View 2 RepliesI have a customer who has vlan's and SVIs residing on a core 6509. the 6509 is connected to an ASA 5515 then out to the internet/sp edge deviceIP routing is not turned on. there is a static route on the 6509 that routes all ip's to the inside interface of the asa 5515 that the 6509 core is connected to.there is a set of vlans that are apart of a 192.168.128.0/19 subnet and all those vlans can "speak" to each other.
View 8 Replies View RelatedSay I have a managed switch that supports VLANs. I have two computers and one server connected to the switch (I'll call them PC-1, PC-2, and SRV-1).Without routing, I want both PC-1 and PC-2 to talk to SRV-1 and vice versa, however I don't want PC-1 or PC-2 to talk to each other.I achieve this by making each port a trunk port. I make PC-1 a member of VLAN 2, PC-2 a member of VLAN 3, and SRV-1 a member of VLAN 4. The port that SRV-1 is on I make a tagged member of PC-1 and PC-2 (VLAN 2 and 3 respectively) and make the ports the PCs are on a member of the SRV-1 VLAN (VLAN 4).Everything tests OK (that is, the clients can't talk to each other, however the clients can individually talk to the server)
View 6 Replies View Relatedwe have an SG300 latest 1.3 firmware, we have it acting as our DHCP server, we have a 10.10.1.x range, 10.10.3.x range, and 192.168.24.x range, they are all on seperate VLANs and all can talk to each other which is what we want. However we have someone who wants to use the 192.168.1.x range to add IP cameras to our network using there own switch. I figured I'd just setup our server to do DHCP etc and it would communicate with the 10.10.1.x range of IP addresses no problem. It turns out the SG300s can't do DHCP for that range, so if he has all static address on the 192.168.1.x range how can i setup inter VLAN communication so we can talk to that range?

View 2 Replies View Relatedyou find attached my network architecture with 2 Nexus 7010 on core layer and 2 Nexus 5020 on distribution layer, each one with 1 N2148T fabric extender switch. PC-A1 and PC-A2 are connected to one N2148T, PC-B1 is connected to the other N2148T. Nexus-7000-1 is HSRP Active for all VLANs, Nexus-7000-2 is HSRP standby. PC-A1 and PC-A2 are connected to VLAN A, PC-B1 is connected to VLAN B. PC-A1 and PC-A2 have the same default gateway correspondent to IP HSRP on VLAN A. It happens that PC-A1 is able to ping PC-B1 while PC-A2 is unable to ping PC-B1. If I issue a traceroute from PC-A2 I see Nexus-7000-2’s physical IP address as the first hop even if Nexus-7000-2 is HSRP standby. After the first hop the traceroute is lost. If I shutdown Port-channel 20 on Nexus-5000-2, PC-A2 starts to ping PC-B1.I can’t understand what’s wrong in this architecture.

View 1 Replies View RelatedI'm looking for some input on configuring vPC on the Nexus 3048.I know that it's supported to use 1G interfaces for the vPC Peer-Link, but using 2x1G for the Peer-Link would make the Peer-Link a bottle-neck if the 10G ports are used in a vPC. What about using 2x10G ports for the Peer-Link and using the remaining 10G ports in one, or potentially two vPCs. Should that work or is it in any way not recommended? The reason I'm asking is that the 10G ports are called "Uplink" ports in the data sheets for the 3048.
We are planning to connect some servers to the 3048s using vPC with each server connected by 4x1G interface (2x1G for each switch), and then we want to connect a Netapp storage system with two controllers using 2x10G each (the controllers are active/passive, so you can think of it as two separate systems). We would connect controller A with vPC 1x10G to each switch, and controller B in the same way with vPC 1x10G to each switch.
Any way of policing traffic on the Nexus 3k platform? I can't find a reference to say policing/shaping is supported.

I'm trying to get a node in SVI1 on VRF1 to speak to another node in SVI2 on VRF2 to reach each other. After hours of failure, I went to outside resources. Everything I read on the internet says it's not possible on this platform and at least one TAC engineer seems to agree.
I just can't believe such a high-end data center switch is not capable of handling such a basic feature.
I just received a Nexus 5548 to configure as the core of the Datacenter LAN. Is it true that the VRFs created cannot talk to each other??? I can't seem to find any documentation on how to do this and at least one TAC engineer half-heartedly believes it's not possible, either.
Basically, I'm trying to get an SVI in VRF1 to be able to talk to an device on another SVI in VRF2.
I can't believe this high-end switch, that is so capable in every regard, cannot handle this feature.
Just messing around with packet tracer for a little practice. I tried to setup a router on a stick config with 3 switches trunked and PCs on different vlans. Anybody know of any issues that may arise with STP and inter-vlan routing? I set everything up correctly with trunking, addressing, encapsulations, vlans, but did not touch STP. Unable to ping from any PC to any where.
View 19 Replies View RelatedI have a working environment but wondering if there is just a better way to accomplish what I am trying to do (without a layer 3 or 4 switch). Basically I have a few sub interfaces on my Cisco ASA5510.
Now what I do need is some of the VLANs to communicate with specific devices on the different VLANs. So for example I need computer 1 from VLAN 5 to communicate with 192.168.10.5 from VLAN 10 on ports 80 and 443.
What I am currently doing is settings the security level to 100 on each interface (including the DMZ).

