Cisco Switching/Routing :: Nexus 5000 Tacacs

Oct 8, 2012

I have a little problem. My customer is using TACP-PLUS ALPHA (F4.0.3.alpha.v9). Well, the same user than have access to another Cisco equipment, with user test1 by sample, can configure anything in the equipment. But in the nexus 5000, el command "show user-account" indicate just the "network-operator" role. Well, I patch this situation with the next commands:

aaa authorization config-commands default group TACSERVER local
aaa authorization commands default group TACSERVER local
 
Well, when I do a telnet into the nexus, I can shut the interfaces, config and anything. But, when I ingress by console, I can not to configure the interfaces.I understand that the Nexus 5000 the Tacacs configuration is global for VTY and Console (different in the Cisco equipment Routers by sample).

Cisco Switching/Routing :: How To Configure Nexus 5548 TACACS+

Dec 12, 2011

I am working for an Air Force client and am adding a handful of 5548s into their network.  My question is how Tacacs+ is configured.  My hands are tied in regards to testing in an operational environment so I want to ensure the configs are correct prior to deployment/maintenance window and avoid any remote issues.
 
I have read the "Cisco Press - TACACS+" config guide and it was somewhat vague in regards to operational deployment.

My basic NX-OS configs are as follows:

- feature tacacs+- tacacs-server key 7 "002A52xxxxxxxxxxxxxxxx8"- tacacs-server host 128.xx.xx.xx timeout 10- tacacs-server host 128.xx.xx.xx timeout 10- tacacs-server directed-request
 
When I try to set the following command string, aaa authentication login default group tacacs+ local, the NX-OS asks me the input a "server group name".  There are no server groups configured.  Do I need them? Can I get by without configuring a group name because the client probably will not.

The Cisco IOS devices are configured with normal aaa authentication/authorization parameters. Also, do the VTY ports default to sshv2 and the correct tacacs+ parameters with the "transport input ssh" command (not available)?

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.

Cisco Switching/Routing :: WS-C3750X-24S / Continuous High Processor Utilization Involving Hl3mm Process

Apr 3, 2012

We are running a stack of 2 WS-C3750X-24S-E's with IOS version 12.2(58)SE2 and we are seeing continuous high processor utilization involving the hl3mm process.  The stack is configured for PIM Sparse mode, with 2 upstream Nexus 5596'es acting as both RP candidates and as BSRs.  The hl3mm process generally runs at about 19% but can spike up into the 60% range.Symptoms on the 3750X are spiking latency and sluggish CLI perfformance.  I thought at first that we might be running into SDM limits, but the "show platform tcam utilization" show that we are far under the limits of the default SDM template.  Performing the "show ip pim (vrf name) bsr-router" command freezes the system and takes 20-30 seconds to return results.  Similiarly configured WS-C3750G-12S running 12.2(55)SE3 does not exhibit these same issues.
