Cisco Application :: Inband Management On Nx 7010 Without M1 Card
Nov 16, 2011
I would want to create an inband management (in case of we are a issue on OOB mgmt, i means to have a 2960 HS) on Nx7010 chassis without M1 card (only F1 cards - layer 2). I could create a interfce vlan but the status of the interface is down/down.
I have an other 2 x Nx7010 pair with M1 card ; for this pair, i can connect the interface ; the inband interfaces is up/up.I have also 2 x Nx5596 pair ; for these boxes, i can connect the interface ; the inband interfaces is up/up.Do you know a solution to get 1 interface vlan up/up on chassis 7010 without M1 card in order to have an inband connexion ?

we do not have an out-of-band management network and setting one up at this point is not being planned. We are mainly a swtiched environment and the only devices that are using L3 are the core switch for WAN purposes and the lab because it is mimicking the production environment. I have two Nexus switches that are sitting on the other side of a 3750 switch which is currently acting as a L3 device because this is a pre-production environment for a new project. We had an issue with management of the devices before but our workaround was to put them on the management vlan direcltly off of the core, allowing only management traffic to pass by means of mgmt0 on each device. The problem I'm having now is that I've now setup the mgmt0 interfaces on both for the keepalive link for vpc only (vpc traffic is going accross 2x10gb connections and the link to the 3750 is 1gb each trunked) and have lost my ability to use the mgmt0 connections for management. How to connect my management connection through either the 3750 or directly off the core switch (as that's what will happen once it's put into production)

We have a couple of Nexus 7010's split into Core and Distribution VDCs. MGMT0 interfaces on each of the Nexus VDC's (including the Admin VDC) are configured with different IP address, but on the same subnet i.e 10.10.10.1/24 for admin, 10.10.10.2/24 for Core and 10.10.10.3/24 for Distribution. The MGMT 0 physical port on each Nexus is connected to a physical gig port on a 3750 X switch, and the 3750X has uplinks back to the Nexus configured for vPC.
When i ssh to the VDC MGMT0 IPs from the 3750X, i can access each of these VDCs without any problems. But if i enable routing on each of these links(OSPF) and advertise it to the WAN, i cannot see these routes advertised and also cannot see any of these routes in the local routing table.Just wondering if i have to enable these links on a VLAN and then advertise it to the WAN..But if this the case, VLANs cannot be created on the Admin(default VDC).

I have LMS 4.1 and I'm trying to render a Nexus 7010 in Ciscoview. I have downloaded the latest package files. The Sup2 and Fab2 modules (N7K-SUP2 and N7K-C7010-FAB-2) show as "unsupported card".What packages and versions are required to recognize this card with LMS 4.1?

Am trying to replicate the managment interface functionality of a CSS on ACE 4710 but have problem with it being treated as a general routed interface.
Scenario
On ACE 4710 I have a front-end interface for client facing VIPS and a back-end interface facing a server farm, taking care of load balancing flows
Non load-balance system traffic for the back-end servers also flows through these two ACE interfaces, following a default route path (the back-ends use the ACE as default gateway) i.e. dns requests from the servers flow through the ACE egressing the front-end interface to hit a firewall and route to an internal dns server.
Issue
If I add a "management interface" to the ACE 4710 and give it an IP address for management access, the interface by default assumes 'routed' mode and as the ACE treats this as a general interface it will route traffic out of it. For example if the IP address of this management interface is on the same network as the internal dns server, it breaks that connectivity. This as the ACE will see the "management" interface as best route to directly connected network and send traffic to dns server over that, however dns server response traffic will follow its defult route path via firewall and ACE front-end interface to get reply to back-end server. The firewall will block this traffic as traffic is asymmetrically routed and firewall not seen the initial dns request packet.
Question
Is there a way of making an ACE interface a 'non routed' management only interface for out of band management use? That is ACE will not attempt to route general traffic through the interface
I realise I could achieve this with multiple contexts but want to have a single context for various reasons - i.e. to have a kind of like for like CSS replacement using ACE 4710

I am new to the ACE30. I a basic configuration from the CLI and I am trying to use the device manger. I am able to get to the web informational page rather then accessing the login page. I have rest the password for both the admin and www and still no go. my question is how to go into enabling the GUI access.

We've got pairs of ACE30s in our data centers set up with active/standby FT. Some time yesterday the active ACE in one data center started refusing management traffic - it accepts SSH connections but fails authentication (local password, no RADIUS/TACACS is configured); and ANM reports it as down (no XML connectivity),We haven't opened a TAC case yet - someone's on his way over to see whether we can get in through the serial port first - but I'm wondering whether there are any other diagnostics we can gather (will resetting the module form the Sup force a coredump?) before we do.

