9400 supervisor

Hi expert

 

I would like to know what could we do with 9400 Supervisor Engine-1 10G port?

1) Stackwise

2) Connect to uplink

3) Connect to downlink

 

If we can perform all of above features, is that mean I no longer need 10G line card anymore?

Hi,

StackWise Virtual Link (SVL) connections are established only through 10G or 40G up-link ports on the supervisor module. You cannot establish an SVL using a 10G port on one switch and a 40G port on the other switch.

 

So, yes if you want to build a Stackwise virtual environment, you have to use the ports from the sup for the VSL.

If you use say 2 10Gig ports for VSL, you can use the other ports for down-link or up-link.

See link for more info:

If we can perform all of above features, is that mean I no longer need 10G line card anymore?

If you only need 8 10Gig ports total including the VSL links, than you don't need any 10Gig module but if you need more than 8 than you need to install a 10Gig module.
