I have a small doubt with Nexus 7k,5K,2k & 1K.We want to backup the running config to my desktop through tftp.When i tried to backup from Nexus switches showing like below Nexus 7K. [code]
It's showing two choices which one I have to follow "copy running-config startup-config" or "copy running-config startup-config Vdc-all". [code]
It's showing two choices which one I have to follow "copy running-config startup-config" or "copy running-config startup-config fabric"
It's showing three choices which one I have to follow "copy running-config startup-config" or "copy running-config startup-config fabric" or "copy running-config startup-config vdc-all". [code]
I need to backup my ASA 5505 configuration and restore it to default, then I'll configure manually the new config, but if something doesn't work I want to restore the backup made before.
I tried the "copy run tftp" command, and it always answers the same: Result of the command: "copy run tftp" [code] I read everywhere its supossed to prompt asking me tftp server address and file name.
we are planing to run HSRP on our Nexus 5ks (with L3 card) and we use VPC to connect the downstream UCS - Fabric Interconnects to the 5ks. I was wondering if the peer-gateway command is required under the vpc domain config? When you use HSRP with VPC, both the active and standby HSRP peers can forward layer3 traffic, isn`t that the same that peer-gateway would achieve?
I'm busy on configuring the backup of the configuration from Nexus switches 5K and 7K.I have installed COPSSH on my windows server and try to confiugre the sftp credentials. [code] I have tested from the CLI from the switch and i have the issue but if i use the default vrf 'default' it works fine.How can i change the command sent by DCNM to the Nexus in order to specify vrf default and not vrf management ?
I have two 4506 switches in my organization. Recently the office was relocated and when both the switches were booted they ignored the startup config.The config-reg was set to 0x2101. No boot system command was configured.So I changed the config-reg of SW1 to 0x2102 and gave boot system command as stated below.When reloaded the switch booted to ROMMON and I had to manually boot the IOS.I want them to boot normally with IOS.Config of SW2 is not changed since relocation. I am specifying both configs bor your consideration. [code]
I have a scenario where 15 c500 switches and 5 2960 8 port switch connected to 4507R core switch. There are 10 dhcp pools created on the 4507.
Eg: ip dhcp pool XXXX network xxxx.xxxxxxx default-router x.x.x.x
Now the default router is directed to vlans created on the switch i.e vlan 101, 102, 103 and so on. Now the remaining switches connected are configured to be in the same vlan. So the systems connected to the edge switches will get the DHCP ip automatically, Now my problem is after sometime (may be 2 or 3 hrs) all the edge switches are losing configuration automatically even though it's not restarted, even after saving the config on to nvram, everytime I connect the console and check all the saved config is lost?
I have two 5548's in sync mode: I have an existing ACL and I want to add a new line to it, but after I do and try to commit it states the verify failed. [code]
I have to add access list to both switches not in config sync mode.
If i connected the latop to brand new out of the box ASA 5505 through consloe cable and i have a config file on this laptop from other ASA5505, is there anyway i can upload that config file into startup-config of this new ASA5505 through console cable, without using TFTP or FTP?
I've been asked whether we can use HP-branded 10G SFP+s (P/N 455885-001) in Nexus 2Ks to provide 10G connections to HP C-Class enclosures. We've used HP-branded twinax, and Cisco-branded SFP+s and twinax, but we have a raft of HP 10G SFP+s sat in a store room gathering dust and now we want to save some money by not having to buy the Cisco parts to match.
Configuring OSPFv2 on a Nexus 5K switches, after configuring area 0 or area 10 it shows as 0.0.0.0 or 0.0.0.10 instead, I'm planning to uplink a couple of ASAs with OSPF enabled, just wondering if the area format showing will be a problem, is this how is supposed to look in the Nexus 5K? and will the 5K be able to form adjacensies with other non-Nexus devices that have area 0 and 10?
I have 2 sites located approximately 30 kilometers apart. I will call them site 1 and site 2.The sites are connected by a Layer 2 1GB fibre connection.I would like to add 2 X Cisco nexus 5548UP switches at site 1 and connect these 2 X Cisco nexus 5548UP switches via GLBP
I would then like to add 2 X Cisco nexus 5548UP switches at site 2 and connect these 2 X Cisco nexus 5548UP switches via GLBP.I would then like to connect the 2 X Cisco nexus 5548UP switches at site 1 and the 2 X Cisco nexus 5548UP switches at site 2 via GLBP.
