Examine the VSX-related configuration of the core layer AOS-CX switch:
A network administrator is troubleshooting a connectivity issue involving the VSX LAG (link aggregation) between the core and access layer switch, during HW replacement of one of the core switches.
Which configuration should the administrator add to the core switch to fix this issue?
In the given configuration, one of the main VSX best practices is to set the VSX system-mac and not leave it blank, as leaving it blank will use the default hardware system-mac. This ensures that in case the primary switch needs to be replaced due to hardware failure, the new switch can be configured with the same system-mac as the original switch. By default, the hardware system-mac is used, which would result in a different system-mac address after a hardware change, potentially causing connectivity issues. Therefore, configuring the VSX system-mac as shown in option A is necessary to resolve the connectivity issues during hardware replacement.
Difficult question, don't see a suitable answer at the moment, therefore exclusion procedure. D: 1/1/45 is for the KeepAlive, which is connected to the secondary peer. So no. C: What is this configuration for anyway? First switch to Int-Range 1/1/46-1/1/47, then switch to an L3 interface and set an Active Gateway there? In addition, the MAC address 12:02:00:00:XX:0Y is recommended for the Active Gateway. So also no D: Makes as little sense as C. Therefore also no, otherwise answer A remains...
A has to be right. "One of the main VSX best practices is to set the VSX system-mac and not leave it blank with default HW system-mac being used"
Page 191 Study Guide: ne of the main VSX best practice is to set VSX system- mac. Do not leave it blank so the default system- mac is used. You want the VSX system- mac to be independent from the physical hardware MAC address. Thus, hardware replacement on the VSX primary switch will not affect your configuration, and so has no impact on the VSX secondary because the cluster ID remains unchanged [Aruba Networks]
Correct answer: A Can't be D as the gateway specified belongs to KA network
A is correct
didi anyone notice ports 46,47 are not joined to LAG 256 and that could be the main issue ? all answers seem wrong for this question
i think the key issue is LAG256 has not been added to 1/1/46-1/1/47！ here perhaps they want to ask the best practice for hardware change, to set the system-mac manually on the VSX primary switch... have to choose A...
Lab04 - VSX best practice guidelines: • On the VSX primary switch, set the system-mac manually. This will ensure that in case this switch needs to be replaced due to hardware failure, the new switch can be configured with the same system-mac as the original switch. By default, the hardware system MAC is used, which would result in a different system MAC address after a hardware change.
