Apr 11, 2011With most of my Layer2/Layer3 switches, I'm accustom to giving them a SVI on my management VLAN, and calling it a day. I can't find in the Cisco Nexus guides how to do something similar; everything points to the mgmt0 physical interface, which seems like I need to uplink it to an access port on another switch. Can somebody point me in the right direction for how to do give the Nexus an IP that I can ssh/snmp into it across a trunk for management? I must just be missing the keyword.. NX-OS is still quite a different beast.I see in the manual it says: "SSH has the following prerequisites: You have configured IP on a Layer 3 interface, out-of-band on the mgmt 0 interface or inband on an Ethernet interface." Cisco Nexus 5000 Series Switch CLI Software Configuration Guide page 284, How do I configure an IP on a Layer 3 interface on a Nexus?

Sep 13, 2012I understand the vlans on the catalyst side of the house on 2900 to 6500 Catalyst switches.
This 7010 running nx-os 5.1(3) I did not setup, but have to manage it. Hasn't really been a proble till now.
My nexus 7010 has a Layer 2 only vlan 11. It is "Active" but the interface is "shutdown". Yet, it is passing traffic across the directly connected ports on the nexus 7010 and to other switches in my network. Vlan 11 is being set out via VTP to all my switches and things are running fine.
I need to create another L2 only Vlan. I can't seem to find any docs that indicate that a Layer2 vlan Interface on nx-os should be in "shutdown" mode as part of the setup. I do see in the docs where it has to be set "Active" as part of the process.
Is this the correct way to seutp a L2 only vlan on nex-os? Leave the interface in "shutdown" but make it "Active"?
Mystery Vlan 4 and 6
The mystery deepens. I have other L2 vlans ,Vlan4&6 that are NOT defined as "Interface Vlan4" in the nexus config, yet it is applied to GigE ports on the nexus and these Vlans 4/6is also being sent out VTP to all switches. Even weirder is that these vlans have names associated with the numbers. These are valid Vlans that were configured on the old 6509 before the Nexus was installed.
I have checked all switches, NONE are running in Server mode for VTP, all are in CLIENT. The nexus 7010 is the only device running in VTP Server mode.

Aug 14, 2012I've got a bunch of 3750-X switches all running IP Base and acting as a routed access layer. They run OSPF in a totally stubby area with the distribution layer (Nexus 7K) as the ABR. We also have a physically separate management network into which the fa0 management interface of the 3750-X is connected. The management network itself runs OSPF and has multiple subnets and external access.
On the 3750-X, I'd ideally like to be able to run some sort of separate OSPF process for the management network or at the very least have a static default route for management traffic pointing out the fa0 interface, but clearly not have it interfere with the main default route for data traffic coming from the N7K ABR. Normally I'd just create a management VRF, sling the fa0 interface into it and run a separate OSPF process in that VRF. The problem is you can't create VRFs in IP Base! Surely there must be a way to do this? Cisco don't really expect customers to upgrade to IP Services just to have a working OOB Management network, do they?!

Apr 20, 2012I have an old Nortel network with a bunch of servers attached. Connected to it is the new Cisco core, by way of a routed port. My task is to migrate servers over to the Cisco side of the network, with minimal downtime, and have full network connectivity, retain IP addresses/remain on the same subnet, and retire the Nortels. The Nortels are running VRRP, so I can fail the gateway over by becoming part of that group and later dropping the Nortels, but I can't seem to get a host on the Cisco side to participate in the original subnet. The routed port kills VLAN traffic, so I tried bridging the VLAN with the routed port, to no avail.

Basiclly, I want to be able to route ips from two different subnets on two different vlans. I've read through the docs and so far I have vlan1 setup and vlan 2 setup fine but I have no clue how to get the routing to cross vlans. The docs say the only way to have vlans talk to each other is by routing through the vlans ip interfaces but I have no clue how. There isn't a simple step 1,2,3 chapter that gets you to route between two vlans. What am I doing wrong? I put in some IP route entries but nothing seems to work.

