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?
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.
3750 Stack (Voice gateway for phones configured on the 3750 and has a VPC nexus) + + + + + + (Nexus5596) ++++++++++ (Nexus5596) (Gateway for all other vlan like PC / servers / etc) + + + + + + 3750x access layer (VPC to Nexus) [CODE].....
The data sheet for the 2232PP says you can use a SFP-GE-T, but there is no mention of 100Mbps. I want to recommend to a customer that they use 2232PP for an upcoming core upgrade, but it may need to support some existing 100Mbps devices which are currently connected to 3750s.
We have Nexus 7009 switch and want to configure the span session
We are using F2 and M2 card both are in seperate differeent VDC.And out server is connected to M2 card on eth 4/6 and want to monitor the traffic from vlan 161Which is made on F2 card.
I have a RSPAN session configured between a Cisco 3750 and Cisco 2950 switches and I dont see the traffic I am expecting to see on the destination port. I only see broadcast traffic .. HRSP hellos etc. Below is what I have configured on both switches.
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.
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?
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.
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.
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
Ethernet VLAN Type Mode Status Reason Speed Po Ch Eth1/17 -- eth routed down L3 not ready 1000(D) -- Eth1/18 1 eth access down SFP not inserted 10G(D) -- Eth1/19 1 eth access down SFP not inserted 10G(D) -- Eth1/20 1 eth access down SFP not inserted 10G(D) -- Eth1/21 1 eth access down SFP not inserted 10G(D) --
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) ?
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 have a pair of 5596 running in a vPC with Nexus 2248 connected to each N5596. When I do the command "show fex" I get the following output on the 2nd 5596
Number Description State Model Serial ------------------------------------------------------------------------ 101 FEX101 AA Version Mismatch N2K-C2248TP-E-1GE SSI16390705 102 FEX102 AA Version Mismatch N2K-C2248TP-E-1GE SSI163704AD 122 FEX122 Online N2K-C2232PP-10GE SSI16370195
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?
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.
Does the nexus 7010 support virtual switching yet? All of the posts I have found from about a year ago say that it is going to be supported, but there were no dates listed. I heard the same thing from Cisco a while back, but haven't followed up with it.If it is supported finally are there any configuration guides available for it?
I have an issue on the Cat 3750 on the voice vlan; IP Phone not registering with PBX & Signaling Server. The ip phone hits dhcp and gets an ip address from a data scope. Data scope does have dhcp options for voice, same as voice scope so it should work but it doesnt.We removed the switchport access vlan 50 command, and left the switchport access voice vlan 51, and now the phone registers.Anything I can check on the switch to make sure voice vlan is working? Any debug voice vlan commands?The switch doesnt seem to distinguish voice and data traffic.I check dhcp and both scopes vlan 50 and vlan 51 have the same configuration. Defautl GW is different of course Catalyst 3750 is running 12.2(25)SEE2 [code]
Since Avaya phones do not run CDP, how does the phone know which DHCP pool to pull from to get its IP address if the PC is connected to the phone.
Let's say I have a interface config like this interface gigabitethernet1/0/1 cisco3750(config-if)#switchport mode trunk cisco3750(config-if)#switchport access vlan 126 [code]....
And two DHCP scopes configured on the switch. What keeps the phone from pulling from the wrong scope?
We recently purchased a pair of 2232TM Fabric eXtenders just to find out that our Nexus 7000 does not support it. Will there be support for the 2232TM FeX in Nexus 7000 any time soon?
if vPC is supported between a single 2232PP FEX and two 7000 switches running 6.0(1)? I have been researching this for an implementation I am doing for a client and was able to determine it was not supported with earlier versions of 5.0 when the FEX is connected via vPC as I described above, but I can't find anything related to version 6.0(1). I have done this for other clients with 5000 and 2000 switches, but I don't have too much experience with 7000 switches.
Iam having some issue trying to configure snmp-server context vrf XXX.From some reason even if i put my VRF name i cant see anything about this vrfthis is the command i add:
future support for IP Sla on the nexus 7000. The latest info that I've seen is that it will/could be supported in release 6.2, scheduled for mid 2012. Does this still accurate?
I am trying to install SFP-GE-T module on Nexus 5548UP Switch, but is giving the ‘SFP validation Failed’ error. The details of the switch is given below
Model : N5K-C5548UP-FA
The interface is configured with speed 1000 before inserting the module, still we are getting the same error. PFA logs for more details We have 8 Nos of SFP-GE-T modules , all are giving same error. We tried to insert the module on onboard as well as expansion module.
The same module is working fine on Cisco 3750X-24T-L Switch As per the Hardware installation guide , SFP-GE-T transciever is supported on N5K platform. Please extend your support in configuring SFP-GE-T module on N5K platform? We tried with SFP-GE-S module on the same switch , and the same is found working fine.
