Cisco WS-C4948E - four 1/10 Gigabit Ethernet uplink

[evmartinez1]

Hello Community,

I have this question about the implementation of a Cisco 4948E

It's possible to mix on a cisco WS-C4948E a 1G LX port and one 10G SR port, and this can operate properly?

I appreciate your help.

It's possible to mix on a cisco WS-C4948E a 1G LX port and one 10G SR port,

What do you mean by "mix".

Connect a 1G LX port and a 10G SR port  and both operate at the same time, for different services.

Thanks.

Connect a 1G LX port and a 10G SR port  

Connect both ports together?  Not possible and it won't work.

Hello,

It works, like a champ.

Keep an eye out for stability &/or line errors.  The item above in RED should never be any value other than "255".  This means there is a potential line error.

So far... it works with out problems.

Thanks.
