Interface numbering plan on CAT4500E with SUP7-E or SUP7L-E

[jkaras]

We are planning for the first installation of 4500 switches containing these supervisor modules.  I'm trying to determine the interface numbering convention for ports on the supervisors.  Our existing 4500E all have SUP6 modules with twin-gig converters - so I am familiar with the numbering conventions used on those supervisors.  How does this change with the software based selection command "hw-module uplink select" used in SUP7?       

I am in an environment with dual supervisor engines in each chassis.

So, the ports can be Gig or 10Gig. I have not used this sup before, but from the explanation, it appear that the port numbering for Gig and 10Gig is the same.

Have a look at the command reference guide.  It does provide some examples:

I posted this in response to a similar question a few days ago:

Excerpted:

From my experience on Sup-7E, if you use a one-gig transceiver in the supervisor, the port numbering stays the same.  Kind of confusing but at least it's consistent!  Example below:

Switch>show inter status mod 5

Port      Name               Status       Vlan       Duplex  Speed Type

Te5/1                        connected    trunk        full    10G 10GBase-SR

Te5/2                        connected    trunk        full a-1000 1000BaseSX

Te5/3                        inactive     1            full   auto No XCVR

Te5/4                        inactive     1            full   auto No XCVR

Switch>

Hope this helps.
