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]
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 ?

View 3 Replies View RelatedI 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.
We have 6509 VSS with FWSM Module and we have created two context on it, one is INTERNALL CONTEXT othe is EXTERNALL Context? We have spanned various VLANS in switches and FWSM context level. All VLAN Gateways are configured in context level.
Activity description : We had planned migration of these devices into a new Datacenter, it was a planned activity. During migration of devices from one Dc to a new DC we broke the VSS and kept the primary running and removed the secondary switch and migrated this secondary to new DC and powered this device ON in the new DC and checked all the config was very much fine but this device was OFF network as secondary was brought to new DC just to limit the downtime during the primary switch movement.
During the activity ( Primary switch movement )We powered off the Primary switch and mean time before shifting into new Data center We had brought up secondary switch which was already existing in the DC was put live in the network and it was working fine without any issues.
Later we had moved Primary into new data center and tried to put into VSS with the secondary , during this period the secondary device into went into RECOVERY MODE and primary device was not responding and devices went off network and immediatly we removed the VSL link and brought up primary into production network without secondary online in the network ( Without VSS just stand alone switch ) network started working, but bringing up the primary we found that some of the VLANS in the FWSM was deleted and some VLAN had misconfiguration ( example : say original VLAN ip 10.200.112.1 has become 10.300.13.1 ) also some of the access list as well as SVI was deleted making configuration mismatch.
Wanted to know while syncronization b/n primary and secondary switch in VSS if we pull out VSL link would create this type of issues.
I have set up 2 DHCP pools and 2 VLANs (1 *the native* for data / 1 VLAN for voice). When I use the command "switchport voice vlan 20" the port disapear from the show vlan brief list. When I use the "switchport access vlan 20" it shows up in the show vlan brief in the correct VLAN and gives the phone an IP. I assume that using the access instead of the voice is wrong and the phones would not configure correctly. But when I use the access the phone goes to the next step and tells me the TFTP files are not found. Why does the port disapear from the VLAN list?

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?

Everything is working fine except for 802.1x...I can get the 881 to authenticate things connected to it, but I don't have the options of guest-vlan or auth-fail vlan.Idea is if the users takes the router home and someone, either accidentally or on pupose, connects an unauthorized Laptop, they stay off the Corp network but can get to the internet still.I found this link on Cisco's site: [URL]That link shows them configuring a guest vlan right on the fa0-3 ports of an 881W.

I am trying to setup a L2tpv3 VLAN-to-VLAN tunnel.My setup has two Cisco 890 router with Cisco IOS Software version 15.0(1) M4. These routers are connected directly on FastEthernet port 8.
One linux machine is connected on FastEthernet port 0 on each router. The two linux machines are on same vlan. I am trying to establish a vlan-to-vlan tunnel between the routers and send traffic between the linux machines.
I followed the case study 11.4 from [URL] and configured the l2tp-class and pseudowire-class. However, the vlan interface configuration is different on 890 router.
I configured a vlan interface as follows.
(config)#vlan 200
(config)# interface FastEthernet 0
#shutdown
#switchport access vlan 200
(config)# interface vlan 200
I don't see the 'xconnect' command in this context. What's wrong with my configuration?
We have a low bandwith (15-20 Mbit/s) to the ASA from our Client vlan. If i connect the Client to the same vlan as the ASA is, the bandwith (90 Mbit/s) is good.
Here are the Layer 3 Design:
Client -> vlan 2 - Switch - vlan 7 -> vlan 1 - ASA 5505 -> ISP
The Layer 2 Design:
Client -> Gig2/0/13 - Switch - Gig4/0/43 -> Eth0/1 ASA5505 -> ISP
IP Address:
Client: 172.16.2.10Vlan2: 172.16.2.1Vlan7: 172.16.7.1ASA: 172.16.7.2
I assuming the switch has a problem with routing ?It is a stacked Switch with following members:
switch 1 provision ws-c3750g-12sswitch 2 provision ws-c3750g-24tsswitch 3 provision ws-c3750g-24tsswitch 4 provision ws-c3750x-48
And we have following error message in the log from the switch:
%PLATFORM_UCAST-4-PREFIX:
One or more specific prefixes could not be programmed into TCAM and are being covered by a less specific prefix, and the packets may be software forwarded I first get the idea that the switch is overloaded with router traffic. Thats why i assuming i have to check the sdm templates, but i'm not sure if this resolves the issue.
Here are the relevant config:
ASA Interface on the Switch:

i'm going mad on following problem. I'm trying to get 2 networks seeing each other while one of the network is a non VLAN network and the other one is a VLAN network.They should use the same interface so i added VLAN e0/0.122 to the interface e0/0.Send a ping from my asa to both gw-IP's made me happy at first. In second in figured out that i cannot reach any client in the other network. For testing purpose i created an permit acl to any/any for both networks, but the packets still get dropped by the default implicit rule. (deny any/anyMaybe i'm to stupid for this

I use the Cisco/Lyncsys E4200 router on my LAN and can re-connect to the storage on the local LAN by setting up Port Forwarding of port 21 and MS Windows FTP folder sharing. However, I can't seem to connect to a Terminal Services client by forwarding port 3389. Is there a way to connect to the local LAN after logging into the VPN connection. I can connect to regular HTTP/HTTPS sites and most other type of connectiins, just not my own local resources.

View 19 Replies View RelatedOur VMware guys want to use shared networking infrastructure to create a DMZ on a network.
[ASA (subif;VLAN 4)] <-trunk-> [DMZ Switch] <-trunk-> [LAN Core Switch] <-trunk-> [ESX vSwitch] <-VLAN 4-> [VM]
The DMZ Switch does not participate in VTP with the LAN but will have a VLAN ID created (same VLAN ID used from VM to ASA) No vlan interface will be created for the vlan
Is this a bad idea from a security or otherwise point of view? i.e. Best practices that should be followed here? Should I configure the link between the LAN Core Switch and DMZ switch as access ports so the port on each switch is forced to be on one specific vlan? I was going to use allowed vlans command to limit the vlans that can pass on it and possibly vtp pruning for all vlans.
what would be the best method to limit some users/workstations from accesing the internet on a vlan that has access to the internet?
I was thinking of just creating a whole new VLAN for those few workstations that doesnt access the internet or using ACLs on the ASA.