Cisco VPN :: To Ensure That Traffic Is Not Just Being Routed Out Of Interface 3825
May 31, 2011I have my main branch router (3825) and two remote routers (2821's). They are connected through leased lines that do not touch the internet. For various security reasons I have to ensure that the traffic from the remote's are encrypted in a VPN tunnel even though it is still part of a private network.I have went ahead and created the tunnels and I can verify that they are up. I have applied the cryptomap to the correct interfaces, etc.So the question is - How do I ensure that traffic is not just being router out of the interface from the remote sites back to the branch router with or without using the VPN tunnel? I've taken down the tunnels and of course, the traffic is still being passed back and fourth.
View 1 Replies View RelatedCisco WAN :: 3745 - L2TPv3 And Routed Interface On Same Router
Oct 30, 2010I have a subnet (vlan 104) working great across a WAN. At site 1, Router A (3745) has the L2TPv3 tunnel configured while Router B (7204) has a routed interface on vlan 104.
The only thing router A is doing is the tunnel, so I'd like put the tunnel on Router B and eliminate Router A.
The trouble is, when I move the configs to Router B, the tunnel comes up, but the far side does not receive traffic over the tunnel.
Router B shows sending and receiving packets (per the 'sh l2tun session all' command). The far end router shows sending packets but receiving 0.
Is it a problem to have both the vlan 104's L2TPv3 xconnect interface and the vlan 104's routed inteface on the SAME router?

The core of the network contains two 6509E switches interconnected on a Layer 3 Port channel (no VSS). Access Layer switches (3750 Stacks) connect to the core switches over p2p routed links (Collapsed core part of the design). Distribution layer switches provide connectivity to the Data centre, Internet and Wireless Blocks.(three layer model.

Jul 12, 2012Our ISP has set up a Cisco 2431-16fxs IAD (dual WAN) in one of our locations. It is used to connect the devices (PCs and SIP phones) on our LAN to internet (via 1st WAN port) and ISP's MPLS-based voip network (via 2nd WAN port).
We have 2 LAN subnets - the first subnet (PCs) requires internet access only, so it goes out via the 1st WAN port. The 2nd subnet (SIP phones) is connected the MPLS network (via 2nd WAN port).
We would like to have the SIP phones (that connects to MPLS-based network 192.168.1.x) to be able to access the internet. Is it possible to configure the IAD so that the phones are routed based on destination network; i.e. anything to 192.168.1.x via 2nd WAN port, anything else to the internet via the 1st WAN port?

Apr 10, 2012I am using DHCP/TFTP to autoconfigure a 3945 router. The router properly obtains an IP address and finds the correct TFTP server. The issue lies in the download of the configuration file from the TFTP server. The router downloads the file, gives the "Ok" message, and prompts you to press Return to get started. When I view the running-config, several commands are missing from the Serial 0/0/0 section (HWIC-2T). If I modify the config file on the TFTP server to use Serial 0/0/1 instead and repeat the process, the configuration file loads without any issues and Serial 0/0/1 has all of the commands.
I also tried moving syntax around in my config file, but the end result is still the same. If I use Serial0/0/0 - I don't get all of the commands. If I use Serial 0/0/1, I do.
Cisco Wireless :: Inter Subnet Roaming With No Layer Device 3825
Mar 29, 2012The following picture is from a network in a hotel:
- Cisco 3825 is managed by AT&T. No access to this.
- There is no Layer 3 device in this network.
- Access Gateway at 100.1 operates at Layer 2. It receives tagged traffic in order to keep track of billings and user accounts so we can't add a Router in internal network. (Please verify)
- WLC's Management Interface lives in VLAN 100 at 100.2 with Default Gateway of 100.1
- Another WLC with Management Interface different VLAN than above, will be connected to the "Core Switch" to have Mobility.
- With Mobility Groups, IP connectivity must exist between the management interfaces of all controllers.
- Routing between VLANs need a Layer 3 device.
Any possible solutions to establish IP connectivity about the following:
- Changing Management Interface VLAN on one side and match it with the other side to eliminate Routing Requirements and having Inter-Controller Roaming instead of Inter-Subnet Roaming. (Reboot required?)
- Adding a NAT device between two WLCs and use Proxy ARP. (Haven't done this before, does this work?)
- Do you have better solution(s) in mind?

Jul 7, 2012How to configure traffic flow between computers inside VLANs and a routed port? Here is the setup details:
1. Switch 3750-X
2. VLAN 100 - ( SVI IP address 192.168.100.1 /24)
3. VLAN 200 - ( SVI IP address 192.168.200.1 /24)
4. routed port gi1/0/48 (IP address 192.168.150.1 /24). Note: this port is directly connected to a firewall ASA 5520 port IP 192.168.150.100 /24
Ip routing is enabled on the switch and inter vlan traffic is flowing ok. I can ping the routed port gi1/0/48 from any computer connected in the VLAN 100 or 200. For example computer with IP 192.168.100.25 can ping the routed port 192.168.150.1. Switch can ping firewall port 192.168.150.100 and the 'sh ip route' command shows the network 192.168.150.0 /24 as directly connected network.
any computer in the two VLANs CANNOT ping firewall ASA port 192.168.150.100 Is it because inter VLAN routing does not work with a routed port on L3 switch? I looked up fallback bridging, but it is meant for non IP traffic.The goal is I am trying to set the ASA port as an internet gateway for VLANs.
