4500-X dual active recovery
I have a pair of 4500-X running 3.5.2.E that I am configuring for deployment. I was moving some cables around and got one of the switches int dual-active recover mode. The prompt is Switch(recovery-mode)>. I am sure I can simply reload the module, but what is the recommended procedure? I can't seem to find any documentation on how to recover from this condition.
TIA,
-Jeff
Hello Jeff,
Probably you solved this already... but maybe it would help someone else.
when you connect the cables back, the automatic recovery should start => the switch with Switch(recovery-mode)> should reboot. In my case the switch didnt rebooted only when there was an unsaved configuration. In this case I saved the configuration on both switches (#wr) and rebooted the switch with Switch(recovery-mode)>.

6880-X VSS dual-active detection with Enhanced PAgP
Hello,
I plan to use Enhanced PAgP for dual-active detection for a VSS consisting of 6880-X.
Has anybody tested it?
What about the 6800IA switch - does it have a similar feature that can help the active switch in the VSS to find out if the former standby has become also active?
Thanks, kind regards,
Eduard Gheorghiuhey, i ran this up in the lab, the FEX itself runs dual active detection without the need for PAGP.

4500-X VSS and Dual-Active detection PAgP, using 2960-X access stacks
Hi.
I think this may have been asked before but its not clear to me.
I have 2 4500-X configured as a VSS pair, so a VSL link of 2 x 10Gig between them.
I have a number of Access stacks, built from 2600-X's
I have tried to configure dual active detection, which from what I read it is to use ePAgP or Dual-Active Fast hello Packets.
I do not have any additional SFP's to connect the 4500's together using Fast Hello, so ePAgP appears my only option
When I try and configure the access stack with an Etherchannel across 2 switches using PAgP I get the error -
command rejected by the 2960-x stack
%With PAgP enabled, all ports in the Channel should belong to the same switch
Command rejected (Port-channel11, Te1/0/1): Invalid etherchnl mode
From what I have read, PAgP cannot be configured across a stack, and people are recommending LACP as the method to configure the Etherchannnel, but How does that work with Dual-Active detection PAgP?
When I configuring Dual-Active detection PAgP, and made a couple of the MEC's trusted and configure using LACP active, then tried failing the VSL between the 4500's, each stack went into err disable on the trunk connections.
Question is! Does dual active detection PAgP work over an Etherchannel configured as LACP? or what's my options
Thanks for any help.Hi,
Question is! Does dual active detection PAgP work over an Etherchannel configured as LACP? or what's my options
No, you can't use LACP for ePAGP detection. One option is to break one of the stacks in your access layer and use the switch you want to use for dual active detection individually (not part of a stack) and uplink it to both 4500X switches. This way, you know that the single switch is used for ePAgP detection.

4500X with VSS and Dual-Active Fast-Hello
Hello,
ich have two pairs of 4500X-32, with other word two vss-systems in a test environment. IOS running version is 03.05.02.E.152-1.E2, dual-active detection with a fast-hello link is running. When i pull the VSL connectors to simulate a failure the active switch go into recovery-mode. After the vsl is restored the switch in recovery-mode start a reboot as desired. The configuration is saved and if i repeat the procedure, all is working fine. But when i start the systems the next day and begin to test the dual-active detection again, the vsl port stucks in " waiting to be aggregated" after restoring it. No reboot happens, the only solution is to reboot the switch manually. After that this misbehavior is repeating. Only setting the dual-active detection interfaces to its default, and reconfiguring them for fast-hello dual active detection again brings the feature back to normal operation:
interface TenGigabitEthernet1/1/12
switchport mode access
switchport nonegotiate
dual-active fast-hello
Both vss systems shows the same behavior from time to time, i have no explanation, can somebody help?

