VSS Quad Sup Question

Hi,
We have two chassis 4500's with Quad Sup's. They are currently in VSS mode with Secondary Sup in each Chassis in Rom mon.
Our problem is contained to the chassis themselves, not the VSS.
When we do power failure test, the chassis reboots but the now rom mon mode supervisor powers up and becomes Primary. It does not have the configuration of the Primary Supervisor.
So we need to know -
1. Does the config get synced, if not do you have to manually load config from primary sup if it fails.
2. Can you force a specific supervisor in a chassis to be Primary.
Thanks

When we do power failure test, the chassis reboots but the now rom mon mode supervisor powers up and becomes Primary. It does not have the configuration of the Primary Supervisor.
Without VSS, if a chassis has dual-supervisor card, the configuration of the primary card is always synchronized to the standby card. Same goes with VSS (single- or dual supervisor card per chassis): The configuration is synchronized to all "on-line" supervisor card.
The only time this doesn't happen is when the standby card is either in ROMmon or couldn't join the "redundancy" (of a dual-supervisor card per chassis or VSS) due to incorrect IOS.

Vss quad sup support for 4500 series

Hi all
I'm looking at at 4507r+e with dual supervisor 7
I want to run vss, however does it support quad supervisors?
I hear the second one will have to be in rommon?
In a failover how would I get the 2nd supervisor working ?
Would you need to manually boot it?

Have a look at the config guide:
Quad-Supervisor (In-chassis Standby Supervisor Engine) Support
The Catalyst 4500 series switches support dual supervisors in a redundant chassis, which can be configured for SSO or RPR mode. However, when a chassis is running in VSS mode, it supports a second supervisor engine, but only in rommon mode. In-Chassis-Standby (ICS) can not participate in control, management, or forwarding plane functioning. This makes ports on the supervisor engine in rommon mode available for forwarding although it neither participates in any switchover nor provides protection against any failure. In VSS mode, an In-Chassis-Active (ICA) supervisor engine participates in VSS control/ management operation and manages ports on the supervisor engine in rommon mode.
If the second supervisor engine is inserted in a redundant chassis, the following information applies:
•It must also be manually configured for VSS mode, i.e., it must have been converted from standalone to VSS mode previously. If you insert a supervisor engine that was not configured for VSS mode, it will disrupt the operation of the ICA supervisor engine. If it was previously configured, automatic boot must be disabled (i.e., to boot only to ROM Monitor) with the confreg command in rommon.
The supervisor engine does not takeover or boot automatically when the ICA supervisor engine fails. A manual boot up is required to make it participate in VSS; it then functions as an ICA supervisor engine.
More details on rommon commands are found at this URL:
http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/15.1.2/XE_340/configuration/guide/rommon.html#wp1013959
•A supervisor engine's conversion from standalone to VSS occurs per engine. If two supervisor engines exist in a chassis, one should be retained in rommon or removed, before conversion occurs. You can convert the second supervisor to VSS mode while the first supervisor is removed or in rommon, with the additional step of setting it to "boot only to ROM Monitor." When both engines are converted to VSS, they can be inserted into the chassis together and re-booted.
•Booting a chassis with two supervisor engines configured for VSS causes one of the engines to become the ICA and participate in VSS. The other engine, which becomes the ICS, will continuously reload. The secondary supervisor (the ICS) must be configured to "boot only to ROM Monitor" with automatic boot disabled.
•When the ICA fails, the ICS doesn't take over because ICS support of SSO or RPR mode is unavailable. ICS (the secondary supervisor) must be booted manually to become the ICA and manage the VSS operations. For this to happen, the former active supervisor engine must remain in rommon mode.
•ISSU support requires ICA supervisor engines on both chassis. The ICS supervisor engine does not participate in upgrade or any forwarding operations.
•Because ICS supervisor engines do not communicate with ICA supervisors, VSS and other configurations must be done at conversion time on the ICS. If not done or the configurations do not match the necessary VSS parameters (like, SwitchId, Domain, and VSL configurations), it cannot form a VSS when ICA goes down and ICS is booted manually. You can, however, enter these "bootup" commands to make it join an existing VSS domain.

