Cisco Switching/Routing :: 5596 - Extending 10Gb/s LAN Between Sites

Dec 14, 2011

For a simple 4x sites design for backup consolidation (3x sites connected to one central site), does the design in the attached JPEG make sense and is the configuration achievable using the specified parts?
Brief Explanation:
- Each site is to have servers with 2x 10Gb/s Ethernet (both teamed/bonded/etc) and one NIC on each of the 2x switches in the site (if possible). Each site will also have 2x Cisco Nexus 5596UP Switch (though the P version may be used instead of the UP).
- Two of the sites are within 10KM of the central site
- The last site is about 35KM from the central site
- It is required to have a minimum bandwidth of 10Gb/s between any site and the central site
- I have specified 10Gb/s LW SFP+ and 10Gb/s LW SFP+ (for the 2x 10KM and 1x 35KM sites)
- are there any special licenses needed?
- as asked before, can such a "simple" design work as-is?
- what sort of single-mode fiber would fit the bill (especially for the 40KM link) - 9nm?

Cisco Switching/Routing :: Nexus 5596 UP L3 OSPF

Jan 3, 2013

I have 2 Nexus 5596UPs with a layer 3 cards that are exhibiting some very peculiar behavior.  The systems are running 5.1(3)N1(1).I have configured 2 VRF contexts each running their own OSPF process.  There is a static gateway of last resort configured on each VRF, which is to an upstream pair of 5585X's in Active/Active.  Each OSPF process has the "default-information originate always" command configured, however, backbone neighbors are not recieving a gateway of last resort from the 5596UPs.  The applicable configurations are show below.  All other routing information is passing correctly between devices in the network.  This network is not production, it is a proof of concept for a larger implementation.

Cisco Switching/Routing :: Nexus 5596 - VPC Keep Alive Over Non-VPC Trunk

Mar 19, 2012

We have setup a pair of Nexus 5596 L3 switches with 2 x 10Gbps LACP links between them to act as the vpc peer link. We also have another 2 x 10Gbps LACP links between the 5596 switches to carry non VPC VLANs, this is required to provide EIGRP routing between the switches and an upstream router.I have read that it is possible to setup the vpc keep-alive link over an SVI instead of the management interfaces. Is it ok to run the keep-alive SVI over the second LACP non VPC VLAN trunk or is it recommened to keep this seperate?

Cisco Switching/Routing :: Nexus 5596 / 2248 TP - Compatibility With SFP-10G-SR

Jan 31, 2012

I am looking to see if Nexus 5596UP & Nexus 2248TP GE compatible with SFP-10G-SR? The reason is because a consultant was hired on to "design" the network layout and has decided to purchase Cisco SFP+ Copper Twinax Cables which have a 10M limit. A small handful of the Data Center racks are 10-15M away... just out of reach of the Twinax. I would prefer NOT to move the LAN row so that it is more centered in the room. Can I use the SFP-10G-SR to connect the 2 switches (5596 & 2248) together? This SFP has a 26M reach on standard 10gig fiber, the small cost increase per connection is of no concern.

Cisco Switching/Routing :: 5596 Nexus In-band Management With SVI

Apr 16, 2013

i have: two nexus 5596 connected each other the mgmt0 is NOT in use SVI for keepalives with IP address and /30 netmask vpc-keepalives running over fiber in e1/1. this works well uplinks to datacenter distribution switch (Cat 6500 VSS) over fiber on port-channel 1 (e1/2 and e1/10), also carrying the management VLAN (vlan 14). SVI with an IP address for management purposes
I can't get this to work. i can ping my whole network from the nexus, but not the nexus from my network. also pinging inside the mgmt vlan is not possible.

Cisco Switching/Routing :: ERSPAN On Nexus 5596 HSRP Pair

Jul 6, 2012

We have HSRP between NexusA and NexusB with access layer switches connecting to the core using VPC, We are trying to setup a VAM  server Voice recording for Siemens phones. We need to span all voice vlan and point it to the VAM server the VAM server connects to a 3750 Stack considering the amount of traffic multiple span session can generate I plan to move the server to the Nexus directly and run a Local Span Session.

1- As we have two Nexus running HSRP and VAM server only connects physically to one NexusA (I can run local span on that nexusA)  the Second NexusB is not directly connected to the VAM server I plan to run ERSPAN so if this is the best design and which path will the span traffic take from Nexus B to NexusA will it go through the access layer switches depending on the vlans allowed on the uplinks or will it go through the 20 Gig uplink between the two Nexus allowing all vlans (VPN peer links) ? WE have approximately 10 voice vlans, Do we an example config for ERSPAN session where the source are vlans (As I am for fimilliar with RSPAN) ?

