I have two Nexus 5596UP that will be connected together via VPC-Peerlink. From there I want to connect both 5596UP's to a 6509-VSS via VPC.The Nexus 5596UP's will be essentially layer 2 switches, all routing will be done the 6509-VSS's.

I would like to make a design with 4 Nexus 5596UP. 2 of them equipped with Layer 3 Expansion Module so they can serve as core layer and the other 2 Nexus used as Layer 2 for aggregation server layer.The 2 Nexus in the core layer will run HSRP and will peer with ISP via BGP for Internet connection The 2 Nexus in the aggregation layer will be configured as layer 2 device and have FEX and switches connected to them.What I am ensure of is how the vpc and port-channel configuration should look like between the 4 nexus. What I was thinking is to run vpc between the 2 Nexus in the aggregation layer and between the 2 Nexus in the core layer. Than I was thinking of connecting each Nexus in the aggragtion layer to both Nexus in the core layer using port-channel and vice-versa.
View 3 Replies View RelatedI am trying to work up a config based on equipment that was ordered before I joined my current employer.
I will be deploying N2Ks at the top of each rack. Each N2K will be dual homed to two different N5K's. Being new to the Nexus, I understand that the N2K's have no brains and are dependent on the N5K's they connected to. Wasnt sure how to tell each 5K that the 2K that was dual connected to it needed to be able to move between N5K's based on failure/availability. I havent been able to find a sample config of what this will look like anywhere on the Nexus section of the Cisco site.
The next step after this will be to connect N5K_1 to blade on a 6509 and N5K_2 to a different blade on the same 6509. I will be installing two of the 10Gig blades in the 6509. Havent been able to find any sample configs on what this would look like either. We are upgrading the sup engines on the 6509 to the new 2T version.
When I read Nexus 5K install guide , I found the follow :The Cisco Nexus 5596UP switch has the following features: # •48 fixed 1- and 10-Gigabit Ethernet server connection ports on the back of the switch AND The 48 fixed ports support 8-, 4-, 2-, or 1-Gbps Fibre Channel transceivers and 1- or 10-Gigabit Ethernet transceivers. Does these is a conflict ?The 48 fixed port on this switch support only 1- and 10-Gigabit Ethernet or 8-, 4-, 2-, or 1-Gbps Fibre Channel and 1- or 10-Gigabit simultaneously ？

One of the two supervisors in an IOS 6509-E did not come back up after a power outage. The failed supervisor in slot 5 was replaced and it booted successfully. However, the supervisor in slot 5 only booted up to a "Cold" state. I did notice the Hw version of the replacement module in slot 5 is 4.9 while the Hw version in the supervisor module in slot 6 is 4.8. What command do I need to issue to bring the supervisor module in slot 5 from "Cold" to "Hot"? [code]

View 2 Replies View Relatedwe have a new IBM Bladechassie with two Cisco nexus 4001i switches.I have configured one external port on each nexus and connected them to a cisco 6509 with 1G cisco SFP-modules and MM fibre.Both the nexus and 6509 ports are configured as trunk ports, and set speed to 1000.I see light in the SFP-modules on both devices, and through the fibre. When I connect the devices, the link doesn't come up. No light on the ports, the nexus says "link not connected", and the 6509 says "notconnect". I have tried reconfiguring the ports in many ways, even as accessports, nothing seems to work. If I move the SFP and fibre from the 6509 over to a trunk port on a cisco c2960-24TC-L, the link comes up and everything is working fine. why this work on a 2960 and not my 6509 coreswitch?

We have two 5548 switches connected to a pair of 6509 running in VSS mode. I am trying to understand the benefit of having bridge assurance on the uplink ports.
If we have the command spanning-tree port type network enabled we cannot do a non disruptive upgrade. If there is bridge assurance on the uplink it warns you of this. Yet if I do not run bridge assurance on the uplinks I can do a upgrade without any disruption.
Why in god would I enable bridge assurance on this VPC link if I cannot do a non disruptive upgrade?
I am in the early planning stages for a 6509 to Nexus 7K migration. Based on my experience with the 7K's at a previous company where we ran into a lot of issues, I am trying to be very careful.
I am more at home with the 6500 chassis and know what I can do with them. I remember running into a limitation on the Nexus that involved their not supporting span sessions like the 6500's do. Is that still the case ?
If that isnt an option in the short term, I will need to look at a substantial investment in ethernet tap's to replace the lost span functionality because the security group's heavy use of span sessions.
I have the Cisco VSS consisting two chassis 6509.I have the system Active-Dual detection via Enhanced PAgP with one neighbor - standalone cisco 3750. All works good.I want to add one more neighbor - cisco stack 3750x with 3 members. Will this scheme work? And what is in danger, if the stack is split into two parts?
View 2 Replies View RelatedI am trying to interconnect a pair of Nexus 5548 at adjacent sites, using 2 2960-S switches at each site, the reason being that the Multimode Fiber between the sites will only support 100mb and I need this up while I finish having SMF laid.

