I have a 3560 switch with the following ports config [code] I would like to use theses ports on a different vlan to connect 4 pc's to them. Can I just remove them from the vlan, remove the trunk switchport and set up on the vlan i want them on with no trunking?
View 5 RepliesFor many years we've had the following vlan and port security config on our 3560s: [code] This has worked great on 12.2(37)SE1, 12.2(40)SE and 12.2(46)SE. However since 12.2(50)SE, and I've tried all the versions since then, we have a problem with 7900 phones and ATA186s taking upwards of 20 minutes before they can get a valid IP number.The problem on the newer IOSes seems to be related to the inactivity aging.On the older IOS versions the mac address of the voice device appears on the voice vlan straight away.
On the newer IOS versions the mac address of the voice device appears on the DATA vlan and seems to be stuck there until the inactivity aging removes it. It then gets re-learned, sometimes on the voice vlan, and sometimes on the data vlan. If you're unlucky and it gets re-learned on the data vlan you've got to wait until the inactivity time ages the address out again. Repeat until the mac address eventually gets learned on the voice vlan. I don't want to be stuck on 12.2(46)SE forever.
Any way to test in a lab what would happen if a tech mistakingly added "switchport voice vlan XX" to a trunk port? I am try to do some RCA on an issue and this has been identified as a possible cause by one of my techs.
The config is Switch1------Switch2--------Switch3 Each interswitch connection is configured as a dot1q trunk with all vlans allowed. The link between switch2 and 3 is where switchport voice vlan 10 was added. Switch1 is a 3750 and 2/3 are 3560's.
I'm new to networking and was looking for some assistance. First off im using packet tracer to diagram my senario as I will be receiving my equipment next week to deploy.
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]
Between our hosting and a customer we have an extended vlan, traveling on a fiber, between two cisco 3560 switches.The thing is, that we want to create one or more vlans inside that extended vlan, in some way if possible?
View 3 Replies View RelatedI have 2 SG300 switches, in layer3 mode, lag'd together for high availability, serving 2 Dell R815's and a Dell Equallogic 4100 for virtualisation. I have setup a number of vlan's, network traffic, mgmnt traffic, iScsi, vMotion etc and they seem to work.
However, Equallogic unit suddenly became unavailable to view for managment yet maintained iscsi traffic for the servers ok. After much head scratching, noticed that one of my SG300's had the vlan ports assigned to various vlans had *automagically* changed there assignment, ie tagged changed to excluded, but only for one of the iscsi traffic connections and the mgmnt port, both coming from the Equallogic, the other iscsi continued its assignment fine. The other SG300 hasn't changed. Guaranteee no one has been into change it and no changes have been made to Dell servers or Equallogic.
Q. Is there any circumstance where the switch can change the port setup itself? or is there any external circumstance that would trigger that change either?
This has now occured twice. The setup is running as a test lab, not in production until all setup is complete, then it will replace our existing harware.
I am having trouble after creating a management vlan (99) on a 3550 switch.I have configured the vlan (99) and given it an IP (192.168.1.100) and a default gateway (my router address - 192.168.1.99).I can ping to the switch from a PC and vice versa. The management VLAN IP is fine but now I cannot ping to the router from either the PC or the switch.It seems that just by adding VLAN 99 with it's own IP address has now prevented pings from the switch/ PC to the router ?Due to the fact that I have created a new switch management VLAN with an IP, does this mean I have set up the router as a 'router on a stick' scenario ? [code]
View 4 Replies View RelatedI have an all gigE 3560. I don't use the management FE0 port on the back. I was thinking to use that for a 100Mbps WAN connection.
Seems to work just fine when I plugged in an test. But I am not routing across that link yet as I still need to setup the far end.
Is there any reason this would not work? I would like to not burn a gig port if the max throughput of the circuit is 100Mbps.
Is there any way to check if this VLAN is used by somedevice?

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?
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.

