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.

In 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.
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?

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

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 have 2 pairs of Nexus 5000 units (pair 1 and pair 2). A pair consists of 2 Nexus 5000 (A and B) connected to each other via a VPC containing 2 ports ie P1-5KA -- P1-5KB (vpc domain 6) and P2-5KA -- P2-5KB (vpc domain 10) [code] Hsrp exists between all four with a virtual address of 10.18.136.1. P1-5KA is the Active with P1-5KB as Standby.
I can ping between the four using their SVI addresses. I am unable to ping the HSRP virtual address .1 from P2-5KA or P2-5KB.I can ping ok only if I shut the VPC between P2-5KA or P2-5KB or define another mac address under the HSRP config other than the system default. IP Packet debugs show that ping sourced from P2-5KB to P1-5KA loop between P2-5KA -- P2-5KB. Pings sourced from P2-5KA to P1-5KA are transmitted but none of the 4 device debugs show a receive. both peer-gateway and delay restore 120 have been configured under all vpc domains and all units rebooted.
For 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.
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.

Firewall: ASA 5510
Switch: Linksys SRW2048
Physical topology: PC - > VLAN99 - > SRW2048 - trunk - > ASA5510
Switch Setup:
I've been tasked with breaking up a network that has run out of IP's, and have decided to use VLANs to accomplish this. I have to use an ASA5510 to accomplish all the routing between hosts in different VLANs.Port 48 is trunked to the ASA eth0/0 interface, with VLAN 99 and VLAN 20 tagging packets, VLAN 1 Untagged. Hosts hooked up to appropriate ports on Switch.
I am a complete newbie to Cisco equipment. So far I've been able to figure out how to do most of what I needed by using the ASDM but I have run into something that is a little more complicated that just opening a port. We currently have a connection to our remote site. This site has a T1 internet connection. Our connection is a site to site VPN with an ASA-5510 on this end and a ASA-5505 on the other.
We are upgrading this connection to a 75mbit hybrid microwave/fiber link. The provider is going to hand it off to us as an untagged VLAN. We made the decision to route all of the remote site's internet access through this location as to avoid having to split off part of the bandwidth of this link to dedicate to internet access.........
Have multiple Catalyst 2960S switches, Cisco 2911 router and ASA 5510 firewall.
On the router have subinterfaces created for the VLAN's Int FA0.0/41 for wirless VLAN setup with IP 10.10.41.100 Int FA0.0/60 for new Voice VLAN setup with IP 10.10.60.100 Internal network is 10.10.10.0/24 and LAN IP of router is 10.10.10.100 Have default route setup to push traffic from the router to the firewall ip route 0.0.0.0 0.0.0.0 10.10.10.251
On the firewall have added the new VLAN 10 (10.10.60.0) to the network object-group Have configured route inside command route 10.10.60.0 255.255.255.0 10.10.10.100 1 Have also added the NAT command nat (inside) 1 10.10.60.0 255.255.255.0
On the 2960 I have my laptop connected to port 45 and I have it configured as follows switchport mode access switchport access vlan 10
I assign my computer a static IP address of 10.10.60.84/255.255.255.0/10.10.60.100 with 10.10.10.11 as DNS server. When I do this, I can ping anything on the 10.10.60.0 network, I can ping anythign on the LAN 10.10.10.0 network. I am able to connect MSN messenger, I am able to do NSLOOKUP and get outside IP addresses to resolve. I am unable to browse the Internet though. I am not sure where the problem is at though. It doesn't make sense to me, as it is setup the same way as VLAN 41 which is the wireless network, and when users connect to that, they get out to the Internet with no issues.
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?
My first question is I have an access layer switch which is a single VLAN and I am trunking that VLAN to a distribution layer switch, I can ping the gateway on the distribution layer switch for THAT VLAN, But cannot ping the gateway address for the second VLAN I have on the distribution layer switch. I know it is simple, But I have forgotten and just need a push
Also I have a third VLAN set to route traffic not bound for those 2 VLANs out to a router is the statement "ip route 0.0.0.0 0.0.0.0 172.16.252.2" good enough and do I actually need to create a VLAN for that traffic? and if so, is an access switchport the best option?
I have no router inplace that can do trunking (5505 basic license )I have 2 VLANS 10 Data 20 voice I have given both VALNs IPs lets say
-VLAN10 192.168.1.1
-VLAN20 192.168.2.1
Enabled IP routing and set the router as the gateway of last resort.Now becuase the L3 switchis doing the routing I have had to set the default gateway as the VLAN IPs. So PCs on VLAN10 get a gateway of 192.168.1.1 and phones on VLAN20 get a gateway of 192.168.2.1
Any real downside to having the 3560 doing the VLAN routing, is this the "correct "way to do things in the event I don't have a trunkable router?
I have two networks at two sites with a dot1q trunk between the two L3 switches at both sites (no routers involved)
SITE A - Cisco 3750 L3 - VLAN ID 50
10.10.50.0/24
SITE B - Cisco 3750 L3 - VLAN ID 50
10.20.50.0/24
I would like to extend the SITE A VLAN to SITE B so that I can move hosts from SITE A to SITE B without needing to change their IP address but the vlan ID is already in use. Obviously the easy solution is to change the VLAN ID for one or other of the sites but both sites contain hosts that run 24/7. Is there a way to join two VLANs with different IDs together.So for example I create a new VLAN 60 at SITE B and associate it with VLAN 50 at SITE A.
i need to solves this little problem on 2960S lan BASE but i dont know if it is possible.
Uplink port config for gi 1/0/28 is:
switchport mode trunk
switchport trunk alloved vlan 10,11
but on interface gi 1/0/1 i want to have data from vlan 10 tagged as VLAN 20.
At this time i have solved this issue very primitively
I have set up gi 1/0/2 as int mode acces, acces vlan 20 and i have connected gi 1/0/2 with gi 1/0/3 with eth cable. int gi 1/0/3 is switchpor mode acces, switchport acces vlan 10
I have a 3750G switch in my production network that only has VLAN 1 on it. All ports are in a default state and VLAN 1 is disabled. The switch is passing traffic but shouldn't having the default VLAN shut down cause the ports not to pass traffic? If I start to create VLANs will that cause the switch to stop passing traffic?
