Cisco Switching/Routing :: 3560E / Routing Between 2 VLans On Same Device?
Feb 19, 2012
I have a 3560E with 2 vlans that I want to route between. one device with 2 vlans and route between.Interfaces are configured as such:
int g0/11
switchport mode access
switchport access vlan 10
int g0/12
switchport mode access
switchport access vlan 11
[code]...
Laptops on each port with 10.10.10.2 and 10.10.11.2 configured on them. I can ping from 10.10.10.2 to 10.10.11.1, but not to 10.10.11.2.What do I have to configure to be able to get the 2 laptops to talk to each other?

3945 is running c3900e-universalk9-mz.SPA.151-4.M2
3560e is running c3560e-universalk9-mz.150-1.SE
I've got brand new 3945's with onboard 16-port 3560e switches. On the first power up I see that there are several new vlans added that appear to be default vlans..
vlan 2 name fst2
vlan 3 name fst3
vlan 4 name fst4
vlan 5 name fst5
vlan 6 name fst6
vlan 20 name VLAN0020
vlan 21 name VLAN0021
vlan 22 name VLAN0022
vlan 23 name VLAN0023
vlan 99 name VLAN0099
I deleted the vlan.dat and reloaded the switch but these vlans come back. What these vlans are intended for and is there a better way to get rid of them? What does "fst" stand for?

We have two Cisco 3560E layer 3 switches at the core of our network. The switches are configured as an HSRP pair and the clients on our network point to the HSRP address as their default gateway. So if CORE-A dies, then CORE-B will pick up the address and the default route for the clients will continue to be available.We also need to specify a few static routes on the core switch to allow us to get to specific networks. Is there a way to do this so that the routes failover in the same way that the default gateway does?

I have a Cisco SG200 26 Port Switch, 2 Cisco WAP4410N Access points, and a VLAN aware Router. I have created 4 VLAN's. For the sake of this conversation lets call them.
98 - Intel Vpro
99 - Management
100 - General
101 - Guest
The Access points are capable of doing V LAN tagging so I plan on having them tag a guest network as V LAN 101. That can get sent to the V LAN aware router and out. No problem. I have some devices, or management pages that I don't want accessible from the general network. (Intel V pro KVM, Remote Management Cards, AP Config Menus, Switch config menu...) . I need to be able to take a V LAN unaware device, plug it into port 1, and have it communicate with V LAN 98, 99 and 100.

I have a few 3560E running Ver 12.2(50)se2. Can these boxes be configured to run VRF. I see a "sho IP VRF" option, but I do not see it available when under config t. Do I need to do a IOS upgrade to be able to configure VRF?

I upgraded four 3560E, 12.2(44) to 12.2(55)SEThree 3560 works fine, the last one stops after 17-18 seconds with a solid green LED. I cant get into ROMmon, the switch doesn't boot up. its like "dead but still alive"
My TS:
1: Removed all SFPs.
2: Reset PSU and fan modules.
3: Replace PSU and fan modules.
4: Try to get into ROMmon.(pushing mode button and break seq.)
Startup LED:0-1 seconds: SYST: Amber RPS: Amber STAT: Green DUPLEX: Green SPEED: Green
1-17 seconds SYST: Blinking Green RPS: OFF STAT: OFF DUPLEX: OFF SPEED: OFF
18 s--> (only testet up to one hour) SYST: Solid Green RPS: OFF STAT: OFF DUPLEX: OFF SPEED: OFF
A working 3560EStartup LED information. If I compare a working switch with the faulty switch I can see about 18 seconds into bootingSYST change very fast from green to amber and continues with booting,this doesnt happened on the faulty switch (solid green 18 seconds). Pushing MODE button, doesn't get me in to ROMmon, this works for all the other switches.On a normal 3560 it takes around 40 seconds before I get in to ROMmon. With this faulty switch it stops after 18 seconds(solid green) and it doesnt respond.

recently a Cisco 3560E switch went down due to a power surge. the switch is getting power but i am only seeing the below message continously. it is keep on rebooting. i try to reset to factory settings/ safe boot nothing worked. is there any way i can bring the switch up or it is hardware failure.Using driver version 1 for media type 2Base ethernet MAC Address: 00:23:33:af:1b:00Xmodem file system is available.The password-recovery mechanism is enabled.Using driver version 1 for media type 2Base ethernet MAC Address: 00:23:33:af:1b:00Xmodem file system is available.The password-recovery mechanism is enabled.

