i have 300 user in network in 2 building and firist buiding 5 flors.i use subnet /22.i have core switch 3500xl fiber and 8 swith 3560 and my network have 2 router one for adsl and other for mpls so i want upgrade it to make voip network and wireless
so if i need replace switch what i model and how many?
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.
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.
I have two 3560s that i would like to upgrade. But first i would like to make -absolutely- sure i dont wind up in a situation where i have to roll back over a console connection.to the day i still cant understand why oh why someone removed (or chose not to implement it everywhere) tftpdnld from rommon ;)

View 4 Replies View RelatedI 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 wanted to upload image having .tar extension in Cisco 3560 switch. What are the steps to upload.

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?
I have a Cisco SG 300-20 as the core switch, layer 3. It is 192.168.4.6 on VLAN1 and 192.168.5.1 for VLAN2 (VOIP). All the ports are set in trunk mode. DHCP relay is setup on this switch.
The phones connected into a layer 2, Catalyst 2960-S switch. All ports are set in trunk mode. Default gateway on it is set to 192.168.5.1.
DHCP for both VLANs is provided by a Windows Server 2008 R2 server (the relay IP 192.168.4.15).
There is also an ASA 5510 in the mix which is 192.168.4.1. It has a route added to it for the 192.168.5.0 network to go to the SG 300 (192.168.5.1).
Just the two switches can ping each other on the 192.168.5.x network when I "add vlan 2" to the trunk port that is connected between the SG 300 and the 2960. The phones don't get DHCP on the 2960 switch. And I cannot ping 192.168.5.x from the ASA or anything else on the 192.168.4.x network.
After a bit of reading on intra-vlan routing for the SG 300 switch, I am thinking the SG 300 has to be the "center" of things so I need to make it 192.168.4.1 to be the gateway for both VLANs and change the ASA to 192.168.4.2 for VLAN1, etc. And I really can't do asymmetric routing with this switch.
I read some papers about QoS. The thing is that I have to implement 30 switches with QoS to connect to a lot of Cisco IP phones. The switches are Cisco 2960S with code image "C2960S Software (C2960S-UNIVERSALK9-M), Version 12.2(55)SE3". Should I use autoQoS feature or manually configure them?. How should I treat uplinks between access switchs and core/distribution? I have a lot of doubts regarding queueing, because all the info I had read its for another model/image.

View 2 Replies View RelatedWe are going to be expanding our Shoretel phone system in our HQ and I need to get QoS configured correctly. All of our offices are connected via MPLS and I need to make sure that we are sending QoS tagged traffic to our provider. The phones are tagged by the director, but there is other traffic for call control that needs to be tagged. I don't have access to our CPE router as it is managed by Sprint. The Sprint router is connected to our internal network. We have our data network running on (4) 3750x switches running 12.2(55) with IP feature set.
The problem is that many of these commands don't work on the 3750 (priority, bandwidth, match protocol, etc...) and the configuration assumes you are applying this to an outbound queue which is not supported on the 3750. I think I have to do this with policing, but I'm not sure what interfaces need to have this applied.
I'm looking to configure the QOS for VOIP on my network.I have a switch SG300 and several no Cisco VOIP phone. What are the parameters to be taken to implement the QOS?
What is the procedure for installing the QOS? I need to create a VLAN for the data and one for VOIP?I read in the quick start guide that there is auto-QOS for VOIP?This can be done from the GUI? what are the options to put?
I am planning to upgrade the current core switch(3750) to 6509 series switch. Since we have a production network running we have to plan for an online core switch upgrade.

regarding QOS on Nexus 7000. Our Nexus 7000's form a collapsed distribution/core layer, our access layer switches are are a mixture of Cisco 3750 & Cisco 4507. 3750 switches will connect to Nexus switches via 1Gb uplink, 4507 switches will connect via 10Gb uplinks. Each Nexus will be connected via 20Gb port channel, all servers connect to the Nexus switches via 1Gb links. We're implementing a new telephone system soon which will be using VOIP so I need to configure the switches to perform QOS. The IP phones will mark the RTP traffic with DSCP value EF and call signaling traffic CS3. I'm fine configuring qos on the access layer switches, its just the Nexus switches which I'm not sure about.
Do I actually need to configure any QOS parameters on the Nexus switches so they will prioritise the VOIP traffic. If my understanding the Nexus switches will trust the DSCP values and assign the traffic to the relevent queues?
Just for information VOIP is the only traffic I will be marking QOS values
I am unable to find a sample config that doesnt use autoqos.

Vlan 900 is a VoIP VLAN
Vlan 999 is a NULL VLAN and is shut down:
interface g0/1

switchport mode access
switchport voice vlan 900
mls qos trust cos

The 6901 phone doesn't support multiple VLANs, so our configuration above does not work unless vlan 999 is turned on (not good security wise). We got the phones to work also by removing vlan 999 and switchport mode access.
switchport voice vlan 900

solution that provides the discarding of data for the access VLAN, while supporting the VoIP vlan for this phone?
Are there any differences between the autoqos commands on a WS-C2960S switches (or in any other series)? Follow the commands:
- auto qos trust
- auto qos voip trust
I was checking the documentation on this link:
URL
And couldn't find any great difference between the two commands, as far as I could see they'll set the Ingress and Egress queues the same way.
Are there any differences between those two commands (auto qos trust and auto qos voip trust)? If so, when should I use one and the other?
im having this strange issue where everytime i plug in a voip phone to my 3550 the switch disconnects another voip phone.then to fix the disconnected phone (7940) i need to power off the phone 5-10 minutes then power it on again.
but the strange thing is, once i have to do that to fix the phone and connect the phone back to the switch, the port link is up, but no macs are seen on that port.
All of our VoIP phones bounced (re-registered) in the middle of the work day and we do not know why. There is no maintenance going on at this time. The phones came back up right away. Upon further investigation, I only found one error message on our core switch (WS-6509 running IOS ver. 12.2(18)SXF13) and I'm wondering if that was the cause:
Jan 3 13:51:04.030: %SIBYTE-SP-5-SB_OUT_OF_RX_DSCR_CH1: Out of RX descriptors on mac 0 - channel 1 (count: 299)
I cannot find any other instances of this error message from the internet.
I have two Catalyst 3560 series switches with a 100Mb Ethernet microwave link and a 250Mb Ethernet microwave link between them. Can the switches be set up to make full use of the added bandwidth (350 Mb).
