• ESXi SC Nic - Active or standby

  When building a new ESXi server and to implement the vswitch Management Network (service console) is a best practice with regard to this configuration with 2 adapters as active/active 1 active and 1 mode? If so, what are the benefits and the risks of doing anyway.

  Thank you very much

  Scott

  With 2 network cards dedicated to network management, I always have re them as active/active. Unless there are special reasons (e.g. 1GBit prod + 100 Mbit backup) I don't see a reason for a standby configuration.

  However, what I like to do when there is a VLAN is to run the VMotion network on the same vSwitch and configure groups of ports for network and VMotion management as active / standby to ensure that each service has its dedicated NIC - in normal operation -

• NIC team Active standby failover - how to see which physical adapter is actively used at a specific time by a VM or VMKernel port

  Hello, simple question.

  I have a vSwitch with two portgroup VMKernel. The switch is connected with two network adapters. The failover policy is set at the level of Portgroup. PG1 has active nic1 and nic 2 in standby mode. PG2 nic 1 standby and active NIC 2. I want to know via cli or gui, command which nic is actually used for a portgroup at a specific time. Is this possible?

  Thank you!

  You can see the active uplink for each vNIC in the network view (press 'n') with esxtop (r):

  

• The networking redudancy, 2 network cards, active/active or active / standby?

  I have two network cards available for my management network.   More 'design' documents that I saw an active set to NIC and the other in standby mode.  What is the advantage of this approach compared to their definition both active?  Suppose I have no limitation of NIC and these 2 ports are dedicated to management only.

  If you have no other exchanges on this vSwitch then you can leave them as an asset with no problems.

  Sometimes, the VMK vMotion interface is placed on the same vSwitch as VMK and if yes, it is good to separate them for different vmnic with active / standby.

• Is it necessary to buy two packs of licenses to set up a cluster active / standby HA with two units of TZ300?

  I need a cluster active / standby and I think I will need to buy two devices and only CGSS. Am I wrong?
  Why there is no TZ300 HA Unit regarding the unity of TZ500 HA and TZ600 HA unit?

  Thank you

  Angelo

  Yes, you are going to have to buy two devices and licenses only to your main unit. The only reason why there are TZ500 and 600 HA units because generally these are units that especially customer implement an HA pair because of the power they have.

  A TZ300 and 400 are wanted over a smaller model of business that usually gives rise to not have an HA pair so their isn't a specific unit of HA.

  These HA units are not different from any other unit, they are simply locked as part of a wise pair HA license.

• Procedure to upgrade (Active-Standby) ASA

  Hi all

  I just want to check if our upgrade scheduled SAA causes no problems during the procedure.

  Material: ASA5525-X

  Setup: Active standby

  We intend to be upgraded the first start, after that, is the day before still will to resume after we force a failover him so that we can then pass the main firewall.

• Cisco ASA CX active / standby

  Hello friends

  One of my clients has a couple of ASA 5545 work quite well as active / standby failover. But the configuration that is not copied to the secondary unit is CX. Do you know how to get it? Please, do not hesitate to request further information, comment or document will be appreciated.

  Kind regards!

  The CX configurations are not part of the active reserve ASA replication.

  How to synchronize the configurations of CX is to use PRSM (first Security Manager - product under separate license, not the one provided with the CX) running on a virtual machine in device mode.

  Reference.

  Once you find out what pair CX with a PRSM "out of area", all configuration changes are deployed both to the pair.

• Cisco ASA active / standby Mac addresses

  Hi all

  Please advise on the underside.

  Say that I have to active / standby. I have two interfaces on each firewall configured as below

  For the primary (active)

  interface GigabitEthernet1 / 0--> Say burned in mac address is 6c41.6bb0.1111
  nameif test1
  security-level 0
  10.1.1.1 IP address 255.255.255.0 ensures 10.1.1.2

  im int 2/0

  Test2 nameif--> Say burned in mac address is 6c41.6aa0.1111
  security-level 0
  10.2.1.1 IP address 255.255.255.0 ensures 10.2.1.2

  For secondary school (currently idle)

  interface GigabitEthernet1 / 0--> Say burned in mac address is 6c41.6bb0.2222
  nameif test1
  security-level 0
  10.1.1.1 IP address 255.255.255.0 ensures 10.1.1.2

  Test2 nameif--> Say burned in mac address is 6c41.6aa0.2222
  security-level 0
  10.2.1.1 IP address 255.255.255.0 ensures 10.2.1.2

  According to my understanding of the DOC.

  To transfer traffic, other devices will use the main unit mac address and IP addresses.

  Please consider under the scenario:

  My primary unit has failed and secondary took over as active unit.

  Primary (standby)

  Secondary (active)

  secondary Q1) so now will use the IP address and Mac address as below? Please confirm

  10.1.1.1 & 6c41.6bb0.1111

  10.2.1.1 & 6c41.6aa0.1111

  Q2) I believe that the ip address of the primary (Standby) in aid will be

  10.1.1.2

  10.2.1.2

  It will use what mac addresses? What is the BIA of the secondary unit? Please notify

  Thanks in advance.

