Cisco Switching/Routing :: ASA5510 / Two Routers On Same Physical Lan With Identical VLANs On Each?

Mar 17, 2013

I have 2 ASA5510's acting as routers/firewalls, setup on a LAN, each one pointing to a different gateway (different ISPs), and the exact same VLANs set up as sub-interfaces on each of these. Both act as DHCP relays to a Windows Server 2008 DHCP server. All the Trunking has been setup and works. When I Untag a switch port, and point it to whichever gateway?

Cisco Switches :: Passing Voice And Data Vlans On SG200-08P?

Apr 12, 2012

I'm struggling with a configuration issue on the Cisco SG200-08P. We are using the Cisco SG200-08P on a mobile cart that will go from class room to class room that will have computer and cisco Voip phone plugged into it. The issue is that each of our closets are in differnt VLANS ( 1 voice and 1 data....lets say data vlan 20 and voice vlan 2025 for conversation) and that we route to each closet.It would be great if I could just create a generic data and voice vlan to dynamically pick up what the upstream switch has however, it seems that I've been unsuccessful in doing so. I can pass the data Vlan no probablem. The upstream switch port is set to access port and a switch port access voice vlan (these are 3750x switches) If the above is not possible I guess I will take what I can get. Should I just create data vlan 20 and voice vlan2025 on the Cisco SG200-08P and make a trunk port on the Cisco SG200-08P and a trunk on the 3750x? Is there an option on the Cisco SG200-08P to tag voice traffic?I'm also concerned with VTP and I did not see an area in the Cisco SG200-08P to set that as a client and transparent mode.

Linksys Wireless Router :: WRT120N LAN Port 1 Flashing But Not Connected To Physical Port

Jun 24, 2012

I've been using a WRT120N on a local area connection.The WRT120N acts as a gateway and also to connect to the PPOE connection, via a bridged adsl modem.I've noticed that the LAN port 1 was flashing although the network cable was disconnected from the physical port. I've restarted a few times but to no avail as well. Ever since that, I've noticed that connection through cable are unstable and hard.Now, I'm not able to reset or upgrade the router's firmware.Is there any other way to be done so that I can get this router working as normal again.

Cisco Switching/Routing :: SG300 Network Setup For Voice And Other VLANs?

Mar 18, 2013

I have spent several days tearing my hair out trying to properly configure our small business switch (SG300-10p) for voice. The phones are a relatively new addition and will replace old POTS phones.Our network consists of a 1941 ISR router, the SG300-10P switch, a mac server (handing DHCP, DNS, AFP), 4 client desktops and 4 SGA525G2 IP phones. The router, server, desktops and phones all have their own connection to the switch and the second data ports on the back of the IP phones are not used. We do not have any unified comms devices for voice. Our VOIP solution is hosted by a local SIP provider, and each phone independently registers with the provider's SIP proxy over the internet.

Left almost to it’s own devices (or presumably flat, default settings on VLAN 1), this whole setup works just great. We can TFTP files, make and receive calls, and do all the usual XML stuff. Calls are crystal clear. Even the localisation and directory works. However, I’ve been told several times that to ensure good quality on VOIP calls during periods of busy traffic, I should set up some form of QoS. A Voice VLAN on the switch, I was told, is the best way to do this as it automagically gives priority to the whole voice VLAN over the normal data VLAN.

I have followed instructions in numerous manuals, articles and guides, and have managed to create the Voice VLAN, both manually and automatically (I can watch Smartport detect the phones and see the Auto Voice VLAN add the ports to the VLAN as I connect them). The trouble is, as soon as this happens, the phones lose connectivity with the rest of the network, including the DNS server and the router, and therefore the internet, causing them to lose registration with the SIP service.

I tried adding the server and router ports to the Voice VLAN and tweaking every possible combination of tagged, untagged, excluded, trunk, access, general and PVID settings I can think of (by the way, I have no idea what any of those mean). The switch is in Layer 2 mode, but adding the port connected to the router to all the VLANs does not result in internet connectivity to the phones. I have told the phones to tag frames with the VLAN ID and told them not to. I have tried upgrading firmware and I have rebooted the switch so many times I'm tired of those wretched little flashing lights.
Nothing seems to work. And so I am stuck with everything on VLAN 1. My most recent thought is that the 1941 needs to know about the Voice VLAN (I checked CDP and it knows about the switch), but I’m reluctant to start messing with the router config when this is our production network, at least without knowing what I'm doing. I don’t even know if QoS applies when a Voice VLAN is not set up and we're on VLAN 1, some articles say yes, others say no. And when it is set up right, how does that priority transfer to the router? I’ve looked in the router manual and config options and found something called 802.1Q, but I have no idea what it is, how it works or even if it applies to our situation. Can I forgo VLANs altogether and use QoS some other way, perhaps?I have googled enough to cobble together our setup in IOS up until now. Ideally, I would still like to be able to ssh or https into each device (as I do now) for management, and I’ve read about setting up a another VLAN for config, monitoring etc, but I guess that would mean routing between VLANs in Layer 3.

