Cisco Switching/Routing :: 3560 IOS Upgrade And PBR

Nov 21, 2012

I have a 3560, which is being used as our core router that I have recently installed. It still has the standard IOS which came with (C3560E-UNIVERSALK9-M) it but I need to implement policy based routing so need to upgrade it and have downloaded c3560-ipservicesk9-mz.122-58.SE2.bin and indeally would like to install it in the morning before people start work.

I have 2 questions, 1, Is the ipservices capable of PBR as I have been reading conflicting reports, in fact my friend who works for Cisco has advised that it is not possible on the 3560.

2, When I do upgrade will there be any current configurations that are not compatible with the new one, I wouldnt image that there would be any but just wanted to make sure as it would be the biggest headache ever if it went wrong.

Cisco WAN :: 3560 Network Upgrade And Int Vlan Routing

Dec 7, 2011

I want to give a breif overview of the current setup and what I had planned to do in the future.  This is also where a few questions come into play.  Currently we have 3 10.x.x.x subnets between three buildings with a wan connection.  This connection is invisible to us so it can be seen as just a lan.  The speed is 100mb.  We have a 2811 router sitting at each building translating their traffic back to  We then have a router in the main building which ships the 10.3.x.x traffic to a ASA and then out the door to a ISP.
My plan was to upgrade this 100mb WAN connection to 10g fiber between our buildings as they are in extremely close range of each other.  I would need a equipment upgrade as a 2811 won't support 10g traffic.  Rather than replacing 3 routers in each of the buildings it seemed logical that I could get something like a catalyst 4500 or 6500 and do int vlan routing making it all one huge campus lan.  Creating a vlan for each building to segment the traffic between them.  My understanding was that a cat 3500/4500/6500 did not need a router with sub interfaces in a one arm setup to bridge this traffic.  This is where the problem comes in.I tested with a cat 3560 and was unable to get the vlans to route correctly.  Do I have to have a router to get int vlan routing to work?  If so then I might as well get a Router which can handle multiple 10g fiber for the core instead of a cat 4500/6500 since I'd need the router to do the int vlan routing anyway?

Cisco AAA/Identity/Nac :: 3560 Dot1x Failure After IOS Upgrade To 12.2. (55) SE1

Apr 5, 2012

This weekend we have upgraded the ios on quite a few switches on a larger site, the site is a mix of 2960 and 3560 switches and the previouse ios versions were 12.2.44 on most switches but some had an older 12.2.25.On monday when we came into work we got a call that most of the ports on these switches were an amber color and most people could't use the network.After some investigation we discovered that we had a problem with dot1x so for a quick solution we just removed it from the switches and restarted all the ports with no dot1x enabled,[code]

Cisco Switching/Routing :: 3560 IOS Upgrade On Production Network

Nov 21, 2012

Looking for input/thoughts on the upgrade of our 3560's and 3750's while on production network.
While we could remotely send the IOS over the network to the device, I'm concerned about errors and the lack of physical control of the device. So, the thought is to just go to the comm closet, plug in with laptop to the console port, and upgrade the IOS over the console port. But this would require xmodem, correct? I know the fastest way would be to a. configure an empty fa0/0 port to no switchport, add an IP address, and use tftp. BUT, we would have to isolate the switch from the production network while connected to it with our laptop. Otherwise, our laptop would be seen on the network as an unknown device, and there would be repercussions...
So, we console into the device, and u/l the IOS that way. Is there a way to increase the baud rate on the switch to 115200, change putty to 115200, then do the x modem? I just say we should shut all the ports to isolate the switch from the network, then tftp the IOS to the switch. Unplug, reopen the ports, then reboot the switch.

AAA/Identity/Nac :: CSACS-1121-UP-K9 - Possible To Upgrade It Being Non Upgrade Part

Sep 10, 2012

Is it possible to upgrade the CSACS-1121-UP-K9 to be a non upgrade part? We were going to upgrade from a Windows 4.x to the above Appliance (version 5.x) but there is now a reason to keep the old Windows version running therefore we cannot give the new Appliance the old ACS's licenses?!So we should have (with hindsight) bought a fresh version of the ACS 5.x rather than an upgrade.

Cisco WAN :: Qos With 3560 As Hub

Jun 19, 2011

We have a 3560 on our head office acting as an aggregare switch as well as Hub terminating remote wan links(one trunk link from provider terminated on FE port with several SVIs for remote location) and routing via OSPF. We have 1800 series at remote locations.
Now, If I want to prioritize say SQL traffic outbound from our head office to each remote brach I cant seem to do it with 3560 as it says... cannot apply service policy out blah blah.
How can I achieve my goal with 3560, Is it a good design to use 3560 as a Hub? our port utilization isnt that much..Wouldnt it be better to use 1800 or 2800 series?

Jun 6, 2012

We have a problem with our WS-C3560V2-24TS running IOS c3560-ipservicesk9-mz.122-53.SE2.bin. The equipment keep dropping packets for no apperent reason.
This is what we are seeing:
Router0#sh interfaces fastEthernet 0/2 | include drops:
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 20595


We are shaping the gig uplink to 100Mbps, the equipment is dropping pakets randomly and not because the shaper kicks in and starts to drop pakets.