Stackwise 3850 for VSS dual active detection
Hello
by means of 3750 or 2960-S stacks, it was impossibile to perform VSS dual active detction
using ePAgP trough a MEC towards different members of a stack.
Here the QA docs for 3850 state it is now supported:
http://www.cisco.com/c/en/us/products/collateral/switches/catalyst-3850-series-switches/qa_c67-722110.html
Though, I'd like to read some confirmation from someone already using it in production or maybe
from some up to date Cisco representative.
I'd like to use lots of 3850 stacks as access switches linked to a 6500 VSS pair. In order to keep
everything redundant i would like to couple VSLP Fast Hellos and ePAgP trough the Stackwise 3850s
but not before making myself sure it's actually supported.
Thanks
francescoFrancesco,
I have deployed stacks of up to five 3850 switches with stackwise and powerstack cables, there are no issues running active/active on redundant links. I recommend using LACP. -
How to avoid Dual Active VSS switches in the network...
Hi Team,
We have 2 nos of VSS switches in the network those are connected with 2 nos 10 Gbps uplink, all access switches are connected to both VSS chassis with dual uplinks, When we removed VSL link between these two vss switches both became active. We have completely Layer-2 network, is that any feature which we can use and avoid dual active scenario in VSS and make any one of the switch in standby mode and all Layer link on that switch will be available in case of VSL link goes down.
I have 3750X series switches are connected to both VSS Core switch It's world be much appreciated if some one provide well document on this and their suggestion.
Your reply will be much appreciated.
Thanks,
VishalThanks for the reply Reza,
Please let me know if we go with Epagp then when VSL link goes down then what would be the result?
1st My there won't be any effect in the network, standby chassis remain in Standby Mode and active in Active Mode?
2nd Active chassis will reboot and became standby and my standby chassis will be Active?
3rd Standby chassis will be shutdown all port except VSL? and only Active chassis will work?
4th Active chassis will restart and shutdown all port except VSL? and standby chassis will be active?
5th ???
Reza it would be much helpful if you please guide how to configured EPagp on 6500 and 3750X switch with "c3750e-universalk9-mz.122-55.SE8.bin (ipservices)" image.

Cisco VSS Dual-active PAgP detection via Nexus and vPC
Hi!
We will soon implement Cisco nexus 5595 in our Datacenter.
However we will still be using a pair of C6500 in a VSS in some part of the network.
Today we are running dual-active detection via a PAgP Port-channel, but those Port-channels will be removed and the only Port-channel we will have is to a pair of Nexus 5596.
Does anyone know if we can run PAgP dual-active detection via this MEC/vPC?
Thank you for your time!
//OlleHi,
The easies way is to connect both links from the 6500s to only one of the Nexus switches. Than create a portchannel on both the 6500 and the Nexus.
The other option would be to connect the 6500s directly together via a gig link and use fast hello instead of epagp.
I would use fast hello since it is supported on the 6500s.

NX-OS firmware Upgradation in Nexus 5548 with Enhanced vPC with Dual Active FEX
Hi All,
Please tell me how to do "NX-OS firmware Upgradation in Nexus 5548 with Enhanced vPC with Dual Active FEX" without downtime for FEX.
The Server are connected to FEX.
Attached the diagram.Hi,
If the 5500s are layer-2 with vPC running between them than you can use ISSU to upgade.
here is doc to follow:
ISSU Support for vPC Topologies
An ISSU is completely supported when two switches are paired in a vPC configuration. In a vPC configuration, one switch functions as a primary switch and the other functions as a secondary switch .They both run the complete switching control plane, but coordinate forwarding decisions to have optimal forwarding to devices at the other end of the vPC. Additionally, the two devices appear as a single device that supports EtherChannel (static and 802.3ad) and provide simultaneously data forwarding services to that device.
While upgrading devices in a vPC topology,you should start with the switch that is the primary switch. The vPC secondary device should be upgraded after the ISSU process completes successfully on the primary device. The two vPC devices continue their control plane communication during the entire ISSU process (except when the ISSU process resets the CPU of the switch being upgraded).
This example shows how to determine the vPC operational role of the switch:

VSS using Pagp+ Dual Active Detection
I am going to use VSS with a C3750 'Access' switch running 12.2(46)SE that supports Pagp+ for dual active detection. Regarding this topology, i have some questions:
1) Does my Etherchannel towards the C3750 stack need to be a Pagp Etherchannel ? Or can it be a fixed Etherchannel (mode on) ?
2) If the Etherchannel needs to be a Pagp Etherchannel before VSS can use the Pagp+ packets, does this imply that i can't use a cross-stack Etherchannel on the C3750, because cross-stack etherchannel did not support Pagp before ? Is it supported on 12.2(46)SE ?It is -very- easy to configure.
Just connect two interfaces back-to-back together, of course, following a different path as your VSL links, then:
interface GigabitEthernet2/4/14
no switchport
no ip address
dual-active fast-hello
end
interface GigabitEthernet1/4/14
no switchport
no ip address
dual-active fast-hello
end
And that's all.

Dual-active detection for VSS via enhanced PAGP
Hello,
What is the configuration needed on an etherchannel PAGP trunk to enable dual active detection for VSS on 4500X ?
I have enabled it on my vss in global mode but I don't know which vlan to allow on the trunk towards my switch in PAGP.
Is it the native vlan that I should allow on the trunk ?
Thanks for the help
JeremyHi Jeremy,
You can allow all the vlans of specific vlans under the portchannel that connects to the access switches. Usually, best practice is to allow only the vlans you are using on that specific access switch.
Dual-active detection command is applied under the VSS domain for the specific portchannel connecting to your access switches. It is not per vlan.
Have a look