Cisco Switching/Routing :: Data And Voice VLANs Communication 1921

Dec 11, 2012

I wanted to know about EHWIC 8-Port configuration?  We create  Data and Voice VLANs and assign 8 ports to the VLANs. So how do VLANS communicate with each other? We cannot make Gi0/1 as sub interfaces and assign the same subnet IP’s as of VLAN IP’s , it wont accept. On 1921 router Assume Gi0/0 we connect to MPLS WAN. What happens to Gi0/1 where do we connect this?

Cisco Switching/Routing :: Configure Port-Channel Or Physical Interface On 3750

Jan 12, 2012

how to configure this. I did it in the past but kind of forgot how I did it.I have a stacked 3750 (two physical switches) connecting to a 2960.
I am creating trunk ports with limited access to VLAN 300, 600, and 700.
There is two interfaces connected from the 3750's(one on each physical stack member) to the 2960.I have the physical interfaces configured exactly the same.
3750 Config:
interface Port-channel2
 interface FastEthernet1/0/46
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1, 300,600,700
switchport mode trunk
speed 100


Should I keep the configuration on the physical ports and not configure the Port-Channel Interfaces? Do I need to configure port-channel load balancing? Is the channel-group mode sufficient? Goal is to basically create 2 links to the 2960 to double the bandwidth and provide redundancy.

Cisco Application Networking :: ACE4710 - Can't Assign IP Address To Physical Ethernet Port

Jan 4, 2013

My customer wants each ACE4710 (of a highly available cluster) to have its own, dedicated port for management purposes.
According to documentation, IP addressing can be applied to VLAN interfaces, so in order to satisfy the requirement, I should make one port belong to an "access VLAN X", and then apply IP addressing to the corresponding "interface VLAN X". This should satisfy my customer´s requirement in an indirect way.
But... ¿ Can´t I just configure IP address on one of the 4 ethernet ports in order to save the work of building the aforementioned VLAN? I am asking this since I do not have access to a real box in order to verify.

Cisco Switching/Routing :: 3560 Port Security And Voice Vlan On Newer IOS

May 20, 2010

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.

Cisco Switching/Routing :: 3560 - What Happens When Voice Vlan Command Is Added To Trunk Port

Oct 11, 2010

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.

Cisco :: Switchport Voice Vlan Command Not Putting Port In VLAN?

Feb 2, 2011

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?

Cisco :: 3560 - LMS 4.0 - Configure Port Assignment Only For Native Vlans Possible

Jul 19, 2011

is it possible with LMS 4.0 and VLAN Port Assignment also to configure auxiliary vlans?
1. I selected Configuration > Workflows > VLAN > Configure Port  Assignment.
2. Selected my device (a test switch WS-C3560-8PC-S)
3. Clicked List Ports
All ports were listed, port Fa0/1 has only a native vlan, the ports Fa0/2 - 8 have native and voice vlans (auxiliary) configured manually.
So when I want to configure the voice vlan for Fa0/1 the voice vlan is set as the native one.
Is it only possible to configure the native vlans with the VLAN Port Assignment of LMS 4.0 ?

Cisco WAN :: Cat 3560-E / 2960-G - Configuring Two VLANs On Same Switch Port

Mar 29, 2012

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.


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.

Cisco Switching/Routing :: 6500s / VLANs - Where To Put Promiscuous Port

Apr 25, 2013

We have a typicaly environment, access, distribution, core, all switches are 6500s.I have a lab environment where machines should not talk to each other, so I think private vlans would be good for this. The problem is that the access connects to the distribution with a 802.1q trunk, while the distribution connects to the core with an 802.1q trunk. See the attached image for reference.
In this case, I would configure the primary vlan (888) on the two access switches, as well as the isolated (886) and the community (887), and set the associations.
vlan 886
name Isolated_PVLAN
private-vlan isloated
vlan 887
name Community_PVLAN
private-vlan community
vlan 888
private-vlan primary
private-vlan association 886,887
The host ports would be set as such.
interface g3/40
switchport mode private-vlan host
switchport private-vlan host-association 888 886
My question is where to I put the promiscuous port? Is it on the uplink between the access and distribution? And If I configure it as I have below, what about the other VLANs that are needed at the access switch? Do they still pass through the trunk as normal, even with the private-vlan configuration? Or would every other VLAN need to be configured as a secondary private-vlan on the promiscuous port?
interface g5/1
switchport mode private-vlan promiscuous
switchport private-vlan mapping 888 886,887
Also, would VLAN access-lists be a better method for controlling this traffic?
