Cisco WAN :: VLAN On 2960 And 3560 Switches
Apr 10, 2011
We had a new building thats gone up and complete now and we're trying to get a ip phone working down that end of the school on a vlan. We seem to be having trouble with the VLAN going through on the 2960 switch but it works fine on our core 3560 switch.
There looks like a slight variation in the config of the switches, the 3560 switch supports the "switchport trunk encapsulation dot1q" command on the interface where as the 2960 doesn't support the "switchport trunk encapsulation dot1q". Is this why the vlan is working on the 3560 and not the 2960, or is it something else?
Both switches are using the 12.2 IOS
Heres the trunk port configured on the 3560 going down to the new building and connecting into the 2960 with a 1gbit fiber link
interface GigabitEthernet1/2 description 3560X Port UpLink as Trunk Mode switchport trunk encapsulation dot1q switchport mode trunk udld port storm-control broadcast level 60.00 spanning-tree guard root
Heres the trunk port configured on the 3560 going to a Linksys switch which then connects to the DHCP server (The other end of the 3560 is also configued as trunk)
interface GigabitEthernet0/6 description Edge Switch port for clients switchport trunk encapsulation dot1q switchport mode trunk spanning-tree portfast
Heres the working vlan port on the 3560, the ip phone is able to get an ip and ring all other phones etc
interface GigabitEthernet0/7 description Edge Switch port for clients switchport access vlan 2 switchport mode access spanning-tree portfast
Ok now heres the config for the 2960
Heres the trunk port configured on the 2960 going back upto the 3560 switch
interface GigabitEthernet1/0/25 description Port UpLink as Trunk Mode switchport mode trunk udld port storm-control broadcast level 60.00
Heres the access port configured on the 2960 which isn't passing on vlan information. Is there another command i need to use to enable encapsulation as dot1q?
interface GigabitEthernet1/0/19 description Edge Switch port for clients
switchport access vlan 2 switchport mode access spanning-tree portfast

When did this wonderful feature get introduced? Is it going to moved down to the 3560s/2960s type switches?

I am implementing QoS on our MPLS network. Our environment exists of a mix of Cisco 2960 and 3560 switches. The IPT system is Avaya CM with Avaya phones.The WAN network is a MPLS network.Ports are configured for access and voice vlan (no trunking), one vlan for voice, one for data (vlan 1 is disabled).I dont have Qos coonfigured on LAN just wanted to configure on WAN Router where my Mpls link is connected.I have 45 Mb Mpls links on all sites connected to each other.
I have multiple sites connected via MPLS and i have control at both sides.Current config is mentioned below in which DSCP marking is not done for signaling. What is the best config with example.Current Config on all Cisco Router where MPLS link is terminated at all sites. [code]

I have more than 20 Cisco switches in my office which is basically a soap manufacturing factory. The switches include Cisco 2950, 2960, 3560, 3750 etc. We have routers also which include 2821, 2951 etc. We also have Cisco WLC 2125 and LAP 1262 series. Sometimes all these devices management comes very tough to us.
We need to log on to different devices for troubleshooting/network management which sometimes becomes very tough to us. So I wonder if there any Cisco applications or tools by which we can centrally manage all these devices.

We have two Cisco switches with one 3560 and one 3750 we have created a new Vlan 4 with IP 10.1.3.x 255.255.255.0 - no shut then assigne to gi 2/0/46 on the 3560 Vlan 4 ip address 10.1.3.x 255.255.255.0 no shut then assign to FA0/45. All interfaces are up up along with the Vlan up up, we can ping the local IP address bu not able to pint the other switch.

How can I configure Cisco 200 (SG200-08P) to learn Voice VLAN and CoS/DSCP from upstreamCatalyst 2960?
The Cat 2960 is today used together with LLDP-MED to announce config to Aastra IP Telephones. In some cases I need to use a small switch inbetween and plan to use the Cisco SG200-08P for this. However, I would like to avoid manual config of the Cisco 200 switch.

I have a number of class-'c's as a hand-off from my data center fiber to my 2960, which then sprawls the racks with about many 2950 switches, mostly 20 machines per switch. To allow machines on one 2950 to push data to another 2950 without routing back to my ISP's router(which costs money for bandwidth) isn't is possible to trunk one port on each 2950 to another 2950 and adding a addititional vlan8 to them. Then data jumps from 2950 to 2950 without going back to the 2960 or mainly not going back to my ISP's router. Is this the correct way to accoplish this with extra vlan and trunking the 2950's to each other or am I looking at this all wrong?

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?

Yesterday Cisco released IOS 15 code into the wild for the 2960 and 3560/3750 families but the link to the release notes is not working. Because I already have a whole bunch of 4500/Sup7's running IOS 15 I am thinking about taking the plunge with 30 3750-X's I have on order but want to review the release notes first. where they might be hiding?

