Cisco Switching/Routing :: Upgrade Nexus 7009 6.0.1 To 6.1.2?

Feb 3, 2013

I need to upgrade my core switches at one of our locations (two 7009s with dual sups) from 6.0.1 to 6.1.2.  After looking through the release notes it appears that this will be a disruptive upgrade?how long should I expect for the disruption?  Are we talking a 7009 boot cycle (10 - 15 minutes) or something longer?How many disruptions can I expect?  I suspect 1 per chassis during the failover to the standby but I'd like to validate.Is there any compelling reason to upgrade the EPDL?  From what I can see, again from the release notes, this is only necessary with F2 cards if I were to upgrade to Sup2s . I'm in a healthcare environment and this upgrade will be affecting one of our major campuses so the more info I can get to the managers the more accepting they will be for the disruptions.

Cisco Switching/Routing :: Upload Large ACLs To NX-OS Nexus 7009?

Feb 3, 2013

We are migrating from Catalyst 6509 IOS platforms to Nexus 7009. There's the normal differences in commands which is well doucumented. We do have some quite large files containing ACLs varying from 10's of lines to several 1000's of lines. Our normal upload would be done using tftp and then issuing the command 'conf net' on the the 6509. This is no longer the way to do this on NX-OS. I've tried copy ftp: running-config which works fine for small files but for big ones it takes a long time, in some cases I've see it takes 20-30 minutes. The initilal tftp uplaod to the 7009 seems OK but the copy into the running-config is the bit that takes time and initially I thought I'd killed the 7009!! It did finally come back to the prompt. Are the 7009's simply not designed for large ACLs? I did try the configure session (Session Manager) but I couldn't see a way of uploading a file. I tried creating a new session and then exiting it, copying in a file of the same format and then commiting it but it didn't seem to acknowledge the file (checksum?).

Cisco Switching/Routing :: Nexus 7009 / Maximum Distance For FCOE?

Apr 3, 2012

We are looking to deploy two Nexus 7009 cores at our two datacenters. They are approximately 2 miles apart. We are hoping to have 10G Dark Fiber between the buildings and therefore dedicate a pair for FCOE between the cores using 10G Long Range SFP's. I read that the Nexus 5000 series had a limit of ~3 km for FCOE. Does the same hold true for the 7000 series? I thought I read somehwere that the buffers were larger on the 7000 series and therefore would be able to do ~30 km.

Cisco Switching/Routing :: 6509 - Nexus 7009 Rack Concerns

Mar 5, 2013

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.

Cisco Switching/Routing :: Nexus 7009 Need To Configure DCNM Server To Get License

Jun 18, 2012

We've gotten two Nexus 7009's in and I'm starting to configure them when I found I couldn't add VDCs.  I found there was no license installed but the only licenses I found that came with them are "Cisco DCNM for LAN Enterprise Lic for one Nexus 7000 Chassis".  So my question is this - do I need to configure a DCNM server to get the license pushed to these two 7009s or should there be another PAK for each chassis that I can register and get my enterprise services?

Cisco Switching/Routing :: Nexus 7009 - Syslog Configuration Doesn't Seem To Work For NX-OS

Sep 10, 2012

we've been using IOS for a long time, but are relatively new to NX-OS. We've got a central syslog server that all our devices log to. No matter what we do, we can't get our Nexus switches to log there. Here's my current attempt:
 
Nexus 7009, NX-OS 6.0(1)
 
# sh logging server
Logging server:                 enabled
{redacted}
server severity:        debugging
server facility:        local7
server VRF:             default

[code].....
 
The default VRF is working. I see log entries in the logfile, but nothing arrives at the syslog server. It's not a config issue on the server, because tcpdump shows that no packets arrive from the IP for loopback 0.

Cisco Switching/Routing :: 3750 - Error Message While IOS Upgrade

Jan 6, 2013

Have a small stack of two 3750 routers.  Get the following error message every few secounds:
 
%STACKMGR-4-STACK_LINK_CHANGE: Stack Port 1 Switch 1 has changed to state DOWN
%STACKMGR-4-STACK_LINK_CHANGE: Stack Port 1 Switch 1 has changed to state UP
 
Now I replaced the stacking cables but no joy. It was ok for an hr or so but then the error messages popped up again. Also random links on this stack back to access layer user switches have been going up and down randomly. So I have decided to take the next step and upgrade the IOS.
 
 Although when I try and copy a new IOS I get the following error:
 
%Error writing flash:/c3750-ipservicesk9-mz.122-55.SE6.bin (No space left on device)
 
Seems this image is 130MB while the image that is currently on it is 74MB and free space is 54MB. How do I get the image onto the router? If I delete the current image from flash will that cause the router to stop functioning?
 
Also I noticed there seems to be more than one flash directory. See below:
 
copy tftp: ?
  flash1:         Copy to flash1: file system
  flash2:         Copy to flash2: file system
  flash:          Copy to flash: file system
  null:           Copy to null: file system
  nvram:          Copy to nvram: file system
  running-config  Update (merge with) current system configuration
  startup-config  Copy to startup configuration
  system:         Copy to system: file system
  vb:             Copy to vb: file system
 
The current router image seems to be in flash1 and flash 2 also. Could I delete the image from flash1. Upload it there and then boot the router from flash1?

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 ....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.