6509E VSS w/Quad-Sup 720 - Traffic Forwarding Issue

Hello all,
I ran into an interesting problem yesterday evening while performing a quad-sup upgrade to an existing dual-sup 6509E VSS architecture. Unfortunately, the expiration of my maintenance window forced me to roll back the changes before I had the opportunity to truly discover the root issue, however, I wanted to post my experience on Support Forums with the hope that someone else has run into it before.
The customer I was working with has an existing dual-sup (720) environment operating in VSS mode. Both sup's were installed an operational in slot 5 of each chassis. The switch ID's had been assigned as 1 and 2, and the VSL was comprised of the two 10GE interfaces connected between each of the sup modules (1/5/4-2/5/4 and 1/5/5-2/5/5). The customer wanted to increase their intra-chassis redundancy by installing two additional sup 720 modules in slot 6 of each chassis, and adding these 10GE interfaces to the VSL.
The overall upgrade went very well. I began by physically installing an additional sup 720 in slot 6 of the VSS standby chassis, and the sup module came up into RPR-Warm status (which is the desired state). I then physically installed an additional sup 720 in the VSS active chassis, and it too came up into RPR-Warm status. After reviewing the VSS redundancy state, I determined that everything looked good, and proceeded to add the additional 10GE links (1/6/4-2/6/4 and 1/6/5-2/6/5) into the VSL configuration. I then physically connected the additional VSL links (but shifted them around as to achieve diversity between the chassis (1/5/4-2/5/4, 1/5/5-2/6/5, 1/6/4-2/6/4, 1/6/5-2/5/5). I then reviewed the VSL link state and EtherChannel state, and everything looked great.
At that point, we were pretty much done with the switch configuration, and proceeded to verify that server/network resources were not affected. I found that there seemed to be an issue sending traffic across the VSL. For example, some physical servers connected to switch ID 1 were having a difficult time communicating to physical servers connected to switch ID 2 (this customer is still working on dual-homing hosts). I looked at all of the obvious things - physical VSL interfaces, EtherChannel status, etc., and everything looked good. I then proceeded to remove physical VSL interfaces from the configuration, eliminating those that were added that evening (e.g., all interfaces except the original 1/5/4-2/5/4 were removed) - nothing. At this point, I was 10 minutes from the expiration of the maintenance window and was forced to roll back. It wasn't until the newly added sup's were physically removed from the chassis that the issue subsided. That said, I was able to conclude that the VSL wasn't the problem at all, but perhaps the installation of the sup's was??
All of the sup 720's were running 12.2(33)SXI6 code, which I had verified to be a safe harbor version (although there are known bugs, none appear to be related to this issue).
Has anyone run into this issue before? Any thoughts would be appreciated!

You bring up VSS outside of the current environemnt. Create all vlans with a spanning tree priority higher than the existing.
Create all the vlan interfaces and leave them shutdown.
Connect the existing core to the new VSS core. Make sure that all vlans are properly crossing the trunk between old and new cores. Depending on how you're routing is set up, you might need to create a vlan to use for routing updates only.
At this point, you can start changing spanning tree priorities to move the root of the vlans to the vss. Once these have been moved, you can start to manipulate hsrp.
Whichever switch has the backup interface, shut those interfaces down. After this is done, shut the vlan inteface on the old core and no shut on the vss. Since vss doesn't use hsrp, it's hard to manipulate the vss since you want the vlan interface to be the previous standby ip.
Flipping the vlan intefaces shouldn't cause any issues. I've done this method several times in large hospitals with no issues.
Once you have the vss running, you can move the access switches 1 link at a time. Make sure you're running rapid pvst.
The method I've used for this is to create a port channel on both the access switch and the vss. On the vss, you can assign the interfaces into the port channel immediately. On the access switch, disconnect one of the interfaces that goes to the old core. Add the disconnected inteface into the port channel then plug it back in. It should come up as the only member of the etherchannel. After you verify this link is up properly, perform the same with the second uplink on the access switch. When you plug it in, it should join the channel and you should be fine. With rapid pvst, nothing should be noticeable when the links block and unblock.