The best option for load balancing between 2 X Cisco nexus 5548UP switches located at one site and connecting to 2 X Cisco nexus 5548UP switches located at another site.
The sites are connected via a 1GB fibre connection. I am unable to use GLBP until GLBP is supported in further software releases.
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 2 NEXUS switches in VPC. When I create/delete a VLAN gets updated in the same switch, but the VLAN information does not get propagated to the neighboring switch. Revision number remains the same even if I modify the VLAN. Had also tried changing the VTP status to transparent mode & reverting it to client mode but no luck.Have double confirmed on the VTP domain names & password. However the same setup in different location which works perfectly fine.
According to Cisco, Nexus 1010 can host up to (6) Virtual Service blades. I can't find out how many Virtual Supervisor Modules and Virtual Ethernet Modules that make up one Nexus 1000v switches can be supported by each Virtual Service Blades. In other words, how many Nexus 1000v switches can be created with Nexus 1010 appliance?how to configure Nexus 1000v switches with vmware. without Nexus 1010, the standalone nexus 1000v switches was configured from vCenter as an OVF. But how to configure Nexus 1000v switches with vmware where nexus switches are hosted on Nexus 1010 appliance.
I am trying to understand what load balancing method is used on a port channel on a Nexus switch . I have a server connected by a VPC to two Nexus switches. The nexus switches are only acting as layer 2 switches. I have a 6509 connected via a upstream link that does all of the routing for my VLANS. If have a server connected to the Nexus switches and it talks to a server on my 6509 what load balancing happens on the Nexus going across VPC 27 which is a layer 2 trunk going up to my 6509. Is it done on layer 2 or layer 3 flows?
My Nexus shows the default load balancing configurations
Port Channel Load-Balancing Configuration:System: source-dest-ip Port Channel Load-Balancing Addresses Used Per-Protocol:Non-IP: source-dest-macIP: source-dest-ip source-dest-mac
We are looking forward to implement IBM BladeCentre Swiches connectivity with Nexus 2k module.I would like to brief you about my network over as follows:
Currentl Solution : we want to connect the IBM Blade Switches (4) as demonstrated in the attached diagram which will be connected to Nexus 2k module as Ether-channel Access port.
Initially we been proposed by our vendor with this design and Now vendor is recommending us to connect the Blade switch etiher to Nexus 5k switch or directly to 6513 core-switches instead of Nexus 2k modules as they say Nexus 2k modules are only to connect the Edge devices .
We do not have ports available on Nexus 5010 to connect the cables from IBM Blade Centre Switches. Otherthan that, incase if we go ahead and connect the IBM Blade switches as access ether-channel access port with Nexus 2k module what are consequences we have to face realted Spanning tree or any other.
Connecting a legacy Nortel switch (425/450/470/BPS) to a Nexus 7000 via gigabit fiber? I have a customer trying to do it and they say that the connection never comes up. The support on the Nortel stuff is long since expired, so Avaya is not being particularly useful. Apparently Cisco says the issue is "fast link pulse to the BayStack to determine the capabilities of the uplink and the BayStack is returning all zeros." I have not verified this and actually have not yet gotten my hands on the Nexus side of things
I have a lot microbursts in my network and i looking 10G switches with big buffers. Which models have biggest buffers ? I think about 1-2U (nax 4U) switch with up to 60-100 10G ports. Something like nexus 3064 (he has only 9MB shared buffers AFAIK). Besides deep buffers i need also:
- trill or another ethernet ring topology like erps,eapsv2, - Multi chassis LAG, - virtual routers, policy routing - dcb - 40G interfaces will be plus
what is the difference between Cisco Nexus switches and the usual catalyst 3750 switches.I do understand the operating system in both these are different.
When will we suggest using Cisco nexus instead of usual Cisco switches? Also what interface does Cisco nexus like 5548 come with , is it both copper and fiber?
Having a design where an IBM bladecenter has two Nexus 4001i switches and each switch is connected to a Nexus 5k vPC pair, is it possible to configure active-active nic teaming on the hosts (blades) considering that the Nexus 4k switches are unaware of each other and blade has one connection to each 4k over either emulex or qlogic 10G CNA?
We are currently migrating from Cisco 6500 switches to Nexus 7000 switches. I need replicate the following multicast configuration on the 6500 switches in the simplest way so Multicast is functioning on the Nexus 7000 switches.
Cisco 6500 configuration.
ip multicast-routing interface Vlan8 description ip address 10.128.46.2 255.255.240.0
[code]....
how we can enable multicast on the Nexus 7000 switches in the simplest form so this will continue operating.