View 1 Replies View RelatedIn my lab setup i configured Cisco 3560 switch.
-VLAN 20 and VLAN 30 i configured.
-VLAN 20 interface IP : 192.168.20.1/24
-VLAN 30 interface IP : 192.168.30.1/24.
Inter-vlan communication is happening fine. For testing for purpose i configured extended ACLs.i want stop communication from VLAN 30 to VLAN 20 but not vice-versa. If i ping from one of the IP VLAN 20 to one of the ip of VLAN 30, i was gettng Requested time out. And if i ping from one of the IP VLAN 20 to VLAN 30 interface IP, i was able get pinging.From VLAN 30 to VLAN 20, i was getting destination host unreachable from VLAN 30 ip( Its fine as its my requirement)So, solution needed to communicate from VLAN 20 to VLAN 30.
Probably an easy fix but something's weird in my config. I am setting up a new network, so this is not production, Routed environment, down to the access layer using 3560-x l3 switches.

I'm configuring two etherchannel groups (2 ports in each) on a 3560 switch. I need to trunk multiple vlans over each channel group.
I created the vlan trunks and allowed vlans on each physical interface. I notice that I can also configure the vlan trunks on the port-channel interfaces that were created. Should I configure them under those interfaces, or leave them on the physical interfaces? Relevant config is below:
interface Port-channel1

interface Port-channel2

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.
View 2 Replies View RelatedI have a HP Procurve 5406 connected to a Cisco 3560 on a temporary cat5e connection and I have Mitel IP phones needing to go on the Cisco switch.Ive configured the HP Procurve port to TAGGING both VLAN 10 (data) and VLAN 20 (Voice). NO is selected for default VLAN 1.The Cisco is configured on the port with switchport encap dot1q and switchport mode trunk.
Ive configured an IP for interface VLAN 10 and i cannot ping it from across the network. The interfaces are up and happy. I have tried changing the VTP status from transparent to server (VTP pruning is off) ive tried setting allowed vlans 10,20. Still not a think. The worse thing is that i have a working Cisco switch with the HP procurve that i checked the config on and its the same! The only difference is that the media type is SX over SFP in that case.
p.s not that im at this stage yet but i initially configure the FastE ports as trunks with native vlans because i was using non-cisco phones. On a spare port i convigured the voice vlan 20 and i say on the mitel phone that it was looking on vlan20! I didnt expect that, i thought the Voice VLAN ID was carried on CDP enabled devices only.
I've set up my 3560 to do routing. Now, I'm looking for a way to apply acl restrictions to the vlan interface ip address itself.

View 8 Replies View RelatedI have a 3560 8 port switch. Int gi0/9 is trunked to another switch downstream. When I try to configure int gi0/10 to trunk to a switch upstream the interface on the switch goes down and I have to either reboot the switch or plug directly into the switch and telnet into it to turn off trunking on the interface. When I configure trunking on the interface on the upstream switch that connects to this interface the same happens on that switch. The upstream switch is a 3750 with 12 sfp ports. Several interfaces are trunking to other switches from this switch. Spanning tree is not configured on the 3750 at all , and is not configured on either gi0/10 or gi0/9 on the 3560. I was consoled into the 3560 during a reboot after the interface went down, a message came up that said something like "Spanning Tree returning gigabit ethernet 10 to constant state" Why would I get this message if spanning tree is not enabled on the gig ports on either end of the trunk? There is no loop to require spanning tree to shut down an interface. I have several other 3560's configured as I would like to configure this switch and they are trunking without issue.

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
I am using 3560.IP rouitng is being turned off on this.Curious to know if I will create etherchannel or port channel.I think etherchannel.Correct me if I am wrong.On connecting switches I have vlan10,20,30 to be allowed.I am sure I need to allow these all vlan in 10,20,30 which are on the trunk port on each side switch.Post that will add channel-port lacp and make it in active mode.Is that correct.This way traffic will be load-balanced/aggregated on minimum 2 ports who are the part of this.
