We are moving a small network of 3560 and 3750X switches from VTP Server and Client to VTP Transparent. I noticed the vlan database is stored differently depending on the VTP mode.
Is there any chance of losing vlan database on a given switch when moving from Server or Client to Transparent?

I have a 3560 series switch and two comcast cable modems. I connected the modems to them switch via cross over cables and set an OSPF routing on their subnets. I connected my wireless router to another port of the switch and set its gateway IP on the switch port. I can ping the modem with the switch and I can ping the wireless too. But I cannot access to the Internet via the wireless router.
I need load balancing on two cable modems and get a single network connection via the wireless router.

How to configure cisco 3560 to force the client only can get ip by dhcp-relay server ?
The company i am working in has 5 vlans which have been set an lay-3 switch(3560), uses the dhcp-relay server .(in svi configuration: ip helper-address X.X.X.X) well , that works ok~
Now , I got my problem: I need to force the client only can get ip by dhcp-relay server, that means if anyone set static IP manunally , he can't really access to anywhere (to provent anyone set static IP with malignancy )
I know if a h3c router , how to set this configuration n svi configuration : dhcp relay security address-check enable )
the how to configure on a cisco 3560 ?

In one location we have a HP 2510-48 port switch which we need to connect to a Cisco 3560 switch. The problem I have is that we have issues connecting fibre to the HP switch, so I have decided to attached a CAT 5 to Fibre convertor at this end and another to the cisco switch.
My question you can not connect a HP switch to a Cisco switch, is this true or do I just need to confirgure something on the ports.

I want to replace an existing 3560 Switch with another switch of the same exact model and IOS. However, this switch that needs to be replaced is the VTP Server of my LAN at this location. When I replace the switch I will just use the same exact running config but I'm concerned about the vlan.dat file. Do I need to copy that file over to the new replacement switch and if so, what is the best way to do that?

I'm trying to connect Switch 3560 to NTP Server based on Linux, the NTP is working fine but the switch is sync with the Server:
address ref clock st when poll reach delay offset disp
*~10.0.0.70 208.53.158.34 3 42 64 377 1.7 -2.49 0.1
* master (synced), # master (unsynced), + selected, - candidate, ~ configured
Clock is synchronized, stratum 4, reference is 10.0.0.70
nominal freq is 119.2092 Hz, actual freq is 119.2093 Hz, precision is 2**18
[code].....
But server has on time and the Switch another. I test this NTP with CUCM and is working fine, the issue is with ther server?

I have a 2 cisco switches that are at different sites one is a Cisco CAT4500 and other 3560. The connection between the switches is a layer 2 fibre link. CAT4500 and 3560 both have VLAN interface ip addresses in order for me to connect to the switches.
I have PC A connected to CAT4500 and PC B connecting to 3560. All these devices are the same VLAN and in the same subnet. I do have trunk links all the way though allowing this vlan as we run vlans. From PC A, I can ping CAT4500, 3560 and even PC B. This tells me everything is fine regarding Layer 2 & 3.
As soon as I move PC B and connect it to the other switch CAT4500 or move the other PC vice versa (this happens in both directions). Both switches learn that the mac address has moved locations and updates its mac address table accordingly. So when I do a show mac address table and show arp, everything has learned and moved fine. However when I try to ping any other device from PC B I cannot. So the 3560 switch PC B was originally connected to, I can no longer ping, the switch cannot see the pc also. It is as if PC B has not learned anything from the switch and cannot respond or reply to any icmp. I have tried this with different end devices, same thing. I am now thinking it has something to do with the switch.