How to properly power down the Nexus 5000 and the fabric interconnect switches? I have looked up and down cisco's and google web for steps, but they are all coming back with the answer to just disconnect the power cables after you have power down all the windows os and exs servers. Before i do that, I just wanted to make sure that that's the correct way to do it or if there are actual commands that I will need to run on the devices to properly power down. I know that the FI do have a command to reboot, but i need them to completely be power down.
I have a router on which I would like to create a port channel that spans two different Nexus 2248TP switches, and then create a couple subinterfaces on the router's po interface. I've done this successfully on my primary router, but the config doesn't seem to work on the backup router. The primary is running IOS 15, while the backup is running 12.4.25d advanced IP. I do see the trunk come up from the switch side, and my router subinterfaces and po interface show up, however I'm not able to get anywhere from the router. It's not even able to reach other hosts on the same network. As soon as I remove the port channel config and use the physical interface and assign the same address used on the port channel interface, everything works as expected and I have connectivity.

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 am in the process of migrating our existing server farm subnets to our new Nexus server farm and I discovered something I wasn’t expecting. My intention is to migrate our existing legacy server farm which is comprised of for paired 3750 switches off of our core 6509s and onto the Nexus and connect them to the 2232s via multi gig port-channel connections, two port channels per switch stack.
NOTE this is expected to be a temporary move as next year we intend to install additional N2Ks and move servers over to these directly. But to minimize the outage/downtime it will be better to move the subnets and switchs all at once.
These connections would be grouped 1 gig connections as port channels, one from each switch into one of the two 2232s.
Problem I discovered is Cisco does not intend to have switches connected to the Nexus and it immediately disables the ports when they see BPDUs.
I found a config that does work and it does fail over from one port-channel connection to the other but with the limitation that when the original port channel comes back online it does not fail back over to the original one, an acceptable situation for us. But I am wondering if Cisco would support this design if we did experience issues down the road.
The only issue I really see is to get it to work the config is different on the two N5Ks, see the pert config below for the connections. Both are running the same OS

We are currently running Cisco prime 4.1 and want to make sure there is a backup of the configurations from our switches and routers. The VLANconfig is not collected according to the devicestatus dashboard. i am aware there were a known issue with LMS running on a virtual server and vlan not being able to be collected, is this issue resolved? i have tried the various workarounds with TAC support and it hasnt worked. We have the running and startup config collected for our devices when looking at the device status dashboard. does this mean if a switch crashes we can restore the config to a new switch immediately?
i saw there is a version 4.2. maybe this version resolves the issue with LMS on a virutal server? i cannot find the download to upgrade to 4.2 in the support section though.
In my WCS v7.0.172.0, I recently configured the Controller Configuration Backup task. Backups seem to be working fine for the past few days. How do I tell it how far back I want to keep logs, or how many log files to keep before deleting the older ones? Seems like it will just keep on saving the config backups with a date stamp until the TFTP server runs out of disk space.
I'm replacing an older (& failing) RVS4000 v1 with a new V2. I need to minimize downtime. Will a config backup from the old v1 restore properly to a new v2 (all have newest firmware)? There are a lot of tweaks including several VPNs and to do it all manually is not desirable.
I have a Cisco 831 router (c831-k9o3y6-mz.124-5c.bin) that cannot backup the config to a local tftp server. I have seen this behavior on a few different Cisco devices over the years and have never found a solution. The connection is made to the tftp server (in this case tftpd but similar behavior on any tftp server) and a blank file is created on the target machine file system, but the data is never transferred.
The router shows %Error opening tftp://192.168.0.2/router-confg (Timed out) [Failed] The tftpd log shows 5 repeated attempts at the file write.
Connection received from 192.168.0.1 on port 53570 [25/05 11:56:40.922] Write request for file <router-confg>.

This is also stopping me upgrading the image on the router as I cannot transfer in the other direction either.
We are facing issue of continous packet discards On nexus4001L link (int po2) to Nexus5020 switch. Nexus4001L is installed in IBM blade center server and we have FCOE enabled in this setup. [code]
I have been tasked to replace the existing Cat 6500 and 3750 switches by Nexus 7000 and Nexus 2000.I was told initially my boss plans to get 2 x Nexus 7000 and then eventually blow up to 4 x Nexus 7000s.For Nexus, is there a list of tasks / points that i need to consider for building the initial design?
Can i just link the Nexus 7000 like the following?
N7k-A ========= N7k-B | | lots of N2ks lots of N2ks