I have an HA ACE deployment and all seemed to be working well until I tried to access the ACE via the management VLAN in the one non-system context, no go.The ACE is in one-armed mode with an Admin/System context and one user context (named Messaging). Source NAT has been set up in the user context. All VLANs are in a port channel back to the core switches.I can access the ACE via the Management VLAN in the system context, all OK. I can access the load-balanced servers via the VIP in the user/Messaging context, all OK. I CANNOT acccess the managment VLAN other than ping it (resonds to ping, but telnet, ssh, https, etc. fails).The system/Admin context has a default route to the Management VLAN on the core. The User/Messaging context has a default route to the core switches on VLAN 5, which is the VLAN where the VIP resides.If I change the default route in the User/Messaging context to the Management interface on the core switches then I can access both contexts for management, but then the load-balancing falls over and I cannot access the serverfarm (via the VIP). Traces on the rservers show that NAT is being hit on the ACE and the requests are coming from the real IP of the clients. Put the default route back to the User/Messaging VLAN on the core and NAT is back to what it would be expected to be, and then remote/management access to the ACE is gone.

I am looking at management (backup of the configuration) of the ACE 4710 running A4.1, the management software is Cisco Cirrus. The question I have is around the management of the context's, I have a backup of the Admin but would like the user context's also, how this is completed.

We have a workng NAC 4.9.0 environment. When looking through the documentaiton areas I only see setup info for VPN concentrator and NAC in band. Are there setup examples with an ASA runnign newer code (8.6). The second piece is that I have some confusion as to the CAS setup. If it is in-band should it be done as a Real-IP gateway? Or can i get away with L2 in-band? We come off of the ASA inside interface to the trusted side of the CAS. The untrusted side of the CAS goes to the LAN. The CAM is 4 routed hops away.

we have e requirement for a Nexus 5000 switch to be accessed and managed inband, ie the Management interface can't be connected to the rest of our networks management VLAN because the switch is remote and only connected via fibre. We have enabled the interface VLAN feature and configured an interface VLAN but can't seem to PING the IP address configured on it ?

In our LAN network design, we have two Nexus 7010 switches on the core connected via vPC. Then LAN access switches are directly connected to the Core Nexus switches via regular port channels on the 3750's and vPC on Nexus. The core Nexus switches will be linked to an existing LAN network and the applications will be progressively migrated from the old to the new network.In this scenario, three VDCs are planned to be configured on the Nexus - One for the Interconnect (and WAN at a later stage), one for the LAN/local services and one for the building facilities/local services.

we have 2xNexus model 7010 (let's call them Nexus1 and Nexus2) connected via VPC to a couple of catalyst 6509 switch.Trunking has been enabled on the port-channel defined on both Nexus allowing some vlans.Below the config applied on both port-channel interfaces on both Nexus which are members of the same VPC number: [code]
supposing I'd need to remove some vlans from that trunk (e.g. vlan 100,200 and 300) using command "switchport trunk allowed vlan remove 100,200,300" and that I'll run that command on Nexus at a time (that means there'll be a condition for a short period of time where Nexus1 has removed vlan 100,200 and 300 from the trunk, while Nexus2 is still carrying those 3 vlans on its port-channel which is a VPC member) , could it cause any VPC inconsistency condition suspending VPC interfaces and therefore affecting the service for all remaining Vlans or only Vlan 100, 200 and 300 will be suspended when that condition will be detected?

We recently replaced our core switch from a non-cisco vendor with a Nexus 7010. With our old core switch, I had the ability to log changes to the ARP table. So if there was a dhcp conflict or a vMotion event, it would show up in the "show log" output. I've not found a way to do that with the Nexus switch - or at least no way to view the log. I have the command: logging level arp 6

Setting up Netflow from the 7010 platform to Solarwinds?I implemented the following code on both of my cores (VPC/HSRP Redundant Linked Pair) but had the following issues:
1. One of the cores I could see was sending Netflow records every few seconds whereas the other was not doing anything
2. Solarwinds was not seeing any of those records coming in and was showing last update from both devices as "Never"
Note that I have netflow already working as my Riverbed (fairly intelligently) already updates Netflow.Also i was all set to debug this myself but there doesn't seem to be debugging for Netflow that I can see?!?

I have to upgrade a Nexus 7010 with dual Sup engines from 4.2(4) to 5.2 and am hoping it could be an ISSU. We are fine with an outage window.To upgrade from 4.2(4) to 5.2(5) I'll have to do a multi hop upgrade from 4.2(4) - 4.2(6) - 5.2(5) and each hop would take 40-60 minutes.do I spend 40-60 minutes for each hop, or just do a disruptive upgrade straight from 4.2(4) to 5.2(5)? Like I said, we are fine with an outage window.

I have two Nexus 7010 in the data center. I'm unable to poll SNMP data from one of the NEXUS 7010s. The other Nexus 7010 is working fine. I have compared the SNMP configurations, and they are identical. When I do "show snmp" on the non-working switch, I have SNMP packets in "Unknown Context name", not sure why. I have done show vdc and it matches the working switch output. Here is output of show snmp from the non-working switch: 133 SNMP packets input 0 Bad SNMP versions 0 Unknown community name 0 Illegal operation for community name supplied 0 Encoding errors 0 Number of requested variables 0 Number of altered variables 0 Get-request PDUs 0 Get-next PDUs 0 Set-request PDUs 0 No such name PDU 0 Bad value PDU 0 Read Only PDU 0 General errors 0 Get Responses 133 Unknown Context name0 SNMP packets output 0 Trap PDU 0 Too big errors 0 No such name errors 0 Bad values errors 0 General errors 0 Get Requests 0 Get Next Requests 0 Set Requests 0 Get Responses 0 Silent drops.
