I am deploying a pair of Nexus 5596's with 3750 POE switches in the closets. I'm looking for a best practice as how to configure the Nexus 5596 to support proper QoS for EF at the core.
View 6 Repliesthe 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?
what is the equivalent command to configure on the Nexus 5596? OS version 5.1(3)N2(1) Catalyst 45k ip igmp snooping vlan 1036 mrouter interface Po20
View 1 Replies View RelatedI 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.

View 4 Replies View RelatedWe 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?

View 4 Replies View RelatedI 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.
View 2 Replies View Relatedi 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.
we have configured VpC between two Nexus 5596, for Vpc-Keep-alive-link we configured L3 interface with 1G (GLC-T) ,it shows the below status message "L3 not Ready" with interface LED glows in Yellow in color. is this a physical layer problem

I am looking for a router to route between VLANs on a Cisco Small Business 300 Series 10-port Gigabit Managed Switch.The router needs to support 802.1Q and also have Gigabit ports.I have been looking at the Cisco small business RV series of routers but most of these seem like Wireless routers and I don't know if these will act as proper routers.I already have a Cisco SRP547 and this does not seem to have proper 802.1Q support.
View 12 Replies View RelatedWe 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) ?
this is a Nexus 5596 L3 with the latest code:
It looks like the deny statement is not working as I can see all routes I am redistributing. I even did a deny on a specific route and I still see it in the routing table on another router in the autonomous system.The same below works fine on IOS platform. [code]

I'm running version 5.1(3)N1(1) on both of the 5K's. I have looked through all the configuration and I am not understanding why I am getting this error. I have tried to look it up on [URL], but not having a ton of luck.
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 ....so 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.
I currently have Nexus 5596 pair with VPC peer link Po1 between them. My goal is to connect our new Nexus 7Ks to the 5K's using Fabric Path. My question is during this inital setup with the 7K's. Can I use the same port channel number on the 7K's as I did the 5K's? Is the port channel locally significat?

We're looking into Nexus to replace these switches in the long run.
i want to remove the sync-profile on each of two synchronized Nexus 5596UP without loosing the config stored in Switch-Profile. That means without connectivity interruption and re-configuration of interfaces in "conf t mode", for example. Since NX-OS Release 5.2(1)N1(1) there is a new command
switch(config-sync)# no switch-profile abc profile-onlyprofile-only—Deletes the switch profile without the local configuration.

I had a lot of questions when I began planning a pair of Nexus 7000 switches as a replacement for our 6500. How to publish my design and config. This is a medium sized network. I would have loved to see somone's configs for a similar implementation.

The company I work have finally decided to enter the 21st century and invest in a new telephone system (Interactive Intelligence) to replace the legacy system which has served us well for the past 10 years. The project has only just started and involves upgrading sections of CAT3 cabling to CAT6, replacing Cisco 3550 switches in one area of the building with Cisco 4507 switches and upgrading our Core switches with Cisco Nexus 7010's. The area that concerns me most is enabling the network for qos as I have very little experience with it. At the moment Im trying to read as much documentation as I can on QOS to bring myself up to speed.
The access layer switches will consist of a mixture of Cisco 3750 & 4507 switches connected to Cisco Nexus 7010 switches which will form a collapsed aggregation & core layer.
Basically, how I should approach this daunting task of making sure the network will support VOIP.
i configure the uplinks as etherchannel, i configure two svi interface on core switch int vlan 51(192.168.51.1) and int vlan 50(192.168.50.0) for this two svi int i configured two dhcp pool , when any of the pc is requesting for dhcp add i am getting dhcp request failed/

Is there any challenge if we place NxOS in core and IOS in distribution and Access layer??? how we are able to match sh run config in existing 6500 switch to Nexus 7009 NXOS?
We have one core switch and we are planning to add a 6509. Both are none VSS.All the access switches are Catalyst 3560 series.
We plan to have all 3560s to have a link to each of the core. Without VSS, it is not possible to etherchannel to both core switches correct?What protocol should I configure to prevent in case one core fails? HSRP, VRRP, GLBP?
Do I need to run spanning tree protocol? if so which one?What is the best way to connect from each Catalyst 3560 for load balancing and redundancy? One to each core?
I configure 3750 stack switch as core and 2960 stack switches as access layer switches.I connected my laptop to one of my core stack in VLAN 10 and I am pinging to one of my server in VLAN 1. What will be the minimum latency at the time of inter VALN routing