As per my attached diagram, I have three switches (Cat 3560-E and couple of Cat 2960-G)
Each PC is on different vlan
PC -1 on vlan 100
PC-2 on vlan 200
I need to connect PC-1 and PC-2 to the server. Server has no fixed vlan and can be changed.
Restrictions:
1) can’t change PCs vlan assignment.
2) can’t add 2nd NIC in the server.
I’ve tried private vlan but it requires separate physical ports for host and/or community vlan and somehow it did not work. I could be wrong Trunking using dot1q enabled on port 2 on all switches and connection works fine (server to PC-1 or server to PC-2) by enabling switchport access vlan 100 or switchport access vlan 200. However I need port 5 on switch-1 to respond to vlan 100 and 200.

I would like to test the possibility to reload devices via SNMP for new switches like 2960, 3560 and so on.I know that the command "snmp-server system-shutdown" has to be configured, then I need to send the set query to the device via SNMP.
I have found on the net the OID 1.3.6.1.4.1.9.2.9.9.0 but it belongs to an old MIB and doesn't seem to work with new switch models.

I want to implement port-based and MAC-based in these two switches: 2960 & 3560 (both of them have this IOS version: 12.2(55)SE1). And I haven't found a way to implement both of them at the same time. This is what I got:
ip dhcp use subscriber-id client-id
ip dhcp subscriber-id interface-name
ip dhcp excluded-address 192.168.0.0 192.168.0.2
ip dhcp excluded-address 192.168.0.251 192.168.0.255
[code]....
With this configuration I can use port-based, but not MAC based. If I remove the first two lines and change the last line for this one:
address 192.168.0.7 client-id 0112.ae1d.af58.60
Then, the computer with that MAC address got the correct IP, but then the port-based doesn't work. Also, I got this line in the interface what I want to use MAC-based:
ip dhcp server use subscriber-id client-id

We have quite a few 3560 & 2960 on our edge network - what I have been looking at was to access switches via web-interface i.e. web-browser. Only problem with this is it always gives you access on privilige level 15 which is not ideal as not all who we decide to give access to these switches will be admin and allowed to configure these swicthes - In the 3560/2960 data-sheet states:
"Alternatively, a local username and password database can be configured on the switch itself. Fifteen levels of authorization on the switch console and two levels on the Web-based management interface provide the ability to give different levels of configuration capabilities to different administrators"
Where as there is no mention of how to configure these two levels of Web-based management in the configuration guide.

We are trying to config vlan 10 for data and vlan 20 for voice on the same port - port 1 of swtich SF300-24P to run both data and voice on different vlans.Do I have to add vlan 10 as an untagged vlan to port 1 and add vlan 20 as an tagged vlan to port 1?If I do not want to assign the native vlan 1 to port 1, how can I remove it ? The GUI page - assign VLAN to port does not allow to remove it.Aslo, what mode shall I set up on port 1? General, trunk or access ?

As per the attached diagram: How do I configure the 2 ports on the 3560 (Ports 6 & 7) and the connected ports on each of the 2960 switches (Port 25) to provide redundancy.
If the up link from Switch A dies then I need the traffic to flow through the trunk and utilize the up link on Switch B with minimal delay (milliseconds).

I have a Cisco 3560 running as a Level3 device in my network running 10 V LANs and routing between most of them (nothing complex with ACLs) and running spanning-tree mode pvst. The main network is run on a net gear GS748TPS stack of three switches running MSTP.
I have just bought an additional 3560 and a 2960 to plug in. I have set them up with IP addresses and then plugged them into the net gear. This brought the whole network down until I unplugged the new switches.
I have confirmed the IP addresses aren't duplicated and that DHCP is not running on the switches so I can only assume it's something to do with DHCP. I cannot afford for the network to go offline again, so is there anything I should check? Am I running incompatible spanning tree methods between the net gear and Cisco devices?

I have some problem in my small network.I have 2 SF-300 48 port switches and connected to 847 router for intervlan routing. I configure 7 vlan in SW1 and uplink to SW2 with trunkport.
The problem is that if i used default gateway for users ip address of interface (vlan interface) is ok. I bring two adsl modem and connected to vlan1 and vlan2 for internet access. When i connected this two modem vlan 1 and vlan 2 are not going to access other vlan 3,4,5,6,7 and wise versa.
vlan1 users getting default gateway from adsl modem ip, how i can permit this two vlan should to access other vlan 3,4,5,6,7 and 3,4,5,6,7 should access to internet also.

Is it possible with a 3560 to block all traffic to a certain vlan except for one or two IP addresses? Create an ACL or something? We have a vlan for voice calls (SIP) and we are getting a lot of scnas that are making the phones ring and such, and I think we can stop this if we only allow traffic onto the vlan from the IP's the SIP traffic is SUPPOSED to be coming from.

I have a 2960S switch and nine (9) 300 switches. I have three VLANs configured on them, data, voice and management. Each 300 has unique data and ovice VLANs corresponding to their locations. All of the 300 switches connect to the 2960 in a hub and spoke network topology via 802.1q trunks. I can access devices between switches on the data and voice VLANs fine from any other switch. My issue is that from any 300 switch I can access the 2960 management VLAN interface without a problem, but I can not access the 300 switch management VLAN that I am connected to from the CLI. I do not use the GUI at all for management.
