Cisco Switching/Routing :: 6500 What Happens When A Supervisor Fails
Feb 3, 2010
We've been mocking up a test lab to test VSS on two 6500's. Each 6500 has one sup720 and a 6708-10ge blade and we've established the two 10ge links between the two chassis; the first from the each chassis' sup and the second from each 6708.My question is, what happens when the supervisor fails on one of the chassis?
1. We now have SupA & SupB in the chassis, due to some mistake we have same IOS version but different feature set on them, although we configured redundancy mode sso, in the "show redundancy" we see Operating Redundancy Mode = rpr due to Software mismat, we now need to fix them as same feature set image, if I use "copy sup-bootdisk0:/xxxx slavesup-bootdisk0:/xxx", then write memory, does this cause any service/network interuption?
Available system uptime = 1 year, 1 week, 4 days, 9 hours, 21 minutes Switchovers system experienced = 2 Standby failures = 0 Last switchover reason = active unit removed
[code]....
2. We did a failover test with this status, found that if we triggered supervisor failover, all modules will reload thus the services if interupped. How about after we make the Operating Redundancy Mode as sso, will this behaviour shows again? Or a stateful failover will happens, then modules no need reload?
3. We are using OSPF as our L3 routing protocol, after reference to the configuration, nsf should be enabled, we want to ask in the OSPF-domain nsf should be configured in all OSPF-enabled router or only 6500 which have dual-sup?
4. We also found that the interfaces(3 * Gig & 2 * TenG) in Standby supervisor cannot be use even enabled & configured, is it because we are running rpr mode now or will be the same even change to sso? Before customer have some older supervisor in 6500 non-e chassis, and they can use the standby supervisor interfaces as traffic forwarding, they use rpr-plus mode before, how about in sso mode?
I have a Cisco 6500 series switch with VS-C6509E-S720-10G ,I have two redundant supervisors between two chassis on the LAN with no add-on line cards ?
I need to know if I can use the redundant supervisor 10 Gb uplinks to form a layer-2 Port channel between the two 6500 switches as i do not want to use want to keep the port idle additionally I need more bandwidth between the two switches for my server farm?
I have a question. I have a 6500 with two supervosrs and they both have CATOS. One of them failed and I need to replace. As long as the hardware is the same does the CATOS have to be indentical or can this be different.
I'm trying to configure a egress netflow in a 6500 (VSS) with VS-S720-10G supervisor. I foud some old posts and understood that netflow wasn't supported on 6500 but i found a new document and it seems that netflow is supported in Supervisor Engine 2T:[URL] Does the netflow still not supported in VS-S720-10G? It's weird because the command is supported:
#sh run int vlan 4 Building configuration... Current configuration : 353 bytes ! interface Vlan4 ip address X.X.X.X 255.255.0.0
We bought Cisco sup engine WS-SUP32-GE-3B for 6500 switches 2 nos for redundancy. I have connected 6 systems on each sup engine ports. How to clarify whether both sup engine will forward the data while one is Master and other is standby?

I would like to add a redundant supervisor blade to the 6509 that is in production. Can this be done plug and play and require no reload. Are all WS-SUP720-3B the same as far as memory etc... or can I buy any used WS-SUP720-3B and it will work properly.
we'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 ?
1) Does the 6500 series router support supervisor module redundancy like the 7304 does? IE, can I put two identical sup720 modules in the chassis for failover?
2) Can I use any ethernet interface on any line card on the 6500 series for router interfaces? If not, which line cards work as router interfaces?
3) Differences between the 6500 series and the 7600 series? Can I use a sup720 modules from a 6500 in a 7600?
i have a standalone SUP720, no traffic is passing through it. only one port connected for remote telnet, its kind of backup device.today i checked its log, and there are some wiered message.is it a software bug or my SUP has gone bad? [code]
How the port numbering would be on Sup 7-E and Sup 7L-E? I mean, on Sup-6E and Sup-6LE, if I used a twin-gig converter, I used ports gi3/3,gi3/4,gi3/5 and Gi3/6 [If the sup is in 3rd Slot]. I know there are now 4 ports on the Sup 7 which can either be used as Gig ports or TenGig ports. So, how will the port numbering change ?
I 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.
We have a scenario with 2 chassis, both with 2 supervisor Engine 2T, we try to make a configuration of VSS with the chassis and would link to know if is possible have 2 supervisor on chassis one and 2 supervisors on chassis 2 with VSS?
Router#sho switch virtual redundancy My Switch Id = 1 Peer Switch Id = 2 Last switchover reason = active unit removed Configured Redundancy Mode = sso Operating Redundancy Mode = sso

would like to use the second supervisors for obteind the local redundancy en chassis 1 and 2, this is possible?
the actually version on four supervisors is: s2t54-ipservicesk9-mz.SPA.150-1.SY3.bin
I'm having a trouble with a 4510R+E switch. The WS-X45-SUP7-E supervisors are constantly rebooting, and we can see a 'critical software exception reload' reason. We have checked the logs
______ uptime is 5 weeks, 1 day, 19 hours, 3 minutes Uptime for this control processor is 37 minutes System returned to ROM by reload
[Code]....
What can we do to solve this incident?. Everything was working fine, and suddently the problem arose.
I am trying to understand the implicit limit to the priority queue. I know you can define an explicit policer but if you don't I can't find out what the rate limit really is.
I'm working on deploying a new 4510R+E for our organization. This is my first experience with a modular switch. I'm trying to enable SSO, however in the redundancy configuration mode, the sso command is not available. Is SSO only available with certain software images / licensing levels? [code]
We 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
I 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.
I have configured the VSS in two cisco 6509-E series with only one supervisor engine, but if i configured with two supervisor engine. it is going to common mode. One supervisor engine is 3c and 3cxl.
I have an older 4006 with a Supervisor II+. We now need OSPF support, which the Sup II+ does not provide. I have access to a Supervisor III (WS-X4014), which will provide OSPF support. Question is, are there any gotchas to shutting down the switch, replacing Supervisor Engines and then powering up? What about the flash card? On my current system, it appears that I am only using bootflash: , which is where the IOS resides (see below). Since my startup config is in nvram and my IOS is in bootflash, what's the purpose of the flash card in slot0: ? and where does NVRAM and bootflash actually live on a 4006 ( on the Supervisor Engine?)
sh bootvar BOOT variable = bootflash:cat4500-ipbase-mz.122-31.SGA11.bin,1;,1; CONFIG_FILE variable does not exist BOOTLDR variable does not exist
I would like to add a redundant supervisor to my core 6509. Is this tricky to do? I know they have to be running the same IOS. I am worried if I put the new supervisor in it will write over the exsisting running config.
We 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. At the moment the two supervisors are in SSO mode and after reading many articles it says that when the images are different on the two supervisors they are in RPR mode. 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?
I have "inherited" a Catalyst 4506 with IOS version 12.2(20)EWA1 and Supervisor IV already installed. We recently purchased a second Supervisor IV and I am looking to install this second supervisor for redundancy. Is there anything special with installing a second supervisor or so I just physically install the new supervisor and the IOS will automatically set everything up?
We will install a new Supervisor Engine in our Nexus 7010.One Supervisor Engine is already installed an 1Year old.So the Problem is that both Supervisor Engines may have different NX-OS version.Could this lead to a problem?Does the installed Supervisor Engine "udate" the newer Supervisor engine?
