WS-C3560-8PC
Fa0/6 auto on 14.5 AIR-LAP1142N-A-K9 3 15.4
I took one of the other AP's that I boxed up and connected it to the same port, this was a converted AP to LAP.
Fa0/6 auto on 15.4 AIR-LAP1142N-A-K9 3 15.4
Futher puzzlement, plugged that last AP into the test switch which is setup to mimic a remote location with trunk ports for FlexConnect, and after the radio powered up, and joined the controller, saw this.

Why would radio 0 be admin down? It is enabled on the WLC. I went into the AP and did a no shut on it too. Not sure what is going on with this, never ran into this sort of issue before.

Intel MAC Compatibility with 3560/Other Catalyst Switches
Some of our users recently reported problems with their new Intel based Macintosh computers when we upgraded from old Extreme Summits to Catalyst 3560 series switches. They report sluggish response from the network. We have checked the ports for negotiation issues and errors and do not find any. Suspect the Intel Mac; but wanted to find out if anyone else is experiencing the same or has suggestions. Thanks.
Hello,
to my understanding MAC issues should not be the cause of your issues. Either the Ethernet frame is standard compliant, then there should not be an issue with Catalyst switches and no port errors. Or the Ethernet frames or MAC in use is non standard then the switch would report an error.
Network response times depend on many things and negotiation might be the first thing to check - as you did. I would still recommend fixed settings for port speed and especially duplex. Just to avoid also intermittend problems (f.e. between PC reboots).
Have you also checked for MTU and TCP window size settings? What else did change when you upgraded to the 3560s? Did you also check Router and switch ports for duplex and speed settings?
Hope this helps! Please rate all posts.

Embeded Event Manager on cisco 3560 switch
Can someone help me please? I have EEM configured on cisco 3560 switch. The configuration is below. I want that switch inform me through email when device with particilular IP address become unavailable. For some reason this configuration is not good and I can't tell why. I already try to debug this with debug event manager action mail but didn't see any output .
ip sla 11
icmp-echo ip address

ip sla schedule 11 life forever start-time now

action 02.0 mail server "ip address" to "[email protected]" from "[email protected]" subject "device is down"The mail part looks good, I'm not sure you are hitting the trigger right.
Why not do a track on the ip sla instead of the snmp stuff?
Here's a good example of that.

The trunk ports are working just fine. I have configured all necessary remote management with no issues. However, my access ports are not working. I have set them up exactly the same as the adjacent switch A and it works just fine, but the same configuration on the new switch has not been able to pull IP information. I have provided information as to how the switch access ports are configured on both Switch A (working) and Switch B (not working). I should note that I tried this with a Cisco 7940 phone and it got stuck on "configuring IP" then I tried it with my laptop and it pulled a 169 IP address. Both were direct connections into switch B. When I run a show mac-address-table, neither device shows up in the table. Only the gig port MACs. Any thoughts? Please let me know if you need any more information.

It looks like you're guiding me in the right direction. I did a "show port security interface fa0/2" on the new switch and nothing was out of the ordinary with the exception of the 0 MAC addresses learned. But then I did a "show spanning tree vlan 224" Here's what I found:

AAA and 3560 Switch + CNA
Hi
Has anyone got this to work?
CNA. (Cisco Networks Assistants) and AAA (Tacacs+) on a 3560 switch.
I cant get the CNA to work in this setup but it works fine on together with 3500XL and 3550 serie switch. With the same parameter.
this is the aaa conf.
aaa authentication login default group tacacs+ local
aaa authentication login no_tacacs enable
aaa authentication enable default enable group tacacs+ none
aaa authorization exec default group tacacs+ local
aaa authorization exec no_tacacs none
aaa authorization commands 15 default group tacacs+ if-authenticated local

aaa accounting commands 15 default start-stop group tacacs+
aaa accounting network default start-stop group tacacs+
ip http server
ip http authentication aaaHi
No. I get the prompt for username and password.
and hit enter. Then nothing happens. It looks like it's trying to build the network but it never get fines. I know it works without the aaa statement. But I cant live with that. -
Cisco 3560 switch| mls qos trust dscp question
Hi everybody
Hi everybody .
Please consider the following example:
3560 sw f1/1--------trunk---SW2
3560 sw
f1/1
mls qos trust dscp
3560 is using default cos-dscp map, assume a 3560 receives a frame carrying IP packet on f1/1 with COS 4, what will 3560 switch do?
1) will it use its default cos --dscp map ( cos 4--.dscp 32) and rewrite 32 in dscp field of the packet in the frame and provide PHB for dscp 32 ?
Much appreciated!!
Have a great weekend.Hi
No it will not trust the cos value, because You have configured to trust dcsp. So, the switch will trust the dcsp value in the incoming frame.