i am not sure if this is something with my DHCP setup or not, but it certainly seems to be the culprit. I am running a 3560G and using it as DHCP and to do V LAN routing (Geiger protocol). I have 10 pools configured with a few static addresses per pool. Now to get down to the problem. I have a computer (and this problem seems to be a gremlin as it changes what computer is affected quite often) that will connect, get its IP, immediately disconnect, then send out a DHCP req again. The computer has a static assignment in the pool, and for the brief second that it connects, it gets the right address. If i move the computer to another v lan, all works right. If i delete the static entry it will get an address in the right v lan no problem. The command i have been using to add static entries is:
address xxx.xxx.xxx.xxx client-id 01xx.xxxx.xxxx.xx
That seems to have been working on all my static routes except for a bank of computers in vlan3. I have went as far as to delete the pool and recreate it, heck i even recreated the v lan and i am still having issues. Below are some snippets of the running config for review.
The DHCP Pool for the affected LAN:
ip dhcp pool Dev3
network 192.168.3.0 255.255.255.0
boot file bootx86wdsnbp.com
next-server 192.168.1.78
dns- server 192.168.1.8 192.168.1.78

We have 2x WS-C3560X-48 with the 10Gb SFP C3KX-NM-10G module.I want to use the 10Gb SFP (with a redundant 1Gb link) between each of the switches.Below is the configuration what I think I should use. Is this correct?
SWITCH1
int TE1/1
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode active
[code]....
We also want to utilise Link Agrrigation for the servers that attach to the switch. Would this config be correct?
port-channel load-balance src-ip
int range x
switchport mode access
switchport access vlan 1 (They are all on the default vlan)
spanning-tree portfast
channel-group x mode active
(Then I would configure the LACP config on the server) Is there anything I am missing?

Scenario: Two buildings connected with a private leased fiber line, so it does operate as a LAN. There are several subnets and everyone at both buildings needs to be able to access all subnets. However the physical machines on those subnets are building specific:
-Building 1: 10.2.0.0/24 (vlan20), 10.4.0.0/24 (vlan40), Internet connection
-Building 2: 10.1.0.0/24 (vlan10), 10.3.0.0/24 (vlan30)
The majority of the traffic between the subnets is specific to the buildings as well (i.e. most of the traffic is between 10.1 and 10.3 or 10.2 and 10.4).
Currently I have a Catalyst 3560 at Building 1 operating as the single "core" L3 router (and then a variety of switches connected to that). I have another 3560 at Building 2 that I'd like to turn in to the "master" L3 router for the two subnets primarily used by Building 2. In other words, make it so traffic from 10.1 to 10.3 doesn't have to run to building 1 just to get back to building 2.
I've got a basic knowledge of adding VLANs, VLAN interfaces and a static routes. The part that I'm getting confused on is that the Building 1 core router needs to make its default route to the firewall (and on to the internet) but "know" that traffic on vlans 10 and 30 gets sent across the fiber line to the other router. So I'm assuming this gets done with some combination of vlan definitions, vlan interfaces and static ip routes on each router.

i have a strange issue with an HSRP Setup. I have two (S1+S2) 3560 as Core/Distribution Layer. Inter-vlan routing are enabled on both Switches. S1 and S2 are connected with an ether channel over four fibre ports. S3 -S5 are the (L2) access layer.
Gi0/1 on S1 and S2 are L3 ports, connect to a Linux Firewall.
HSRP is enabled, S1 is the active router and the STP root bridge.
But, my monitoring via cacti show me, that the Gi0/1 on S2 is active, too! But it should not be active? Only if S1 fails, should S2 the active switch.A client from the access ports on S3 - 5 gets traffic from the Internet via Gi0/1 from S2. Gi0/1 on S1 is active too, but will send mostly traffic to the Internet. Why is S2 active and why route it traffic from the Internet to the client?

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 ?

Hardware to be used:
1. 2 catalyst 3560 switches
2. all connect to a sonic wall router
I have two companies that work in the same office space. I need to keep these companies seperate on their own vlan. They will however need to share the phone system.(Packet tracer file uploaded to give those who have the time to see what I put together.) [code]

I'm in the process of configuring QOS on a 3560 routing switch in a GOLD, SILVER, BRONZE priority type scenario.
Firstly, I understand that this config will add a tag of "precedence 5" to a packet if it matches the "ACL_QOS_GOLD_In" access list. Question is does the router see this "precedence 5" tag and then sets the priority, or am I missing something in my config where at present it just sees the "precedence 5" and doesn’t act on it ?
Secondly, Since the "precedence 5" tag has already been added to the packets, do downstream routers see this tag and act accordingly or so I need to configure those is well ? [code]
