Cisco Wireless :: 5508 - WLC 7.2 - Custom WebAuth Using Waep Template With HTTP Only

Apr 12, 2012

We are trying to get the waep template (default no changes) from the Cisco WebAuth bundle to work on a 5508 controller.
We've setup the controller to use the custom login.tar that comes with the waep template folder in the bundle. We setup the WLAN to work off the global template and we used the config network web-auth secureweb disable command to allow only http rather than https (which is supposed to work in 7.2 code)
When we test with the custom bundle, we get no answer from the controller, just a url of [URL]
If we turn custom off, and use internal everything works...
Just to be clear.. we aren't looking for authentication (user and pass) we are trying to do the enter your email and click accept to the aup method.

Cisco WAN :: 3825 - HTTP / HTTPS Protocol Errors With IOS 12.4 (16 - 25f)

Nov 7, 2011

Any issues with IOS 12.4(16) through 12.4(25f) with HTTP/HTTPS protocols running on a 3825 router? I have a remote site that accesses a corporate application over an MPLS, sometimes it works fine, other times it will hang for hours. No errors on circuits, interfaces, ethernet interfaces, etc. Response times are averaging 50ms even when the application freezes. The only thing I can think of is that it could be an issue with the IOS version.

Cisco Switching/Routing :: Connecting Nexus 7010 VDC With VPC

Jan 29, 2013

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.

Cisco Switching/Routing :: Logging In Nexus 7010 6.x?

Sep 19, 2012

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

Cisco Switching/Routing :: Nexus 7010 Dual Sup ISSU

Aug 7, 2012

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 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.

Cisco :: Unable To Poll SNMP Data From Nexus 7010

Apr 18, 2012

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.

Cisco WAN :: IP SLA And Object Tracking For Default Route On Nexus 7010

Mar 18, 2013

We have a Nexus 7010 running version 6.1(2). 
I'd like to use IP SLAs and object tracking to define static routes for specific source/destination traffic across some WAN links we have.  I've done this in IOS and it's worked fantastically, but I've not found where/how to do this on the Nexus 7010 platform (or any Nexus platform) as of yet.  I could have sworn that this was going to be introduced in the 6.x code?  Below is an example of how we do this in the IOS world:
track 11 ip sla 1 reachability
delay down 15 up 15
ip sla 1

Esentially this gives us the option of using a "failover" default route.  I've attached a basic diagram to explain what we are trying to do with IP SLAs and object checking.  The tracking should be configured against an SLA that uses icmp and the static routes should be configured against the tracking.

Cisco Switching/Routing :: Surges In Nexus 7010 Latency

Dec 2, 2011

I just deployed a nexus 7010 switch at a server farm. after deployment, it was notices that there are surges in latency across the network. The default gateway was then moved to the nexus, with this pinging from an host on the same subnet there is intermitent burst is latency

Ping of about 80ms and sometimes even times out.
To me, this is strange.

Cisco Switching/Routing :: Creating VPC On Single Nexus 7010?

Jan 6, 2013

I'm looking to see if it is possible to run a vPC between to vDC's on a single 7010?  We have a Production setup that runs dual 7010's with vPC's between the chassis but in our lab we only have a single 7010 with a 32 port 10gig module.  I was thinking that maybe we could create 4 vDC's on the 7010 and run a vPC between the vDC's.

Cisco Switching/Routing :: Management Interface On Nexus 7010?

Apr 28, 2013

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 for admin, for Core and 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).

Cisco Switching/Routing :: Nexus 7010 And Connection With EIGRP

Mar 20, 2012

We have, for nearly 4 years, used EIGRP on our 6513 to  make use of two unequal links to our branch offices.  This worked because we could use the variance command and cause EIGRP to insert two routes into the table, one from each carrier.  Thus it was we could balance the load to each one with a ratio similar to the ratio of the bandwidth of Link A to Link B.
We just purchased 2 Nexus 7010's to replace our single 6513 core.After much consternation we have found from our Ciscio SE that the Nexus 6.0.2 software rendition of EIGRP does not support variance. 
Why would Cisco take their own propriatary protocol and then gut it by removing features?  I'm quite ready to send these Nexus boxes back in favor of a newer 6500 series.  MEC doesn't work like it is supposed to and the show-tech runs for over 24 hours without ever finishing (and this we can repeat on both boxes, multiple times).
We've opened a tac case but I just wondered for any work around for the 'variance' command?

Cisco :: Nexus 7010 - Opinion Of Model Support Network?

Apr 23, 2013

As a Senior Network Engineer I have entered into a bit of a debate with our Architect about the use of the mgmt0 interfaces on the nexus 7010 switch (dual-sups, M2 and F2 linecards).I would like to know opinion of the Cisco support network.

I believe the mgmt0 interface should left alone for control plane traffic only and Out Of Band management access (ie ssh).  At the moment I have made a subnet for all VDCs with the mgmt0 (vrf management) sitting in a common subnet.  The physical mgmt0 interfaces from both SUPs are connected a management hand off switch.  The mgmt0s also serves as our control plane for VPCs. The VPC peer-link however is using main interfaces of the line-cards.
The opinions;

- The Architect thinks we should use all the mgmt0 interfaces for snmp, ntp, tacacs netflow-analysis and switch management.

- However, I think I should use a traditional Loopback to perform these functions within the linecards.  The mgmt0 should only be used if traditional restricted switch access has failed.

My Basis;

the Loopback never goes down, uses multiple paths (the OOB hand off switch could fail closing switch management access completely).  The mgmt0 should be used as a last resort of management access to CMP.