SRW224G4P uplink to catalyst 3560 switch trunk
I have many SRW224g4p switchs,and I use a catalyst 3560 for a core switch.
The SRW224g4p uplink to 3560 switch
What can I config the port of the 3560 to SRW224g4p(Their are many of vlans in my network)
and config the port of SRW224g4p to 3560's port
ps:config trunk port problemHi Wei,
Are you working on the Linksys SRW224G4P or the replacement Cisco (300 Series) SRW224G4P-K9-NA? Can you attach your 3560 Truk Port Configuration along with the VLAN Configuration?
Thanks,

Physical position of backup Cisco 3560 switch in relation to other produciton switches
We currently have three 3560 switches connected to each other using SPF interconnect cables. I have a backup switch ready in the event one of the three switches fails. I'd like to keep the backup switch configured and in the rack connected to the three switches. If a switch fails, do the interconnect cables have to be routed in the same way they're currently setup or can they be connected in any order. In other words, if I have the replacement switch in the rack at the bottom with the other three switches and the top switch fails, after loading the config of the top switch onto the replacement switch, can I keep the cables from the second switch connected to the third switch and run the interconnect cables from the failed switch, now switch 1, to the third switch, which is situated in the rack just above the replacement switch?
Thanks in advance.Disclaimer

For 3560s, what SPF ports you use doesn't really matter.
If the backup will be a cold spare, you may need to worry about port configurations, before you connect it.
If the backup will be warm spare, again, you can interconnect the SPF ports however you like. If, though, you create any L2 loops, you need something to break the loop, e.g. STP, FlexLink.
If you want intentional redundancy, the simplest configuration would be a ring, and assuming the backup is just a warm spare, a root switch defined with the other two non-backup switches connected to it (on the ring). (The backup would connect to the two non-root switches.)
Besides a ring topology for redundancy, you might setup a dual star topology, or as you only have four switches, even a full mesh. -
ESW520 connected to 3560 Switch
I have an ESW 520 switch that is connected to a 3560 switch.
The 3560 switch is connected to a windows DHCP server.
I need to ensure that dynamic addresses are being sent to clients/workstations connecting to the ESW 520.Those workstations connecting to the 3560switch can obtain dynamic IP addresses but those on the ESW cannot.I have tried all i can to get the workstations behind the ESW get dynamic IP addresses from the Windows Server,but all effort proved abortive.
The vlan for data vlan is VLAN 300.
I would need someone who can help with this.Hi Harlan,
Have a look at this recent thread that details two different software sloutions for this. This includes one kindly written by fellow NetPro Rob.

Private vlans and 2960 and 3560 switch
Hi, I have a 3560 switch that supports private vlans. There are few computers connected to it and private vlans work fine. Now I need to connect a 2960 switch to 3560 switch. 2960 seems to have no private vlan configuration options but it can be private vlan edge? What is private vlan edge? If I put the computers on 2960 to a vlan that is isolated vlan in 3560 will the computers be able to communicate with themselves in layer2 on 2960 switch?
Example: I have network 10.0.0.0/24. Networks primary vlan is 2001, isolated is 2002 and community is 2003. These settings are on 3560. So if I put computers on 2960 switch to vlan 2002 and make the ports protected ports they will act as isolated ports and they can't communicate with ports that are on isolated vlan 2002 on 3560???
Can I also use the community vlan on 2960? is this possible because vlans 2002 and 2003 would be on the same network??? -
MTU Size Issue on Cisco 3560 Switch
Could anybody tell me how to change MTU Size on a Cisco 3560 Switch.i mean to say whether it is to be changed on FastEthernet Interfaces or on VLAN 1 or on Global Configuration Mode and with which Command to change it.
I am using MPLS on my Routers and the MTU size i have set on my Router Interfaces is 1524.
When i do a normal ping from Customer's one site to another (where my Traffic has to pass through this Switch VLAN)i get a reply , but when a Ping with a Byte Size of 1500 or more the Packets get completely dropped.
I think due to MTU Mistach bet. Switch and Router the Packets r getting droped,that is why i was trying to change it.
could the Packets get dropped because of this reason.Please suggest. -
DHCP and voice vlan on Cisco 3560 switch
Greetings,
I'm setting up a Cisco 3560 switch for voice and data comms. I'm looking for documentation with best practice guidelines for the following requirements.
1. Using the Cisco 3560 as a DHCP server - Config examples. Do I need to use different subnets for the voice and data vlans?
2. Layer 2 CoS QoS - I'm connecting Aastra phones as well as notebooks - I've been told that Aastra also makes use of the voice vlan config through LLDP and that Aastra phones supports CDP.
Your assistance will be appreciated.Hi ,
Cisco recommends that you have a separate vlan for voice and data with different ip subnets for voice and data. You will need to configure the dhcp pool accordingly.
Here is the config guide for setting up IOS DHCP server:

Setting CoS value in 3560 switch
Hello,
Can someone help me how can I set the CoS value under policy map in Cisco 3560 switch IOS release 15.0. It gives me the option to set either IP Precedence or DSCP but there is no option for setting Class of Service (CoS).
Please see attached screenshot for clarity. Thanks in advance.
TilawatThanks Reza for responding. However, I want to assign the CoS value based on some classification specified in class map like MAC address. Therefore, I am considering this to be under policy map. How can I mark the traffic with some CoS value based on the classification. I just don't want to assign CoS to every frame that lands on an interface of the switch by adding CoS to the switch interface.
Thanks,

Why does the App Store not work in Genius with VoiceOver switched on
After I downloaded IOS 6 to my iPhone 4 there were a lot of things not working properly, the main things that were a problem was the App Store, to move anything with VoiceOver switched on it was touch-and then tap twice also to move the thing on the page you use three fingers swipe up or down left or right to move it. We now find that to move something in Charts you only need one finger touchon the left to move it.If Some body can come up with thee answer it is the People that work in the Accessability side of things at Apple. So if you know in Ireland why Apple cannot put in the info for Accessability for People who are Blind like me we cannot see what is going on we do not change anyof the settings...
Thank you very much for the reply. That certainly makes sense, as I am sure it is all the Time Machine backups I have that are at the root of the problem. How can I update all those older version Apps deeply embedded within my TM backups, or is the solution to unmount my 2TB drive that I use for TM?
I suppose if Apple could somehow direct the App Store to disregard all those other apps in TM, the problem would be resolved.
