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.

1-As this is stackable switch do i need to upgrade on all Switch..i can see there are 3 flash while doing show flash?
2-Is above IOS image support with my switch? do i able to enable ssh?
3-is flash memory is enough to succefully upgrade IOS?

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.

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 10.3.1.1. 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?

I've been searching the forums to see if any other users have completed this type of configuration successfully with not much luck. I have a Cat 6509 currently in production. We have several Vlans and all communication and routing is funtional in our environment. We are going to be adding an iSCSI Storage environment, and within a couple of months, adding a 3 Host VMware farm. I've configured several iSCSI environments using dedicated switches for the iSCSI network but never to existing production switches.My thoughts are to add two iSCSI Vlans outside of the production IP Scheme to the 6509 with no SVI, attach storage controller's NICS ports to the management network and of course, other available NIC ports to the iSCSI network. My question is, what is the best practice in configuring the 6509 i.e. switchports, Jumbo Frames, Flow-Control to support iSCSI on a 6509 that is in production and what are possible risks if any with enabling Jumbo Frames, Flow-Control etc?

I have a CAT 3560 connected to a ISR 2911 The 3560 has 2 subnets ( 192.168.1.0 /24 and 10.10.10.0 /24) The 2911 has interface GigabitEthernet0/1 on the 192.168.1.0 /24 and another GigabitEthernet0/0 on a WAN connection 172.16.7.246 I need to NAT both the 192.168.1.0 /24 and the 10.10.10.0 /24 to the single address 172.16.7.246 I have to use route-maps . I have IPSec VPN's and ZBF on the 2911 My problem is the NAT does not work for the 10.10.10.0 /24 network!Why?is my only option to use trunking between the 3560 and 2911 and subinterfaces on the 2911? I want to avoid sub-interfacing.

I have 5 linux and 3 Microsoft 2008 Servers, each connected to 2 Cisco 3560 Switches. The 2 Cisco 3560 switches are connected to 2 different Cisco 515e Pix. Is it possible that if i enable Port SPAN in any of the switchport and send a copy of traffic to any of the windows 2008 server, will i be able to monitor the bandwidth of the servers (Here I am only looking for traffic going from servers to PIX and then to internet, also vice versa).
Also will wireshark be able to differentiate specify the bandwidth of each servers seperately ?

Our network feels slow and trying to find the best way to investigate this properly. We have Cisco chassis 4500 with mix of 3560/2950 Edge switches 1GB backbones and WLC/WCS in place. The network is broken into multiple V LANS and IOS on our switches haven't been updated in 3-4 years.
On a wireless laptop (G) with get throughput of 1-2MB/s transfer speed with usually 10 clients per AP and LAN we get anywhere between 7-15 MB/s transfer. Using wire shark on a wireless laptop we see a lot broadcast traffic from other clients and the same for LAN. What is the best way to troubleshoot performance issues on the network and where do I start?

This is a real world project. A Cisco 1700 series router will be installed at one location and a ADTRAN 1224R router will be installed on the other side. I’d like to test it before installing at client-side by using a Cisco 2800 and the ADTRAN mentioned above. I made a T1 crossover cable and CD led is green on 1DSU-T1 V2 of 2800.
I believe something is wrong with clocking. I used service-module t1 clock source internal command on 2800 to provide clocking and set ADTRAN clocking to Line BUT If I reboot the ADTRAN, while debugging service-module on 2800, I can see this:SERVICE_MODULE(Serial0/1/0):Unit has no clock [complete output is below].
And even if I swap clocking sources, still get the same output on 2800 as above.PPP requests sent from either sides are not acknowledged. [output below]
I get Se0/1/0 PPP: Authorization required every a few seconds on 2800. [output below]
Cisco 2800 (hostname MEE_KC)
1. sh run
username MEE_GF password 0 w1ll0w
interface Serial0/1/0
ip address 100.100.100.1 255.255.255.252
encapsulation ppp
service-module t1 clock source internal
service-module t1 fdl ansi
ppp authentication chap pap
2. sh int s0/1/0
Serial0/1/0 is up,
line protocol is down
Hardware is GT96K with integrated T1 CSU/DSU
Internet address is 100.100.100.1/30

