Why Does a High-Priority Switch Not Become the Master Switch?

Why Does a High-Priority Switch Not Become the Master Switch?

Which switch becomes the master switch depends on the following scenarios:
  • CSS setup: If two standalone switches have the CSS function enabled simultaneously to set up a CSS, the high-priority switch becomes the master switch.
  • CSS merge: If two single-chassis CSSs are merged into a new CSS, MPUs are SRUHs/SRUEs/SRUKs/MFUXs, and the CSS is set up using CSS cards, the switch running for a longer time becomes the master switch. In other scenarios, the high-priority switch becomes the master switch.
  • Addition of a new switch into a CSS: If a new switch is added to a single-chassis CSS, the switch in the single-chassis CSS becomes the master switch.
