Representation of all Virtual Chassis members in JWEB

With the recent releases of EX switches, you are able to see in JWEB all the virtual chassis members, regardless of their state.

These are the possible virtual chassis member status:

• Present
• Not Present
• Inactive
• Unprovisioned

Let’s see how this is shown on JWEB and how is it on CLI. FPC1 will transition to all these states.

Prsnt(Present) – indicates that all switches are part of the VC. This means that physical and logical connections are up.

Inactive – indicates that the physical connection is up, but the logical one is not up. The switch will not be an active member of the VC. This can happen in two situations: the member has a different software version and when the VC type is non-mixed, but there are different devices models in the VC.