EFSU and quad-sup

Hello,
I need help on this. I have two Cisco Catalyst 6807 with quad sup 2T. I'm trying to upgrade to latest IOS with the following procedure :
http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst6500/ios/15-1SY/config_guide/sup2T/15_1_sy_swcg_2T/enhanced_fast_software_upgrade_efsu.html
I'm upgrading from IOS 151-2.SY1 to 151-2.SY2.
So I'm doing this :
# issu loadversion bootdisk:s2t54-adventerprisek9-mz.SPA.151-2.SY2.bin
At this point, the standby-ICS sup reboot fine with the new IOS.
Then the standby sup reboots and after several minutes I always get this :
* %ISSU_PROCESS-SW1-3-ABORT: Starting abort sequence, reason: LOADVERSION: New Standby has failed to respond
At this point, the process fail and do a rollback.
So my question is, does eFSU supports quad-sup ?
Thanks

Hi Richard,
i dont think the whole switch will go down since it falls back to Chassis A Supervisor 2 and Chassis B supervisor 2 will be VSS standby Sup and Inchassis active for Chassis 2.
Please read the Supervisor Switchover Events under the below link for a better understanding.
http://www.cisco.com/c/en/us/products/collateral/switches/mgx-8800-series-switches/white_paper_c11-729039.html

C4500 VSS quad - incorrect config synchronisation

Testing two C4510R+E chassis VSS in quad supervisor 7-E configuration.
All 4 sups. had the same basic configuration – converted to VSS and added VSL ports (same in each chassis).
During testing I inserted one more linecard to each chassis and added one port from the card to VSL. All worked fine. Then I removed active sup., booted previously ROMMON booted sup. to IOS and config was synchronized from ACTIVE to STANDBY sup. and VSL config was updated. Again, all worked fine.
But the I realized incorrect seting of calendar so I began to change UTC calendar time from factory to local setting. Change active - active synchronizes to standby, switchover, boot second sup. etc. But after second switchover, on ACTIVE sup console appeared warning, that config was synchronized from STANDBY to ACTIVE!
First I was thinking about version revisions of configuration – higher revision would have higher priority, but did not find any information about it so could the time synchronization be problem.? I was changing approx. +7h from factory settings.
Does anybody have any experience with this behavior?
Note: the log bellow is from Active sup. that had factory time setting and Standby sup. (probably) had updated time.

975X quad core question

Hey guys, I have a 975X Platinum Power Up Edition, and I'm trying desperately to avoid having to replace it. From what I can tell, the Q6600 or Q6700 (depending on which I can find the best price on), is the best CPU that the board supports (65nm limitation is killing me!).
Here's my question: do I need to flash the BIOS to add quad core support, or is it strictly a plug and play deal? I can't recall ever having updated the BIOS, so I actually don't even know which version I'm running. I just checked it, and I didn't see "BIOS Version 7.0" or anything, so... ?

Quote from: Rake on 23-April-09, 09:05:22
This is what my screen shows me at first (cut off number is BIOSv1.06.63):
And then, for about 0.2 seconds, this flashes onscreen:
And that's it.
That seems to suggest that I need BIOS 7.6. Is that correct?
You are looking at wrong places, check the images again!

PowerMac G5 Quad reformat questions

Hello,
General questions on reformatting a PowerMacG5 Quad. Another department sent over this tower, sans any install disks (or monitor or keyboard for that matter). I'd like to wipe the system and start from scratch -- do I need a specific install for a Quad G5 or just a retail system. I have a boxed Tiger 10.4 retail, would that work on the G5 Quad (never had a quad system before). Also, for disk maintenance, can Disk Warrior be used on a quad?
Thanks

OEM disk, or later version. Whatever will boot your system. Sometimes hardware (video) upgrades can change minimum requirement.
Was early '06 or late '05 only 10.4.2? by August it was 10.4.7 territory.
Retail, there was 10.4.3 DVD (some customers couldn't even connect to their LANs with 10.4.0) and then 10.4.6 DVD came out with more improvements. So there are various flavors retail Tiger. Just as there is now 10.5.6 and was 10.5.3 and 10.5.0.