  Q1 Yes), IP address and the MAC will be moving to the new active unit so no matter who the network except the switch will notice failover event

  Q2) Yes, primary (watch now) will use IP addresses and MAC addresses available for secondary:

  6C41.6bb0.2222

  6C41.6aa0.2222

  Kind regards.

• Safe way to restart the pair active / standby

  Hello

  I need to reboot my ASA5520. We have a pair of active / standby and I want to make sure they come in playing well and not in a fierce struggle.

  Any advice on how to reload these machines and optimize operating times?

  Thank you

  Pedro

  Pedro

  If you are not bothered in regards to he who becomes primary then simply pick one, reboot, wait until it has developed and then reload it.

  As long as you have properly configured failover, there should be minimal downtime, just the time it takes to switch when you reload.

  If you want to stay as the main primary school, then you need to recharge it first, let it come as standby, then reload the other and the former primary school will now become primary.

  Note that recharge the standby is firstly the best approach simply because you then have only a failover IE. When Eve comes backup and resumes, it's a standby feature then you recharge the primary here will be a failover.

• Active / standby ASR9000v ICL

  Hello world

  After reviewing the documentation for the 9000v, I wonder if it is possible to configure the following scenario without using nV Edge. I have a pair of ASR9912 that are configured as standalone units. We received 3 ASR9000v which we configured in a scenario of the active / standby as part of a requirement of the customer.

  There is a pattern in this link: https://supportforums.cisco.com/document/9868421/asr9000xr-using-satelli... that shows the scenario, but it seems like a VSS deployment. In the same document, section 13 describes a Dual-host configuration. I wonder if that's what I'm looking for. Interfaces GigE on the system of 'sleep' will be in a break state? I'd be worried about some conflicts.

  I'm not the second 9912 upward and going until mid-January because of the power and the grid space, so I can't test until then.

  Has anyone successfully deployed this scenario without using nV Edge?

  Thank you.

  -Dominique

  DOM,

  We prefer that you evaluate advanced bifocals, which is a new feature. You will not need to use NV EDGE and we are actually calling customers of this technology to something more standards based. Take a look at the following:

  Hello

  I'm deploying an ACS connected to an RSA AuthManager (that is connected to an Active Directory domain)

  I create several groups within the Active Directory server, I try to give to users for their groups different access rights.

  I tried to define an access policy "NetOp/NetAdm" and two authorization rules:

  Rule-1 AD - AD1:ExternalGroups contains all dir. INTRA/groups/NETOP 'Auth for net operators' 0

  Rule 2 AD - AD1:ExternalGroups contains all dir. INTRA/groups/NETADM 'Auth net admin' 0

  Default: refuse

  In the identity, I have configured the RSA identity source, so that users get authenticated by the RSA Authentication Manager.

  But I still refuse to get access, RSA authentication is successful, but the group membership, active directory does not work, even with the unix attributes or group principal defined for the user.

  My question is this valid configuration scenario? Is there another way to define several profiles according to the Group of users of external source?

  The stages of monitoring:

  Measures

  Request for access received RADIUS 11001

  11017 RADIUS creates a new session

  Assess Service selection strategy

  15004 Matched rule

  Access to Selected 15012 - NetOp/NetAdm service policy

  I think you need to do is to create a sequence of identity with RSA as a selection in

  Authentication and recovery research list of attributes and AD in the additional attribute list recovery research. Then select this sequence as a result of the politics of identity for the service

• ASA 5520's active / standby, do not sync AnyConnect Profles

  I'm working on two ASA 5520 configuration in a configuration active / standby.  I have almost all the same between the two units for AnyConnect work waiting for both of the following:

  AnyConnect Client profiles

  AnyConnect Client software

  If I download the software manually to the standby unit I get warning against them are not synchronized, and on the active unit if I do a 'writing' standby does not copy the profile or the software.  Anyone has any ideas on this?

  Thank you

  Hello

  Bug CSCsr31403

  When you configure the ASA in a failover pair, you must manually copy the AnyConnect and CSD images for the primary and the secondary ASA.   You must also do the same for the Anyconnect profile file if you use it.

  Either force the ASA shall become active and copy the files to the new ASA assets using ASDM or copy files directly from the console ASA ensures using tftp or ftp.

• ASA (Active standby) site-to-Site VPN Question

  Hello

  I had the question as below

  Site A - 1 unit of VPN Netscreen firewall

  Site B - 2 units of ASA VPN firewall

  

  I'm trying to set up a VPN from Site to Site, but a problem with the configuration of the active standby.

  Initially, I tried Site A 1 unit Netscreen and Site B 1 unit ASA vpn site-to-site. There's no problem.

  but joins another ASA at site B and configure it as active / standby then I saw a few questions that I need help from here

  Things that confuse me.

  (1) do I need to use 2 public IP address on the SAA? (public IP for assets and the other a public IP ensures IP. it seems like a waste of the public IP address.)

  (2) link failover and dynamic failover can be configured on the same interface?

  Please help in this case, configuring VPN from Site to Site with active configuration / standby.

  just to add to this,

  just be careful when you dedicate an interface for dynamic failover, make sure that it is the highest capacity, or at least the same ability as an interface offers th

  so if you use concert for passing traffic interface uses a concert for dynamic failover port, several times we saw people using the management for steful interface when they ports of concert and they run into issues where the dynamic function does not work as expected