The last few days I've been exploring options in getting rid of some old routers accross a wan connections. I have a cat 3560 to play with and I thought I would try and use the no switchport command test out routing with switch. I've got some type of route issue and I tried a few things which I thought would fix the issue but had no effect. I'll post the config and a few commands so you can see what the basic setup is.
Here we can see in the arp that it knows about both 10.7.1.2 (PC unable to ping 10.3.3.254) as well as 10.3.3.254 (ASA).I tried adding in a ip route of 10.7.0.0 255.255.0.0 10.3.3.110 as well as 10.3.3.254. Neither produced the results I wanted allowing 10.7.1.2 (PC) to ping the ASA (10.3.3.254). [code]

I have an environment of 3 X 3560G of which I have 1st switch-CORE(f0/10) connecting to the VPN router(CE) interface-f0/0. Remaining 2 Cisco 3560's(Access) are connected to Gi0/1 and Gi0/2 on the 1st switch-CORE via gi0/1 . On all three switches I have created multiple VLANs and assigned ports to these VLAN. The switch to switch connection is trunk allowing all VLANs created on all these 3 switches. Now the issue is how I am going to have all these VLANs routed through single interface on the routeri-e f0/0, as all these subnets will communicating to remote site over VPN. What should be default gateway on the 2 Access switches and the CORE switch, also what static route should be on router to reach all subnets(VLANs) created on these 3 switches.
I have read inter-VLAN routing i-e creating sub interfaces on router but dont want to proceed with that and looking for any other way to have my VLANs talk on all three switches and then are accessible to remote site ove VPN?

I have tried to make policy based routing on Cisco 3560. I use ipservices ios (SW version 12.2.(50)SE3 and SW-IMAGE C3560-IPSERVICESK9-M) For below configuration there is no problem and pbr is working.
“Access-list 100 permit ip host 1.1.1.1 host 2.2.2.2
Access-list 101 permit ip host 1.1.1.1 host 3.3.3.3
Route-map pbr1 permit 10
Match ip address 100
Set ip next-hop verify-availability 1.1.1.2 1 track 11
interface fasthethernet 0/1
ip policy route-map pbr1”
But when i add another sequence to the "pbr1" with another sequence number like that.
“Route-map pbr1 permit 11
Match ip address 101
Set ip next-hop verify-availability 1.1.1.3 1 track 12”
pbr is not working. Switch gives message "PLATFORM_PBR-3-UNSUPPORTTED_RMP:Route-map pbr1 not supported for Policy Based Routing”"ip policy route-map pbr1" command not shown in the running config. And "show ip policy" output is blank.Configuration guide says you have insert many sequence to the route-map with the same name. And also this command is not in the unsupported command list.

We recently purchased Cisco 3560X Layer3 Switch. We need to perform simple Inter VLAN routing. We have configured VLAN1 (name-server_vlan) and VLAN2 (name- user_vlan). We have also assigned the Ports and IP address to both the VLANs. After assiging this if we plug Laptop A into VLAN1 then it doesnt communicates with Laptop B (btw, Laptop A is able to Ping VLAN2 Gateway ) in VLAN2 but on the other hand Laptop B is able to communicate with Laptop A and ping everything i.e. Gateway of VLAN1.

We have two catalyst 3560 switches running c3560-ipbasek9-mz.122-58.SE2.bin They are connected using etherchannel using gi 0/21 - 24 interfaces.
on 3560-1 switch, there isn't any ip-default gateway or ip route configured. It only have 1 interface vlan configured.
on 3560-2 switch, there is ip default gateway configured along with 1 interface vlan.
What i dont understand here is that, i can reach out to other subnets from 3560-1 switch in which the routing is not enabled?

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.
I've attached my 2800 and 3560 configs.

I have a 3560 POE that will no longer boot and I am not able to load a fresh copy of software onto it. It appears that it has lost all data. When I attempt to TFTP a new IOS, I receive that following error:
Transfer cancelled by remote system
I have tried using dir flash: to see what is contained in the flash directory but I receive the below message:
unable to stat flash/: no such device
I am stuck in rommon mode so when I do switch: dir command, I don't even see flash as being a filesystem. The below list are the only systems registered.
bsdcs[0]: (read-only)
bstage[1]: (read-only)
fstage[2]: (read-write)
xmodem[3]: (read-only)
null[4]: (read-write)
tftp[5]: (read-only)
Is this switch finished or is there something else I could try?
