Cisco Switching/Routing :: 6509 / 4900 - Network Down Cause Switching Supervisor With Redundancy
Jan 11, 2012we've had an issue with our network, we have 2 6509 connected with redundancy, which are connected with 2 x 4900 Switches, from which are connected to a ESX Chassis for visualization, the thing is that the ESX stopped working, and the 4900 switches, and the main core were suffering from overload, they hang on it very well, in order to stop the overload, one of the links to the ESX Chassis were disconnected from one of the 4900 switches. The CPU usage from the 4900 and the core(6509) went down below 40%, and then they started to migrate the virtual servers from the chassis to another 2 chassis that were added right after. They were actually working well, but suddenly the 6509 changed to the other supervisor after everything was OK. We were wondering what could have been the cause of this, maybe the virtual servers migrations, maybe the overload from the ESX ? We also had a few question, is there any need to reload the cores every few months as a planned task ? Because the cores have been up for more than 1 year. And also is there any kind of of tool to monitor the CPU status, or the status overall from the cores or the switches ?

Cisco Switching/Routing :: Switching Redundancy For ESXi VMHosts Scenario
May 12, 2013I have the following devices :
-1 VM Host
-2 Layer 3 switches
I would like to provide full redundancy for all vlans being used by VM Guests on the VM Host as well as the management vlan being used by the VM Host.I have created two LACP etherchannel connections on the VM Host. Each etherchannel from the host consists of 4 ports spanning a single NIC. One etherchannel connection goes to a trunked etherchannel connection on switch 1, and the other etherchannel connection goes to a trunked etherchannel connection on switch 2.Switch 1 and switch 2 have an etherchannel connection between them that carries all of the vlans in the topology.Vlan 2 is the managment vlan. Vlans 3, 4, and 5 are vlans that VM guest systems will be using for normal data traffic.
I intend to use switch 1 as the VRRP active router and spanning-tree root bridge for vlans 2 and 3.I intend to use switch 2 as the VRRP active router and spanning-tree root bridge for vlans 4 and 5.The spanning-tree configuration is using multiple spanning-tree with two instances. Instance 1 has vlans 2 and 3 associated and Instance 2 has vlans 4 and 5 associated. I would like to have this topology be fault tolerant to the point where if one of the etherchannel links between the host and one of the switches goes down, (for example, if switch 1 was powered off) traffic will be automatically redirected through the other functional link. I believe that my VRRP configuration would allow for a fairly quick failover of layer 3 services, but I am not certain that my design will be functional at a layer 2 level.
What I am uncertain about is how spanning-tree will converge. I am assuming that the virtual switch on the VM host will not be forwarding any BPDUs being sent by either switch. Would either of the links connecting to the host be considered a redundant link by either switch?Would the link between switch 2 and the host be inactive for all vlans in MST instance 1 during normal operation?Conversely, would the link between switch 1 and the host be inactive for all vlans in MST instance 2 during normal operation? Would all links remain active for ALL vlans? Would this mean that some traffic may travel through switch 2 to reach switch 1 instead of going directly to switch 1?
Cisco Switching/Routing :: ISR 881-SEC-K9 Vs 891-K9 And 2 ISPs Redundancy
Nov 1, 2012have main office of 70 people.Also I have 2 redundant ISP:One give me 20 mbit/s Other only 2 mbit/s and it is my backup ISP.
I have some resources in data center and I need a IPSec VPN to it and some other location. I suppose there will be up to 3-5 IPSec tunnels. I choose Cisco ISR 881-SEC-K9 with one wan port and 4 LAN switch. But know I’m looking for Cisco 891-K9. There is no security bundle for it. But in cisco.com this router is marked Cisco 891-K9 Security router. Does it support security features like VPNs, ZBF, IOS Firewall, NBAR and IP SLA for ISP redundancy? Also if my boss will choose chipper Cisco router 881-SEC-K9. Will I be able to organize 2 ISP redundancy on 4 LAN switch port inside VLAN interfaces because there is only one WAN port?

Feb 20, 2012I have a 4510R-E chassis which currently has a single supervisor 5 installed.
We are now looking at upgrading the supervisor to a Sup6. Now the question is this, can I install the Sup6 into the redundant cpu slot and then perform a failover to get the new switch working without any noticable downtime.
I'm not sure what having a Sup V and a Sup 6 in at the same time will do to the backplane.
Otherwise I have to take the switch down and then install the card and software manually.

Oct 16, 2012We are trying to upgrade the IOS on one of our 6509 switches. We have two 720 10GE supervisors running in SSO. Our procedure is reload the standby supervisor with the new IOS. We understand that you can only use one console connection when in RPR mode so we rely on the active supervisor giving us information that the standby unit is up and running.
The problem we have is that when we do a "show Module" on the switch the online diagnostics for the standby supervisor comes back us unknown. [code] We believe the active supervisor can see the standby supervisor because when we save the configuration we get a message saying that the config is sync'd with the standby router. We have a TAC case raised to investigate. We are upgrading from 12.2(33) SXI1 to 12.2(33) SXJ3

Feb 10, 2013I have a Sup32 that I suspect has faulty NVRAM (e.g., I am unable to "wr mem" on the device - it states resource is busy but no other active connections exist). Prior to replacing the supervisor engine I'd like to take a crack at formatting NVRAM to see if it resolves the issue. This supervisor does not have a CF card installed, thus no Disk0:. Within the CLI, I am presented two options with the "format" command - bootflash: and sup-bootflash:. Bootflash: does not have any data on it, however, sup-bootflash: contains my IOS image. I believe that both of these locations are simply directories within NVRAM.

Oct 8, 2012We are planning to upgrade the IOS on our two 6509E supervisors in the next few weeks. We currently run IOS 12.2(33) SXI1 and are upgrading to 12.2(33) SXJ3.

When you then reload the active supervisor it will reboot all the line cards.
1. Is above correct? Will my line card reload?
2. We also have a FWSM installed, When/If the line cards are rebooted does the FWSM also reboot?