I have a cisco 3560E switch setup with LACP, when using LACP i receive alot of packet loss / output drops
When a ping from the server behind LACP:
--- google.com ping statistics ---
44 packets transmitted, 39 received, 11% packet loss, time 42990ms
what would cause this packet loss with lacp?
some output from the switch:
Port-channel12 is up, line protocol is up (connected)
Hardware is EtherChannel, address is d0d0.fd58.7390 (bia d0d0.fd58.7390)

I'm trying to configure "IP PIM SPARSE-MODE" command on a vlan interface on a 3560E switch but it doesn't give me the option to do this. The only option available is ip pim passive. What would cause this ? On the same switch a physical interface is already configured with IP PIM SPARSE-MODE.

I recently upgraded a remote site of mine to IOS 15-2.SE ipbasek9 on 3 3560E series switches. On switch number 2 I have 5 VG224's running (vg224-i6k9s- m) 12.4(22)T3. After the switches reloaded the VG224's dropped their connection. After doing all basic troubleshooting I reloaded the 12.2 (58)SE2 ipbasek9 image back on to the 3560E's and the VG224's reconnected immediately after reload and all phones registered.
Is the problem a licensing issue with the 15.x IOS on the 3560's or do I need to upgrade the VG224's to IOS 15.x as well for them to connect and operate via the 3560e switch running 15-2?

I have 3560e which doesn't appear to be passing igmp traffic to the upstream router
PC1 ----------- ASA ------------ PC2--------- 3560e ----------- 3825 -------------------- WAN --------------------- Router ------------- Server
My ASA runs SMR, has an igmp forward interface outside command on the inside and has a trunk port to the 3560e (V lans 32 & 48).PC2 is a test pc on the 3560e on vlan32. 3825 is my ISPs router on vlan32.
- if i try to access the stream from PC2 it works.
- if i try to access the stream from PC1, i see the igmp join leave my ASA onto the 3560E (i've captured on the 3560e's link to the ASA).
I've also captured on the ASA and i can see the igmp packet leave the outside interface but the join doesn't reach the 3825 (i've captured on the 3560e port facing the router and there is no join being forwarded).the switch is running in layer 2, 12.2(35r)SE1.

We have a Site that is connected via Wireless Bridge to the Main Site, the site is on separate VLAN with Cisco 3560 switch. The main site has 6509 swith. Configuration as per attached diagram. We are connecting a fiber between the remote and the main site and adding a 3560E switch at the remote site, however we would like to keep the wireless connection as a backup in case the fiber is severed the wireless will be availble. Attached diagram shows detailed cofiguration. I would like to know what should I change to make this working. STP is enabled on all switches.

We are receiving a large amount of output drops on 4 interfaces that connect to microwave wireless.This is playing up with our Management system. Saw a bug report but that was for 3750, not the IOS version but was a similar issue. [code] The output errors tend to happen at the same time. All ports are trunks however there are other trunks on the switch that are not having these issues. [code]

upgrading our small office network. We currently have about 75 employees with probably 125 devices on the network. I'd like to create about 10 vlans for the different departments and then configure intervlan routing as needed. Currently we have all unmanaged switches and it's just a huge broadcast storm on the network. We are upgrading our Cisco 800 router to an ASA5505 sec. Plus license. I need some recommendations on switches. Of course, this needs to be done as cheap as possible.... Is there a way to use the ASA to configure all the vlans and intervlan routing and access lists and use a cheaper switch to provide the access layer to hosts?

I have the following config using a Cisco 1921. I am trying to get devices on the the native VLAN to get internet access via the gateway x.x.x.73.Any thing being routed from the other Vlans 15/20/30 can get access, but nothing from an internal IP address. Is there something I am missing.
The Xs replace the same 3 octets for each interface.I am trying to route from VLANs 15/20/30 to see VLAN 5. I have tried a few things, in terms of adding extra ip routes, but can't get anything to work. Each of those Vlans have another router on the other side of them, which I have also tried adding ip routes too, but nothing. One of the routers (Vlan15 is a Draytek 2830). [code]

I have purchased these two switches from ebay as a test lab, I plan to connect them up via a gigastack modulecable and enable ip routing on the c3550 and vlans to talk to each other.
I'm very much a procurve person and really need to get into the cisco switching.I will want to trunklacp between the switches - whats the process is setting that up on cisco switches?