VSS with SUP 2T

Dears
I have 2 no's 6509 chassis in VSS with sup2t and ASA-SM installed, as I know that the dataplane is active for both switches so the cisco says that I we will get the throughput of 4.0 tbps but the ASA-SM only supports 20 gbps, and all vlan interface are created on ASA-SM module so there all bottleneck happens, Customer is not ready to move any vlan interface to the 6509 MSFC by bypassing ASA-SM.
so how the ROI should be explained to the customer of SUP2T with ASA-SM if installed.
thanks

Dear Jon,
1) It's an ASA service module inside the 6500 chassis and not the ASA standalone appliance. All Network in the world will reach to a place where they have to push the traffic to firewall where definitely the speed will reduce from tbps to gbps and not every organization can place high end firewall with 10 GIG ports with better throughput, so from your reply what I understand is that VSS benefits only with an intervlan routing.
Bear in mind that if most of the traffic is routed to remote networks then your uplinks also become bottlenecks although you could probably get more uplink capacity than your ASA gives you.
how to get more uplink capacity ??
Of course there are obviously other benefits with VSS in terms of ease of configuration, redudancy etc. and it really comes down to your priorities.
can you list more.
2) I have read the SUP2t Datasheet saying per slot 80gbps I hope it is half duplex becz if I put 16 port 10 gig module the bandwidth will reach till 160 Gbps , please correct ???
3) I have attached 4 port 40 Gbps module datasheet, so what it says that with all ports sending traffic will reach to 160gbps per slot if a chassis populated with 40 gig module and all set to send traffic with full bandwidth than it only reaches to 1.7 tbps which is less than 2tbps.
4) I have another doubt that 6500 chassis backplane support only 40 gig so incase if the module is sending traffic with 160 gbps than how it handles.
Thanks

Quad Firewire question

Hy, my new quad seems to work fast and quiet.
But I've discovered that syteme profiler is listing an "Unknown device" in firewire section even if there is no firewire device plugged.
Did you noticed the same thing on your quad ?
btw all my firewire devices are working without any problems.
best regards.

Yeah... I've got two devices plugged in so I've got two empty ports... I guess those are the "unknown devices"?

Quad Core Question

We are building a new system. The last system we built was a dual quad core with 8 Gigs of ram, Quadro FX 3500, and XP 64-bit. Every time we opened After Effects and Photoshop it crashed and locked up the system. We changed the OS to XP 32-bit, dropped the ram down to 4 Gigs. The system is working better, but not where we would like it.
On the second machine we do not want to have the same issues. Does anyone know what we can uses to get the most bang out of this system. After Effects CS3, Premier Pro CS3, and Photoshop CS3 are the main programs we are using.

David has a point, though MS will support XP64 with patches and hotfixes until 2011. Unfortunately switching to Vista 64 will not guarantee any betterment. The point everything is pivoted around is driver support and on the system you were experiencing problems, very likely the graphics card is the culprit. NVidia is always behind in supporting x64 systems and in addition, it really seems to depend on the specific sub-model of a card. If you search this forum for threads on issues with NVidia cards or Vista for only the last week, you will find several threads... In that light, giving concrete advice is rather difficult. I can only report that I have a FX5500 on a dual quadcore E5345 and the system runs perfectly for a year now. However, this has been a prefab computer of our local Fujitsu-Siemens brand R-series workstations, so I wouldn't really expect otherwise. ;-) Perhaps you should consider taking that same route. I can reasonably assure you that HP workstations are just as well thought out and put together.