View 12 Replies View RelatedShort version is we cannot communicate between our subnets.We have a Cisco ASA 5505 we are using for our network router. We have a Netgear L3 switch behind that with 10 vlans. Each VLAN is on its own subnet. (10.0.10.x/24, 10.0.11.x/24, etc)We have PAT for each subnet to our outside interface. Each subnet NATs out properly currently.I have NAT exemption enabled for 2 of the subnets (eventually I will need all, but am just testing at the moment). I have tried multiple ways for the NAT exemption to allow all traffic from our inside VLANS. At this point in time I am trying to get "Engineering" to communicate with all hosts on "AuthUser". I can ping some hosts, but not as many as if I am directly on the interface. I can reach a port 80 service, but not 443. I cannot access anything via hostname or NetBIOS.What am I missing to allow higher security level interfaces to fully communicate with lower security level interfaces?
View 0 Replies View RelatedI have a connection on IP 192.168.1.21, Subnet 255.255.255.0 - this is on the default VLAN1 on the switch. I need to route this to IP 10.0.3.101, Subnet 255.255.252.0 - which is set up on VLAN2 on the switch. I have set the switch to Layer 3 via console.
how I setup this route? I am use the Browser based interface.
I have set up a 2811 with seperate VLANs for phones, and another for computers/printers. Fa0/0 is trunked to a 3560 switch, which has all end devices plugged in. I have enabled the IP Routing commands on both devices, and from advice turned off proxy-arp on the VLANs on the router (unsure if this is causing the issue). The setup is as follows
Computer VLAN = 192.168.20.0
Phone VLAN = 192.168.50.0
Both on the same subnet, along with a router loopback address in the same subnet, at 192.168.10.1.I am having an issue understanding why, but if I try to ping a phone from a PC it times out. Or if I try to type the phone's IP into an internet browser to get the phone's GUI on screen, it fails. This should not be happening as IP routing has been enabled on both, and everything is in the same subnet, correct? PC's can ping other PC's and network printing works fine. Phones register and operate fine, but the two VLAN's will not interoute.Furthermore if I try and ping the router's loopback from the switch, it fails. But the trunk is up and operational because DHCP and devices work within their own VLAN. If I try to ping end devices from the switch, it returns 100%. There seems to be an issue with the router looping the different networks together.
I've recently installed an SGE2010 switch, which I have set to 'Layer 3' mode.
I have created 2 VLANs using 192.168.10.x and 192.168.20.x (using .50 for the VLAN IP address in each case) - however, I need to be able to allow certain traffic between the VLANs.Alternatively, to get things started - I'm assuming I need to set up ACLs to allow access between VLANs - how would I configure the switch to allow all traffic from one VLAN to the other?
Ive been readin all over the internet (including this site) trying to figure out if the asa can handle intervlan routing. Im not sure what I am missing on my config to get this to work. Ive read that it can work and Ive read that it cant work. How to get this to work on my asa 5505.
Here is my setup
Cable Modem ---> ASA (eth0/0)

What I would like to do is be able to communicate between vlan3(LAN) and vlan4(Wireless LAN)
Whats strange is I can RDP between the two vlans but I cant ping or anything else.

OSPF is the routing protocol. Everything works fine.New requirement (exchange 2010 MAPI & DAG subnets)
192.168.5.0 <--> 192.168.30.0 & 10.10.30.0 : Communication should fail

Replicas --> Rest of the nw- not that of an issue.
Iam thinking of adding a Extended ACLs on Replica-Exchange (DC & DR) and servers Vlan interfaces to block bidirectional communication.

Similar to the same on DR as well. I wanted to see if ACL is the way to go or any other suggested methods with OSPF being the routing protocol.
We use Cisco Any connect with a Cisco ASA 5520 firewall. Today I changed the inside interface of the firewall's IP because i needed to do some inter vlan routing and needed to move the inside interface from the lan vlan to a routed port on our 3750.
Now people can vpn and authenticate to the MS radius inside but cannot access any network resources nor ping anything inside.
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?
configure my new SG300-28P. When I have started the switch, I have specified a new password and enabled telnet in order to setup the switch in Layer 3 mode.
After a restart, the switch took its IP address from a DHCP server. When I try to set a static IP address (192.168.2.1), I receive the following error message: Duplicated IP interface on the same subnet.
The IP address 192.168.2.1 is not used by any device within the network. For information, the message doesn't appear when the switch is in Layer 2 mode.
why I can't change the IP address of default vlan in Layer 3 mode ? All I can do is set the IP address to static or dynamic.
For test purpose, I have added 2 vlans. But I wasn't able to route traffic between vlan. how to configure the switch to route traffic between vlan?

In my home setup I have an PFsense firewall wich is doing all the routing right now, but right now my net speed is maxing out about 500mbit, i my think it's the pfsense hardware, but its an 1500Mhz C7 VIA with 2Gb ram, I just bought two new switchs, HP-1910-24g and a HP 5500-24G they can do some layer 3 routing, will my speed get a bumb up when the switch is doing some of the vlan routing.
