QuestionQ14

Network Resiliency and virtualization

You need to describe VSX to a colleague. Select the three items considered best practices for implementing VSX on AOS-CX.

Choose three
  • A Allow VLAN 1 on all trunks in order to facilitate ZTP for downstream devices.
  • B Set a VSX system-mac manually to simplify switch replacement of the primary if required.
  • C Adjust MTU on the ISL link to permit transport of jumbo frames if endpoints require it.
  • D Configure all VLANs manually on both the primary and secondary nodes before enabling vsx-sync.
  • E Adjust the default keepalive timers to match or exceed the ISL hold interval.
  • F Use a direct L3 circuit for the keepalive connection between both nodes.
Explanation

A manually configured common VSX system MAC prevents control-plane identity changes and associated traffic disruption during primary-switch replacement or recovery. ISL member links must have an MTU large enough to carry jumbo frames when the attached environment requires them; AOS-CX drops frames larger than an interface MTU. VSX keepalive traffic should use a dedicated Layer 3 connection, separate from the ISL, so peer liveness can still be determined if the ISL fails.