Assume the interconnect between the 5548's needs to be 802.1q trunk
currently nexus 2000 and nexus 7000 does not support dual connection. you can not connect to 1 nexus 2000 to 2 nexus 7000 chasis. But for the nexus 5000, you can. what is the problem to to support this feature on Nexus 7000s? 5000s and 7000s run same software.

I wanted to know if any has the Nexus 7009 chassis installed into a 600 wide rack with the sides fitted and if they are experiencing heat issues?
My client will be replacing their aging 6509 chassis with 7009 devices, but the physicals dont tally with the install guidelines for the 7009 series chassis. The current install of the 6509s does not tally with the recommended install guidelines for those either, but they have not expereienced any heat issues...
The 7009 will be fitted with 2xSUP2E, 3x48portSFP-F2E cards and 2x10GSFP-M2 cards with 2x6K PSUs. I am genuinely concerned they may cook these devices, but space restrictions look like vetoing the upgrade to 800 wide racks. Likewise moving to 7010 chassis may prove tricky due to existing other installs within the racks limiting vertical space.
I have a two fiber connection from our Central Office(6513) to Remote office (6509). I have a requirement that on the remote office if one of the fiber goes down, the second fiber should work as a failover. I am planning to use SUP720-3B SFP to connect to the CO.
Can I connet one fiber to Sup720-3b G5/1 & another fiber connection to G5/2? or Can I connet one fiber to Sup720-3b G5/1 & another fiber connection to G6/2? I am running EIGRP between sites. Any sample config.

View 1 Replies View Relatedwe've had an issue with our network, we have 2 6509 connected with redundancy, which are connected with 2 x 4900 Switches, from which are connected to a ESX Chassis for visualization, the thing is that the ESX stopped working, and the 4900 switches, and the main core were suffering from overload, they hang on it very well, in order to stop the overload, one of the links to the ESX Chassis were disconnected from one of the 4900 switches. The CPU usage from the 4900 and the core(6509) went down below 40%, and then they started to migrate the virtual servers from the chassis to another 2 chassis that were added right after. They were actually working well, but suddenly the 6509 changed to the other supervisor after everything was OK. We were wondering what could have been the cause of this, maybe the virtual servers migrations, maybe the overload from the ESX ? We also had a few question, is there any need to reload the cores every few months as a planned task ? Because the cores have been up for more than 1 year. And also is there any kind of of tool to monitor the CPU status, or the status overall from the cores or the switches ?
View 3 Replies View RelatedThe have around 80 staff and I think the current infrastructure is overkill for the size of the company. The current kit is old and they have no GB ethernet ports. They currently have:-
Core Switch:
1x Cisco c6509with a 48 port fast ethernet module (WS-X6248-RJ-45)
and an 8 port fibre module (WS-X6408A-GBIC)
I'm looking to replace this with something with 72 ethernet ports and 8 fibre ports
Access Switches:

If client gateway = 192.168.64.9 then next-hop = 192.168.64.8 else use default-route 0.0.0.0
I know it's possible to do a route-map match ip-address ACL list. But is it possible to match on gateway?
Some info about hardware and config:
6509-E in VSS (IOS 12.2(17r)SX5) withVS-S720-10G supervisor.
All routes are static, IP for 192.168.64.9 is on SVI vlan.
I have two ISPs. Each is on it's own subnet connected to the 6509 MSFC/Switch. FW1 is on 100.1.100.0/30 and FW2 is on 200.1.200.0/30 subnet. My goal is route all traffice going to the Internet from subnet 10.133.3.0/24 to FW1 and all other subnets across the organization to FW2. I am not sure if I need to use ACL / Static route combo, or just a static routes or ACLS?
