VSS Interface question

cowetacoit

I'm planning a maintenance window to deploy VSS on a pair of 4506-Es. I'm in the process of building the configuration file since the naming convention changes to "interface-type switch-number/slot/port".

My question is after the VSS pair is formed.....what does the second switch's interface naming look like? Since they are both 4506-Es i'm wondering if the supervisor will still be considered a Slot.

example:

1/1/x     Supervisor

1/2/x     Linecard

1/3/x     Linecard

1/4/x     Linecard

1/5/x     Linecard

1/6/x     Linecard

2/1/x     Supervisor

2/2/x     Linecard

2/3/x     Linecard

3/4/x     Linecard

3/5/x     Linecard

3/6/x     Linecard

Yes, the supervisor port(s) on the second switch will be seen as 2/1/x. They have to be to be distinguishable from the other switch's supervisor port(s).

As Jon also noted, the naming convention will change.  So, for example

switch 1, blade 4 and port 28 will look like this:

1/4/28

the same port for the second switch will be

2/4/28

same for Sups

primary sup 1/5/4

back up sup 2/5/4

and so on...

there is no 3/x/x or 4/x/x, because for VSS the max is 2 switches.