Cisco Switching/Routing :: Nexus 5596 Giving Error In Connection

Aug 28, 2012

I have 2 datacenters running same equipement (two Nexu 5596 with FEX).I just took a look at the log just to see if everything is ok and I saw that I have the same error message (a lot of times) at both location :
%SYSMGR-FEX100-5-HEARTBEAT_LOSS: Service "satctrl" heartbeat loss 2 ,max 7,I though it was a problem with my peerklink-keepalive connection but I see the word FEX i'm not sure...
Note that at both locations, my Nexus are connected back to back through the management port using transceivers. So it's a copper cable from the first nexus,  going into a transceiver, going to another transceiver in fiber and then back to copper to the other nexus.

Cisco Switching/Routing :: 5596 VLAN Traffic Span Across Vpc Peer-link

Apr 22, 2013

I have pair of 5596 switches in vPC. One host say "HOST A" is connected to the primary vPC peer and other "HOST B" on secondary vPC peer.Both are in same VLAN 10. Both hosts are vpc orphan ports as their NIC is configured in active/standby mode.I have configured span session on both vPC peers with span source as VLAN 10 in rx mode.Span destination is connected to secondary vPC peer. The issue here is that I am not able to capture the traffic originating from HOST A destined to HOST B which is traversing vPC peer-link.Same issue occurs for the traffic in reverse way and span destination on primary vPC peer. In a nutshell, any traffic which crosses vPC peer-link is not getting captured.
What could be the issue and is there any solution for it. Below mentioned is the span config and relevant interfaces. [code]

Cisco Switching/Routing :: 4500 Can Connect 10Gb SFP+ To Standard 1Gb SFP

Nov 15, 2011

I'm looking at provisioning a Catalyst 4500 with a WS-X4712-SFP+E module to allow for future 10Gb connectivity via 10Gb SFP+ interfaces.  These cards are backwards compatible with standard 1Gb SFP interfaces but I'm wondering about the other way around; ie. can you populate these blades with 10Gb SFP+ interfaces when they connect to Catalysts with only 1Gb SFP interfaces at the other end? 
The data sheets don't really explain this.  It seems pointless getting 10Gb SFP+ interfaces for the 4500 when it's only 1Gb at the access layer end, but these access switches will be replaced in the near future (~12 months) and if the 10Gb SFP+ interfaces support connections at 1Gb speeds upfront, it would mean I could retain these interfaces when the access switches upgrade to 10Gb connectivity capabilities down the track. Does the 10Gb SFP+ interfaces are compatible with 1Gb SFP's or only other 10Gb SFP+ interfaces?

Cisco Switching/Routing :: 6509-E VSS 10gb Port Count?

Created two 6509s as VSS with just one 10gb connection?I know it is recommended to use both the 10gb connections on the sup-720 from below configuration guide
Information about VSL Topology  
A VSS contains two chassis that communicate using the VSL, which is a  special port group. Configure both of the 10-Gigabit Ethernet ports on  the supervisor engines as VSL ports.
But will the VSS come up if I use just the one?

We are having troubles getting a 10Gig interface to come up with a carrier... it shows down down.We are using X2-10GB-LR on a 6500 and SM fiber, distance to carrier hand off is about 90 feet.
According to: [URL]
The receiver power on a X2-10GB-LRis
Our carrier is sending at +5db. Currently the interface is down.
My question is; would the interface even come up if it is receiving a powerful signal?
Here is DOM output for our interface.

Cisco Switching/Routing :: Phone Connects To 3750-A / Nexus 5596 Does Not Support RSPAN

Feb 20, 2013

the phone connects to the 3750-A access layer switch (VTP mode client) which connects to the nexus 5596  (The nexus is the layer 3 device and set to vtp mode server) and finally we have a Voice recorder that connects to another access layer 3750-B switch.(VTP mode client)

 For voice recording I need to setup RSPAN and the nexus5596 does not support  RSPAN will the following have any impact on the nexus
IF I move the 3750-B to VTP server mode and run the command remote span on the VLan I need to Rspan its going to update the VTP data base in short it will update the vlan.dat file for all the switch in that VTP domain.
AS the vtp update reaches the nexus saying there is a change (keeping in mind the nexus does not support rspan not sure hows its going to handle that request and how its going to update its vlan.dat file)
Is it going to incremment the VTP revision number? can it crash the vlan.dat file  on the nexus ? or do nothing and ignore the update and stop the update from proceeding to the 3750 A switch?

Cisco Switching/Routing :: Nexus 5548 10GB-LR Interfaces Not Coming Up

Jun 21, 2012

We are trying to connect 2 nexus 5558UP (5.1.(3)N1(1)) with 10G-SFP+-LR interfaces. The interfaces are not genuine cisco's (smartoptics) but as far as we can tell, they are accepted by the hardware. If we take a look at the optical levels, we can see that the switches can see eachother (double-checked by bringing down one interface to see if optical levels really disappears) on optical level, well within limits. I found a notice about changing debounce timers but this doesn't work, setting it to 0 or 1000 doesn't make a difference. Copies of the different show int commands can be found at the end of this text.