The access point cannot join the controller. Is this a misconfiguration at the WLC or something else?

Cisco :: 3560 Trunking With Dlink

Apr 1, 2012

my current network setup is like this.. a cisco 3560 is connected on an access port to an adjacent dlink stack. i want to enable trunking between the cisco and the dlink. what i know is that dlink doesnot support per vlan STP while dlink only run single instance of the STP.. how can i make the trunking possible without messing with the network.

the idea that i have is to run MSTP instance on the 3560 so that it appears as a single STP to the dlink switch and then all good. is there any other way to do that. if i just make both the adjacent ports on both the switches as trunk and connect them, will it cause any problem in terms of STP issues or convergence ?

Cisco WAN :: SRR Input Scheduler On 3560?

By default there 2 input queues. 2nd is priority queue and has 10% of link assigned. Weights for two queues are 4 and 4. For example we have 1Mbps link. ANd we also have saturated link with voice and other traffic. Will voice get 550k bandwidth? As I undestood 100k is assigned to voice strictly. Remaining 900k is evenly divided by two queues according to 4 and for ratio.

Cisco LAN :: 3560 Network Design

Apr 1, 2012

I'm working on a new network design for my company. We're expanding and opening some more offices and satalite sites. We're a UK based company but opening some US sites.We have a main UK office (Office A on the diagram) a call centre (Office B) and then two buildings on another site (Office C). The USA offices will be very small and only require a couple of computers, hence the small IP allocation. I have marked the IP addresses of the links on the diagram, I intend to use 3560 switches for all the switches marked and all links will be layer 3 to route multiple VLANs from each site to each site (where permitted). question is this: How do I achieve this in the switches? I'm thinking that OSPF is the way forward, is this right? I want to do as little configuration on the switches as possible to allow for dynamic updates of the network (i.e. I don't want to add static routes for everything).

Cisco WAN :: 3560 - How To Route Segmented LAN

Jul 13, 2011

The traffic flow on the network is fine, but we are not able to access our remote locations.Using the example in that thread:Let's use your example.  If your Vlan interfaces are configured on the 3560:
interface Vlan10
description LAN A
ip address
 interface Vlan 104
description LAN B
ip address
Device  A has his default gateway set to (interface Vlan10) and  device B has his default gateway configured to (interface  Vlan104). If device A ( wants to talk to device B  (, the traffic would have been routed on the 3560 between  Vlans 102 and 104.
As  for DHCP, if there is a server on a separate network (let's give the  DHCP server an ip: you would configure an 'ip  helper-address' on each vlan, which will forward each DHCP Discover  broadcast to the DHCP server as a unicast packet.  This is done because  by default the router (3560) will not forward broadcasts.
interface Vlan10
description LAN A
ip address
ip helper-address
 interface Vlan 104
description LAN B
ip address
ip helper-address
Now lets say LAN A and LAN B are located in SITE1. A second site, SITE2, has the address of I can't ping the Site2 location from the LAN B (10.20.104.x) segment in Site1. I think I should set a static route on our switch with something like this:
ip route
The address would be a wan router in this example.

Cisco LAN :: 3560 - Add Second / Sub DHCP Pool?

Jul 25, 2012

We have the configuration below set up in a 3560 switch (addresses and names modified for privacy). We are running out of dynamic IP’s in the current pool ( – We have a new set of IP’s that we can use ( – – an additional 512 addresses). Although I can figure out the commands to add a new dhcp pool, secondary subnet, etc., I’ve never done this before so I’m not sure of everything I need to do. The end result I need is that the 3560 needs to be able to hand out IP addresses from the current and new pool to anything connecting to vlan 300 – our datanet where computers access the Internet. What I need to do as far as modifying the vlan, adding the secondary subnet, defining helper IP’s, gateways, whatever, so that computers connecting via vlan 300 have Internet access via either of the pools?  I have been told that all I need to do is create the pool, but not sure if that is correct...

Cisco Firewall :: 3560 / 2960 - QOS For ASA

Apr 17, 2013

I have a question regarding QOS and possibly dedicated bandwidth. The environment is ISP goes into an ASA that up links to a 3560 and fiber up links to other 2960s throughout the building for internet. My question is for certain sections of the building if I segment the network can I guarantee them a certain amount of bandwidth. For example, if 1 gigabit is coming into the building from the ISP and into the ASA, can I guarantee one room in the building no less than say 200 Mb of the full internet pipe at all times?

Cisco WAN :: Multicasting Configurations On 3560 SW

OK, in this is it necessary to configure "IP Multicast-routing" on the switches? Do I configure PIM on all interfaces that will handle multicasting (router and switches?) If PIM is enabled on the 3750 do I need PIM configured between the 3845 and the 2821 ? Do I configure the Auto-RP on the 3750 or the 3845 ?
