I am not on site and I have not seen a WS-C3750V2-24PS-S. Customer has a stack of 6 x WS-C3750V2-24PS-S and one unit has failed. We do not have a WS-C3750V2-24PS-S spare. Can we replace it with a standard WS-C3750-24PS-S (not V2) switch and be part ofthe stack.
1. Are there any traps gotchas?
2. What about IOS versions - aren't they different for V2 switches
3. Are the stack ports and stack cables same for both WS-C3750V2-24PS-S and WS-C3750-24PS-S
4. What is the main reason for bringing out the V2 switches. What features do they have extra?
is possible to have WS3750G-24PS in one stack with WS-C2960S-24PS? I want to add two new WS-C2960S-24PS to stack with one WS3750G 24PS.

I have three new 2960 switches as listed in the title. I configured them as follows:
192.168.1.215 host: whse-c
192.168.1.216 host: whse-b
192.168.1.217 host: whse-a
Switches B and C flow into A before continuing on into the server room switch (distance issues).All three switches are configured for ports 21-24 at 1000 and set as cisco switches. all other ports are undefined as they have a myriad of desktops, printers and non cisco access points flowing into them. side question - should i configure them as access points where applicable even if they are non cisco? I am replacing three netgear switches that currently are in place and have no known issues other than they are old and the fans may fail soon.hooked up .217. was able to get to it from the network. Hooked up 215 and then 216. All the sudden I lost the ability to tap into the switches, any of them. (I think I had done 215 at that point too, before adding 216. I found out later it took the network to its knees as internet was lost, and the MPLS stopped functioning.
I undid the changes and put the netgears back in service and all was right with the world again. At first I thought it was a bad host name as I had used whse-a on switch C in error. I changed that after this issue.Later that day I put 215 in place. checked it from the network and could get to it just fine. Then I put 216 in service. I lost connection to 215. I could no longer get to the internet from my pc and the MPLS went down again. This time I just unhooked 216. 215 is still in place and working on the network at the moment and not causing issues. (btw these switches are not even in my path from my pc to the internet, just on the same network) tomorrow I am going to try 217 again while 215 is still on the network and see if there are any issues adding that swtich. if I can do so, and there are no problems, is this an indication of a faulty switch? what further testing can I do, have I missed something in setup? If this brings the network down again, why cant i add two of these switches to each other/on the same network path (B and C were not even connected to each other yesterday evening when it went down again).
I am having an issue with VoiP phones giving me an insufficient bandwidth message. I have three remote locations connected to our main building using 2 Mb point to point ethernet solutions through TWC. Each remote location has a Cisco WS-C3560-24PS running IOS C3560-IPBASE-M, version 12.2(25) and have the cable modems plugged into port 1 on them. The remote buildings are labeled 192.168.101.xxx, 192.168.102.xxx, and 192.168.103.xxx. There are 14-16 VoiP phones in each remote building. The main building being in the subnet of 192.168.100.xxx. I have the 3560s connecting to a single port on a 2801 in the main building, all using the subnet of 192.168.253.xxx The phone server sits in our network at 192.168.100.203. I have created the ACLs, class maps, and policy maps on all of the equipment.
For the remote buildings I have the following:
ACL
===========
Extended IP access list VOIP
permit tcp any host 192.168.100.203 dscp ef
permit tcp any host 192.168.100.203 eq 5566
[Code]....
I have put a hub in to capture traffic via Wireshark to see if DSCP flags are being appropriately marked and I do see that all VoiP packets are getting marked with as EF. However, I have been receiving phone calls from people in the remote buildings stating that their phones will cut out, flash Insufficient Bandwidth on the LCD displays and then the call will cut back in. I am wondering if the 2801 is not applying QoS with the rate-limits in mind since it is set to 100 Mb, or is it an issue with trying to take 3 remote locations and bring them down into 1 port on the 2801?

View 2 Replies View RelatedI have a WS-C3560G-24PS service as a distribution switch with six (6) WS-C2950T-24 connected to it. In looking at the utilization on the inter connect links no one is running close to a gig speed and this includes the link between this switch and the core. The CPU load (6%) and memory utilization (30%) on the switch do not seem bad so what else does one watch to see if it needs an upgrade?
We are starting tohave discussions about any needed upgrades on the network. I have an ocassional user that complaines about low performance but looking through the network I can find nothing glaring on a consistent basis that says an upgrade is warranted. I am however looking at things such as the above. Utilization on links, CPU, memory, etc.
I've been experimenting with the 'vlan dot1q tag native' command on a switch and it seems as though tagging the native vlan breaks vty access to my access point.With the 'vlan dot1q tag native' commnand applied, I lose management connectivity to the AP with 'no vlan dot1q tag native' applied, connectivity is restored. Why is this? Is it safe to say that one can access the AP via vty lines using ONLY untagged packets?

We have a Cisco switch in each office and every now and then the port that has the D-Link Wireless AP (DAP-1522) connected to it goes to err-disable state. Actually sometimes even a regular port that has a cisco phone connected may also go to err-disable state (less often). So I have to telnet into the switch and issue shut and no shut command on that interface to get it back to life, then it works for a few days or weeks until it happens again. Any suitable configuraiton for that interface, that would prevent that from happening or a workaround ?

View 8 Replies View RelatedThe 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

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.

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, 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 configured following command to implement QoS on Cisco 3560.
class-map match-any IND
match access-group name Lync
policy-map LyncAV
class IND
set ip precedence 4

how to apply this QoS on interface?

I have issue with 3560 switch QoS configuration . I checked in cisco site about mentioned model QoS configuration.once we mark the frame and map the CoS to DSCP and once it enters into switch and it processes according to LAN QoS configured on interface
we have configured both the commands shape and share.
once it leaves the switch and enters into Edge router and if we do not have configured QoS in router which is normally MQC , how does it process each packet ?Do we need to have end to end QoS configured in LAN ?