3.33GHz Quad-Core Question

I'm wondering why does my 3.33GHz processor show as a 3.32GHz in "About my Mac" Also does anyone know exactly what intel processor this is? W3580? Thanks

The speed is nominal because not all crystal oscillators generate exactly the same frequency. Your processor's speed is based on the bus clock times a multiplier. If the bus clock is off by a slight amount and the multiplier is fixed then it results in a slightly different clock speed for the CPU. For example if your bus clock were 1.066 GHz and the clock multiplier is 3, then the CPU clock speed is 3.198 GHz. But if the bus clock were 1.067 GHz then the CPU clock speed is 3.201 GHz. Your model uses a 1.333 nominal bus clock with a 2.5 multiplier which results in a 3.33GHz CPU clock speed. If your bus clock were 1.328 GHz, then the CPU clock speed becomes 3.32 GHz. The ratings you read are essentially "nominal" but may vary slightly from machine to machine. They will also tend to be changed by changes in power supply voltages and frequency.

Asus CG5270-BP003 Desktop Quad 4 Questions PLEASE HELP!

Hello, considering the ASUS CG5270-BP003 desktop comuter for purchase. Can anyone tell me, what model number the motherboard is? Is the graphics integrated? Thanks!!
-Heather

Thanks for the help on the graphics, so it is an actual pcie card, not a chip built into the motherboard? Sorry, but the specs say "UP TO 1 GB MEMORY" which makes me suspect.
The reason I need to know what model the motherboard is to find out if it is compatible with a certain version of linux i run in the office. Also, can anyone tell me if they would open a box in the store so I could check whether the HDD and CDROM are SATA or IDE?
Thanks a ton for the help.

Clients not getting DHCP in VRF

Good morning -
We have devices in the global routing table (not in a VRF) getting DHCP addresses without issue. The SVI is configured as such:
interface Vlan2301
description BLUE
ip address 172.19.68.1 255.255.255.0
ip helper-address 10.4.16.222
interface Vlan2512
description RED
vrf forwarding RED
ip address 10.217.5.1 255.255.255.0
ip helper-address 10.4.16.222
Clients in BLUE are getting DHCP but clients in RED are not. If I statically assign an address I have connectivity and can reach the DHCP server (which is also DNS server; with a static IP in VLAN 2512 I can do name resolutions for example).
I am at a bit of a loss. Is there anything special I need to do for VRF IP HELPER-ADDRESS configuration? A capture on my firewall interface shows the DHCP server is trying to reply - it is like the helper-address is not forwarding the dhcp reply (or is not getting it)

Good morning -
I have a pair of 6513 in a VS40 (VSS quad sup) connected via L3 MEC to a VSS pair of 4500X. Active to Active and Standby to Standby connected in a L3 MEC port-channel that is also a vnet trunk:
(Core)
interface Port-channel5

The interfaces are all using LACP mode Active inside the channels
On the 4500 we have a global routing table and a vrf. Both have helper addresses pointing to the DHCP server which is extranet service behind the 6513 Core.
interface Vlan2301
description Global Routing Table

ip helper-address 10.4.16.222
DHCP for the Global Routing Table subnet works. DHCP for the VRF does not.
What is interesting is if we shut down the link that is connected to the standby 4500 (Te2/1/1) DHCP starts to work for the VRF.
Using <debug ip dhcp server packet detail> at the 4500 here is what I am seeing.
When both links are up and DHCP is failing for the VRF:
Mar 10 20:02:02.419: DHCPD: BOOTREQUEST from 0100.1a6b.3a56.13 forwarded to 10.4.16.222.

When I shut the Te2/1/1 link down in the L3 MEC at the 4500 DHCP starts to work for the VRF RED:

It is like there is a bug that is treating the L3 MEC as a L2 MEC when both links are present; or the VNET trunk is not being processed correctly.
Has anyone else used a L3 MEC with a VRF and a DHCP helper with success? Is this a bug?
03.05.01.E is the code we are running on the 4500X-32(SPF+)
This is also with TAC but I thought I would share with the community in case anyone else has a similar environment or if Cisco experts want to comment.