I am setting up a vm environment for a customer in my lab off site. I have two stacked 3750-x switches, a san, and threes UCS c220 M3S servers for hosts. I am trying to separate the lan traffic, san iscsi traffic, and san management traffic using vlans. The problem is i'm unable to communicate cross vlan with my current config, which I have attached to this post. The only noteworthy things in my conifg is that the ip route 0.0.0.0 0.0.0.0 192.168.83.6 is referring to a switch stack they have on site, that I will connect this stack to using the first two trunk ports on each switch, that I do not have here in the lab. I don't want to cause any confusion in why I have things set a certain way.

I have tried to test copy tftp: numerous time with no success. I believe the reason it is failing is my laptop to Ethernet port is in vlan 62 and the tftp process operates in a different IP space.I am using gig 7/1 and configuring my laptop nic for x.x.x.254 mask 255.255.255.0. I can ping from laptop to gateway) and I can ping from the switch to my laptop using ping vrf production x.x.x.254. Can you tell me what vlan I need to set my laptop connection in or if there is something else I need to change to make tftp work on vlan62?Does TFTP only work in vlan1 or can it be changed?

I recently set up a Cisco 881 to cover a small business network. The router is currently set up and working as expected. We recently decided to move to VoIP phones and here is where I'm running into some issues.
First an overview: We run a network with a cable internet WAN connection, this connection is DHCP, however we have a static IP through our ISP. We also have a block of 30 additional IP addresses for one to one mapping as we need them. The new VoIP system is being run over T1 lines throughout the township (we are a municipal organization) and the VoIP system is being run to about 5 buildings in the township.
This brings me to the topic of VLANs. As the phone engineer explained it to me, there is a network set up over the T1 that allows the VoIP equipment to talk to one another and operates all of the VoIP phones on one network. The equipment that is being installed at our building connects to the network over the T1 and "talks" to the other equipment on the network. The engineer wants to create a VLAN and run it on ports fa1 and fa2, with the fa2 port being connected to the actual "MPLS" (their term) that connects to the T1 and into the cloud, and the fa1 port connected to the internal phone switch.
TLDR; The problem is this: When we attempt to set up the VLAN on ports fa1 and fa2, we have no connectivity with the other units in the external VoIP cloud. Pinging while directly connected to the "MPLS" yields successful pings, while pinging from the router with the "MPLS" connected to fa2 yields failures. I'm going to post the running config below, I feel like what we're doing should be working. I asked around about subinterfacing, but others seemed to think this was not necessary.

I am working on getting my CCNP. The first exam I plan to take is the switching test BCMSN 642-812. Using the 4th Edition Self-Study Guide from Froom, Subraniaman, and Frahim.In Ch-4 it talks about End-to-End VLANs and Local VLANs. I read that section 4 or 5 times and still did not understand the difference between them two.I know one spans across the entire network and the other is local. What do they exactly mean by that?

I have the need to filter multicast between vlans as described below. PIM Sparse-Mode is being utilized for this multicast network and changing any Vlan to PIM Dense mode is not an option.
- Vlan 217 and Vlan 4 should not be communicating on mcast with any other vlan, including eachother (each vlan isolated).
-Vlan 64 and Vlan 80 are able to communicate witch each other on mcast but not with any other vlans (isolated vlan group).
-All other vlans can communicate mcast freely.
What I've created thus far is below. It does not appear to be the most elegant solution and would be difficult for the administrators to adjust as new requirements come along. Yes, I will be adding the appropriate link-local multicast addresses so as to not break routing and other dependent technologies.
ip access-list ext ANY_CONN
permit ip any any
ip access-list ext MCAST_INTRA_217
permit ip 224.0.0.0 15.255.255.255 133.106.197.32 255.255.224.0
permit ip 133.106.197.32 255.255.224.0 224.0.0.0 15.255.255.255

We have the need to create a large number of VLANs on one of our networks. We're talking about 60! These will all terminate on a pair of 6509-E switches (building core). We use MSTP as a standard on our network so I'm going to stick with that so that we can dramatically reduce the number of STP instances needed. However, regarding the SVIs (default gateways) is there any reason why creating 60 of these guys would be considerd a big no-no? Or would you expect the 6509s to deal with them like a boss?

I need to set up a VLAN. We just bought the SG500x switches and we need to create several VLANs.
So for example:
192.168.1.x --> Vlan 1
192.168.2.x --> Vlan 2
192.168.3.x --> Vlan 3
What I would like to know is how do I come about setting this up and do I have to do something with my DHCP server to allow this to happen?
